LoopedTune reads glucose, treatments and profile from your Nightscout site and reports what it finds. It does not write to your site and does not store your access token. To look for patterns beyond the fixed checks, an hourly summary of your glucose for the period (no name, no site address) is sent to Anthropic's API; the results are re-checked against your data before they are shown. LoopedTune is not medical advice. Discuss settings changes with your care team.

Open source. Self-host it. Successor in spirit to AutotuneWeb, which was retired in 2026.
