First — what is a prompt?
Think of an AI agent like a new member of staff on their first day. They are intelligent and capable — but without instructions they have no idea what your business does, how you speak to customers, or what they are and are not allowed to say.
A system prompt is the set of instructions you give that new staff member before they start. It tells the AI who it is, what its job is, how to communicate, and what rules to follow. Once you give it those instructions it will follow them every single time — perfectly and consistently.
Without a system prompt your AI gives random, inconsistent, off-brand responses. With one it becomes a specialist that represents your business exactly the way you want.
WITHOUT A PROMPT
Customer asks: "What are your opening hours?"
AI replies: "I don't have access to that information. You could try checking their website or calling them directly."
❌ Useless. Off-brand. No help at all.
WITH YOUR PROMPT
Customer asks: "What are your opening hours?"
AI replies: "We're open Monday to Saturday 9am–6pm and Sunday 10am–4pm. Is there anything else I can help you with?"
✓ Accurate. On-brand. Genuinely helpful.
⏱️
Save hours every week
Turn repetitive tasks — emails, reports, support, screening — into automated workflows your agent handles without you.
🎯
Consistent results every time
Writing a good prompt from scratch is hard. The builder handles tone, rules, format and edge cases for you in seconds.
💷
No developer needed
Custom AI agents used to cost thousands. A system prompt does the same job in minutes — describe what you need, generate it, paste it in.
🔒
Your agent, your rules
You decide what the AI can and cannot say, which topics it covers, how it speaks and when it escalates to a human. No surprises.
🚀
Works with any AI
Your prompt works on Hermes, Claude, ChatGPT, Gemini and any other AI — just copy and paste. No lock-in, no extra cost.
💡
Real example
A recruitment agency used a Hermes prompt to screen 200 job applications in 4 minutes — a task that previously took a full day of manual reading.
