ShortsCutter
A publishing tool that turns long-form 3D graphics tutorials and live streams into short vertical clips, writes a description for each platform, and uploads them to the creator's own accounts.
ShortsCutter is built and operated by Danil Gryzlov, a 3D artist who publishes tutorials about Blender, ComfyUI and AI tooling for 3D graphics. It is a single-operator tool: it publishes only to the accounts its operator owns, and only content its operator produced.
What it does
1. Cuts the source video
A two-to-three hour stream recording is analysed for self-contained moments. Each moment is re-framed from 16:9 to 9:16, subtitled from a speech-to-text transcript, and rendered as a clip of 20–60 seconds.
2. Writes per-platform descriptions
Every platform has different rules — Instagram rejects a post with more than five hashtags, Pinterest never shows the description to a human, YouTube measures its description limit in bytes. ShortsCutter generates a separate title, description and hashtag set for each destination and validates them against that platform's published limits before anything is uploaded.
3. Publishes on a schedule
Clips are queued with a publication date and uploaded to the operator's own channels through each platform's official API. The operator reviews and approves every description before upload.
Platforms and permissions
ShortsCutter requests the narrowest permission that allows it to upload a video to the operator's own account. It does not read other people's content, does not post comments, and does not modify anything it did not create.
| Platform | Permission requested | What it is used for |
|---|---|---|
| YouTube | youtube.upload |
Upload a video to the operator's own channel and set its title, description, tags and thumbnail. |
| TikTok | video.upload |
Send a clip and its caption to the operator's TikTok drafts. The operator opens the app and publishes it manually. |
instagram_content_publish |
Publish a Reel to the operator's own professional account. | |
pins:write, boards:read |
Create a video Pin on one of the operator's own boards. | |
| VK | video |
Upload a vertical clip to the operator's own VK profile or community. |
How the data is handled
ShortsCutter runs locally on the operator's own computer. There is no server, no user accounts, and no third party involved: access tokens are stored on that machine and used only to upload the operator's own videos. The full detail is in the privacy policy.
