Chatbot System Prompt Generator
Piper, the built-in AI bot, interviews you - or reads your website - and writes a production-quality system prompt for your customer support chatbot: persona, scope, grounding, refusals, escalation, formatting and safety, each section refinable on its own.
The difference between a support bot that helps and one that embarrasses you is mostly the system prompt - and most teams write theirs in five minutes and never touch it again. This free generator does the job properly: it asks the right questions, writes a structured 7-section prompt, and lets you refine each section until it matches how your team actually works. No account needed.
Interview
Piper asks about your product, policies and escalation paths - or reads your website and drafts from that - so the prompt reflects your business, not a generic template.
Refine
The prompt is built in 7 sections - persona, scope, grounding rules, refusal rules, escalation, formatting and safety - and each one can be regenerated or tweaked independently.
Launch
Export vendor-neutral plain text that works in any bot platform, plus a suggested first message and example questions - a complete launch kit.
A customer service prompt generator that interviews you
A good system prompt answers questions most teams have never been asked: what should the bot refuse to do, when does it hand off to a human, what tone fits your brand, what happens when the docs do not cover a question. Piper asks those questions in a short conversational interview - or, if you prefer, reads your website and infers sensible answers to confirm. Either way the output is grounded in your business rather than a template with your company name pasted in.
A system prompt for customer support, section by section
The generated prompt has 7 sections, because production support prompts have real jobs to do: a persona that sets tone, a scope that says what the bot covers, grounding rules that keep answers tied to your content, refusal rules for what it must not attempt, escalation criteria for reaching a human, formatting rules for readable replies, and safety guardrails. Each section is independently refinable - make the persona warmer or the refusals stricter without touching the rest - so you can iterate to something you would genuinely put in front of customers.
An AI prompt generator for customer service that works anywhere
The export is deliberately vendor neutral: plain text with clear section headings, no proprietary syntax, so the same prompt works in Intercom Fin, Zendesk AI, a custom GPT, or a Chat Thing bot. You also get a suggested first message and a set of example questions to seed your widget - a small launch kit rather than a bare prompt. Every session has a share link, and its .md variant is the paste-ready prompt itself, so handing it to a teammate or dropping it into a platform is one link.
FAQ
Your questions, answered
What is a chatbot system prompt generator?
It is a tool that writes the system prompt - the standing instructions that define a chatbot's persona, scope and rules - for you. This one is specialised for customer support: Piper, the built-in AI bot, interviews you or reads your site, then writes a structured 7-section prompt you can refine and export.
Is it free?
Yes. Interview, generate, refine and export at no cost. It is built by the team behind Chat Thing as a free tool - no account and no credit card needed.
What are the 7 sections of the generated prompt?
Persona, scope, grounding rules, refusal rules, escalation, formatting and safety. Together they cover the decisions a production support bot actually has to make - and each section can be refined or regenerated on its own.
Which bot platforms does the prompt work with?
Any of them. The export is vendor-neutral plain text with clear section headings and no proprietary syntax, so it pastes into Intercom Fin, Zendesk AI, a custom GPT, a Chat Thing bot, or anything else that accepts a system prompt.
Is this a chatbot personality generator too?
The persona section covers exactly that - name, tone, level of formality, how the bot refers to your company - and you can refine it independently until the personality fits your brand. The other six sections then make sure personality is backed by rules.
Can it write the prompt from my website instead of an interview?
Yes. Give Piper your URL and it reads your site, infers your product, audience and policies, and drafts the prompt from that - then confirms the details it guessed so you can correct anything before you export.
What else do I get besides the system prompt?
A suggested first message and a set of example questions for your chat widget - the pieces you need to actually launch a bot, not just configure one. The share link's .md variant is the paste-ready prompt itself.
Will a better prompt fix my bot's wrong answers?
Only partly. A prompt controls behaviour - tone, scope, refusals, escalation - but it cannot fix missing knowledge. If your bot's answers are wrong because your docs are thin, grade your help centre with our Knowledge Base Grader and fix the content too.
Do I need a Chat Thing account?
No. The generator runs in your browser with no signup. If you want somewhere to put the finished prompt, Chat Thing can turn it into a live support bot trained on your content - but it is never required to use the tool.
