Build an AI-powered
income stream.
Earnkit is the curriculum from a real 5-SaaS portfolio that ships every week. Every module is a playbook we actually built — with the prompts, the code, and the gotchas that cost us real time.
Free newsletter · Workshop $97/mo · Cohort $497 one-time
Five playbooks. All from shipped products.
Each module is a teardown of how we built and ship a real product in our portfolio. No theory-only courses. No fake screenshots.

Get one real playbook a week.
We ship every week. Every Friday you get the receipts — what we built, the prompts we ran, what broke, what worked. Unsubscribe in one click.
Honest answers.
Is this another 'make $10k/month with AI' grift?
No. Earnkit's curriculum is drawn from products we actually built and shipped — every module cites the real PRs and the real codebase. No income screenshots. No fake testimonials. The proof is the 5 live products linked above.
Do I need to know how to code?
Some modules (AI Storefronts, AI Productized Services) you can ship without much code — they're framework + prompts + workflow. Others (AI Voice Operations, AI Outbound) require some engineering. Every module is honest about the build complexity up front.
When does Cohort #1 start?
TBD — operator confirms a date before sales open. We'd rather start late with the right curriculum than launch a half-baked cohort. Join the waitlist at /cohort and you'll get a 48-hour head-start on enrollment when dates are set.
What's in the free tier?
The weekly newsletter, lesson 1 of all 5 modules (the honest portfolio teardown — what we built and why), and the public prompt library. Lessons 2-6 unlock with Workshop. Lessons 7-9 (the Cohort-tier operational artifacts — migrations, audit-trail designs, the production constants) unlock with Cohort.
Refunds?
Workshop: cancel anytime, no contract. Cohort: 7-day refund window after Cohort #1 starts. We don't lock anyone in.
