## SummifyAI

SummifyAI is a free Chrome extension and web app that summarizes YouTube videos in seconds using ChatGPT-class models. Beyond plain summaries, you can extract insights from specific timestamps, save reusable custom prompts, ask inline questions about any part of a video, and search full transcripts to jump straight to the moment you need.

**料金とプラン:** Freemium. Free access covers core features plus a small allotment of diamonds for pro features; a one-time lifetime membership gives unlimited diamonds forever with no monthly fee.

- **Instant video summaries:** Get an overview of any YouTube video in about three seconds without watching the whole thing.
- **Timestamp-based summarization:** Pull insights from only the sections you care about and skip the rest of a long video.
- **Reusable custom prompts:** Create and save knowledge-extraction templates, then reuse them on any video to pull the details you need every time.
- **Inline question answering:** Type a one-off question about a video and get an immediate answer drawn from its transcript.
- **Transcript search and navigation:** Search the full transcript and click a timestamp to jump to the exact moment, useful for long interviews and lectures.

**強み:** Very fast summaries, typically a few seconds per video; Free to install and use for basic needs; One-time lifetime option instead of a recurring subscription; Custom and inline prompts turn videos into a research tool

**制約・デメリット:** Focused on YouTube only, so other video platforms are not covered; Free tier is limited to a small number of 'diamonds' for pro features; Summary quality depends on transcript availability for the target video
