7 free AI prompts that replace
$500/month of software
Half of what paid tools charge for is a well-engineered prompt in a wrapper. We build those prompts and give them away. Here are seven that do the job of entire subscriptions — inside the free tier of ChatGPT or Claude.
The Ruthless Editor Pass
Paste any draft and get it back 20–30% tighter — filler cut, passive voice flipped, long sentences broken — with your worst writing habits diagnosed so you improve. It's a professional line-edit, on demand, for the price of nothing.
📋 Copy this prompt free →The SEO Content Brief Generator
Give it a keyword and it returns what tools like Surfer and Frase charge real money for: search intent analysis, title options, a complete H2/H3 outline, the 15 terms Google expects, People-Also-Ask questions and a meta description. The paid tools add live ranking data — the thinking, this prompt does.
📋 Copy this prompt free →The Cold Email That Gets Replies
Built on the only rule that matters in outreach — the first line must prove the email could only have been written to them. Under 90 words, one one-word-answerable ask, plus two follow-ups included. Outreach platforms automate sending; this replaces the part that decides whether anyone replies.
📋 Copy this prompt free →The Brand Voice Guide Builder
The headline feature of premium marketing suites like Jasper is keeping every writer on-brand. This prompt interviews you, extracts your voice into 8 precise rules with do/don't examples — and ends with a paste-able instruction block that makes ANY free AI write in your voice from then on.
📋 Copy this prompt free →The Senior Code Review
Paste code, get a principal-engineer review ranked by severity: real bugs with failing cases, security holes with the attack scenario, performance issues that matter at scale — and the single most important fix implemented in full. Not a linter; a reviewer with judgment.
📋 Copy this prompt free →The Meeting Notes → Action Machine
Paste messy meeting notes or a transcript and get the executive version: TL;DR, decisions made, an action-item table with owners and deadlines (missing ones flagged), open questions, and a ready-to-send follow-up email under 120 words. Tools like Fathom record the call for you — this prompt does the thinking part free.
📋 Copy this prompt free →The Landing Page In One Pass
It interviews you with 5 sharp questions, then writes the entire page: hero headline, pain bullets that make your exact customer flinch, how-it-works, proof section, pricing objection-handlers, the FAQ including the uncomfortable question, and a CTA with honest urgency. Copywriter output, questionnaire effort.
📋 Copy this prompt free →| Prompt | Replaces | You still need the paid tool when… |
|---|---|---|
| Ruthless Editor | ~$10–30/mo | You want in-browser corrections as you type everywhere |
| SEO Brief | ~$90–120/mo | You publish 10+ articles/mo and need live SERP data |
| Cold Email | ~$50–100/mo | You send 1,000s of emails and need sequencing/tracking |
| Brand Voice | ~$60–70/mo | A whole team needs enforced consistency in one platform |
| Code Review | ~$15–40/mo | You want automatic review on every pull request |
| Meeting Notes | ~$10–20/mo | You want auto-recording and CRM sync |
| Landing Page | ~$40–80/mo | Rarely — this one holds up remarkably well |
Total replaced: roughly $275–$460/month — if you were paying for all of them, which most solo creators and small teams half-do through overlapping subscriptions. The pattern to steal: before buying any AI-powered tool, ask "is this a model plus a prompt in a nice interface?" Often yes — and the prompt part is free.
Do these prompts really work as well as paid tools?
For the core job — the thinking and writing — usually 80% as well or better. Paid tools win on volume automation, integrations, live data and team features. Solo users and small teams can genuinely skip several subscriptions; scaled teams often can't.
Which AI should I paste them into?
All seven work in the free tiers of ChatGPT, Claude and Gemini. For writing-heavy prompts (editor, landing page, brand voice), Claude tends to edge it; for the rest, use whichever you already have open.
Can I save and reuse them?
Yes — each links to its own page in our free prompt library with a one-click copy button. Bookmark the ones you use; there are 25+ more in the library, all free.
