The AI workspace where teams and agents get work done together
Combine docs, wikis, projects, and databases into one structured system of record that stays linked as your content grows.
Draft, summarize, translate, and answer questions inline, or build custom agents that automate recurring workflows around the clock.
Find answers instantly across Notion and connected apps, with citations so you can verify where each answer came from.
Use relations, rollups, views, and a large template gallery to model anything from a CRM to a content calendar.

One key for 4,100+ agent tools, pay per call
A single treg token routes to 4,100+ endpoints across 127 providers, so no per-provider signups or scattered key files.
See each provider's price plus measured success rate, speed, and last-answer time, and pin a preferred vendor when you want.
Pay fractions of a cent per call with the price shown before you commit, no monthly seats required.
Route calls through your existing provider keys at no markup; credentials are injected server-side and never stored on a machine.
