Best for running a systematic review with AI help
Nested Knowledge runs a whole systematic review in one place, and the first review project is free for one person with no time limit. Sharing it needs paid seats for everyone, the full AI features start at $69.95 a month, and commercial plans cost $295 or $695 per user a month. It is web only.
Who Nested Knowledge is for
- Fits if you run a systematic review alone and want to start free
- Works for academic teams who would pay the Academic seat price
Who Nested Knowledge is not for
- Not for you if you work as a team on the free tier, as free users cannot be invited to a shared project
- Pricey if you are a company at $295 or $695 per user a month
- Tight if you want the AI screening, which needs Academic+ at $69.95 or higher
- Watch out: after cancelling, projects stay viewable and exportable but cannot be updated
Why Nested Knowledge gets a 2.0
Five grades, each with its reason. The GPA is their average: an A is 4 points, an F is none.
- DValue for moneyAcademic is $19.95 per user a month, above the category's $14 dearer-quarter line. The AI features sit on Academic+ at $69.95, and commercial seats are $295 and $695.

- CFeaturesScreening, extraction, synthesis, living reviews and AI tools. The listing shows collaboration and the full AI suite locked behind paid seats.
- CEase of useNo store rating on record, and a review needs a project built and set up before anything works.

Keep Nested Knowledge, or make your own?
Keep it
To replace Nested Knowledge 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: 54 of the 69 other AI research tools grade higher. It costs $239.40 a year.
What you could make
- Reports: an app builder makes this well.
What you could not
- A library of papers and sources to search.
- Several people working in it at the same moment.
- AI features, unless you pay a model provider for each request yourself.
What this rests on. Nested Knowledge’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.
What is Nested Knowledge?

- Prices are tax-exclusive, and Stripe self-service checkout is monthly or annual.
- After cancelling, existing Nests stay viewable and exportable but can no longer be updated.
