Polleo builds AI-first software for people who already think for a living. Our first product is Gryphon — it brings AI to your Obsidian vault with guardrails at runtime, so you can put Claude inside your second brain without lowering the bar on the operations that matter.
Bring AI to your vault — with guardrails at runtime.
Claude lives inside your Obsidian vault, reading and editing your notes directly. Built around a two-dimensional security model: convenience and guardrail are independent, so turning auto-approve up never silences destructive commands or web-fetches that deposit untrusted content into your vault.

The obvious question in 2026 isn't whether your software uses AI. It's whether it was designed assuming AI existed from day one, or retrofitted onto a workflow that predates it. We only build the former.
We don't train on your content. We don't route your notes through our servers. AI-first is not the same as cloud-first — the best place for your second brain is still on your machine, and the best place for your API keys is still in your hands.
We're agile: real solutions, shipped fast to real users. What sets us apart is a deep security-first mindset — hard-earned experience baked into every AI-driven product we build, so we can solve the problems people actually face without ever asking them to lower their guard.
