How this list was built: alternatives are tools from the same area of the Ai Siftly catalogue, ordered by website-domain popularity (Tranco research list, 2026-10-26; method), then tools without a rank. Prices and details come from each vendor's own pages with the date checked shown. This is not a ranking or a recommendation.
Yes. Perplexity, Consensus, Elicit and Zotero each list a free plan (checked dates shown above). scite itself is paid-only in the catalogue's records.
Zotero storage starts at $20/year (checked 2026-10-31), but it organizes sources rather than answering questions. For AI answers, Consensus Pro is $12/month billed annually (checked 2026-10-27) and Perplexity Pro is $17/month (checked 2026-10-30).
scite's support-or-contrast Smart Citations are its distinctive feature. Consensus cites peer-reviewed papers in its answers, and Elicit extracts evidence into review tables, but neither replicates Smart Citations exactly.
