Trillion vs Heptabase
A visual notes app with whiteboards and cards for research and learning.
Every AI you use, working on the same things
- Bring your own AI. ChatGPT, Claude, Codex, Gemini or any AI you connect reads and adds to the same decisions, files, lists and people.
- Work you can follow. Each job shows who asked, which AI took it, and what is moving, finished or stuck.
- Hand it on. One AI can pass a job to another, and the next one starts from what the first one kept.
Decisions kept with their reasons
- One question at a time. Your AI walks a hard choice through the questions that matter, then you choose.
- Kept with the why. Each decision keeps its options, its reasons, its next step and how you will know it worked.
- Lists for anything. A CRM, a pipeline or any table, sorted, filtered and kept up to date by the AI you use.
Shared spaces for the people you work with
- One place per pursuit. Messages, files and decisions for a project sit together, and everyone in it sees the same thing.
- Their AIs too. Each person brings their own AI into the space, and the AIs work from the same record.
- Share a link. Send one file, one list row or a whole space, and stop sharing whenever you want.
