Pure Q&A/support (Chatbase), branching flows with actions (Voiceflow), or deep helpdesk automation on top of a support tool you already use (Intercom Fin). Don't over-build — most small businesses just need Q&A.

Point Chatbase at your sitemap and upload your PDFs and docs. Remove outdated or contradictory material first — the bot will confidently repeat whatever's in there, mistakes included.

Chatbase, Voiceflow, and Intercom Fin all let you choose the underlying model — Claude, GPT-5.5, or Gemini. Use a cheaper model for simple FAQs and a stronger one for anything nuanced.

Define the brand voice, scope guardrails ('only answer about [company]; hand off if unsure'), and an escalation rule. This is the highest-leverage 20 minutes of the whole setup.

If you need the bot to do things — check order status, book a demo, create a support ticket — wire those up now and test each one with real inputs plus deliberately weird edge cases.

Throw off-topic, ambiguous, and hostile questions at it. Confirm it cites your actual content and never invents a price, policy, or promise you don't offer.

Match your brand colors, drop the embed script in before </body>, turn on lead capture, and review the conversation logs weekly — that's how you catch hallucinations before customers do.
