Convos launches group-chat agents built from tagged posts

• Convos launched an agentic messenger where tagging @convosmessenger with a tweet, screenshot, or idea creates an agent, according to ShaneMac's launch post.
• Group chats can build their own agents and apps inside the thread, a capability ShaneMac described in a follow-up.
• The builder hides harness setup: ShaneMac said a post can become a Hermes agent in 60 seconds, free to try.
• The strongest demos are not chatbots: ticket buying uses Link and Browserbase in the live music demo, while trip planning produces maps and itineraries in the Portland example.
• Safety and sharing are scoped by group: ShaneMac's longer post says reused agents fork, persona travels, memory does not.

Convos is the rare AI launch where the weird details are the product. ShaneMac's live music post shows Link approval, saved cards, and per-purchase protected card numbers in the ticket-buying demo; his Agentmail post says agents expose email addresses on their profiles for forwarding travel emails. A Fable opsec tester appears in ShaneMac's group-chat video, and a ticket-data polling skill appears as a hermes skills install command in his Hermes reply.

ShaneMac framed Convos around one input: tag @convosmessenger with a tweet, screenshot, or idea, then get a small agent to use with friends. Every agent comes with a Hermes harness from NousResearch, according to the launch post.

The setup promise is blunt:

• No Botfather, from ShaneMac's launch post.
• No command line, from the same post.
• No Mac minis, from the same post.
• Build from an idea, screenshot, or post in 60 seconds, according to ShaneMac's Hermes builder post.
• Free to try with no sign-up required, according to ShaneMac's free-to-try post.

Access is public enough to have a builder link: ShaneMac's build-your-own link sits under a Broadsheet demo, and his release post simply calls it “Convos, The Agentic Messenger.” Model routing appears to run through OpenRouter, based on ShaneMac's reply saying it was “all built on Open router.”

Every group chat can now build its own agent inside the group, including apps for the group, according to ShaneMac's follow-up. That is the sharp bit: the group thread becomes the prompt, the workspace, and the distribution surface.

ShaneMac put the data advantage plainly in one reply: “The group chat is where the hardest to get data lives.” In his longer agentic-messenger post, he argued that group chats already hold the trip, the stalled decision, the preferences, and the people.

The live music agent in ShaneMac's demo monitors local venue websites, sends weekly show picks, and uses Browserbase under the hood to buy tickets through Link.

The Link connection screen in the same demo lists three payment mechanics:

• Make agentic payments with saved payment methods.
• Approve every spend with face or fingerprint.
• Hide real payment details behind a unique number for each purchase.

Ticketing also showed up at the Hermes skill layer. ShaneMac said polling was already built into Hermes in his reply about ticketdata, then gave a hermes skills install mvanhorn/printing-press-library/cli-skills/pp-ticketdata --force command.

Trip planning is the cleanest creator demo so far. ShaneMac's travel prompt says a city reply plus a Convos tag can build an itinerary and generate a custom travel app for the group.

The Portland demo in ShaneMac's planning post shows the app shape: a trip map, a shared “Things” list, place cards, directions buttons, and filters for coffee, food, and beaches. The “Get back to living” post adds the lightweight version, a Trip Scout chat that recommended blueberry pancakes in Portland and got followed in the real world.

Convos demos are already spreading across chores, briefings, and personal tools.

• Fable: ShaneMac's video shows a personal opsec pen tester running inside a group chat and generating security analysis.
• Scribe: his Scribe post says it builds weekly briefings of what personal group chats discussed, what people missed, and which ideas need follow-up.
• Homeostasis: ShaneMac's health-agent prompt fed Packy and Lenny health notes into Convos, and his follow-up said the resulting agent worked.
• Bryan Johnson coach: ShaneMac's prompt asked Convos to turn 41 Bryan Johnson tips into a daily coach, and his follow-up said it was free with no sign-up.
• Broadsheet: his Broadsheet post describes an agent that tracks everyone Patrick Collison links to and builds a daily newspaper from what changed.

The funniest Convos demo is debt collection. ShaneMac said in his payment-chasing post that he had used this group-agent pattern five times, including a trip chat where the agent acted like a college RA and kept nudging one person to pay.

The screenshot turns a familiar group-chat failure mode into a delegated social task: ask Jimmy for the money, confirm payment, let friends stay friends.

ShaneMac's longer Convos post gets closest to the system design. He said agent setup felt too much like explaining crypto in his harness setup post, then used Convos to hide the harness behind a tag.

The core model in his agentic-messenger thesis has five parts:

• Agents sit in group chats where context already exists.
• Agents talk when they have something to say, otherwise they work quietly.
• Dropping an agent into a group adds it to everyone's contacts.
• Reusing an agent forks it: the persona travels, the memory does not.
• Every remix gets its own harness, memory, context, data connections, and frontier models.

The permissions model is group-scoped. ShaneMac's post says nothing crosses groups, and every data connection is per agent, per group, and chosen by the user.

Agent choice is still forming. In a reply about opt-in agents, ShaneMac said agents are opt-in and Convos is exploring bring-your-own agents so users can invite their own.
