Tredict alternative: garmlink compared

If all you want is for an assistant such as Claude, ChatGPT or Gemini to read your Garmin history, garmlink does that for free, with nothing to install. If you want the assistant to send training plans and workouts to your watch, or a whole training platform, Tredict is the better choice: it is an official Garmin partner, and garmlink never writes to Garmin.

Claude, ChatGPT, Codex, Grok, Perplexity and Le Chat.

garmlink

Price
Free.
Assistants
Claude (Free plan included), ChatGPT (developer mode, on paid plans), Perplexity (Pro and above), Le Chat and Grok; Gemini through custom apps in the Gemini app (US for now) or the Gemini CLI; and code tools such as Cursor, Codex, Claude Code and VS Code.
Access to Garmin
Your Garmin sign-in, used once: the password is never stored, and the access tokens are kept encrypted. Not a Garmin partner.
Writes to Garmin
No. It never posts to Garmin and never modifies your account.
Worth knowing
Your past data is synced ahead of time and kept up to date, so an assistant can answer over weeks and months, not only about today.

Choose Tredict if

  • You want the assistant to send training plans and workouts to your watch.
  • You want an official Garmin partner, linked through Garmin’s own sign-in page.
  • You want a complete training platform, of which the AI connection is one part.

Choose garmlink if

  • You only want your assistant to read your Garmin data, for free: Tredict’s AI connection needs its full access, $49 a year after two free months.
  • You use Gemini, or a code tool such as Cursor, Claude Code or VS Code, none of which Tredict’s page lists.
  • You want nothing to set up beyond the connection itself: one address in your assistant, one Garmin sign-in.

Can you use both?

Usually, yes. An assistant can hold several connectors at once, and garmlink only reads: it changes nothing in your Garmin account, so you can keep Tredict linked while you try it and compare the answers. The exception is Claude’s Free plan, which allows a single custom connector: there you swap one for the other, or move to a paid plan.
