Scarlet AI
AI that understands hardware workflows.
1Prompt

3SmowCode Compiler
4Binaries
No prompting skills required.
Users describe behavior in normal engineering language, not generic AI prompting tricks.
Generate or edit the flow.
Create a new flowchart, improve an existing flow, explain nodes, or add logic.
Easy manual control.
Edit every node, branch, variable, event, and custom code block.
Repeatable firmware output.
AI creates flowcharts. SmowCode software then generates the C code from known software blocks. This reduces hallucination risk in generated firmware output.
Industrial workflow
Use SmowCode to save time
Quick code reviews
Review firmware as graphical logic while keeping industry-grade code depth underneath.
Automate shipping workflow
Our teams will work with you to help you realise complex automation of development activities from idea to development, testing and shipping.
Connect tools
Integrate SmowCode outputs with engineering workflows, code pipelines, and team reviews.
No installation errors
No local toolchain setup, black-screen terminal errors, compiler mismatch, or driver friction for supported workflows.
RTOS and thread safety built in
Automatic RTOS workflows, queues, semaphores, and thread-safe patterns from visual firmware blocks.
Advanced controls
Lower-level firmware control when your team needs it.

FAQ
Let us answer your questions
What is SmowCode?
SmowCode is a graphical coding IDE with its own compiler. The SmowCode team has added an AI layer on top of graphical coding, so users can either code by dragging and dropping flowchart blocks or write a prompt and let AI generate the flowchart. This keeps teams at the logic level while still producing firmware.
What is the benefit of SmowCode in the age of AI?
Generic AI tools can generate code, but embedded teams still need repeatability, hardware context, reviews, flashing, debugging, and control. SmowCode uses AI to create or edit flowcharts, then uses SmowCode software to generate firmware from known blocks.

Is SmowCode just another AI code generator?
No. SmowCode is not just a prompt-to-code tool. Scarlet AI helps create and edit flowcharts, while the SmowCode platform handles graphical logic, compiler output, browser build, flashing, debugging, source download, and manual engineering control.
Is SmowCode just an AI harness?
No. The AI layer sits on top of SmowCode's existing graphical coding IDE, compiler, firmware blocks, and browser-based workflow. AI improves speed, but the platform itself provides the firmware development system.
Can engineers manually edit AI output?
Yes. Engineers can edit the generated flowchart manually, change nodes, add custom C/C++/ASM, configure events, and review the logic before building.
Does SmowCode provide source code and binaries?
Yes. Teams can download generated C source code, binaries, and build outputs for review, archive, and integration.
Do we need local installation?
For supported workflows, SmowCode runs in the browser with cloud build and flashing support, reducing local setup problems and compiler mismatch issues.
Which platforms are supported?
SmowCode supports ESP32, ESP32-S2, ESP32-S3, ESP32-C2, ESP32-C3, ESP32-C6, ESP32-H2, ESP8266, STM32F407xG, PLC14, and PLC38AR workflows. For more platforms, contact sales.
