Local AI Doc Assistant - Offline Natural Language Editing in Browser

Edit documents with natural language directly in browser using local small language models, no internet or API costs.

Users

Privacy-conscious writers, students, researchers, budget-limited teams.

MVP

Run OnlyOffice editor in browser; integrate WebLLM local model; support basic natural language commands (rewrite, summarize); offline capable; document export.

Revenue
