Fabric
Pros
- + Browser extension and quick-save capture are the fastest I have tested in this category — clipped pages kept full content plus a screenshot and were findable later by half-remembered phrases
- + Semantic search works across PDFs, OCR'd screenshots, transcripts, and clips: 'the pricing slide from the agency pitch' style queries returned the right file
- + Desktop app mounts Fabric as a virtual drive, which makes it feel like storage with an AI layer rather than another notes app
- + Free plan is genuinely usable for evaluation (250 MB, 1,000 items) with AI assistant and voice notes included, and Basic at $5/mo is cheap for 100 GB
- + Cited answers across meeting transcripts and research pulled the right source segments in my testing
Cons
- - AI assistant answers are inconsistent — third-party 2025/2026 app-store reviews report wrong answers and formatting requests ignored, and I saw occasional drift myself
- - Support runs through Discord only, with no email or phone channel, and third-party reviewers report no refunds on a $150–$390/yr product
- - Cloud-only: no true local vault or offline mode, despite the 'work offline' framing around drive-mounted streaming
- - Limited public transparency about company ownership and data practices; privacy policy deserves reading before uploading sensitive client material
- - Collaboration lacks the granular permissions larger teams need, and agent features are newer and less proven than the capture core
NotebookLM
Pros
- + Answers only from your uploaded sources with inline citations; in my cross-referencing the citation rate was effectively clean
- + Audio Overviews turn a research stack into a 10-20 minute two-host briefing in 80+ languages, with an Interactive Mode for follow-up questions
- + Free tier is genuinely usable: 100 notebooks, 50 sources each, at $0 (support.google.com/notebooklm limits)
- + Artifacts on tap: reports, flashcards, quizzes, mind maps, infographics, slide decks and video overviews
- + Refuses to answer outside the corpus instead of fabricating, which I found made summaries safe to act on
Cons
- - Bounded to your sources by design — useless for anything needing outside knowledge
- - Since 2 September 2026 the compute-based usage budget is easy to exhaust in one deep session on the free tier
- - Audio Overviews cap around 15 minutes, cannot be edited or partially regenerated, and offer no voice or format control
- - No tier lets you edit the audio script, and paid access requires a full Google AI subscription rather than a standalone plan
- - Retrieval and summarisation are strong; genuinely novel cross-source synthesis is weaker than a frontier reasoning model
