Best for managing a reference library for free
Mendeley is Elsevier's reference manager, free with 2 GB of storage. The AI features inside it need a paid LeapSpace plan at $26 a month billed yearly, which Elsevier says isn't for corporate use.
Who Mendeley is for
- Fits if you want a no-cost reference library and don't need AI
- Works for researchers already using Scopus or ScienceDirect
Who Mendeley is not for
- 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
Why Mendeley gets a 2.2
Five grades, each with its reason. The GPA is their average: an A is 4 points, an F is none.
- DValue for moneyThe AI features are on LeapSpace Individual at $26 a month billed yearly, more than twice the research middle of $10 and inside the dearest tenth, which starts at $20. The free LeapSpace tier excludes the AI inside Mendeley.
- BFree plan and trialThe reference manager is free with 2 GB of storage, and a person can live on it. The LeapSpace free tier has unlimited AI for only 14 days, then limits.
- CFeaturesA reference library, Ask My Library, a Reading Assistant, Compare Experiments and a Word add-in. The AI bits sit behind the paid plan, and desktop support couldn't be confirmed from the pages read.
- CEase of useNo store rating on record. A reference manager means importing a library, setting up folders and a plug-in.
- BPlatforms and integrationsListed as web only, because desktop apps couldn't be confirmed. It has a Word add-in and connects to Scopus and ScienceDirect.

Keep Mendeley, or make your own?
Keep it
To replace Mendeley you would be making a library of papers and sources to search. That is not a weekend's work, with an AI app builder or without one.
That makes this kind of software worth paying for, not this one in particular: 31 of the 49 other AI research tools grade higher. It costs $312 a year.
What you could make
- Highlights: an app builder makes this well.
What you could not
- A library of papers and sources to search.
- An AI model, which you can rent by the request but not make.
- Citation records for millions of papers.
What this rests on. Mendeley’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
