Mantle Chat

Everything your team needs to work with AI together

Channels, shared AI sessions, calls, canvases, agents, automations, and company context — one workspace where people and AI move work forward together.

01

The right AI for the work

  • 60+ AI models

    Use models from OpenAI, Anthropic, Google, xAI, DeepSeek, and other providers with one Mantle subscription.

  • Switch models in context

    Move between GPT, Claude, Gemini, Grok, and DeepSeek without starting the conversation again or losing its history.

  • Web search with citations

    Search the live web from chat and follow cited sources back to the original pages.

  • Files, images, and voice

    Attach documents and images for analysis, or dictate a prompt when typing would slow you down.

  • Reasoning controls

    Choose the reasoning level on supported models and inspect reasoning summaries when they are available.

  • Edit, stop, and regenerate

    Refine a prompt, interrupt an answer, or regenerate it with the same model or a different one.

02

Conversation, made multiplayer

  • Channels with AI

    Keep project conversations in shared channels and @mention a model or agent whenever the team needs help.

  • Shared AI conversations

    Invite teammates into the same AI conversation so everyone sees the context and can ask follow-up questions.

  • Threads, mentions, and reactions

    Keep side conversations focused, notify the right people, and acknowledge updates without another message.

  • Direct messages

    Talk one-to-one or in groups, with the same files, AI mentions, threads, and calls available in channels.

  • Live presence and typing

    See who is online, who is viewing a conversation, and when a teammate is writing a reply.

  • Shareable conversations

    Publish a read-only AI conversation with a link, then manage every active share from one place.

03

Agents the team shares

  • Custom AI agents

    Give an agent a role, instructions, knowledge, tools, and the model that best fits its job.

  • Agent templates

    Start from a ready-made agent and adapt it to your team instead of configuring every workflow from scratch.

  • Agents shared with the workspace

    Create an agent once and give the whole team a consistent assistant with the same context and setup.

  • Agents in chats and channels

    Call an agent into the conversation where work is happening, then let teammates review and build on its result.

  • Tools with scoped access

    Connect only the apps an agent needs and control who can use or manage it inside the workspace.

04

Knowledge that stays useful

  • Collaborative canvases

    Write plans, briefs, articles, and internal documentation together in a rich, real-time editor.

  • Workspace knowledge base

    Add files and canvases to shared knowledge so AI answers with the same company context your team uses.

  • Workspace instructions

    Set shared guidance for terminology, policies, tone, and ways of working once at the workspace level.

  • Canvas version history

    Review earlier versions, see who contributed, and restore a previous snapshot when plans change.

  • Public canvas sharing

    Publish a canvas as a clean read-only page and revoke its link whenever it should no longer be public.

05

Calls that follow through

  • Calls in channels and DMs

    Start a voice call where the conversation already lives, without moving the team into another app.

  • Opt-in AI notes

    Turn on AI notes during a call when everyone wants a written record of what matters.

  • Decisions and action items

    Get a concise recap after the call with the key decisions and follow-up work separated out.

  • Messages to Linear issues

    Turn a message or follow-up into a Linear issue and keep a direct link between the discussion and the work.

06

Work that keeps moving

  • Manual and scheduled tasks

    Run an agent on demand or schedule recurring work for a daily, weekly, or custom cadence.

  • Event-triggered workflows

    Start a task from a channel message, webhook, or connected-app event instead of waiting for someone to ask.

  • Results delivered to channels

    Send digests, reports, and completed work back to the channel where the team can act on them.

  • Task history and run details

    Review past runs, outputs, timing, and failures so automated work stays visible and accountable.

  • 30+ connected tools

    Let agents read and act across tools such as GitHub, Linear, Slack, Gmail, Notion, Google Drive, and Stripe.

  • App updates in channels

    Route Linear, Notion, Stripe, and GitHub events into the channels that need to see them.

07

Everything in its place

  • Shared workspaces

    Separate teams, projects, and clients while keeping each workspace’s conversations, knowledge, and agents together.

  • Organizations and membership

    Invite teammates, manage workspace access, and organize multiple workspaces under one company.

  • Global search

    Search across messages and canvases to recover a decision, answer, or document without remembering where it lives.

  • Folders, pins, and archive

    Keep active work close, group related conversations, and move finished work out of the way without losing it.

  • Roles and permissions

    Control who can manage members, workspaces, agents, tasks, data, and shared resources.

  • Data export and shared-link controls

    Export your data and review or revoke published conversations and canvases from a central settings area.

08

Work from anywhere

  • Full web app

    Use the complete Mantle workspace in a browser on desktop or mobile without installing anything.

  • Native app for macOS

    Keep Mantle in a dedicated window with native notifications, signed builds, and built-in updates.

  • Bring your own coding subscriptions

    Run Codex, Claude Code, Cursor, OpenCode, and Grok CLI locally from the desktop app using subscriptions you already have.

  • Light and dark themes

    Match your system or choose the theme that keeps long work sessions comfortable.

  • Keyboard-first navigation

    Move through the workspace and reach common actions quickly with built-in keyboard shortcuts.

  • Windows, Linux, and mobile apps Soon

    Native apps for more platforms are on the roadmap; the web app works there today.
