The unseen infrastructure for modern inventors.
Invisra builds review-first software tools for builders, makers, hardware engineers, and software engineers who want practical outputs instead of open-ended prompt roulette.
Core principle: predictable workflows, human approval, useful artifacts.
A specification JSON schema for practical, parametric 3D/CAD parts.
- Repo: https://github.com/invisra/printspec
- Schema: https://schemas.invisra.ai/printspec/
- Outputs: OpenSCAD, CadQuery, BOM, and drawing metadata
- Status: active development
An open source JSON schema for defining a business plan.
- Repo: https://github.com/invisra/open-business-plan
- Status: active development
Invisra develops AI-assisted engineering tools along with the schemas, workers, and supplier integrations behind them. Most of that work lives in private repositories today — the open building blocks above are the pieces we publish as they stabilize.
Pragmatic hardware/software automation for real constraints.
- Predictable over flashy
- Human approval where it matters
- Reliable under real use
- Useful artifacts, not just chat
