Overview
Mantle Chat is an AI-powered collaboration platform that puts your team and 60+ AI models into one shared workspace. Instead of every teammate running private ChatGPT or Claude conversations in isolation, Mantle gives you Discord/Slack-style channels and DMs where any team member can @-mention models like Claude Opus 4.6, GPT-5, Gemini 3 Pro, Grok, or DeepSeek into the conversation. Conversations, knowledge, and AI outputs accumulate as shared team context rather than disappearing into individual chat histories.
Beyond chat, Mantle layers in shared AI agents (custom instructions + knowledge bases + scheduled tasks), 30+ tool integrations (Notion, Linear, Gmail, GitHub, Stripe and more), and automation workflows that can be manually run, scheduled, or triggered by tool events. It positions itself as a single workspace for the "AI agent" wave — sitting where Slack/Discord, AI chatbots, and tool automation overlap. Mantle Chat had its second Product Hunt launch on May 19, 2026 (Day Rank #4, 344 upvotes), following its original Open Beta launch in November 2025.
Key Features
- 60+ AI models in one chat —
@-mention Claude (including Opus 4.6), GPT (including GPT-5), Gemini (including 3 Pro), Grok, DeepSeek, and dozens of others mid-conversation without leaving the workspace; usage still depends on Mantle's plan allowance and model cost tier. - Team channels, DMs, and groups — Discord/Slack-style structure with real-time messaging, so AI usage happens alongside normal team communication instead of in a separate browser tab.
- Shared AI agents — Build agents with custom instructions, attached knowledge files, and scheduled tasks; anyone on the team can use or fork them rather than rebuilding the same prompt repeatedly in private chats.
- 30+ tool integrations — Connect Notion, Linear, Gmail, GitHub, Stripe, and other team-stack apps so agents can read context and perform actions instead of only generating text.
- Automation workflows — Run agent tasks manually or on a schedule, and use event-triggered workflows where supported (verify specific tool-event triggers such as a GitHub PR review agent with Mantle before treating them as fully available).
- Shared knowledge base — Upload documents and let any AI model in the workspace use them as context, building team-wide memory instead of per-user knowledge silos.
Integration Guide
Mantle is designed to be the layer where your team's existing tools talk to AI — not a replacement for them.
- Communication & docs — Notion for shared documentation context; Gmail for inbound email triage and outbound drafting from inside the chat.
- Engineering — GitHub for code context, PR review agents, and issue automation; Linear for ticket sync and status routing.
- Operations — Stripe and other ops-stack tools so agents can answer revenue or billing questions with live data rather than stale screenshots pasted in.
- AI model coverage — 60+ AI models reachable by
@-mention; on the Pro tier this includes premium models like Claude Opus 4.6, GPT-5, and Gemini 3 Pro that are normally gated behind individual paid subscriptions.
Confirm specific integration availability with Mantle if you depend on a particular CRM, scheduling, or data source that isn't in the standard 30+ list.

Team collaboration is not Pro-only — every plan supports unlimited workspaces, members, and invites. Team mainly adds organization-level billing, centralized seats, member management, billing controls, and SAML/OIDC SSO availability for 30+ seats. Confirm exact per-seat invoicing terms on Mantle's official pricing page.
Best For
- Small teams paying for two or more individual premium AI subscriptions per person who want to consolidate into a single workspace.
- Product, design, and engineering teams that want AI agents tied to GitHub, Linear, and Notion sitting in the same chat as the team conversation.
- Operations and support teams running scheduled agent tasks, recurring reports, and supported event-triggered automations (verify exact integration and trigger coverage before depending on it).
- Teams that want to compare model outputs (Claude vs GPT vs Gemini) on the same prompt without switching tabs.
- Founders and startups already invested in AI productivity tooling who want a single AI-native communication layer instead of bolting AI onto Slack.
FAQ
What is Mantle Chat?
Mantle Chat is a Discord/Slack-style team workspace where any team member can @-mention 60+ AI models (Claude, GPT, Gemini, Grok, DeepSeek and others) into shared conversations, build shared AI agents, and connect 30+ tools like Notion, Linear, Gmail, GitHub, and Stripe.
How is Mantle Chat different from using ChatGPT or Claude separately?
ChatGPT and Claude are personal AI chat tools. Mantle adds three things on top: (1) team-shared conversations and channels, (2) shared agents with knowledge files and scheduled tasks, and (3) tool integrations so agents can act on Notion, Linear, GitHub, etc. The whole team builds on the same AI context rather than each person running their own thread. For a broader comparison of standalone options, see our best AI chatbots guide.
How much does Mantle Chat cost?
Mantle Chat is freemium. The free tier is $0 with a light allowance that refills every 5 hours and access to Low/Moderate cost models. Pro starts at $10/month (annual billing) and includes heavier usage, Monthly Reserve, premium-model access (Claude Opus 4.6, GPT-5, Gemini 3 Pro), unlimited chat history, web search, and 20MB file attachments. Team starts at $13/user/month (annual). Pro comes with a 7-day free trial.
Which AI models does Mantle Chat support?
Mantle Chat supports 60+ models, including Claude (Opus 4.6 on Pro), GPT (GPT-5 on Pro), Gemini (3 Pro on Pro), Grok, DeepSeek, and others. You @-mention them inside a conversation rather than switching tools.
What tool integrations does Mantle Chat have?
Mantle Chat connects to 30+ tools including Notion, Linear, Gmail, GitHub, and Stripe. Agents can read context from these tools and trigger actions through them. Confirm specific integration availability with Mantle if your stack needs a particular CRM or data source.
Can Mantle Chat replace Slack or Discord for my team?
It can if AI-augmented conversation is the main thing your team wants from chat. Mantle gives you channels, DMs, and groups, but its design is centered on shared AI context, agents, and automations — not on the extensive bot ecosystem, voice/video features, or compliance posture of mature team-chat platforms.
Are team workspaces available on the free tier?
No. Mantle states every plan supports unlimited workspaces, members, and invites. Free users get a light allowance and Low/Moderate cost models, while Pro and Team add heavier usage, frontier-model access, web search, and (on Team) organization billing/admin capabilities.
Is Mantle Chat new?
Mantle Chat first launched in Open Beta on November 13, 2025 and had its second Product Hunt launch on May 19, 2026, hitting Day Rank #4 with 344 upvotes. It is still a relatively new platform compared with mature team-chat suites.
