"Dear Mr. Johnson, I am writing to express my interest... I led a team of 6, improved CSAT by 35% and am proficient in Salesforce."
- Invents a team of 6, a 35% CSAT gain and Salesforce skills
- Guesses a hiring manager name
- Opens with the line every letter uses

Questions
Is this better than asking a plain chatbot?
A plain chatbot starts from zero every time. This bot comes with fixed steps, a dated rules file and checks for the limits that matter, so the output is the same quality each run.
Do I need a paid AI plan?
Most setups work on paid ChatGPT, Claude or Grok plans. Free plans may cut long outputs short. Each bot page lists the plan it was tested on once testing is done.
Why pay when free prompts exist?
Free prompts are a fine start. You pay for the tested setup, the knowledge file and the refund if it fails on your real task.
What if it does not work for me?
Email us the output within 14 days and we refund. No forms.
