QuPath
BeginnerFree, installs on an ordinary laptop, and does not upload your slides anywhere. The usual first stop if you have never used digital pathology software.

Built by Dr. Atul Tiwari, a pathologist, for fellow pathologists
Everything in AI for pathology,
and whether you may use it.
From the paper to the plugin to the product. Every entry records what it costs, what hardware it needs, whether it works offline, whether it uploads your slides, and where it stands with regulators.

How deep do you want to go?
Pick a level and everything below is filtered to it. Pick it again to see the lot. Levels come from what an entry actually needs — the hardware, the setup, whether there is code involved — not from anyone’s opinion.
Nothing in the library sits at that level yet. Pick another, or browse everything.

Free, runs on the machine you already have, and keeps your slides on it.
PathGPT
BeginnerThe most useful part is the structure, not the individual prompts: it shows how to build a prompt that can be evaluated rather than just admired.

Digital Pathology Association
BeginnerA good starting point if your department is considering going digital and wants peer experience rather than vendor material.

Hematogones.com
BeginnerPractical rather than clever — the sort of thing that saves ten minutes a day.

OpenFlexure Microscope
BeginnerThe genuinely low-cost option. You print the body, add optics and a Raspberry Pi, and get automated scanning for telepathology or teaching.

PathologyOutlines
BeginnerNot an AI tool, but the reference most pathologists already use — included because AI outputs should always be checked against a trusted source.

Cleared for clinical use
Each links to the regulator’s own record, with the date it was checked.
Prognostic AI test using digital pathology images for breast cancer.
- Paid
Answers a different question from a detection tool: not 'is there cancer' but 'how is this likely to behave'.
- Paid
Runs after you have signed out, and raises a flag if it disagrees. Designed as a safety net, not a first opinion.
- Paid
Anatomic pathology workflow and image analysis platform.
- Paid
The scanner itself, not an AI tool — it produces the digital slides everything else works on.
- Paid
Whole-slide image viewer for primary diagnosis.
- Paid
Read before you deploy
Validation guidance, reporting standards and the documented failure modes — the part that gets skipped.
If your laboratory is going digital, this is the document your validation study will be judged against. Read it before you buy a scanner, not after.

DECIDE-AI
BeginnerThe stage most pathology AI has never been through. Worth asking a vendor whether their product has.

EU IVDR 2017/746
Beginner'CE marked' under the old directive and under IVDR are not the same claim. Check which one a vendor means.

Known Failure Modes in Pathology AI
BeginnerRead this before trusting any performance figure. Most published accuracy is measured under conditions that do not resemble a working laboratory.

The most important cautionary result in computational pathology. It explains why a model reporting excellent accuracy on TCGA may fail completely on your slides.

Or start from what you need to do
Four questions, answered for every entry
Can you legally use it?
Every cleared device links to the regulator’s own record, with the date it was checked — never to a vendor’s marketing page.
Will it run on your machine?
Hardware floor, offline capability and cost are recorded per entry. No assumption that you have a cluster.
Do your slides leave the building?
Recorded as a field, not buried in terms of service. The first question to ask of any hosted tool.
Is it still alive?
Activity is refreshed nightly. Projects that have gone quiet are shown as such rather than quietly dropped.
