A cover letter factory that takes both Visa and satoshis
Job application boilerplate, automated and monetized with a full-stack framework most people haven't tried.

What it does
Feed it a job description and your résumé; it spits out a tailored cover letter via GPT-4o. The app also tracks your job applications and subscriptions. The author sells access through Stripe (card) or Bitcoin Lightning (sats), with two tiers tied to GPT-3.5 and GPT-4.
The interesting bit
The whole thing is a showcase for Wasp, a full-stack framework that glues React, Express, and Prisma together from a config file. Google Auth, cron jobs, and database plumbing are declared rather than wired by hand. The author claims it took “a couple of days,” which either says something nice about Wasp or something unkind about the rest of us.
Key highlights
- Wasp handles auth, jobs, and DB setup via
main.waspconfig; see the file for the cheat-sheet version - Dual payment rails: Stripe subscriptions and Lightning invoices via Bolt11, with status tracked in Postgres
- Chakra UI for the React frontend; author argues it beats Tailwind for speed, though “some people are turned off”
- Cron job pings users 2 weeks before subscription expiry via SendGrid
- OpenAI prompts and API logic live in
src/server/actions.ts
Caveats
- README is a setup guide and tech-stack brag; no mention of prompt quality, output accuracy, or whether hiring managers can spot the GPT sheen
- Lightning payments route to the author’s personal Alby address, so fork-and-deploy means re-wiring that yourself
- “10x less boilerplate” is the author’s claim, not a benchmark
Verdict
Wasp-curious developers should clone this to see how the framework handles real-world concerns like auth and payments. Anyone seeking a polished, drop-in cover letter service should look elsewhere — this is a reference implementation with a paywall attached.
