ComIO.Studio is a cross-platform desktop application that combines a feature-rich serial terminal with an intelligent AI assistant. Debug embedded systems, program microcontrollers, and analyze serial data — all in one tool.
ComIO.Studio is a professional desktop application for engineers, makers, and embedded developers who work with serial (UART/RS-232) devices every day. It replaces multiple tools — serial monitor, protocol analyzer, firmware flasher, and debugging assistant — with one unified application enhanced by artificial intelligence.
Whether you're debugging an ESP32 over UART, flashing firmware to an STM32, automating test sequences with Lua scripts, or decoding an unknown protocol — ComIO.Studio gives you everything in a single window, on any operating system.

Full port configuration — baud rate, parity, data/stop bits, flow control. Real-time RTS, DTR, DSR, CTS, DCD, RI line monitoring.
Built-in AI that understands your serial data context. Ask questions, get protocol analysis, decode hex payloads, troubleshoot connections.
Configurable data buffer, ASCII/HEX encoding, search, timestamps. Connection statistics — RX/TX bytes, uptime, reconnections.
Flash firmware to ESP8266, ESP32, STM32, and AVR microcontrollers directly through the serial port (UART). No external programmers or tools needed — just connect via USB-to-serial and flash.
Quick-access macros (M1–M6) for frequently used commands. Automatic triggers with pattern matching for hands-free automation.
Native performance on Linux, Windows, and macOS. Small footprint, fast startup, system-level access.
The serial terminal is free. The AI assistant is available through affordable subscription plans and can help you with:
Paste raw hex data and AI identifies the protocol (Modbus, NMEA, AT commands, custom), decodes fields, and explains the structure.
AI sees your port config and terminal output. Ask "why is my device not responding?" and get actionable suggestions — baud mismatch, wiring, flow control.
Generate ready-to-use Lua automation scripts, AT command sequences, Modbus queries, or C/Python code snippets for your specific device.
Feed sensor readings, GPS coordinates, or telemetry frames — AI parses, converts units, spots anomalies, and summarizes trends.
Ask about chip registers, AT command syntax, baud rate calculations, or CRC algorithms — instant answers without leaving the terminal.
Having trouble flashing firmware? AI analyzes error logs, suggests boot mode wiring, identifies flash size mismatches, and guides you step by step.
The serial terminal is free. AI plans start at $3/month.
