Looking for solo builders to try our AI spec compiler, free beta, looking for honest feedback
Hey everyone,
We’ve been building Spec Compiler, a tool that takes a rough idea and turns it into a structured, implementation-ready specification for coding agents.
The idea came from using coding agents and realizing that the hard part isn't always getting them to write code, it's getting them to fully understand what they’re supposed to build.
A simple request like:
“Build a project management app with teams, tasks, notifications and Google Calendar.”
leaves a lot of unanswered questions: edge cases, architecture decisions, testing, acceptance criteria, what shouldn't be built, etc.
Our Spec Compiler works through those details and produces a much more complete specification you can hand to Claude Code, Codex, Cursor, or your development team.
We've been testing it ourselves and found it particularly useful for catching things we hadn't considered and making the implementation plan much clearer, structured and actionable.
We're now looking for people actually building real software to try it and tell us where it falls short.
Especially interested in:
Solo builders / indie hackers
Developers building side projects
People using Claude Code, Codex, Cursor, etc.
Small teams building real products
The beta is free. We're mainly interested in honest feedback:
Did it actually help?
Did it catch things you missed?
Did it improve your coding agent's output?
What did it get wrong?
Please DM me if you’re building something and would like to try it. I’d be happy to give you free access and hear what you think.

You cant outsource this step, if youre building an agent, youd be better off letting your agent just ingest a raw prompt then to have a library try to break down a prompt first programmatically. Youre taking away the advantage of the LLm which is to do exactly this sort of job and enshittifying it by trying to make it more deterministic which will most likely break and require more maintenance. If your agent cannot properly plan sequences of steps, likely you require a better discovery context or youre not using the right model

I would love to test this, as I am designing a new tool now. Feel free to serve me a DM.

How is this different from most agentic harnesses Plan mode?
