Video to Hashtags, Caption, Keywords and Hooks
Upload your video. The page looks at 6 frames sampled across your video, matches them against a fixed list of about 70 scene types, and combines that with the short description you type, to suggest hashtags, a caption, keywords and hooks. It does NOT currently listen to the audio, so it cannot know what is said in the video. This is a reduced version: it understands scenes, not speech. Everything runs on your device and the video is never uploaded.
Memory warning: everything runs inside your browser and looking at the video needs roughly 1 GB of free memory. On phones or small computers the page may freeze or close, and reloading or retrying does not guarantee it will work. This has only been tested on a small desktop-class test machine, not on real phones. Speech analysis is switched off: in my tests the in-browser speech model crashed the page about half the time on a small machine, so it is not offered here.
First use downloads one AI model (the image model, about 89 MB), then your browser keeps it for next time. Use Wi-Fi. Works best in Chrome on a recent phone or laptop.

Tips to help this video do better
Tips come from your video's measured length, shape and motion plus general short-video practice. Nobody can guarantee views or virality, and buying fake engagement can get an account banned.

This free tool is made by TechVani AI, a student-focused education and tech blog (techvaniai.blogspot.com). It helps creators get ideas for hashtags, captions, keywords and hooks from their own video. Suggestions are machine generated from simple scene recognition on a few frames and the description you type, so they can be wrong. Review everything before you post.
Privacy Policy
Your video stays on your device. The video file is read and analysed inside your browser. It is not uploaded to our servers, and we do not have servers that receive videos, transcripts, descriptions or results. When you close or reload the page, the results are gone.
What loads from other services. To run, the page downloads its code from jsDelivr (cdn.jsdelivr.net) and an AI model file from Hugging Face (huggingface.co). Those services can see your IP address and browser details when you load the page, as with any website. Your browser may store the model files in its cache so later visits are faster. You can clear them in your browser settings.
Cookies and tracking. This page does not set cookies, does not use analytics, and does not show ads. The Google Trends, YouTube and Instagram links open those sites in a new tab, and their own privacy policies apply there.
Children. The tool is not directed at children under 13.
Changes. If this tool later adds analytics or advertising, this policy will be updated before it does.
Terms of Use
The tool is free and provided as is, without any promise of accuracy, availability or results. We do not guarantee views, reach or income from using the suggestions. You are responsible for the videos you post and for following the rules of each platform and the law, including copyright. Do not use the tool on videos you have no right to use. We may change or stop the tool at any time.
