What Heptabase does in ChatGPT
The Heptabase plugin connects ChatGPT to your Heptabase knowledge base. It can search and read the things you keep there, including cards, journals, PDFs, tags, databases and whiteboards. That makes it easy to ask for a summary of what you have written on a topic without digging through the app yourself.
It can also write back. You can create a new card from the current conversation, edit existing notes and change properties such as a card's status. Selected cards can be opened in an interactive reader inside the chat, so you can look at a note in full while you talk about it.
For visual thinkers, it can place existing cards and other objects onto your whiteboards. The listing describes placing objects you already have, so build the card first and then ask for it to be added to the board you want.
