Crafted with AI

Major edits, automated

AI does the heavy lifting. The final touches are all yours — everything is customizable.

Perfect Video Scripts

AI transcribes your audio, removes filler words, and rewrites your script clearly and concisely — perfectly matching your intended message.

Lifelike AI Voiceovers

Your recorded audio is swapped with AI voiceovers that sound impressively professional and realistic. Multiple voices and languages available.

Smart Interaction Anchors

Narration is automatically synced to your clicks and keystrokes. Edit the text without breaking audio-video sync — AI keeps everything aligned.

Auto-Generated Documentation

Clear, step-by-step articles with screenshots — created automatically from the same recording. Publish to your help center or knowledge base.

Branded Slides

Custom intro and outro with your logo, colors, and text. Keep your videos consistently on-brand without a design team.

Variable-Speed Compilation

AI adjusts video pacing so narration and actions stay perfectly aligned. No manual trimming — the final video flows naturally.

How It Works

Stunning content in just four steps

No complex software. No video editing. Record, let AI do the magic, and export.

01

Record Your Screen

Open Nexa on any website and hit record. Narrate as you go — no scripts or prep needed. Clicks and interactions are captured automatically.

02

AI Does the Magic

Nexa transcribes your audio, polishes the script, and generates a narration synced to your actions. Each interaction becomes a documented step.

03

Customize to Your Liking

Edit the narration, pick an AI voice, add branded slides. Review the auto-generated article. Every detail is fully editable.

04

Export & Share

Get a polished narrated video and a structured step-by-step article from the same recording. Download, embed, or publish.
