Just talk, and the apps your group or friends needs appear in the chat. "We're 4 friends training for a marathon, build us a tracker" becomes a real app: leaderboard, streaks, a $500 pot, and the AI poking whoever skips a run. Shared software, generated on the fly: native iOS UI, one live state for the whole chat, zero setup. Full-blown social apps, not widgets. We're starting with fitness. A real messenger. Free.
Inline is a thread-based chat app for all work, with your team and agents.
GhostReply is an AI auto-replier for iMessage that runs in Terminal on your Mac. It learns how you text each person, watches only the conversations you choose, and replies in your style. This release adds hosted AI, so there is no API key to create. Try 10 replies free, then pay $4.99 once.
Your agent can deploy in seconds but cannot get a phone number. Dial fixes that - one API call and it gets a real one in about 10 seconds. It places and receives voice calls, sends and receives SMS in 200+ countries, and messages over iMessage. It can even read inbound verification codes, so phone-gated signups stop being a dead end. Works via REST API, CLI, MCP servers, and SDKs. Free credit on signup, no card.
OpenClaw 2.0 simplifies setup by detecting ChatGPT or Claude keys automatically and lets configuration happen through chats with the agent itself.

Build one customer-facing AI agent and launch it across SMS, iMessage, WhatsApp, Slack, Telegram, and email.

Keiki runs the shared infrastructure behind every channel and gives you one place to inspect conversations, approve sensitive actions, and improve the agent over time.

Big Mike reads MLB, NFL/CFB, and NBA/WNBA all day and texts you the play in iMessage: what to bet, at what number, and which book has it. July Record: 115-68, +21.4 units.

Fair warning: he stirs up banter. Link your Sleeper or ESPN league and the start/sit calls are about your roster. Ask Big Mike.
