What is it?

This is a document editor that runs in the browser. It opens, edits, converts and saves Word, Excel and PowerPoint files, and can annotate, fill and export PDFs. Core document processing happens on the user's device, so no account or Office installation is required.

It is built on the ONLYOFFICE editors, with a WASM converter handling format conversion. Users can write changes back to their chosen file where supported, or download an export. Recent work is kept in the browser for recovery for seven days.

An optional, experimental AI assistant can draft text, work with spreadsheet data, create slides and answer questions about the current PDF page, with changes reviewable before they are applied. The editor can also be installed as a PWA, self-hosted as a static site, run via Docker, or embedded in other apps through an iframe API.
