Download FAQ

Is my data sent to the cloud?
Never. All memory — sessions, facts, code snippets, notes — is stored in a local SQLite database at ~/arcbrain/data/memory.db. Nothing leaves your machine unless you explicitly choose a cloud AI provider.
How do I update ArcBrain later?
Open the Setup GUI at localhost:9876 and click Check for updates. It runs git pull and pip install -r requirements.txt. Your memory database is never touched by updates.
Do I need a license to use ArcBrain?
No. The Community edition is free forever and includes local memory storage, all AI editors, and unlimited sessions. Pro adds scheduled backups, memory export/import, and priority support.
Can I use it without Ollama?
Yes. The memory features work without any AI model. Ollama (or OpenAI/Claude/Gemini/Grok) is only used for end-of-session summarization, which is optional.
What editors are supported?
VS Code (GitHub Copilot), Cursor, Claude Desktop, Windsurf, and Claude Code CLI. The Setup GUI connects all of them with one click.
Can I uninstall it completely?
Yes. Delete the ~/arcbrain folder and remove the MCP config entries from your editors (the GUI has a one-click Disconnect button for each). Nothing else is installed system-wide.
