What is the main difference between Bito and Pi?

Bito provides a system-wide knowledge graph for multi-repo context, integrating with coding agents (Cursor, Claude Code) and project tools (Jira, Slack). Pi is a minimal, extensible terminal harness that gives developers control over providers, prompts, and session history.

Can I use Pi with multiple AI providers?

Yes, Pi supports 15+ providers and hundreds of models, allowing mid-session switching via /model command or keybindings.

Does Bito support on-prem deployment?

Yes, Bito offers on-prem deployment with SOC 2 compliance for enterprise customers.
