01 / FREEDOM TO COMBINE

Switch the intelligence.
Keep the train of thought.

The model you want planning isn’t always the one you want building. In Maestrly, you choose both — in the same conversation, with the same context.

  • Quick provider and model switching
  • History, plan, and context stay together
  • You decide who takes the next step

IN THE LEADFable
01

Fable prepares the plan and sends it to the Plan tab.

Task planPlan
  1. 01Structure the project workspace
  2. 02Connect the existing navigation
  3. 03Implement the new interface

Same plan. Same history. Same conversation.Automatic walkthrough

02 / CONTINUITY ACROSS ACCOUNTS

The quota ends.
The work continues.

Connect multiple accounts from the same provider. When one reaches its limit, the next available account takes over.

INTERACTIVE EXAMPLE · SIMULATION

Example with two Codex accounts. Quotas and availability depend on the provider.

03 / MAESTRO MODE

You choose the team.
Maestro conducts.

Define your orchestrator and subagent profiles. It delegates each task according to the capabilities you configure — including across different providers.

A GPT model can call Sonnet. Opus can delegate to Luna. Every profile has its own role, instructions, and tools.

04 / TOOLS IN THEIR PLACE

One shortcut. Your tool.
Esc. Back to the conversation.

Open VS Code, check the terminal, and see your project in the browser. All inside Maestrly, without losing your train of thought.

Each conversation keeps its own tool environment.

VS Code, right in front of you.

What happens in the recording
  1. The same conversation stays open in Maestrly.
  2. Control + Command + E opens VS Code with the project code. Esc closes the panel.
  3. Control + Command + J opens the terminal with a real project command. Esc returns to the conversation.
  4. Control + Command + B opens the browser with the local page. Esc closes the panel, leaving the conversation in place.

06 / CHATGPT COMPANION Beta

Your ChatGPT web.
Part of your workflow.

Bring ChatGPT web closer to your code. It can access the project, use MCP, see the browser, and send plans to your agent in Maestrly.

Use ChatGPT web quotas, separate from Codex quotas.

Illustrative connection

ChatGPT web prepares the plan; your Maestrly agent receives it and continues the work.

Companion is in beta. Access depends on pairing and granted permissions.

BEFORE YOU START

Your accounts.
Your choices.

Is Maestrly free?

Yes. The app is free and open source under the MIT license. Bring your own accounts or API keys; provider costs and limits still apply. Contributions are optional.

Can I combine models from different companies?

Yes. You can switch providers in a conversation and configure subagents from other providers. Available models and features depend on connected accounts and granted permissions.

What stays on my computer?

Workspace state stays on your device. Your chosen providers receive the context needed for each task. Tools follow your configured permissions.

Are these demos connected to an AI?

No. All interactions on this page are local simulations. App images are real Maestrly screenshots; diagrams explain workflows and do not reproduce Maestrly screens.
