ZETEYN  ·  The research editor with a real agent inside

ZETEYN

The research editor where the agent does the work.

What Zeteyn Is

Automated research tools give you no fine-tuning panel. You run them and hope: every pass is a fresh roll of the dice, you cannot revise a single paragraph without regenerating the whole draft, and the process stays a black box you could never explain to a committee. In a codebase that trade is fine. In a dissertation you have to defend, an answer you cannot account for is worth nothing.

Zeteyn puts a full-grade agent inside your manuscript, in a glass box that keeps you in command. It edits paragraphs, runs discipline analysis, and drafts reviewer rebuttals. But nothing happens in the dark: every move is a visible change you can tune line by line, approve, audit, or roll back. You steer the small edits instead of re-rolling the whole draft, and you can always show how each change was made. That is why you can trust an agent with the work that actually matters.

The problems every researcher knows

You did not choose this work because it was easy. You chose it because it matters. These tools should not make it harder.

The old way

"I have 200 PDFs, 3 years of notes, and no idea which claim is still supported."

With Zeteyn

Every snippet you save is a hard-linked citation in a full literature library that lives on your own machine. Click any reference in your manuscript and the PDF opens to the exact sentence. Your evidence never gets lost, it gets organized.

The old way

"The AI hallucinated three citations in my introduction. I didn't notice until my supervisor did."

With Zeteyn

Zeteyn's AI operates only on your uploaded sources. It cannot fabricate citations it has not seen. Every suggested claim is traceable to a document in your vault.

The old way

"I told ChatGPT my research question. By message 15, it had no idea what my thesis was about."

With Zeteyn

Your Research Anchor (your core question, confirmed findings, and methodological constraints) is kept in the AI's view for the entire session, every session. It never forgets your project.

The old way

"I use one tool to write, another to manage citations, another to read PDFs, another to run analysis."

With Zeteyn

Writing, evidence, PDF reader, data analysis, molecule viewer, and journal formatting all live in one window, and your whole library syncs across local disk, cloud, and git. Your manuscript and your sources are always side by side.

Reviewer replies and self-critique have a home too: see Respond and Challenge in the workflow below.

An agent that does the work, not a chatbot that hands you a to-do list.

1
Agentic editing

The agent works inside your manuscript

"Other AI tools hand me text to copy-paste. I am still the one doing the work."

A full-grade agent edits your paragraphs, restructures sections, and runs analysis in side panels. It does the work; you stay in command.

2
Evidence Vault

Every claim traced to a real source

"The AI hallucinated three citations in my introduction. I didn't catch it; my supervisor did."

Drag a passage from any PDF onto your draft and it becomes a clickable citation that reopens the source at the exact sentence. Every citation the agent adds ties back to a source in your vault, and Zeteyn checks each one against OpenAlex, Crossref, and PubMed, flagging any it needs you to confirm with a visible underline. Search arXiv, PubMed, Semantic Scholar, OpenAlex, and Crossref and import straight into the vault, with open-access PDFs resolved automatically.

3
Hosted research agent · Plus & Pro

It builds your analysis, not just your prose

"I want an agent that actually runs things, not one that writes me instructions to run myself."

On Plus and Pro, a hosted agent runs in a secure sandbox: it builds analysis scripts, processes your data, and generates figures and tables, then reports back each step it took. Pull a git repository in, edit in the vault, and commit straight back. Runs are metered from your credit balance, every action logged.

4
Glass-box control

Every move is visible, every move reversible

"Letting an agent loose in my code is one thing. In my thesis? I need to see everything."

Every agent edit lands as a reviewable diff with a full audit trail. Each significant change is checkpointed, so one click rolls back both the manuscript and the conversation to a clean state.

5
Pre-submission check

Catch what Reviewer 2 will catch, first

"I didn't notice my discussion contradicted Chapter 2 until it was far too late."

One pass before you submit: citations verified against their sources, internal contradictions flagged, logic gaps found, journal format checked. Work the fix-list and clear it to green. No setup required.

6
Discipline skills

Field-aware workbenches, inside the document

"A generic agent does not know a Western blot from a Bayesian prior, or how to run my data."

One workbench for many fields: view 2D and 3D molecular structures pulled live from PubChem and PDB, run FFT and spectrogram analysis on your data, geocode and map places, view DICOM medical images, extract a knowledge graph from your sources, and code qualitative interviews with inter-coder reliability, all inside your manuscript, with skills spanning data science, chemistry, medicine, law, and the social sciences. Results stay publication-quality in the final export.

7
Journal-ready export

One click to submission format

"I wrote the science, then lost a day to the template and the citation style."

Export a formatted, submission-ready manuscript in one click, citations rendered and structure mapped. Switch journal templates without reformatting. Export to PDF, Word, LaTeX, Beamer slides, PowerPoint, and posters.

8
Guided onboarding

Productive in fifteen minutes

"New tools drop me into an empty screen and expect me to figure it out."

A seven-step tour walks you through the document, chat, vault, citing, and export the first time you open Zeteyn. Skip it any time, restart it from the Help menu. No IDE experience needed.

9
Local-first & private

Your manuscript never has to leave your machine

"My data is under an NDA. I cannot paste it into someone else's cloud."

Run an open model on your own hardware, and search your library with a bundled on-device embedding model: no cloud, no API key, fully offline. Your manuscript and sources stay on your disk or in your own git repository, off any vendor's servers.

10
Custom skills

Teach it your lab, journal, and method

"Every generic agent forgets my field's conventions and my supervisor's style."

Turn any chat into a reusable skill that captures your journal format, lab protocol, or review style. Keep it private, or publish it to the skill marketplace and earn credits when other researchers use it. A built-in browser, web clipper, PDF annotator, and Zotero import keep every source one step away.

From first idea to final submission.

Every mode has a purpose. Together they cover the full arc of academic writing.

01
Brainstorm Mode
Develop ideas, build your evidence base.

You have raw notes, half-formed hypotheses, and a pile of PDFs. The AI asks questions, surfaces connections, and suggests which ideas are worth pursuing. When something is worth keeping, save it to your Thought Log or Evidence Vault with one click.

02
Edit Mode
Refine your manuscript, with full control.

The AI reads your current draft before every suggestion. It never works from memory or a stale version. Every proposed change appears as a diff you must approve. You can accept, reject, or adjust each one. Nothing changes without your confirmation.

03
Respond Mode
Turn reviewer feedback into a checklist.

Drop reviewer or supervisor feedback in any form (PDF, screenshot, pasted email). Zeteyn extracts each comment, maps it to the right section of your manuscript, suggests a specific revision, and drafts your Response Letter as you work through the list item by item. Clear each to green when resolved.

04
Challenge Mode
Stress-test your own arguments.

Switch to Challenge and ask Zeteyn to read your work as a hostile peer reviewer. It audits every numerical claim, cross-checks your citations against what the cited papers actually say, constructs counterarguments, and rates each issue Fatal, Major, or Minor. You decide what gets fixed and what gets defended.

05
Peer Review Mode
Generate formal journal-standard reviews.

Load an external paper and produce a structured peer review report. Zeteyn analyzes the manuscript, identifies strengths and weaknesses, rates severity of issues, and generates a recommendation (Accept, Minor Revision, Major Revision, Reject). Ready to export as PDF for journal submission.

Web and desktop

Early access Early access build. The desktop apps are new and improve fast. Try one and send feedback anytime; it shapes what ships next.

First launch on desktop takes one extra click

Your system asks you to confirm the first launch while these early builds finish code-signing. Windows: click More info, then Run anyway. macOS: right-click the app, then choose Open. Linux: run chmod +x on the AppImage, then open it.

Windows

Microsoft Defender SmartScreen may show Windows protected your PC while early builds finish code-signing. It is a publisher check, and these steps clear it.

  1. In the browser download menu, click Keep.
  2. If the blue SmartScreen window opens, click More info.
  3. Click Run anyway, then continue the installer.
Browser download menu Keep button Microsoft Defender SmartScreen Run anyway button
macOS

The macOS build targets Apple Silicon (M1 and later). Gatekeeper asks you to confirm the first launch, and a right-click open approves it once.

  1. Open Zeteyn-0.1.6-arm64.dmg and drag Zeteyn to Applications.
  2. In Applications, right-click Zeteyn and choose Open.
  3. In the dialog, click Open to confirm.
  4. On newer macOS, if the app stays closed, go to System Settings, then Privacy & Security, and click Open Anyway.
Linux

The AppImage runs on most distributions once the file is marked executable.

  1. Make the file executable: chmod +x Zeteyn-0.1.6.AppImage
  2. Run it: ./Zeteyn-0.1.6.AppImage
  3. On a minimal system, install FUSE first so the AppImage can mount.

Why download instead of using the web app? The desktop version runs a local AI model entirely on your own hardware. Your files never touch a server. Useful if you work in a high-security environment, need to draft offline, or want AI suggestions without network latency.

Four zones, one interface.

Zeteyn packs a lot on screen. It stays simple once you know what each column is for. Open a source and the right tool appears, with no modes to pick.

Zeteyn four-zone workspace: sources on the left, editor in the center, viewer for reading, assistant on the right
Left · What you have

Vault & structure

The Evidence Vault holds every source (data files, evidence, documents) in one tree. The Module Tree is your manuscript's outline, with inserted data artifacts as leaves.

Center · What you do

Editor & Data

Write your manuscript in the Editor. Open a data source in Data to actually process it (run code, analyse, plot), then update the file or turn the result into an artifact.

Viewer · What you look at

Read-only reference

Documents and evidence (PDF, DOCX, images) open here to read, not edit. Data artifacts you produce also preview here, updating live as you process.

Right · What helps you

The assist rail

Chat with the agent, Review your draft (gaps, citations, lint), find Inspiration, set Layout, manage Citations, and reach discipline tools under Extensions.

The core loop: click a data source on the left → process it in the center → see the artifact in the viewer → insert it into your manuscript. When the data changes, the artifact re-syncs everywhere.

Frequently asked questions.

Is Zeteyn just another ChatGPT wrapper for academics?
No, and the difference is structural. Chat tools like ChatGPT or Perplexity treat each conversation as an isolated session. They have no knowledge of your manuscript, your sources, or what you concluded last week. Zeteyn is a persistent research environment. Your evidence vault, your thought log, your research anchor, and your manuscript are all in view for the AI at all times. It is not a chat tool marketed to researchers. It is a writing environment with a built-in AI that understands your project and changes its behaviour depending on whether you need to brainstorm, edit, respond to a reviewer, challenge your own argument, or produce a formal peer review report.
Will the AI change my writing without asking?
Never. Every AI suggestion appears as a visible diff, with additions in one color and deletions in another. Nothing is applied to your manuscript until you click Accept on that specific change. You can approve some suggestions and reject others from the same AI response. The AI does not have write access to your manuscript; you do.
How does Zeteyn prevent hallucinated citations?
Zeteyn's AI is grounded in your Evidence Vault (the PDFs, snippets, and sources you have uploaded). Every citation ties back to a document in your vault, and one click reopens the original paragraph so you can confirm it yourself. Zeteyn verifies each reference against OpenAlex, Crossref, and PubMed, and marks any citation it needs you to confirm with a visible underline, so you always see which claims stand on a source you provided.
Can I import my existing Zotero or Mendeley library?
Yes. Connect your Zotero account in Settings and your full library syncs into the Evidence Vault, including your annotations. If you use Mendeley or another reference manager, you can export a .bib file and import it directly. Zeteyn indexes every citation automatically. You do not need to start from scratch.
My institution has strict data policies. Is my research data safe?
Desktop version: Your files never leave your machine. The local AI model runs entirely on your hardware. There is no cloud sync unless you enable it. This is the option most suitable for sensitive research data, unpublished results, or high-security environments.

Web version: Files are stored in your private Vault, encrypted in transit and at rest. We do not use your content to train AI models. You can review our full data processing terms in the Data Processing Addendum linked in the footer.
I have never used a tool like this. How long does it take to learn?
Most researchers are productive within 15 minutes. You do not need any programming experience or familiarity with IDEs. The Manual walks you through five concrete steps: upload a PDF, save a snippet, write a sentence, ask a question, and export. Every feature is also accessible by just talking to the AI. You can describe what you want to do and it will do it, then show you where to find that action yourself next time.
Can I use Codex I already have on my computer?
Yes. For your own machine, sign in with the Codex CLI, start the home runner, then Zeteyn detects that runner before enabling the local Codex fuel. Zeteyn does not fake or store your Codex OAuth in the web app. For the ready-to-go hosted sandbox, Zeteyn uses platform-managed model credentials in the cloud runner. BYOK also works with OpenAI, Anthropic, Google, DeepSeek, OpenRouter, Groq, Together, Fireworks, DeepInfra, Mistral, xAI, Cerebras, Cohere, Hugging Face, Baseten, and local OpenAI-compatible endpoints.
What happens to my work if I stop paying?
Everything stays yours. Your manuscript, evidence vault, thought logs, and all settings remain on your machine (desktop) or can be exported before you cancel (web). You can export to Word, PDF, or LaTeX at any time, on any plan, including free. We do not hold your work hostage.
Who owns the copyright of work I write in Zeteyn?
You do, fully. Every change requires your explicit approval, which means every sentence in the final manuscript is one you chose to include. Zeteyn does not claim any rights over content created using the tool. For AI-assisted writing disclosure requirements at your institution, we recommend checking your specific policy. The relevant fact is that you reviewed and approved each suggestion.
How is this different from Overleaf, Notion, or Obsidian?
Overleaf is a collaborative LaTeX editor. Excellent for typesetting, not built for the writing and reasoning process. It has no evidence vault, no AI modes, and no adversarial argument checking.

Notion is a notes and project management tool. It does not understand academic argument structure, citation linking, or manuscript submission requirements.

Obsidian is a personal knowledge base. Powerful for notes, not designed for producing a publication-ready manuscript with source-grounded claims.

Zeteyn is designed specifically for the process of writing a research paper: from first reading to final submission, with five AI modes that cover brainstorming, editing, responding to reviewers, stress-testing your own arguments, and producing formal peer review reports.
How is Zeteyn different from Claude Science?
Claude Science is Anthropic's bet on automated research: a workbench where agents connect to 60+ databases, run your data, and produce reproducible results. For the work that runs (experiments, data pipelines, protein structure), it is genuinely powerful, and worth using.

But automation has a boundary: what you can automate is what you can compute. The moment the work turns to theory, to argument, to the places where you have to think through why one step earns the next, autopilot is the wrong tool, not because a model cannot write it, but because this is work you have to keep your hands on. That holds for the humanities as much as for the theory half of any science.

Zeteyn takes the other road: you stay in the loop. Every edit the AI makes to your manuscript is a proposal you accept or reject. Your argument is built from modules you can expand as deep as you want and collapse back. Any step you dislike rolls back in one click, like Ctrl+Z with a longer memory than yours. Citations can only come from your own vault, so it cannot invent a sentence that merely sounds right.

It does not think for you. It lays your thinking out, keeps it in order, and lets you take any of it back.

And the conveniences are there: it runs in your browser on any OS and installs as a desktop app on Windows, and the model is yours (Claude, Codex, DeepSeek, or a local one), including bringing a second model in to review the first, instead of the same model grading its own homework.
Can I collaborate with my supervisor or co-authors?
Supervisor feedback is a first-class workflow in Respond mode: paste, type, or photograph their comments and Zeteyn maps each one to the relevant section of your manuscript, suggests a specific revision, and drafts a response for each point. Real-time co-authoring is built in on paid plans (Plus and Pro): co-authors edit the same manuscript together with live presence, owner, editor, and viewer roles, and collaborative rollback that returns any shared change to a clean state. On the Free plan, invited collaborators have view access. You can also export to Word for tracked-changes collaboration the traditional way.
Does it support math, chemistry, and scientific diagrams?
Yes. Type /tikz for diagrams and /code for a code cell; molecular structures (2D and 3D), maps, DICOM images, and other discipline tools open from the panel rail. Equations render inline with standard LaTeX syntax, and figures are rendered so they look the same in your exported PDF as in the editor.
I switched AI tools before and lost everything. What makes this different?
Your files are stored in standard formats (Markdown, PDF, BibTeX). You can export at any time to Word, PDF, or LaTeX, with no proprietary format lock-in. The desktop app stores everything locally. If you close your account, nothing is deleted until you delete it. We also keep checkpoint history so you can roll back to any prior version of your manuscript, separate from any cloud backup.
