Invenio is a revolutionary video search engine that harnesses the power of transcripts to help you find any YouTube video instantly, even if you only know a few spoken words from a clip.

With Invenio, all you need to do is type in a few words from the clip, and our AI powered app will search through over 1 Billion YouTube videos to locate the original video within seconds. Invenio's innovative search algorithm doesn't just look for video titles or descriptions – it scans the actual spoken content of each video. Simply enter a phrase or sentence you remember from the clip, and Invenio will return a list of matching videos, ranked by relevance.

Invenio's advantage is ratings volume (4 vs 1). On price, rating, review sentiment and ads there is nothing between them.
