AI edits the rest.

Free to install · No credit card · Works on Chrome, Edge, Brave

What makes it different

A screen recorder that understands your screen

Most recorders capture pixels. Screencast captures meaning — every click, input, and focus event — so our AI can edit like a real director.

🎬

AI Director

Gemini-powered AI analyzes your voice, events, and screen content to decide where to cut, zoom, and pan. Cinematic output, zero editing.

🔍

DOM-Aware Zoom

Unlike Loom, we know what you clicked. The AI zooms into the exact button, field, or element — not just your mouse cursor.

📺

4K Capture

Up to 1920×1080 @ 30fps with adaptive VP9/VP8 encoding. Crystal-clear output, optimized for streaming and export.

🎤

Multi-Track Audio

Mic + tab audio, mixed with precise Web Audio API timing. Built-in echo cancellation and noise suppression.

📸

Camera Bubble

Floating webcam overlay — circular or rectangular, draggable, resizable. Record Screen + Camera or Camera Only.

⌨️

Typing Overlay

Every keystroke and form input appears as an elegant glassmorphism caption on the video — automatically.

🔊

Automatic SFX

Whooshes on zooms, clicks on interactions, transitions on cuts. Pro-grade sound design, done by AI.

🌍

Multilingual Dubbing

Translate and dub your screencast into 30+ languages with AI lip-sync. One recording, global reach.

One-Click Share

Direct S3 upload, instant shareable link. No downloading, no uploading — just hit stop and send.

🎯

Three Capture Modes

Full Screen, Current Tab, or Camera Only. Pick the right mode for tutorials, demos, or quick async updates.

📦

Events Export

Download the raw video + events.json + HTML snapshots as a ZIP bundle. Pipe into your own workflow.

🧠

Context-Aware Highlights

The AI understands what's worth highlighting — form fields being filled, errors, results — and frames them beautifully.

FAQ

Questions, answered

How does the AI editing actually work?

Screencast records three streams: your voice, your screen, and every DOM event (clicks, inputs, focuses, scrolls). Our AI director — powered by Gemini — analyzes all three to figure out what matters. It cuts pauses, zooms into the exact element you interacted with, adds typing overlays when you fill forms, and drops in SFX at the right beat. The result is a cinematic video that looks hand-edited.

What's "DOM-aware" recording and why does it matter?

Traditional recorders see pixels. Screencast sees the page — buttons, inputs, elements — because it runs inside Chrome. When you click a "Submit" button, we know it was that button, not just "the pixels under the cursor." The AI uses this to zoom precisely, highlight the right thing, and generate captions that actually match what's happening.

Do I need to install a desktop app?

No. Screencast is a Chrome extension — install in one click, start recording in the next. Works on Chrome, Chromium, Edge, and Brave. No admin rights, no installers, no friction.

Can I record the whole screen or just a tab?

Both. Three modes: Current Tab (clean, fast, best for web demos), Full Screen (native Chrome picker — any window or display), and Camera Only (async updates, talking-head videos).

Is there a free plan?

Yes. The extension is free forever for recording. AI auto-editing and multilingual dubbing are metered — new users get free credits to try everything. No credit card required to start.

What about privacy?

Recordings are yours. Videos upload to your private CDN link — unlisted by default. DOM events never leave your browser unless you choose server-side AI rendering. You can export everything as a local ZIP and keep it offline.

Can I dub my videos into other languages?

Yes — 30+ languages with AI lip-sync. Record once in English, ship localized versions for every market. Works for tutorials, product demos, and support videos.
