Nexa — Product Videos and Documentation in Minutes, with AI

Turn raw screen recordings into narrated videos and step-by-step docs with AI — in minutes, right from your browser.

Living documentation for SaaS — video, article, help center, chatbot, and interactive guide from one recording. Your SaaS ships weekly. Your docs should too. But turning a screen recording into polished documentation takes hours — writing scripts, editing video, capturing screenshots, building help articles. Nexa does all of it from a single 2-minute screen capture. How it works: 1. Capture Open the extension on any page of your SaaS. Hit record, walk through the flow. Talk naturally — or stay silent and let AI narrate for you. Nexa tracks your clicks, typing, and navigation automatically. 2. Edit AI transcribes your audio, generates a clean script, captures screenshots at each step, and drafts a full article. The editor opens automatically — rewrite text, pick an AI voice, adjust timing, add branded slides. 3. Publish One click. Your narrated video, step-by-step article, help center widget, AI chatbot, and interactive guide go live. Embed anywhere with a single script tag. 5 outputs from 1 recording: - Narrated Video — Professional AI voiceover with animated cursor, branded intro/outro slides, and subtitles.
