Everything you need to make a video — record, edit, caption, export

One browser-based studio that replaces a screen recorder, a timeline editor, and a template maker.

Screen & webcam recorder

Capture your screen, camera, or both — no OBS, no install. Records straight into a layer you can trim, resize, and lay out picture-in-picture.

Layer-based timeline editor

Stack text, shapes, images, video, and audio on a keyframe timeline. Drag clips to reposition, split, ripple-cut, and animate — like CapCut, in the browser.

Auto captions & subtitles

Generate captions from your audio and burn them in, or translate and dub into another language. Great for TikTok, Reels, and Shorts reach.

AI editing by prompt

Tell the studio what to do — “make it a TikTok and put me bottom-right as a circle,” “fade the headline in” — and it makes the edit for you.

Templates & viral formats

Start from ready-made packs — mock chat stories, Reddit reads, fake tweets, quizzes, rankings — then swap in your words. A Canva-style head start.

Text, stickers & overlays

Animated headlines, blend modes, news-ticker lower-thirds, and pastable stickers. Add a blur/mosaic box to redact anything on screen.

Speed, crop, filters

Ramp clip speed, freeze frames, freeform-crop, flip, Ken-Burns zoom, and colour-grade with brightness, contrast, saturation, and one-tap looks.

Voiceover & audio

Record a voiceover, add AI text-to-speech, layer a music bed, and fine-tune volume with fade in/out per track.

Export MP4 — no watermark

Render a clean MP4 in your browser with WebCodecs, or a server render for long/HD videos. Presets for IG Post, Story, TikTok, X, and YouTube.

A CapCut, Canva & OBS alternative in one tab

Instead of CapCut: a real timeline with split, trim, drag-to-move clips, speed ramps, freeze frames, keyframe animation, filters, and MP4 export — no app to install.

Instead of Canva: ready-made video templates and viral formats, animated text, stickers, brand overlays, and one-tap sizes for every platform.

Instead of OBS: a built-in screen and webcam recorder that drops your capture straight onto the canvas, so you record and edit in the same place.

And on top of all of it, an AI edit bar — describe the change in plain English and the studio makes it.

Frequently asked questions

Is Neuron Studio a free online video editor?+

Yes. You can record, edit on the timeline, auto-caption, use templates, and export an MP4 free in your browser. There's no watermark on your exports and nothing to install.

Is it a good CapCut or Canva alternative?+

It covers the same ground: a layer-based timeline with split, trim, speed, crop, filters, and keyframe animation like CapCut, plus ready-made templates and text/branding tools like Canva — all running in the browser with an AI edit bar on top.

Can it record my screen like OBS?+

Yes. The built-in recorder captures your screen, webcam, or both and drops the recording straight onto the canvas as an editable layer, so you can record and edit in one place without OBS.

Can it add captions and subtitles automatically?+

It can generate captions from your audio and burn them into the video, and it can translate and dub your audio into another language — ideal for TikTok, Instagram Reels, and YouTube Shorts.

Do I need to download or install anything?+

No. Neuron Studio runs entirely in your web browser. Your media stays on your device, and you can save projects locally and reopen them anytime.

What formats and sizes can I export?+

Export MP4 with one-tap presets for Instagram Post (1:1), Instagram/TikTok Story (9:16), X (16:9), and YouTube (16:9). Quick in-browser exports or a server render for longer, higher-resolution videos.
