Part 01 · Overview
Welcome
What it is, who it suits, its grades and the ten things to know first
2.8
GPA, above 41 of the 49 other AI research tools we grade
Dimensions is a research database from Digital Science that links publications with grants, patents, clinical trials and policy documents. A free web version covers personal, non-commercial use. Institutions, funders, publishers and companies buy full access through its sales team.
To get you started, here are 8 things to know about Dimensions, taken from its own pages and our grades.
Search and filters take some learning, and the paid apps go through a demo.
- 1
Best for searching papers, grants and patents in one database
But that's for personal, non-commercial use only, and every paid product goes through a demo with no published price.
- 2
There is a free plan
Free version for personal, non-commercial use, with search, analytical views and export.
- 3
It runs on Web
Web.
- 4
Linked research data
The free version page cites more than 140 million publications and 29 million datasets, linked to grants, patents, clinical trials and policy documents.

A 2.8 GPA, above 41 of 49
That is against the other AI research tools we grade, on value, the free plan, features, ease of use and platforms.

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.

The report card
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.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | A | The 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. |
| Free plan and trial | B | The free version has no stated cap, but it's personal and non-commercial only, so a company can't use it. |
| Features | C | A 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. |
| Ease of use | C | No store rating on record. Search and filters take some learning, and the paid apps go through a demo. |
| Platforms and integrations | B | Web, with ReadCube, ORCID and ChatGPT. Dimensions Research GPT is described for ChatGPT Plus and Enterprise users. |
An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.
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 it 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
Good to know
Good for
- Individual researchers who need to look up publications and citations

- The free version is limited to personal, non-commercial use.
- Paid products have no published prices; access goes through a demo request.
- Dimensions Research GPT is described for ChatGPT Plus and Enterprise users.

41/49
Other AI research tools it is graded above
Dimensions's GPA of 2.8 is higher than 41 of the 49 other AI research tools we grade, and level with 6.

Keep it, or make your own?
Whether this is something you could build for yourself with an AI app builder, and what you would give up.
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.
