The reasons to look past ReadTube are mostly about uncertainty. Paid plans are not live yet and quotas will be introduced after the beta, so free use may shrink. Self-hosting needs your own API keys, so you pay model providers directly. Some video types are unsupported, and its pricing and docs pages returned 403, leaving plan details unverified.
Gemini Notebook, formerly NotebookLM, is Google's research partner that answers questions and builds summaries, audio and slides grounded in sources you provide; it has a free tier and a starting price is not stated in our data. Perplexity is an answer engine that searches the web and cites sources, with a free plan and an Education Pro tier at $10 per month for verified students and faculty. Neither is an inbox that follows channels, so the workflow differs.
