Part 01 · Overview

Welcome

What it is, who it suits, its grades and the ten things to know first

2.0

GPA, above 8 of the 69 other AI research tools we grade

Nested Knowledge is a web platform for running systematic literature reviews and meta-analyses. Its AutoLit workflow covers searching, screening, tagging, data extraction and critical appraisal, with optional AI features. Results flow into a Synthesis view with PRISMA diagrams and forest plots.

To get you started, here are 9 things to know about Nested Knowledge, taken from its own pages and our grades.

No store rating on record, and a review needs a project built and set up before anything works.
From our grade for ease of use
  1. 1

    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.

  2. 2

    Paid plans start at $19.95 a month for each person

    As its pricing page puts it: $19.95 per user / month (Academic).

  3. 3

    There is a free plan

    Your first Nest, an entire review project, is free with no time limit and no card; collaboration is not available on the free tier.

  4. 4

  5. 5

    AutoLit review workflow

    Structured searches across PubMed and Embase, plus single or dual screening, tagging, meta-analytic extraction and critical appraisal.

  6. 6

    Smart AI features

    Smart Search builds Boolean strings from a question, Robot Screener acts as a second reviewer, and Smart Tags extract data.

  7. 7

    Synthesis outputs

    Builds PRISMA diagrams, forest plots, network meta-analysis and summary tables that update as new data is added.

  8. 8

    A 2.0 GPA, above 8 of 69

    That is against the other AI research tools we grade, on value, the free plan, features, ease of use and platforms.

  9. 9

    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.

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 it 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

Good to know

Good for

  • Research teams running systematic reviews and meta-analyses
  • Pharma, medical device and health economics groups needing audit trails
  • Students and academics who can use the reduced Academic tier

Worth knowing

  • Collaboration needs paid seats for every collaborator; free-tier users cannot be invited to a shared Nest.
  • Commercial plans are $295 or $695 per user a month, and annual billing is offered at checkout without a published price.
  • 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.

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 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.
