Upload raw footage or paste a script, then tell the AI video editor in simple text what you want changed. It trims, adds captions, and polishes your video into content that is ready to publish, with no video editing experience or complicated editing software required.
Key FeaturesFeatures of the AI Video Editor
Text-Based AI Video Editing Commands
Type a prompt describing the change you want, such as removing a section, tightening the pacing, or rearranging scenes, and the editor applies it as a precise cut. Deleting words in the transcript trims the matching footage, and you can even fix mismatched dialogue with AI lip sync, so you make edits the way you edit a document.
Automatic Captions and Subtitles
Generate accurate captions for any clip in seconds, then adjust wording, timing, and customisable caption styles with text animation before export. Because captions come from the built-in subtitle generator, spoken audio becomes clean on-screen text that keeps videos watchable with the sound off on social feeds.
AI Audio Cleanup and Natural Voice-overs
Clean up background noise, balance levels, and apply studio-grade audio enhancement without needing an audio engineer. Need a new voice-over? Swap or re-record lines using AI voice Cloning for natural-sounding narration that matches the original speaker across every revision.
One-Click Resizing for Every Platform
Reformat one edit into vertical, square, and widescreen versions in a single pass, or drag and drop elements to fine-tune each layout. The editor reframes subjects and repositions captions effortlessly for TikTok, YouTube, LinkedIn, and email, and the same source works for AI video adverts, so one source video covers every channel.
AI B-Roll and Cinematic Scene Fillers
Fill gaps in your footage with AI-generated scenes instead of stock video clips. Type a text prompt and Seedance 2.0 produces cinematic video with accurate motion and lighting that matches your cut, so transitions, intros, and cutaways no longer require a second shoot.
Use cases
Earlier, cutting a webinar into short clips used to take an entire day of scrubbing through timelines. Now the clip generator automatically picks out the strongest moments for you, creating captioned, reframed video clips that are ready for Reels, Shorts, and TikTok, so a single recording can give you a full week of engaging content.
Offers change faster than agencies can re-edit. Swap scenes, update text, apply video effects, and test new hooks on a promo video in minutes, so campaigns stay up to date without fresh production budgets or reshoots.
Screen recordings full of pauses and filler make weak training. Tighten each step, narrate with a cloned voice, and standardise style across modules, so teams get clear how-to and explainer videos that reduce repeated support questions.
Manually editing a one-hour episode can take up an entire working day. AI removes silences and filler words, cleans up the audio, and adds captions to the final output, so creators can publish more podcasts and YouTube episodes without needing to hire an editor.
Reshooting content for every market is unaffordable for most teams. Run any finished edit through the AI video translator and publish the same video in 175+ languages with perfectly matched lip movement.
Product videos need frequent updates as listings, prices, and features change. Replace scenes, swap video backgrounds, add text overlays, animate stills with image-to-video, and resize for marketplaces and social ads in a single workspace instead of rebuilding every variant from scratch.
How it worksHow the AI video editor works
Go from raw footage, or even a PDF to video source, to a polished, ready-to-publish video in four steps, with AI-powered tools in a single workflow handling the cuts, captions, and formatting.
Upload a recording or screen capture. The editor creates a transcript and scene overview.
View your video as text and scenes. Apply a brand template, then mark the sections you would like to change.
Type prompts to cut, add captions, clean audio, add effects, and resize. Each command becomes an edit.
Finalise the cut, then export in HD or 4K as MP4, along with appropriately sized versions for each channel.
An AI video editor is a tool that cuts, captions, and enhances videos from a plain language prompt instead of manual timeline work. It can even turn a PPT to video in the same workspace. The AI video editor makes studio-quality results possible in minutes by automating complex tasks like trimming, syncing, and captioning, so you edit videos with AI instead of scrubbing through a timeline.
Yes. Every AI edit remains fully adjustable, so you retain creative flexibility over the result. Fine-tune individual cuts, captions, scene order, and audio after each command; AI takes care of the repetitive editing tasks while you maintain frame-level control.
Open the transcript and the AI automatically flags filler words, pauses, and silences. Delete them in the text and the matching footage is trimmed, turning hours of manual scrubbing into just a few minutes of review, which is ideal when you pair it with the AI podcast generator.
