Guace
Turn local files into an AI-native knowledge base
Guace is a local-first personal knowledge base for macOS. Browse notes, PDFs, webpages, images, and code; ask questions with source context; save useful answers back to ordinary files; and delegate heavier follow-up work to Claude Code or Codex when needed.
Hey Product Hunt — I’m Lest, the solo maker of Guace.
My knowledge is spread across Markdown notes, PDFs, saved webpages, images, and code. AI chats can answer questions, but useful results often remain trapped in conversations. Agent tools can execute work, but their outputs often live somewhere disconnected from my long-term knowledge.
I built Guace as a local-first, AI-native personal knowledge base for macOS:
• Point it at ordinary folders instead of migrating into a proprietary workspace
• Ask across files while keeping the source visible
• Save useful conclusions back into files you own
• When needed, delegate follow-up work to Claude Code or Codex in isolated workspaces
Guace is currently a free public beta and uses your own model provider. Managed agents are optional — the knowledge-base workflow works without them.
If you try Guace, honest and specific feedback would be incredibly helpful — especially about onboarding, usability, and bugs.
I’d especially love feedback on three things:
1. How smooth was it to get from installation to your first useful result?
2. What felt confusing, awkward, or unnecessarily complicated?
3. What bugs or missing features would stop you from using Guace regularly?
