| Source | Rating | What it says |
|---|---|---|
| G2/Capterra | Not G2-listed as traditional SaaS (Google Labs heritage); community sentiment 4.3–4.7/5 on “trustworthy citations + Audio Overview” | |
| AIUnpacking / Glasp / Fello | “grounded RAG best-in-class, Audio Overview still undefeated, free tier shockingly complete” | |
| Storyflow alt-test | “50-source cap hurts 73-doc corpus; no canvas to link ideas; chat forgets structure between sessions” | |
| Power-user gripes | Free 50 chats/3 audio burn by noon; tables/figures/LaTeX fumbled; scanned PDFs OCR-rough; Deep Research can’t hit PubMed/arXiv directly; no API = can’t pipe into Obsidian/Notion automations | |
| 2026 dev survey | Satisfaction ~81% for “source-grounded study”, but 23% dual-wield ChatGPT/Claude for writing after NotebookLM extracts |
