Launch brainstorm

Interactive demo

Help me plan a launch for my new product.

GPT · OpenAI

Start with one audience and one problem. Build a small demo that shows the value, then gather feedback before scaling.

Same thread, new model

How would you improve this plan?

Claude · Anthropic

Make the idea easier to understand. Lead with the problem you solve, show one useful workflow, and give people a clear next step.

Who replies next? Context carries over.

Sample replies · no API calls Context kept

Pick a model to see a different sample reply. No API key needed for this demo.

Why one workspace

Stop restarting chats to get a second opinion.

Ask another model to check an answer or suggest a different approach. Keep the conversation instead of explaining everything again.

01

Switch models mid-thread

Start with GPT, then ask Claude for a second opinion. No need to copy the conversation into another app.

02

Your keys stay yours

Your API keys are encrypted in this browser. Remove a connection or revoke a key whenever you want.

03

One fee. Zero markup.

Control comes standard

Your keys. Your call.

Your keys and chat history stay in this browser. Requests are processed through our server. Clearing site data can remove saved keys and chats.

How we handle your data

  • Encrypted at rest

    Keys are encrypted in this browser’s vault. They are decrypted when needed to process your request.

  • Processed through our server

    Your key and conversation go through our server to the provider over an encrypted connection. Requests are not sent directly from your browser to the provider.

  • You control access

    Delete a provider connection to remove its saved key from this browser. Revoke the key at the provider to stop access wherever it is used.

From first reply to your own models
