Andi
Pros
- + Completely free with no account, no ads and no tracking — I ran full research sessions without ever hitting a signup wall or seeing a sponsored result
- + Citation discipline is real: generated answers link to source passages I could open in the built-in reader, and narrow queries get search results instead of a forced guess
- + Result quality on SEO-spam-heavy queries beat Google in my side-by-side checks — manufacturer pages and forums surfaced above affiliate listicles
- + The Search API is genuinely developer-friendly: self-serve key, Google Custom Search-compatible REST shape, LLM-ready markdown, and the per-query charge reported inline in every response
- + Reader mode, Summarize and Explain make it usable as a research workflow, not just a query box
Cons
- - No enterprise features at all — no SSO, no DPA, no team administration, so procurement-heavy buyers have nowhere to go
- - API pricing has no public rate card; cost is 'under 1¢ per query' with the charge revealed per response, which makes budgeting guesswork
- - Index coverage falls short of Google on local, shopping and long-tail navigational queries — I still needed a fallback engine
- - The 87% accuracy figure is vendor-published and the benchmark development involved input from Andi to the Talc team; treat it as a claim to test, not a fact
- - Independent review coverage of the current product is thin and public team-size signals conflict (2 vs ~58), which matters for a company maintaining a 25-billion-page index
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
