ReadTube turns your YouTube and Bilibili subscriptions into a readable, searchable personal newsletter by using AI to transcribe, generate one-line headlines, short summaries, and full narrative rewrites of long videos (a 20‑minute talk becomes a ~5‑minute read) and to perform in-place translations with the same model that produced the article; it also uses AI-powered semantic search and persistent, timestamped notes so your subscriptions become a durable, retrievable knowledge archive rather than an endless autoplay feed, and you can self-host or bring your own API keys to run the generation.
