The AI Agent that writes
and debugs your firmware.

Generate firmware from datasheets. Debug faults automatically. Every register cited. No hallucinations. Available as a VS Code extension and CLI tool.

Get Early Access — Free

Datasheet-grounded AI for Firmware.

Automate the tedious parts of firmware development with precision and verified accuracy.

Fast Peripheral Drivers

Convert datasheets into working peripheral drivers in minutes. Reduce manual register configuration time by over 80% with datasheet-grounded intelligence.

Verified Accuracy

Every line of code generated is cited to the exact page of your datasheet. Eliminate AI hallucinations and verify hardware addresses instantly.

Autonomous Debugging

Debug hardware faults by pointing the agent at your registers. Identify root causes and find the exact fix in seconds, not hours of manual tracing.

Product 1 — VS Code Extension

An AI Agent inside VS Code that understands your hardware.

Describe what you need. Point it at your datasheet. Get complete, verified firmware — every register address cited to the exact page. Then watch it debug your faults automatically.

  • Firmware Generation from Datasheets

    Upload your component datasheet. Describe what you need. Get complete firmware with every register address cited to the exact page. Not from training data — from your actual datasheet.

  • Autonomous Fault Debugging

    When your firmware crashes, the agent reads the fault registers, identifies the root cause, finds the exact line of code, and tells you how to fix it. In seconds. Not hours.

  • Zero Hallucination Architecture

    Every generated line is grounded in your datasheet. If the answer is not in your documentation, we say so. We never invent register addresses.

  • Works on 400+ MCUs and Boards

    STM32, ESP32, nRF52, NXP i.MX8, Raspberry Pi 5, Raspberry Pi 4, Arduino, and more. Every board has its own indexed datasheet database. Pre-loaded. No upload needed.

Product 2 — CLI Tool

hardcoreai — The firmware agent in your terminal.

Same AI agent. Lives in your terminal. Works over SSH. Works in CI/CD pipelines. Works without a browser. pip install and go.

  • hardcoreai generate Firmware from your datasheet in seconds
  • hardcoreai debug Autonomous fault analysis from UART logs or crash dumps
  • hardcoreai validate DTS and config validation before you build
  • Works in GitHub Actions, Jenkins, GitLab CI exit code 1 on errors. Automated firmware review.

✓ You're on the list. We'll ping you when hardcoreai validate ships.
