Mendeley vs SciSpace (2026): which should you pick?

Pick Mendeley if

• Fits if you want a no-cost reference library and don't need AI
• Works for researchers already using Scopus or ScienceDirect

Look elsewhere if

• Pricey if you want its AI features, at $26 a month billed yearly
• Not for you if you're buying for a company, since Elsevier says the plans aren't for corporate use
• Watch out: Mendeley Premium is now part of LeapSpace, per the pricing page
• Watch out: AI in the free LeapSpace tier runs unlimited for 14 days, then limited and not inside Mendeley

Pick SciSpace if

• Fits if you want search, reading and writing tools on one subscription
• Works for research teams of 2 to 300 people who want to be billed per user

Look elsewhere if

• Skip it if you're on Android, as the mobile app is listed for iPhone and iPad only
• Pricey if you run agents a lot, since the step past 1,200 credits is Advanced at $70 a month billed annually
• Not for you if you need the free limits in writing first, as they couldn't be confirmed
• Tight if you start several jobs at once, as Premium runs 4 tasks at a time and Advanced 8
• Watch out: prices come from an archived copy of the pricing page from 30 September 2026, and no integrations are listed

Mendeley

• AI features inside Mendeley need a paid LeapSpace plan; the free LeapSpace tier excludes them.
• The pricing page says Mendeley Premium is now part of LeapSpace.
• Platform support for desktop apps could not be confirmed from the pages read, so only web is listed.
• Elsevier says the plans are not for corporate use.

SciSpace

• SciSpace's site blocked automated reading, so prices come from an Internet Archive copy of its pricing page captured on September 30, 2026.
• The limits of the free tier could not be confirmed on a SciSpace page.
• Paid plans meter usage in monthly credits: 1,200 on Premium, 10,000 on Advanced and 40,000 or more on Max.
• The mobile app is listed for iPhone and iPad; no Android app was found on Google Play (US) when checked.
