Feasibility in Plain Language
Connect your AI assistant so you can prompt buildable outcomes that are directly editable in TestFit.
Generate Results with a Simple Prompt
Direct the AI Assistant of your choice and TestFit will produce the result. No hallucinations, only buildable outcomes.
- Direct the engine in plain language and run more iterations in less time
- Generate every result with the same deterministic engine that runs your studies today
- Keep working in TestFit with the AI assistant you already use; no new interface to learn.
Prompt and Edit, in Either Order
Prompt, watch it generate, adjust it by hand, then keep prompting from where you left off.
- Edit one live model every time you prompt, so nothing needs re-importing or reconciling
- Switch between conversation and manual controls mid-study without losing your context
- Get to a workable study faster by prompting the first pass and refining from there
Frequently Asked Questions
What is the MCP connector?
It lets you drive TestFit from the AI assistant you already use. You prompt in Claude, ChatGPT, or whatever you've got open, and TestFit does the work and sends back real site plans, geometry, and numbers.
Do I need to bring my own AI?
Yes, and that's the point. You pick the assistant. TestFit doesn't supply one, embed one, or push you toward one. Your assistant just gets a way to talk to TestFit.
Is the AI designing my building?
No. Your assistant handles the conversation. TestFit's engine does the design, running on the same proprietary algorithms it always has. Same inputs, same outputs, every time. Nothing is guessing at your yield.
Does TestFit see my prompts or train on my data?
No to both. Your prompts and conversation history stay with you and your AI provider. And TestFit has no model to train, because the product runs on deterministic algorithms rather than an LLM. There's nothing on our side ingesting your designs.
Does anything change about how I use TestFit?
No. This is an additional way in, not a replacement. Every workflow you have in TestFit today works exactly as it did yesterday.
Direct TestFit with the AI Assistant You Trust
Connect the assistant you already use and get back the same defensible, engine-generated results.
