What is ThinkEx?

ThinkEx is a visual thinking environment where you spread out your sources — PDFs, YouTube videos, audio files, websites, and notes — on a canvas, then work alongside AI that can see exactly what you point it to. Unlike chat-first AI tools, ThinkEx keeps your knowledge organized and persistent. Insights you extract become cards that stay in your workspace. Context never resets.
1

Create a workspace

Start a new workspace from the dashboard. Choose a blank canvas or a template with sample content already in place.
2

Add your sources

Upload PDFs, paste YouTube links, add websites, or write notes directly. Each source becomes a card on your canvas.
3

Select context and ask

Click to select the cards you want the AI to reason over, then ask your question. The AI works only with what you’ve chosen.
4

Capture insights

Save AI responses as knowledge cards — notes, flashcards, or quizzes — that persist in your workspace for future sessions.
