OpenYak – An open-source Cowork that runs any model and owns your filesystem

Your local AI agent — private, powerful, personal.

OpenYak is an open-source desktop AI assistant that runs entirely on your machine.

Manage files, analyze data, draft documents, and automate office workflows — all without uploading anything to the cloud.

Office Automation — Batch rename, sort, and clean up files across folders with auditable change logs. No more manual filing.

Data Analysis — Parse spreadsheets, CSVs, and documents locally. Spot anomalies, track trends, and export decision-ready reports — without uploading a single file.

Content & Writing — Turn rough notes into polished documents. Draft memos, policy updates, and professional communications in a consistent company tone.

Team Operations — Merge notes from PDFs, DOCX, and CSVs into structured briefings. Auto-extract action items, assign owners, and track deadlines.

IM Integration — Connect 8+ messaging platforms — WhatsApp, Discord, Telegram, Slack, Feishu, Signal, iMessage — through OpenClaw. Let your AI assistant receive and reply to messages across all your channels from one place.

Automations — Schedule recurring tasks with cron-based triggers. Daily data digests, weekly reports, automated file cleanup — set it once and let Yak handle it.
