Captions, hooks and animated blocks for Reels, TikTok and Shorts

Pick a look, answer five short questions or edit every frame, then export a finished video from your browser.

No card needed. Your video is edited on your device and is not uploaded.

59 looks, and every one is editable

Each look sets colors, fonts, captions, a hook and animated blocks. Your video and your words stay as they are.

Previews show the real overlays on placeholder footage.

Describe the video, or edit every frame

Both ways use the same project, so you can start in one and finish in the other.

Automated

Five steps: format, look, font, motion and content. Each step has a prompt bar that understands plain words, with the options visible underneath. Or write the whole request once and let Kontentor fill in the steps.

Advanced

Every option in seven tabs plus a timeline. Drag any page, block or hook left and right, pull an edge to trim it, and snap to the playhead.

What is inside

Built for short vertical video, with the safe zones of each app on screen while you work.

Four-color system
Pick one color and get Text, Accent, Surface and Support that work together. Highlighted words, blocks and outlines all draw from them.
Captions that follow speech
Word-level timing from automatic transcription, in English, German or Croatian. Karaoke, outline, box and pill styles.
39 animated blocks
Stats that count up, lower thirds, pointers, bar charts, Reel-style titles, and a video window that shrinks the clip into a colored frame.
Cinema grade
Gradient, grain, light spill, lens glare, color split and bloom. The grade is part of the export, not just the preview.
Hooks
A claim, question, number, open loop or pattern interrupt in the first seconds, with ideas written from your topic.
Export
MP4 or WebM, 24 to 60 fps, 720p on Free and up to 4K on Pro. Subtitles as .srt, or the overlay alone with a transparent background.

Your video stays on your device

Edited in the browser

Preview and export run on your computer. The finished file is created there and saved to your downloads.

Audio only, only on request

Automatic captions send the audio track to the transcription service when you press the button. Nothing else leaves your device.

Projects, not footage

Saved projects store your text, colors and timing. They do not contain your video.

Questions

Is my video uploaded?

No. The video is opened, edited and exported in your browser. Only the audio is sent, and only when you press Auto-transcribe.

Which browser should I use?

Chrome or Edge on a computer give the best results. Safari exports too but skips the pixel-level color grade. The editor is built for a desktop screen.

What changes when I upgrade?

Pro removes the watermark, raises the export size from 720p to 4K, and gives you more automatic captions and hook ideas each month. The looks and blocks are the same on both plans.

Can I change a look after I build the video?

Yes. Swap the look, change the font, colors, captions, hook and blocks, or drag anything on the timeline. Nothing is locked.

Who makes Kontentor?

Emporiant e.U. in Graz, Austria, on the IRIDIUM platform.
