Stop shipping apps.
Just text it.

Six AI agents that work entirely in iMessage: no download, no login, no new tab. Each runs on the Linq messaging API, with real blue bubbles, typing dots, tapbacks and screen effects.

The agents in action

Pick an agent. The phone plays its conversation the way the recipient would see it, and the code panel shows the Linq calls behind it.

Built by a squad, in parallel

Devin split the brief into six jobs and ran them all at once. Each subagent got one use case plus the Linq docs, and wrote the conversation and the code for it. Devin then reviewed the results and built this site around them.

    One endpoint to start

    Every agent above starts with the same call. Linq picks the best channel for each recipient (iMessage, then RCS, then SMS) so your agent never has to.

    curl -X POST https://api.linqapp.com/api/partner/v3/messages \
  -H "Authorization: Bearer $LINQ_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "to": ["+14155559876"],
    "message": {
      "parts": [{ "type": "text", "value": "hey, it\'s your agent 👋" }],
      "effect": { "type": "screen", "name": "confetti" }
    }
  }'
