TranscriptAPI is YouTube-only, so it is not a general video tool. It requires an account and API key, each request consumes credits, and costs scale with calls. The pricing page returned no readable content, so plan prices and free-tier limits are unknown. Check before building on it.
Gemini Notebook (formerly NotebookLM) is Google's source-grounded assistant: add sources and it answers questions and builds summaries, audio and slides. It has a free tier; a paid starting price is not stated in our verified data. It is an app, not a REST API. Perplexity is an answer engine with cited sources and developer search APIs, with a free tier and Education Pro at $10 per user (student or faculty verification required). Use it when you need web search results rather than transcripts. Neither replaces a transcript endpoint.
"Better suited" below is based on documented features and pricing from our verified profiles, not on a head-to-head test. Prices are USD as published by each vendor.

Taken from the documented limitations in our TranscriptAPI profile.
| Tool | Starting price | Free tier | Platforms | Main limitation |
|---|---|---|---|---|
| TranscriptAPI (this page) | Not published | Yes | API | The pricing page returned no readable content, so plan prices and free-tier limits are unknown, and it covers YouTube only. |
| Gemini Notebook (formerly NotebookLM) | Not published | Yes | Web, Mobile | Free tier has standard usage limits and 50 sources per notebook; higher limits need a Google AI Plus, Pro or Ultra plan, which Google says are only available in specific regions. |
| Perplexity | $10/mo (Education Pro (consumer, verified students/faculty)) | Yes | Web, API | The consumer pricing page is blocked to automated checks, so the Pro price could not be confirmed here, and free-tier Pro Search and Research access are described only as 'very limited' / 'limited'. |
