What Unabyss does

Unabyss is your personal context layer for AI. Connect the apps you already use — LinkedIn, your website, Notion, Gmail, Slack, GitHub — and Unabyss extracts, structures, and keeps your context up to date automatically. Then any AI tool you use, including ChatGPT, can pull exactly the right context when you need it.

No more re-explaining your role, your projects, your tone, or your company at the start of every conversation. Your context lives in one place, stays current as your sources change, and travels with you across every AI tool you use.

What you get:

Auto-extraction from your existing tools in under 90 seconds Structured context files you fully own — persona, voice, company, and more Granular permissions: share your writing voice without exposing professional details One-click exports for investor updates, meeting prep, bios, and ICPs Always up to date as your connected sources sync

Built for founders, operators, and builders who live across multiple AI tools and are tired of starting from zero every time. If you've ever thought "ChatGPT should already know this" — that's what Unabyss fixes.
