Can you vibecode this?

Yes

The core loop — take text or image input, call AI image generation APIs, post-process for patent-office compliance, and export — is pure code. Auth, credits, versioning, and multi-office formatting rules are all buildable by one person.

Why people pay PatentFig

PatentFig has built compliance logic for USPTO, EPO, CNIPA, JPO, KIPO, and PCT formats, plus version history and project organization that accumulates per patent application. A fresh copy starts with none of that filing-specific compliance tuning or a customer's existing project history.

Product complexity
Moderate
AI figure generation with multi-office compliance, version control and chat-based editing requires substantial product depth.
Data
Low
Customers supply their own sketches, photos and descriptions; no external data source is required.
Integrations & infrastructure
Low
No named third-party integrations beyond Stripe are required to run the core product.
Human operations
Low
Generation, versioning and export are fully automated; no human delivery step is involved.
Regulation / hardware
Low
Patent figure formatting rules are public standards, not a license the business must hold.
