Inline

Inline is a thread-based chat application built for multiplayer work, designed to bring teammates and AI agents into the same collaborative space. It is currently available in beta for macOS and iOS, with other platforms described as coming soon. The project is developed by the Inline team and offers CLI, MCP, and agent plugin integrations alongside its native apps.

What It Is

Inline positions itself as "the interface for multiplayer work" — a thread-based messaging tool that blends human team communication with AI agent participation. Rather than treating AI as a bolt-on feature, Inline is built from the ground up to support agents as first-class participants in conversations alongside human teammates. The app targets teams that want a unified workspace where both people and autonomous agents can collaborate in real time.

Platform Availability

Inline is currently in beta, with native apps for macOS and iOS (via TestFlight). The homepage notes that other platforms are coming soon. In addition to the native apps, Inline provides:

• A CLI for terminal-based access
• MCP (Model Context Protocol) integration for connecting AI models
• Agent plugins for extending agent capabilities within the workspace

Agent and AI Integration

A core differentiator of Inline is its first-class support for AI agents. The platform includes dedicated documentation for setting up agents, and ships with two named agent integrations: OpenClaw and Hermes Agent. The MCP integration allows AI models to interact directly within Inline threads, making it suitable for teams building or deploying AI-assisted workflows. The GitHub organization (inline-chat) suggests active open development around these agent capabilities.

Workflow and Use Cases

Inline is thread-based, meaning conversations are organized into discrete threads rather than a flat channel model. Screenshots on the homepage show use cases such as discussing message styles, composing messages, reviewing workspace overviews, and examining Sentry reports — suggesting it is aimed at software development and technical teams. The integration with tools like Sentry points toward a developer-focused audience that wants to bring operational context directly into team chat.

Current Status

Inline is in active beta as of 2026. The iOS version is available via Apple TestFlight, and the macOS version is available for direct download. The homepage changelog ("What's New") and a YouTube announcement video titled "Announcing Inline Beta" confirm the product is in an early but publicly accessible stage.
