Why Synapse

The intelligence layer between video and knowledge

Built for developers and learners who are tired of watching the same tutorial twice.

Contextual Understanding

Our AI doesn't just transcribe. It understands the narrative arc and organizes content intelligently.

Code-First Formatting

Automatic syntax detection and formatting for every code snippet mentioned in the video.

Notion Native

Uses official Notion block types — toggle blocks, code blocks, callouts. No copy-pasting.

Timestamped Notes

Every section links back to the exact moment in the video. Jump to context in one click.

Key Takeaways

AI extracts the top insights and concepts from any tutorial automatically.

No Lock-in

Your notes live in your Notion workspace. Export, share, or delete anytime. Your data, your rules.
