# TalkifyTube

> TalkifyTube is an AI-powered web application that lets users chat with any YouTube video by conversing with its transcript. Paste a YouTube URL, ask questions, get summaries, and extract insights — without watching the video.

TalkifyTube is a SaaS product (not affiliated with YouTube or Google). It retrieves YouTube video transcripts (auto-generated or manual captions) and uses large language models to enable natural conversation with the content. All AI responses are strictly grounded in the video transcript — TalkifyTube does not use general knowledge as a fallback and will not hallucinate facts beyond what the transcript contains.
