Desktop app (Mac, Windows, Linux) where AI agents plan, build, test and deploy your product
Basic · $16/mo
+ Your own AI plan (Claude, ChatGPT or Grok) ~$20/mo
Why: Several AI agents plan, build, test and deploy the features in parallel — the closest thing to a small dev team, on your own AI subscription.
Best for: Solo founders shipping a real multi-feature product who want several agents working in parallel. Not for: Engineers who only want smarter autocomplete in their current editor.

Build steps with BridgeMind
- 1Write a one-paragraph brief for an AI chatbot: who it's for, the 3 core screens, and what people pay for.
- 2Pick a model and cap spend: Claude Haiku 4.5 costs $1 per million input and $5 per million output tokens — about $0.003 for a typical chat.
- 3Install BridgeMind (Mac, Windows or Linux), connect your AI subscription — for example Claude Pro — and create the project.
- 4Let the agents turn the brief into a task plan, and approve the plan before they build.
- 5Run agents in parallel on separate features — for example one on sign-in, one on the main screen.
- 6Review each change in the preview and request fixes the way you'd brief a contractor.
- 7Deploy to Railway (Hobby $5/month includes $5 of usage) and add your domain.
- 8Put it in front of five real users before adding more features.
What the first version includes: Chat widget or page · Answers grounded in your docs · Conversation log · Hand-off to a human.
Your build brief
Paste it into BridgeMind as your first message — it already knows the scope, the stack and your budget.
Build the first version of an AI chatbot: [your idea in one sentence — e.g. a support assistant that answers from our help docs]. This version includes: - Chat widget or page - Answers grounded in your docs - Conversation log - Hand-off to a human Tech and services: - Store data in Postgres (on Railway or Supabase). - Answers from Claude Haiku 4.5 via the Anthropic API, grounded only in the documents I give you, with a spending cap per conversation. - Deploy on Railway, with every secret in environment variables. How to work: - First turn this brief into a task plan and show it to me before writing any code. Split the work so separate agents can build "Chat widget or page" and "Answers grounded in your docs" in parallel, and give me a one-line summary after each task. - Build only what is listed above; ask me before adding anything else. - Keep tools and hosting under about $48 a month and aim for a working prototype in a weekend.
