About Glassbrain

Our story

We built Glassbrain because we experienced the pain of debugging AI applications firsthand. When an AI gives a wrong answer, the typical workflow is: check logs, add print statements, guess what went wrong, redeploy, and hope for the best. We knew there had to be a better way.

Glassbrain captures every step of your AI's reasoning - from user input through retrieval, LLM calls, and tool use to final output. When something goes wrong, you see exactly where and why. Click any node, swap inputs, replay, and verify the fix. No redeployment needed.

We are building the debugging tool we wished existed when we were building AI products.
