AI Tools: Search & research
For working from your own documents, Gemini Notebook is the strongest free tool going, and its opaque new compute limits are the price of that generosity.
Best for: Students, researchers and analysts who need to understand and cite a defined set of their own documents.
Price: Free; higher limits through Google AI Plus ($4.99/month, 2x), AI Pro ($19.99/month, 4x) and AI Ultra (about $100 or $200/month, 5x or 20x Pro). Included in qualifying Workspace editions; Enterprise version through Google Cloud.

AI Tools: Search & research
Still the quickest route from a question to a page you can check, though the gap with free Google AI Mode is now a matter of habit more than capability.
Best for: Students, researchers and professionals who want quick, sourced answers instead of a list of links.
Price: Free; Pro $20/month ($200/year); Max $200/month ($2,000/year); Education Pro $10/month; Enterprise Pro $40/seat/month ($400/year), Enterprise Max $325/seat/month ($3,250/year). Comet browser free; API billed separately.

AI Tools: Search & research
Elicit turns hundreds of papers into a cited data table, but a peer-reviewed test put its extraction accuracy at 86.6%, so it belongs beside a human extractor rather than in place of one.
Best for: Researchers, analysts and review teams who need to extract structured data from many academic papers.
Price: Basic free (unlimited search and summaries, limited agent and reports); Pro $49/user/month billed annually ($588/year); Scale $229/user/month billed annually ($2,748/year); Enterprise custom. Extra usage on Pro and Scale in $100 increments up to a cap you set.

AI Tools: Search & research
A fast, well-cited first pass at a research question that counts studies rather than weighing them, so the reading still falls to you.
Best for: Students, clinicians and curious readers who want a fast evidence check on a research question.
Price: Free (basic paper search, 10 Pro messages and 3 Deep reviews/month); Pro $20/month or $144/year (15 Deep reviews/month); Deep $65/month or $540/year (200 Deep reviews/month); Teams and Enterprise custom. Up to 40% off for students and clinicians.

AI Tools: Search & research
Undermind makes you wait minutes to find the papers keyword search misses, and at $16 a month it is cheap enough to run before every literature review.
Best for: Graduate students and researchers starting a project who need a thorough sweep of prior work.
Price: Free (standard rate limits); Pro $16/month billed annually, about $20 monthly (10x Free limits); Team $15/person/month billed annually; Enterprise custom.

MCP Servers: Search & knowledge
For anyone whose reading lives in Zotero this is the server to run, though its 17,000-token tool list makes the CLI skill the smarter route in coding agents.
Best for: Academics and students who keep their papers in Zotero and want an assistant to search, read and annotate them.
Price: Free and open source (MIT for the server and CLI; the in-Zotero chat plugin is AGPL-3.0). Hosted embedding providers are billed by them.

AI Tools: Search & research
Scite's Smart Citations are still the quickest way to see whether a finding has held up; nearly everything else it sells, Consensus and Elicit also offer.
Best for: Academics, students and science writers who need to check how a paper has been received before citing it.
Price: No free plan; 7-day trial that rolls into the chosen plan. Basic $12/month billed yearly ($144/year); Pro $40/month billed yearly ($480/year); roughly $20 and $50 on monthly billing, by the page's own savings figures. Enterprise custom.

GitHub Repos: Agent frameworks
The reference project for automated ML research and now a usable harness for coding agents, but its papers still need a human to catch errors, and every run executes code an LLM wrote.
Best for: ML research groups studying or using automated experimentation who can sandbox agent runs and will review every result before it is published.
Price: Free. v1 and v2 under the AI Scientist Source Code License 1.0 (use restrictions and mandatory AI disclosure); v3 under Apache 2.0. You pay for LLM API calls or subscriptions and GPUs.
