Nook

Nook takes a screen recording you already have, from QuickTime, Zoom, OBS or Loom, and turns it into two things: a polished, narrated demo video and a written step-by-step guide. It writes the script, adds an AI voiceover or cleans up your own narration, captions it, and blurs emails, card numbers and API keys. The video ships as a share page, an embed or an MP4, and the guide exports to PDF, Word or Markdown.

Founders, app developers submitting for Shopify or Meta review, agencies doing client handovers, and support teams all need the same walkthrough twice, once as a video and once as docs, and making either by hand takes hours of re-recording and editing. Nook had to work from a rough recording with no recorder or extension to install, and it had to be safe to share without someone checking every frame for leaked data.

A single upload drives the whole pipeline. Nook reads the recording to understand each step, writes the script and the guide from it, generates the voiceover and captions, and finds the sensitive regions to blur before anything is rendered. Long jobs run in the background, so a 15-minute recording never ties up the browser, and branding with logos, colours and intro and outro cards is applied at render time.

Live at usenook.live. The first video is free, then it is $9 per video, or a subscription at $19/month for 10 videos or $49/month for 30, with no per-seat pricing. One upload of up to 15 minutes produces both the demo and the documentation.
