๐ง
NotebookLM
Research ยท freemium
Pros

- โFast Research and Deep Research can add web sources to the notebook
Cons
- รThe free plan caps you at 100 notebooks and 50 sources per notebook
- รInteractive Audio Overview is English-only, and so is the Longer length option

SciSpace Deep Review
Research ยท freemium
Pros
- โSearches a very large 280M+ paper corpus, broader coverage than many rivals
- โAgentic loop refines queries automatically instead of one-shot keyword search
- โEvery claim in the drafted review links back to a source paper
- โNative Zotero and Mendeley import fits academic citation workflows
- โVendor benchmark claims roughly 2x the relevant-paper recall of Elicit
Cons
- รDeep Review is locked behind the ~$90/mo Advanced plan โ far pricier than Elicit or Consensus entry tiers
- รThe 26.3-vs-13.0 papers-per-query benchmark is vendor-run and unverified by third parties
- รAI-drafted reviews still need manual fact-checking; a first pass, not a finished manuscript
- รFree tier excludes Deep Review entirely, so you can't trial the headline feature without paying
