An Overleaf alternative with AI edits

• —Real-time editing with everyone on the paper, each person's cursor and selection where they left it.
• —pdfLaTeX, XeTeX and LuaTeX, with biber and latexmk, compiled on the server. Nothing to install.
• —A PDF preview beside the source, and Show in PDF to jump from a line of source to its place on the page.
• —Comments anchored to the sentence they were made against, so they survive everyone else's edits.
• —Share a project as an editor or a viewer. The server rejects a viewer's edits.

• —The AI model edits in place. Select a passage, press Proofread, and the revision lands in your file as a word-level diff. Commands, math, citation keys and labels come back as you wrote them. It runs on Claude Opus.
• —The assistant reads the whole project, so you can ask about a section three files away.
• —The engine is picked from your file — the magic comment, the packages, the fonts — unless you pin one.
• —A Sources panel lists every .bib entry with how often the draft cites it, and flags a citation with no entry before the build does.
• —A Plan panel marks each section empty, outline or drafted, and collects your TODO comments as open questions.
• —Two build modes: a fast single pass while you write, and a full run when the cross-references have to be right.

Download the project from Overleaf as a source .zip and drop it into the Files panel of a new sharewrit project. Folders, .bib files and figures come across as they are, and sharewrit picks the main file. Any project downloads again as a .zip at any time.
