Show HN: Revisit – Session recording analysis that "watches" the video

https://revisit.pro/
2•egykettoharo•8h ago
Hello HN, I’m the creator of Revisit (https://revisit.pro), a session recording and analytics platform.

We built this because existing tools (FullStory, Smartlook) force you to manually watch thousands of user sessions to find one bug. We wanted an AI that could watch the sessions for us and just tell us why users are churning.

The "AI" Architecture - Store Events: We record DOM events, console logs, network requests, and assets using a lightweight script. - Replay & Render: On the backend, we spin up a headless browser (Puppeteer) to replay the session exactly as the user saw it. - Video Generation: We convert that replay into a physical video file. - Visual Analysis: We send that actual video file to Gemini

This allows the AI to "see" the session like a human does. It can detect visual glitches, rage clicks, and confusing layouts that code-based analysis might miss.

Project-Wide Chat - Beyond single-session analysis, we built a project-wide chat assistant.

Contextual Answers: The AI retrieves the most relevant sessions, "watches" the key moments, and writes an answer backed by video evidence.

Features - Deep Context: We capture everything—console logs, network payloads, and assets—so you can debug issues without asking users for screenshots. - Unlimited Seats: We don't charge per seat. Bring your whole team. - Privacy First: Built-in masking for sensitive data before it leaves the user's browser. - And much more.

We are currently open for signups and would love feedback on the analysis quality!
