Click the question box to explore
Explorer film
How far one question branches, and how Thinket holds on to every branch. Use the button on the right for sound.
It is the question the app asks when you open a new forest.


Thinket Explorer.Start from a question
The familiar way. Ask anything in the center, and move the follow-ups that surface while reading to the right sidebar.
Highlight a phrase in an answer and a question box opens right where you are. Follow-ups continue on the right; on the left, they grow into a tree.

Thinket Reader.Start from a documentNEW
Open a paper or a dense handout in the center, and highlight any passage the moment it puzzles you to ask right there.
Papers and lecture notes render in the center pane as they are. Highlight to ask on the spot, and every answer is written with the whole document as background.

Thinket Memo.Start from your notesNEW
Write your thinking as a hierarchy on a canvas. Bring a finished exploration here too, pick the branches you want, and turn them into one piece of writing.
When you are done exploring, lay the branches you choose on a canvas and turn them into one piece of writing. Questions become headings, answers become the body. Save it as Word.
Open the Memo demo →When you trade questions and answers with a conversational AI, a single reply can raise several new questions, and the chat stretches on without end.
Sooner or later a moment comes when it all blurs: what was I curious about at the start, what did I ask along the way, and what exactly did that answer say.
You try to scroll back up to retrace your steps, but the thread has grown so long that it is easy to give up.
I wondered: when a question arises from a passage, could you simply pick that spot and ask right there?
And further, if the record of questions and answers could be structured to fit in a single view, I believed information could be processed far more deeply.
So I built Thinket, a branching conversational AI. Drag the point you are curious about in the middle of a conversation to resolve it on the spot, and let it become a second brain that visualizes every trace of your exploration.
We do not make a promise we cannot keep: that simply using Thinket will improve your learning. AI produces fluent answers more easily than any brilliant human teacher, and inside Thinket that problem does not go away. It still threatens us.
What we believe we can do is create the conditions for not mistaking a fluent answer for understanding: to doubt, to go back, to branch off and ask, and to reconnect. Thinket does not think for you. It makes room for thinking to continue.
