A refined ChatGPT interface powered by your own API key
Connect your own OpenAI API key so you control model choice, spend and data flow rather than paying a bundled subscription.
Responses stream token by token, keeping long conversations responsive and easy to follow.
Save reusable prompts so repetitive tasks take one click instead of retyping the same instructions.
Dictate prompts by voice and bookmark the conversations or answers you want to return to.
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.
