Proven

69 defects found.

Every one caught before fab — saving weeks of reorder turnaround and thousands of dollars in scrapped boards. These are real defects from real designs, not theoretical.

Output capacitor underrated. Regulator stability requires minimum ESR and capacitance — board would brown-out under load.
MCU power pin not connected. Chip would never boot — invisible on a schematic review, caught by pin-level datasheet audit.
Boot pins floating. Microcontroller would enter wrong boot mode on power-up. Strapping pins must be defined.

The pipeline

From sentence to shipping-ready board

Jump in wherever you are. Describe a board from scratch at Design, upload an existing netlist to Validate, or drop a design in to Simulate. Every stage checks before the next begins — failures loop back automatically, with no silent errors.

Why PromptPCB

Grounded results, not guesses

PromptPCB pairs state-of-the-art AI models with a purpose-built suite of engineering tools and custom hardware data structures — netlists, footprints, pin maps, datasheet tables, power-rail graphs. Every decision is grounded in real data, not generated from memory.

An AI model on its own

  • Hallucinates part numbers that don't exist
  • Guesses pin functions with no datasheet to read
  • Can't verify stock or footprint availability
  • "It should work" — no simulation, no proof
  • No DRC, layout, or manufacturing files
  • Still needs an engineer to validate everything

PromptPCB: models + tools + real data

  • Frontier models orchestrated across a full suite of EE tools
  • Structured netlists, pin maps & power rails the model can reason over
  • Reads the actual datasheet for every IC — pins, ratings, tables
  • Every part grounded in real JLCPCB stock and footprints
  • SPICE-level simulation with a zero-warnings policy
  • Auto-placement, routing, DRC, and gerber export
  • 20-point expert review catches what simulation misses
Simulation

Not just schematics. Physics simulation.

DC analysis, transient simulation, thermal heatmap, and live oscilloscope traces — all running on the actual circuit before you fab.

Output

From layout to manufacturing files.

FAQ

Questions engineers ask

What about my IP? Will my designs train your AI?

No. Your designs are never used for training. All files are processed in isolated sessions and deleted after review. You can request full deletion at any time. We use third-party LLMs (Claude, Gemini, GPT) with their enterprise APIs — none of them train on your data either.

What netlist formats do you support?

KiCad (.net, .kicad_sch), EAGLE (.sch / project .zip), EasyEDA JSON, Altium (.SchDoc / .NetList), and screenshot-based capture. If you have a schematic image, we can parse it. Upload any format and we'll detect it automatically.

What if the review finds nothing wrong?

You still get the full report — verified checks, component analysis, and datasheet cross-references. A clean review is valuable confirmation. You're only charged if the review completes successfully.

How is this different from ERC in KiCad?

ERC checks electrical rules. We check against actual datasheets — is this capacitor the right value per the regulator's datasheet? Is this boot pin configured for the right mode? Are the abs max ratings respected? Things ERC can't see.

Can I use this for production boards?

The review product is production-ready today — engineers use it to catch defects before fab. The design tool (Board Design) is in beta. We recommend using it for prototypes and validating critical sections with your own review before production runs.

How long does a review take?

Typically 2-5 minutes for boards under 100 components. Larger boards (200+) may take up to 10 minutes. You'll see real-time progress as each datasheet is extracted and each check runs.
