Reel Recall
A long-video study companion that lets students ask questions across an entire three-hour recorded lecture or a full meeting recording and get answers with exact timestamps, powered by efficient long-context inference.
University students and self-learners working through long recorded lectures, conference talks or tutorial series
- Upload a 3+ hour lecture recording and ask natural-language questions that return answers with the exact minute-and-second timestamp
- Auto-generated study guide that pulls out definitions, formulas and key claims into a flashcard deck you can review
- "Compare two lectures" mode for students juggling multiple professors that highlights where they cover the same concept differently
- Saved threads per course so you can build a personal Q&A history across an entire semester
Efficient long-context inference (Hybrid SWA reducing KV cache to roughly 1/7) makes it finally affordable to ask questions across full-length video rather than short clips, opening up the back catalog of recorded lectures and webinars.
AI-in-education market is ~$7-8B in 2025 with 26-34% CAGR forecasts, and a direct competitor (AskYourVideo.io) already ships 3-hour video Q&A with timestamps plus adjacent tools (AskVideo.ai, LectureScribe, Memrizz, NotebookLM) validate real pull from students and podcast learners.AI In Education Market Size, Share And Growth Report, 2033 ↗Ask Your Video - AI for Long YouTube Videos | Podcasts, Lectures & More ↗
Space is already crowded: AskYourVideo explicitly markets 3-hour videos with timestamped answers for lectures/podcasts, NotebookLM handles YouTube, plus AskVideo.ai, LectureScribe, and Memrizz occupy adjacent niches — differentiation will need to come from cost/scale via Hybrid SWA, not from category novelty.Ask Your Video - AI for Long YouTube Videos | Podcasts, Lectures & More ↗I tried NotebookLM's top competitors to see how they compare, and here ↗
Proven pricing model in the niche: AskYourVideo charges $4.99–$49.99/mo with 1 hour free, billed per minute of video — students tolerate ~$5–$20/mo for clear value (NotebookLM Pro similarly priced), but margins are squeezed by long-context compute costs unless SWA-style efficiency is real.Ask Your Video - AI for Long YouTube Videos | Podcasts, Lectures & More ↗Different Revenue Models of a EduTech Platforms in 2025 ↗
Education AI secular tailwind is strong (CAGR 26%+) and recorded content back-catalogs keep growing, but long-context inference is commoditizing rapidly — Google, OpenAI and open-source models are pushing native long context, so the cost edge from Hybrid SWA may be short-lived (2–3 year window).AI In Education Market Size, Share And Growth Report, 2033 ↗
Stack is well-trodden (Whisper/ASR + long-context LLM + vector store) and the cited Hybrid SWA optimization reportedly cuts KV cache to ~1/7, making 3-hour video Q&A economically tractable for a small team; main risk is video-frame ingestion and scaling ingestion of very long recordings.
