Show HN: GlycemicGPT – Open-source AI-powered diabetes management
Not a pilot. A Type 1 diabetic engineer just open-sourced an AI platform that analyzes glucose data without leaving your hardware.
Why it matters
GlycemicGPT demonstrates a growing category of AI-powered health tools built with LLMs at the application layer—self-hosted, privacy-first, and designed to augment clinical decision-making rather than replace it. Shows how BYOAI architecture (Ollama, Claude, OpenAI endpoints) is enabling regulated use cases where data residency and audit trails matter.
The key facts
16 to knowSelf-hosted AI analysis layer for continuous glucose monitoring data
Supports Dexcom G7, Tandem t:slim X2/Mobi, Nightscout integrations
BYOAI model selection: Ollama (fully local) or Claude/OpenAI-compatible endpoints
Stack: FastAPI backend, Next.js dashboard, Kotlin Android/Wear OS apps
GPL-3.0 open source, no subscriptions, no vendor lock-in
Monitoring & analysis only—does not deliver insulin or control pumps
Data flows directly from self-hosted instance to chosen AI provider (no centralized service)
Plugin SDK available for community device support
Self-hosted platform; data never leaves user infrastructure unless explicitly routed to chosen AI provider
Supports Dexcom G7, Tandem t:slim X2, Mobi pumps, Nightscout via direct BLE or cloud API
BYOAI: users can run Ollama locally or bring Claude/OpenAI/compatible endpoints
Features: daily pattern briefs, meal response analysis, RAG-backed conversational chat, predictive alerting with caregiver escalation
Read-only monitoring—does not deliver insulin or control pumps (explicitly non-autonomous)
Stack: FastAPI, PostgreSQL, Redis, Next.js, React, TypeScript, Kotlin (Android/Wear OS)
GPL-3.0, no subscriptions, open-source on GitHub

Publisher excerpt: I'm a Type 1 diabetic and software engineer. Last year I went months between endocrinologists with no clinician reviewing my data. I'm an engineer, so I built the tool I needed — and now I'm open sourcing it. GlycemicGPT is a self-hosted platform that connects continuous glucose monitors, insulin…
