Show HN: Tech docs → video explainers in seconds

https://symvol.io/
2•feliks22•7h ago
What it is Symvol turns any tech doc into AI-narrated video in ~1 min. Every code block stays live-viewers can click-to-copy and run snippets while they watch.

Why we built it We began as a generic “text → video lesson” tool. Early testers asked for coding support, so we added a code-aware pipeline. This is the first public launch of that version.

Try it Drag-drop a PDF at symvol.io (free to try) OR install our Chrome extension to run Symvol on any web page

Looking for feedback on 1) Narration accuracy 2) Clarity of visuals 3) Usefulness of the live copy-code feature

We’ll be around all day - happy to answer questions or dive deeper in the comments!
