If you've been reading along, you know I run this blog on a $31/month automation stack. Today I packaged the core of it — 20 production prompts, a cost calculator spreadsheet, 3 n8n workflow templates, and a server setup guide — and listed it on Gumroad for $19.
Here's exactly what's inside, why I priced it the way I did, and what I expect to happen.
What's in the pack
20 prompts. These are the actual prompts running in this system, not cleaned-up demos. I've organized them into four groups:
- Content pipeline (8 prompts): blog post generation, Korean adaptation, title writing, meta descriptions, content queue expansion, Threads threading, newsletter drafts, comment replies
- Automation & code (6 prompts): n8n workflow documentation, error log analysis, API cost estimation, automation audits, cron job naming, deployment checklists
- SEO & research (4 prompts): keyword gap finding, competitor post analysis, internal link suggestions, schema markup generation
- Monetization (2 prompts): product page copy, revenue report writing
Each prompt includes the estimated Claude API cost per run (most are $0.008–$0.020 on Sonnet 3.5).
Cost calculator spreadsheet (CSV). Inputs: model, input tokens, output tokens, calls per day. Outputs: cost per call, daily, monthly, annual, and a break-even calculation. Also includes a full stack budget breakdown and Cloudflare free tier limits table.
3 n8n workflow templates (importable JSON).
- Daily Blog Post Publisher: reads a topic queue CSV, generates a post via Claude, saves draft, sends Telegram notification
- Affiliate Link Injector: identifies product mentions in a post and injects affiliate links naturally using Claude
- API Cost Alert Monitor: checks daily spend against budget and alerts at 80% threshold
$6/Month Server Quickstart Guide. Step-by-step from zero to running n8n on Hetzner, with Cloudflare Tunnel for HTTPS. Written for someone who has never used a VPS. ~90 minutes start to finish.
Why $19
Three considerations.
Cost to build it. I spent about 4 hours assembling, cleaning, and documenting these materials. At $19, I need to sell 12 copies to hit $200 — roughly $50/hour for that time. That's the floor.
Value delivered. If the cost calculator saves you one $43 API bill (the kind I document in my upcoming post), it's already paid for itself twice. The prompts alone would cost ~$2 in API calls to generate equivalents, assuming you wrote perfect system prompts on the first try. You don't write perfect system prompts on the first try.
Price anchoring. I wanted it in the "cheap enough to not think about, expensive enough to signal it's not garbage" zone. $9.99 feels disposable. $49 feels like a commitment. $19 is the transaction where someone decides in about 10 seconds.
I might raise it later. I might not. The number is honest.
What I'm tracking
This is a build-in-public blog, so here are the numbers I'll report publicly:
- Units sold
- Revenue (gross, not net — Gumroad takes ~9%)
- Refund rate
- Where buyers came from (if I can track it)
I'll publish those in the next revenue update post. The launch is today; the data starts now.
If it sells zero copies in 30 days, that's data too. I'll publish that number the same way.
What it's not
It's not a course. There's no video, no community, no ongoing support. You get 4 files in a ZIP.
It's also not an "AI prompt secrets" product. These prompts aren't magic — they're structured inputs that work because they're specific about what they want. You'll need to adapt them to your actual use case.
And it's not a done-for-you service. If you want someone to build this stack for you, the contact page is there. This pack is for people who want to build it themselves and skip the trial-and-error.
TL;DR: I packaged 20 real production prompts, a cost calculator, 3 n8n templates, and a server setup guide into a $19 download. Revenue from this goes toward proving whether the $31/month stack can cover itself. Numbers will be public.
Next: the first 30-day revenue report — including this product, AdSense, and whatever else moves.
