How It Works

Six easy steps from idea to ready-to-post clip

AI does the slow part first; you look it over and say yes, or change anything. Already have footage? Skip the script.

  1. Script

    Give a topic and AI drafts the script in sections, or paste one you already have.

  2. Footage

    Drop in what you shot and every word is transcribed, with free on-device Whisper or ElevenLabs.

  3. Story

    AI reads everything you said and offers a few takes on it: scripted, tight or storytelling.

  4. Storyboard

    AI picks your best takes and cuts the fillers. Preview scene by scene and revise in plain words.

  5. Finish

    Cover, hook, intro / outro, music and sound effects, pre-filled from your channel style.

  6. Edit & Export

    Get an MP4 with Thai subtitles and a post caption, or send it on to your favourite editor.

Features

Leave the fiddly work to Kutter

The parts you'd scrub through second by second, Kutter does for you, so you can save your energy for the fun part: the story.

1Auto-cut · Thai subs

Filler words and silences out, easy-to-read Thai subtitles in

Every word is transcribed with timing, only the unused parts are cut, and subtitles come from what you actually said, in sync on every line.

  • Cuts land on word edges, with 5 levels of tightness
  • Lines never split a word; key words pop in brand colour
  • 32 Thai fonts, or bring your brand's own
2Matte · B-roll

Put the speaker in front of B-roll, no green screen needed

Matte lifts the speaker off the background on your own computer and places them over B-roll that AI finds to match the words, so the clip never sits still.

  • B-roll from Pexels or your own clips, matched to what you say
  • Matte on or off per scene, GPU-accelerated
  • Automatic website screen recording for tutorials
3AI Voice-over

Rather not be on camera? Let AI narrate for you

Got only mood shots, products or a shop front? AI writes a script in your channel's tone, matches each line to a clip and voices it line by line.

  • Voices from Gemini or ElevenLabs, with an estimated cost before you generate
  • Dub a finished clip into 10 other languages

Finish it all on one screen

A cover from the sharpest frame, an opening title, intro / outro, your music or free tracks, plus whoosh and pop sounds.

Want a change? Just type it

Say “music's too loud”. AI shows what it will change first and keeps the old version, so you can always go back.

Export any way you like

MP4 in every size with SRT subtitles, or send to CapCut, Premiere, DaVinci or Final Cut, with a caption AI writes for you.

FAQ

Frequently asked questions

Installing and system requirements are on the download page.

Do I need to know how to edit video?

Not at all. Kutter walks you through step by step. Each step has a button to let AI go first, then you review; if you don't like something, say so in plain words. If you already edit, send the result on to the app you know.

Is it really free? How are AI costs charged?

Kutter is free during launch. With your own API key, you pay the AI provider directly for what you use. With Claude Code or Codex, it uses your plan's quota. On-device Whisper transcription costs nothing. If pricing changes we will announce it in advance, and we won't charge retroactively for the free period.

Is my footage uploaded anywhere?

Your video and project files stay on your computer; the app doesn't upload them to us. What goes out is only what an AI task needs, to the provider you chose, e.g. the transcript text to the AI that plans the story · More in the Privacy Policy

What if I don't like the AI's cut?

Change it at any step: edit the script or have AI rewrite it, pick another story, change the tightness, revise storyboard scenes, or after rendering just type what you want changed. Earlier versions are kept so you can go back.

What kind of computer do I need?

Windows 10/11 (64-bit) or a Mac with Apple Silicon (M1 or later). A graphics card speeds up on-device transcription and background removal but isn't required. See the system requirements.

Can I keep editing in CapCut or Premiere?

Yes. Send a layered CapCut project (with editable subtitles), XML for Premiere Pro and DaVinci Resolve, or FCPXML for Final Cut Pro, with SRT subtitles.

Can I make clips in other languages?

Kutter is built first for great Thai subtitles, and can dub a finished clip into 10 other languages as a separate clip with subtitles in that language. Your Thai clip stays as it is.

What is Hello AI?
