Download ArcBrain

Accepting 5 beta testers

The first 5 beta testers who give real feedback, bug reports, and product ideas will receive a free full ArcBrain Lifetime license.

What you get Free full lifetime access once you complete the beta and share useful feedback.

What we need Honest install notes, bugs you hit, rough edges, and new ideas that would make ArcBrain stronger.

Best fit People actively using VS Code, Cursor, Claude Desktop, or Windsurf who can test quickly and communicate clearly.

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?

All plans include a 14-day free trial with no credit card required. After the trial, choose Pro Monthly ($25/mo) or Pro Lifetime ($199) to continue. Your local memory data is always yours to keep regardless of plan status.

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.

How does ArcBrain compare to Cursor's built-in memory?

Cursor's memory relies on .cursor/rules files and system prompts that you write and maintain by hand — static, session-scoped, and siloed to one editor. ArcBrain automatically captures decisions, errors solved, configs applied, and project context across all your editors (VS Code Copilot, Cursor, Claude Desktop, Windsurf) in a single persistent knowledge base. Memories survive every conversation, are semantically searchable, and follow you across projects and machines.

Is this related to Giga Memory?

ArcBrain is the self-hosted evolution of the Gigaboost / Giga Memory concept — built by ARC Technologies. Instead of a $70/month cloud service, ArcBrain runs entirely on your own machine: local database, local vector search, optional local AI via Ollama. Same persistent-context idea, zero subscription lock-in, and your data never leaves your computer.
