AI-agent first · Open source · Runs on Cloudflare’s free plan

Your website’s AI assistant.
Owned by you.

HelpPuff learns your website, answers visitors, captures leads, hands chats to your team and turns requests into jobs, all inside your own Cloudflare account. No subscription, no server to patch, no chatbot vendor holding your customers.

Your AI agent sets it up. Make a folder, open Claude Code, Codex or Cursor in it and paste one prompt. Nothing to configure by hand, unless you want to.

AI-agent first

Make a folder. Paste one prompt. Your agent does the rest.

You don’t configure HelpPuff by hand (though you can). Claude Code, Codex, Cursor or OpenCode takes an empty folder to a tested assistant on your site: it deploys it, learns your website, asks a real question and hands you the links. You only tell it your website and sign in to Cloudflare.

mkdir my-assistant && cd my-assistant
Open your agent there: claude codex cursor .
Paste the prompt

Shared instructions for every agent: no plugin, skill or MCP server
Everything the dashboard does is in the CLI and admin API
Any model or knowledge base with one command, even your own code
You step in only for sign-in or a real business decision

Then change anything by asking:

“Make the chat button orange and call the assistant Sam.”
“Don’t ask for details before the chat starts.”
“Never quote prices; offer a callback instead.”
“Turn on live chat so my team can answer.”
“When someone asks where their order is, check our order API.”
“Go through my HelpPuff settings with me.”

Why HelpPuff

The convenience of a hosted chatbot, without renting one.

Hosted chatbots charge monthly, put features behind higher plans and keep your conversations. Building your own means wiring a model, retrieval, storage, a widget and a dashboard by hand. HelpPuff is the third option.

Make it yours

Looks like your brand. Not like a plugin.

Colour, theme, fonts, corners, launcher, greeting, shortcuts, forms and wording are all settings, with readable contrast worked out for you. Every picture on this page is a real screenshot.

A home screen with four shortcuts in a serif font and teal accent — **A home screen that sells**Questions, calls and useful pages, suggested from your website and yours to edit.

A pre-chat form asking for name, email and occasion, with a privacy note — **Leads before the first message**Your fields, your wording, a privacy note.

The widget full screen on a phone, with a carousel of services — **Made for phones**Full screen, thumb-friendly, keyboard-aware.

Booking in the chat

The AI finds the time. HelpPuff books it.

Visitors pick a free time in a calendar right in the chat, and HelpPuff books it, on a job, in your calendar too. The assistant suggests times but never books: we tested AI models booking by themselves, and even the best sometimes booked the wrong time, or booked twice.

A calendar in the chat: days along the top, free times below — **Free times, in their time zone**From your hours, or from Cal.com, Calendly, Google Calendar or Outlook.

A booked appointment in the chat, with Change time and Cancel booking — **Booked once, changeable**No double bookings, whichever model you use.

Three choices. No appointments, your booking link, or the date picker. A booking link on your site is found for you.
Synced both ways. Bookings are written to your calendar, and events made there show in HelpPuff.
On a job, on the calendar. Each appointment joins the contact's job, with reminders and webhooks.

The dashboard

A CRM that fills itself.

Every deployment includes a dashboard for your team: conversations arrive summarised, contact details become leads, and callback requests become tasks. Its data lives in your own D1 database.

Every chat summarised and labelled: intent, sentiment, lead quality, next step, and the questions it could not answer.
