A unified workspace and harness for researchers.

LaTeX from handwriting

Write by hand on a tablet with a pen. Each block is read and written into the .tex file beside it, and the PDF rebuilds. Edit either side — a paragraph typed in the editor comes back to the page, and ink comes back as LaTeX.

A LaTeX source with a section, an equation and a figure, beside the compiled PDF showing the same three.
On the desktop — the .tex the page was written into, and its PDF.
A handwritten heading and the Euler-Lagrange equation in a hand-drawn box, above a plot produced by a Python cell.
On the tablet — the same page, written by hand.

Papers and references

Search arXiv, OpenAlex, Crossref, Europe PMC and INSPIRE at once and download into the project. Every paper becomes a citable entry with a stable key; import .bib or .ris, and \cite{} completes from your own library.

A downloaded paper open in the app, its numbered equations set as the publisher typeset them.

A research agent that reads what you are reading

Ask about the paper open beside you. Derivations run through a computer algebra system a step at a time, and every equation in the answer is marked with where it came from — derived, quoted from a paper, or merely stated.

A paper on the left and the assistant's derivation on the right, each display equation carrying its own number.

LaTeX, with the PDF beside it

Completion that knows your own labels, packages and .bib keys. Every compile error is one click from the line that caused it, and a figure path is fixed before the engine ever sees it.

A .tex source on the left and its compiled PDF on the right, with a word and equation count along the bottom.

Code that runs where you wrote it

Python with a language server, checking and formatting. Run the whole file, one cell, or just the selection — variables carry over between runs, and figures come back beside the code.

Interactive notebooks

marimo notebooks in the same window. Move a slider and everything that depends on it re-runs. Nothing runs until you run it — opening a notebook executes nothing.

A marimo notebook with sliders for the simulation parameters above the plots that depend on them.

A browser in the workspace

A journal portal, a docs page or a paper on the web, in a tab beside your work — and the assistant can drive it when you ask, on hosts you allow.

A web page open in a tab of the app, beside the rest of the work.

Stupidon Notebook

Write by hand on a tablet. It compiles to LaTeX on your desktop.

Opens from the app by QR code. Nothing to install.

  1. In the desktop app, choose Sync Tablet.
  2. Scan the QR code with your tablet or phone.
  3. The notebook opens in the browser, paired with your computer.

An Android app is coming. You don't need it — the browser is enough.

All of it

Your models
Gemini, Claude, OpenAI, or a local model through Ollama. Your key, your bill.
Your files
Everything stays on your disk. What the assistant runs is confined to the project folder and has no network by default.
Closed beta
Testers are let in by hand, in waves, and get credits for the assistant. Join the waiting list to be one.
