AI Chat

OpenCharts AI Chat is Theo, a conversational AI assistant with 11 specialized modes (Fast, Think, Research, Code, Voice, Consensus, Image, Video, Social/Calendar, Learn, Explore) that answers questions, brainstorms, and creates real projects — flowcharts, whiteboards, notes, presentations, podcasts, code, and more — from a single prompt.

Getting Started

Open Chat from the sidebar (the sparkles icon at the top). Type your message or pick a quick action pill, then press Enter or click send.

Each conversation is automatically saved so you can return to it later via the chat sidebar on the left.

Theo in the Sidebar

On non-chat pages, Theo can appear directly in the sidebar as a small interactive companion. Click Theo to open quick actions like jumping into chat, getting a quip, or starting the intro experience.

Choosing Theo the Movie launches a short cinematic intro where the room dims, Theo moves from the sidebar to center stage, and the presentation is projected onto the screen.

Press Esc to close the intro at any time. If your system prefers reduced motion, OpenCharts automatically shows a simpler version of the sequence.

Model Modes

Switch between three modes using the toggle pills above the input. Each mode uses a different AI model optimized for different tasks.

Fast

Theo Fast — quick answers, brainstorming, simple edits.

Think

Theo Think — deep reasoning, complex analysis, detailed plans.

Image

Theo Imagine — generate images, illustrations, logos, and visual content from text prompts.

Creating Projects via Chat

The AI can create real OpenCharts projects from your prompts. Just describe what you need and the AI will generate it with nodes, edges, slides, or rich text — then give you a link to open it.

Flowcharts

Describe a process and the AI generates a complete flowchart project.

Whiteboards

Ask for mind maps, wireframes, or brainstorm boards.

Notes

Request meeting notes, summaries, or documentation — created as a Notes project.

Presentations

Outline a topic and get a slide deck with titles and bullet points.

Image Generation

Switch to Image mode (the aperture icon) to generate images with Theo Imagine. Simply describe what you want and the AI will create it directly in the chat.

What you can create

  • Photos, illustrations, and artwork in any style
  • Logos, icons, and branding assets
  • UI mockups and wireframes
  • Multiple variations in a single response ("create 4 options")
  • Iterative edits ("make the background darker", "add a border")

Working with generated images

  • Copy — hover over an image and click Copy to add it to your clipboard
  • Download — save the image as a PNG file
  • Import — add the image directly into a Notes, Flowchart, or Whiteboard project
  • Expand — click any image to view it full-screen

You can also generate images from Fast or Think mode — the AI will use the generate_image tool to create images without switching modes.

Inline Tables

Ask the AI to "create a comparison table" or "list features in a table" and it will render a structured table directly in the chat. These are displayed inline — no separate project is created.

Sharing Code Artifacts

When Theo generates a code artifact in Code mode, you can share it with anyone using a public link. Click the Share button in the code preview panel or on the inline code card.

The share link opens a branded preview page where recipients can see the live output and browse the source code — no account required.

Conversation History

All conversations are saved automatically. The sidebar shows your recent chats grouped by time. Click any conversation to resume it.

You can delete conversations from the sidebar using the trash icon on hover.

AI Credits

Chat uses your AI credit balance. Think mode uses more credits per message than Fast mode due to the larger model. You can check your remaining credits in Settings → Billing.
