From idea to working product
in one conversation
3dot5 validates your product idea with live market research, then generates an autonomous build plan that your AI IDE executes end-to-end. No coding required.
Three steps. Zero friction.
Describe what you want to build. 3dot5 handles everything else.
Describe your idea

Founder & Creator
I built 3dot5 because I became convinced the real bottleneck in software is no longer writing code. It is deciding what should exist in the first place.
For most of my career I've worked at the intersection of AI, configuration systems, and digital commerce experiences, helping companies turn complex ideas into real digital products. The process was always slow: research, specs, tickets, sprints. Weeks or months before you even knew if the idea was worth building.
AI changed that.
Today, tools like AI-assisted IDEs can build real applications in hours. The gap between intent and execution is disappearing. But that reveals a new bottleneck: the thinking before the code. Understanding the market, identifying real opportunities, and designing the right product.
3dot5 automates that part.
You describe an idea. The system analyzes the market, finds opportunity gaps, designs the product strategy, and produces a build specification your AI tools can turn into a working product.
Because the developer's job used to be writing code.
The creator's job is deciding what should exist.
3dot5 is built for creators: people with ideas, judgment, and vision. If you have something you believe should exist in the world, this is your invitation to bring it to life.
Frequently asked questions
A complete, self-executing Markdown file with every instruction the AI IDE needs: tech stack decisions, install commands, full database schemas, authentication flows, API endpoints with complete TypeScript interfaces, page-by-page UI specifications with full component code, styling system, development phases, and deployment steps. Every code block is complete -- no placeholders, no TODOs.
No. 3dot5 generates an autonomous build specification. You download it, paste it into an AI-assisted IDE like Cursor, and the IDE's AI agent builds the entire application. You just need to create accounts for the services your app uses (the build plan tells the AI to guide you through that too).
We recommend Cursor (cursor.com) as the primary choice. It has the most advanced AI agent mode for executing build plans autonomously. Windsurf and GitHub Copilot are alternatives that also work.
Every analysis uses real-time data -- not stale training data -- to identify competitors, market trends, and pricing models. The research is compressed and verified before synthesis.
Free gives you 3 analyses per month with a basic market snapshot. Build Test ($10 one-time) lets you generate one full blueprint to try it out. Pro ($29/month) gives you 10 full blueprints per month with unlimited analyses. Power ($79/month) gives 50 blueprints per month with priority processing. Annual plans save you 2 months.
Yes. Every section has an inline editor. You can modify the content and submit your edits back to 3dot5, which uses AI to refine the section based on your feedback.
3dot5 uses a proprietary multi-model pipeline optimized for speed and depth. Each stage of the analysis uses the best model for the job.
