How it works
Upload the long video
Podcast, talk, interview, lesson… up to 2 hours and 1 GB. Choose how many clips and how long.
The AI proposes, you choose
Whisper transcribes and a language model proposes 6 to 10 moments with a score and a reason. You tick the ones you want, adjust the cut, title and hook, and the 9:16 crop follows the speaker's face.

We measured it
- A 4-minute video produced 2 vertical 1080 × 1920 px clips with captions in 149 seconds. (19-09-2026)
Measured on airpic.app with the GPU already running. If nobody has used it for a while, the first job takes 40 to 90 seconds longer to start.
Frequently asked questions
How does it choose the moments?
Whisper transcribes the video and a language model (Qwen3, Apache-2.0) proposes 6 to 10 self-contained moments, each with a 1-10 score and the reason. You tick which ones to render, adjust start and end in 2-second or half-second steps, preview the cut before rendering and edit the title and hook.
What about framing?
We detect the speaker's face at each moment and the vertical crop follows it smoothly, without jerks. If there are no faces, it centres the picture.
Can I remove the captions or the title?
Yes, each has its own checkbox. Captions are in the video's language with the active word highlighted, and the SRT comes separately if you prefer the platform's own.
How long does it take?
About 2-4 minutes for a 30-minute video and 3 clips (transcription, selection and rendering), plus 1-2 minutes if the engine starts cold.
Which input formats?
MP4, MOV, WebM, MKV and AVI. Output is MP4 H.264 at 1080×1920 and 30 fps, accepted by every platform.
Do you keep my videos?
No. The video is processed and deleted: 1 hour after download, 24 h at most. No copies.
Can I add my logo and brand colours to the clips?
Yes: under Brand you choose the colour of the highlighted word, type your @handle and upload your logo as PNG, JPG or WebP. Your browser remembers them for next time.
How many clips can I make, and how long are they?
The AI proposes several moments and you render up to 5 at once. You adjust each one's start and end before rendering and can preview the cut on the page.
Is it free to make shorts?
Finding and choosing the best moments is free, with no account. To download the clips you get 1 free full-size download a month; after that you pay with credits that never expire, no subscription.
