Good · out of 4.0 · graded Nov 12, 2026
Best for searching papers, grants and patents in one database
Dimensions is a linked database of publications, grants, datasets and patents, and its free version covers search, analytics views, export and AI summaries. But that's for personal, non-commercial use only, and every paid product goes through a demo with no published price.
Who Dimensions is for
- Fits if you're a student or researcher who wants to find papers and grants for free
- Makes sense if you look up who funds what and who has cited what
Who Dimensions is not for
- Not for you if you work at a company, since the free version is personal and non-commercial only
- Skip it if you want to manage references or screen papers, as it isn't a reference or review tool
- Watch out: the full products have no published prices and go through a demo
- Watch out: the ChatGPT tool needs ChatGPT Plus or Enterprise
Why Dimensions gets a 2.8
Five grades, each with its reason. The GPA is their average: an A is 4 points, an F is none.
- AValue for moneyThe free version is no cost and covers search, analytics, export and AI summaries, which is a lot for a research database. Paid products have no listed price.
- BFree plan and trialThe free version has no stated cap, but it's personal and non-commercial only, so a company can't use it.
- CFeaturesA database and analytics tool with AI summaries. The listing says it is not a reference manager or a review screening tool, so you need other software alongside.
- CEase of useNo store rating on record. Search and filters take some learning, and the paid apps go through a demo.
- BPlatforms and integrationsWeb, with ReadCube, ORCID and ChatGPT. Dimensions Research GPT is described for ChatGPT Plus and Enterprise users.

Keep Dimensions, or make your own?
Keep it
To replace Dimensions 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.
It is one of the better ones too: its GPA of 2.8 is higher than 41 of the 49 other AI research tools we grade.
What you could not
- A library of papers and sources to search.
- A search engine with an AI model behind it.
- Citation records for millions of papers.
- It plugs into other products, ReadCube, ORCID and ChatGPT among them, and has an API.
What this rests on. Dimensions’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.
