stepvideo turns one screen recording into a finished tutorial — no editing. Record yourself doing the task once in Chrome. stepvideo watches what you actually did — every click, scroll, and page change — and cuts the video for you: it zooms in on the actions that matter, skips the dead time, adds an AI voiceover with word-by-word captions, and writes a step-by-step guide with annotated screenshots to match. WHAT YOU GET FROM ONE RECORDING • A polished tutorial video — automatic zooms on your clicks, smart cuts, AI narration in natural voices, word-accurate captions • A written how-to guide — numbered steps, annotated screenshots, ready to share or export • An editor built on steps, not timelines — rewrite a step's script and the voiceover, captions, and cuts update to match PRIVACY BUILT IN, NOT BOLTED ON • Records only when you press record — never in the background • Typed text is never captured — keystroke contents stay on your machine, password fields are excluded entirely • API keys and tokens visible on screen are redacted before upload • Email and password fields are flagged for automatic blur in the video and guide HOW IT WORKS 1. Click the extension and choose tab or screen recording 2. Do the task once, at your own pace — flubs are fine, they get cut 3. Open stepvideo.io: your video and guide are ready to edit, share, or export Made for product teams, support teams, and anyone who documents software: onboarding walkthroughs, help-center content, release notes, internal how-tos.
