Why Lattice
A paper is more than a .tex file: it is the PDF you check, the papers you cite, the comments your co-authors leave and, now, an agent that edits with you.
Lattice keeps all of them in one native Mac window.
Your project stays an ordinary folder on disk, so it works offline, opens in any other editor and fits under Git; Overleaf is a sync target, not the place your paper lives.
Write
Source and PDF side by side (or the PDF in a window of its own, for a second screen), with completion and diagnostics as you type, SyncTeX jumps both ways and one-click builds with your own TeX Live.
Switch a .tex tab from Source to Visual to read and edit it with its headings, emphasis, equations, lists and figures drawn in place, in the same editor.
An outline rail follows your sections, \cite keys show their reference on hover, and six highlighters with meanings mark what still needs work.
Start from a NeurIPS, ICML, ICLR, ACL, CVPR or AAAI template or one of two thesis classes, and Export for arXiv writes one ZIP that builds on its own.
Dock any panel anywhere, keep Writing, Reading and Bibliography layouts, or save your own workspaces.
Revise
Select text to Proofread or Polish it in place, with a reason for each edit.
Annotate the source or the PDF, then revise from your annotations in rounds: the agent proposes an edit for each one and you accept or reject it in place.
Annotations and Overleaf comments also line up in a column beside the PDF, each level with its mark on the page, where you read, reply to and resolve them.
Export review PDF writes the annotations you tick into a copy of the compiled PDF as standard PDF comments, so collaborators can read them in Preview, Acrobat or Zotero.
Bring your own agent
The Agent panel runs Claude Code or Codex, or another agent CLI on your Mac such as Cursor, OpenCode or Droid, signed in as you.
Or connect your own OpenAI- or Anthropic-compatible API in Settings › Agent › Model endpoint: an address, a key (kept in your Keychain) and model names, which the agent runs through Pi with no command-line tool to install.
Lattice comes with no model and no AI subscription of its own.
The agent reads your project and papers, fixes build errors and edits files; every change shows as a diff you can review or undo.
It can also use the MCP servers you add to that CLI, such as Zotero or Heptabase: see Zotero, Heptabase and the Agent panel.
Research
Paper shown: Albert Gu and Tri Dao, “Mamba: Linear-Time Sequence Modeling with Selective State Spaces”, arXiv:2312.00752, CC BY 4.0.
Add papers by arXiv ID, DOI, title, link or BibTeX, or straight from your Zotero library, and read each as a blog, the paper or the PDF beside your draft.
Cite in one step, with the reference on hover.
The library sorts, filters and groups by what you cite; Check references audits your bibliography against Crossref and shows each finding in a keyboard queue.
Collaborate with Overleaf
Two-way Overleaf sync with live presence, chat, comments and tracked changes.
Your co-authors stay on Overleaf and their edits arrive as they type; nobody else needs Lattice.
Comments read as conversations with one colour per person, and margin review sets comments and suggestions beside their lines.
Every format
Markdown notes edited in blocks, tldraw whiteboards, interactive HTML pages and spreadsheets with formulas live in the same project as the paper.
Slides are React decks powered by Open Slide: edit them, comment on them, let the agent revise them, and present from Lattice.
Import files… brings in anything else from your Mac.
History
One timeline for saved versions, every edit from you or the agent, and Overleaf's history.
Open any entry to see its diff and restore a file, or Compare… any two versions and export the PDF with the changes marked (via latexdiff from your TeX Live).
Track changes turns on review mode: your edits since then are marked in the source as you type, the PDF can show them marked too, and you accept or reject each change, or all at once, without an Overleaf plan.
The Git panel shows changes and pull requests when the project is a repository.
Install
Lattice runs on Macs with macOS 14 or later, Apple silicon or Intel, and builds with your own MacTeX or TeX Live.
No TeX yet? Lattice offers to install BasicTeX for you: it is the first step of the Get started checklist, and a build that finds no TeX offers it too.
