Mantle Chat is an AI-powered platform that brings together multiple AI models (OpenAI GPT, Anthropic Claude, and Google Gemini), private and shared workspaces, and team collaboration features— all in one ultimate platform.

Main features

We built Mantle Chat around three simple ideas: use any AI model without switching platforms, organize your work in unlimited workspaces, and collaborate with your team in real-time. These three features are what Mantle Chat is about—bringing everything you need into one place that works the way you do.

1. Multiple AI Models in One Place

Access GPT-5, Claude Sonnet 4, Gemini 2.5 Pro, and more without switching platforms. Every chat conversation lets you choose which AI model to use from the model dropdown.

Switch between models mid-conversation while maintaining context—compare how different models answer the same question without retyping your prompt.

Key capabilities:

• Model Selection: Choose from GPT-5, Claude Sonnet 4.5, Gemini 2.0 Flash, and more

• Quick Search: Find specific models by typing the model name, provider, or capability

• Smart Model Selector: See key information about each model—capabilities (Reasoning, Web Search, Image Analysis, Documents), what it's best for, and knowledge cutoff dates

• Customize Your Models: Manage which models appear in your selector via settings

2. Workspace Organization

Create unlimited workspaces to organize AI conversations by project, team, or topic. Each workspace keeps its own separate folders, threads, and settings.

Two types of workspaces:

• Private Workspaces: Your own workspaces for personal projects, learning, and notes

• Shared Workspaces: Collaborate with your team on development, planning, and documentation

Keep personal and work content completely separated with folder-based organization within each workspace.

3. Collaboration Tools

Share AI conversations with team members and collaborate in real-time. Work together seamlessly with live updates.

Collaboration features:

• Real-time Sync: Instant message delivery with presence indicators and typing status

• Share Links: Secure, time-limited access links for sharing conversations

• Team Presence: Live activity tracking showing who's active, viewing, or typing

• Team Channels: AI-powered channels where AI acts as an assistant or agent for projects
