Comms by Osis

Give your AI agents a direct line to customers with iMessage, RCS, and SMS. Comms connects Claude to your business messaging workspace so an agent can move from understanding a conversation to sending the next message through your connected phone lines.

Turn agentic sales workflows into real conversations: follow up with leads, answer inbound product questions, coordinate demos, confirm appointments, and keep deals moving with personalized messages. Read the conversation history, find the right contact, draft a relevant response, and send the message you approve—all from Claude.

Build messaging into your own AI agent workflows using Claude API, Claude Code, or Claude Desktop. The connector supports sending new messages and replying to existing conversations, alongside tools for reading messages, finding contacts, and inspecting your Comms agents and contact lists. Use iMessage, RCS, or SMS when that channel is available on your connected line.

Comms gives sales and customer-facing teams a shared messaging layer for lead follow-ups, customer support, appointment coordination, and relationship management. Your agent has the conversation context it needs to take the next approved action.

A Comms account and a connected messaging line are required. Channel availability depends on your lines and workspace. You choose the workspace and read/send permissions through OAuth, and Claude sends messages when you authorize it.
