AI video title and description generator
Upload a video and Refract’s AI looks through it, then writes a title, a description, captions for each app, and hashtags. Your video file stays on your device.

How it works
The AI looks through it
Your browser takes still frames from the video. Only those frames and your notes go to the AI.
Edit and post
Pick a title, copy the description and captions, and add the post to your week.
What the AI writes for you
Every analysis gives you text for each app you post on. Pro looks at more of the video and adds tools for search and editing.
Ready to post
Title options, a YouTube description, captions for TikTok, Reels, and YouTube, hashtags, hooks, and on-screen text.
Link import
Paste a link to your own TikTok or YouTube post and work from its cover and caption.
Deeper analysis
16 moments per video, the best thumbnail moment, scene by scene notes, chapters, keywords, and alt text.
Your video stays yours
Refract never uploads your video file. Your browser takes a few still frames from it, and only those frames and any notes you type are sent to the AI to write your text. Refract doesn’t keep the frames after the analysis. Read the privacy policy for the details.
Tips for better results
The AI works from what it can see and what you tell it. A little context goes a long way.
- Add a one-line note.
Say what the video is about, like “my sunday meal prep, 4 lunches for $20”. It helps the AI name things correctly.
- Paste what you say.
If the video has talking, paste your script or key lines. The AI can’t hear the audio, so this fills the gap.
- Pick the apps you post on.
Refract only writes captions for the apps you choose.
- Treat it as a draft.
Read every line before you post. Change anything that doesn’t sound like you.
Questions
Is the AI video analysis free?
Yes, with a free account you get 5 analyses a day for videos up to 3 minutes. Pro gives you 25 a day for videos up to 15 minutes, with deeper results.
Is my video uploaded?
No. Your browser takes a few still frames and sends only those, plus any notes you type. The video file never leaves your device.
Which video files work?
Any video your browser can play, such as MP4, MOV, or WebM. If one won’t open, export it as an MP4 and try again.
Can I use a link instead of a file?
Yes, for TikTok and YouTube posts that you own or have permission to use. Refract reads the public title, caption, and cover image. Instagram links can’t be read by apps like Refract, so upload the file instead.
Which AI does Refract use?
Claude, an AI model made by Anthropic.
