Not another app. A phone number. Works in your existing group chat. iMessage, Android, mixed — doesn't matter.

Silence is the default. Plus1 only speaks when you ask, or when something you asked it to remember comes due. Reply STOP anytime, in any group, forever.

FAQ

So is this AI?

Under the hood, yes — we use a small language model to figure out what you're asking for. But the product is the apps. Silence is our default, personality is not the pitch, and we never ask you to "chat with an AI."

What can I say to it?

Anything the apps can do. "fri vs sat?" starts a poll. "what did we decide about the reservation" hits memory. "remind us at 2pm" is a nudge. "find good ramen near us" kicks off a search.

Who is this for?

Friend groups that already text each other and need a little help following through. Not teams, not customers, not communities.

What does it cost?

Plus1 is free during the beta. Msg & data rates may apply from your mobile carrier.

a note on privacy. your group's context stays yours. we don't store phone numbers. switch who's in the group, the bot forgets. built to minimize what could ever be disclosed. the first thing Plus1 does in a new chat is introduce itself — anyone can reply STOP anytime. read the full model →
