OPERATING PLAYBOOK

One workflow, four accountable stages.

01PE
Research AI

Perplexity

Research the market and preserve source links.

One of the quickest ways to move from a broad question to a source trail, provided the buyer still opens and checks the cited material.

02CG
Text AI

ChatGPT

Turn evidence into a narrow product scope.

Why it is here
The strongest general-purpose AI counter for broad daily use, especially when writing, analysis, coding and image understanding need to live in one place.

Free tier
03LO
Web AI

Lovable

Build and test a working prototype.

Why it is here
A strong visual product builder for founders who need a credible prototype quickly and understand that generated code still needs ownership and QA.

04CA
Marketing AI
