Automated test planning
for firmware teams.

Plug in your BOM and requirements. Get a structured test plan with integration scenarios, edge cases, and coverage gaps you'd miss doing it manually.

What are we supposed to test before we ship this?

What happens if sensor read and flash write happen at the same time?

It passed all our bench tests. No idea why it's failing on site.

From BOM to test plan

The AI maps your firmware architecture and generates test cases grounded in how your hardware actually works. Coverage across every bus, every peripheral, the ways they interact, and where things could break.

Data security

Temporary storage, permanent deletion

usefirmware.com doesn't permanently store your datasheets and requirement documents. We extract relevant information during processing and keep only those excerpts until your test plans and reports are generated. Everything is deleted once you export the test plans or are satisfied with the coverage.

On-premises deployment available

For teams with strict data residency requirements, we offer on-premises deployment. Everything you do stays within your network. Your data never leaves your infrastructure.
