Show HN: Dumped Wix for an AI Edge agent so I never have to hire junior staff

Background

I run a building‑design consultancy and got tired of paying Wix $40 / month for a brochure that couldn’t answer simple service questions, while I wasted hours handling the same FAQs. I shut it down and spent four months building a “talker”.

The stack is a bit of a hack: Netlify’s 10‑second serverless timeout forced me to split the agent into three pieces—Brain (Edge), Hands (Browser), and Voice (Edge). I haven’t coded in 30 years; this was three steps forward, two steps back, heavily guided by AI.

Proof of Concept

Two weeks ago a licensed architect tried to attack the bot to prove my business model harms the profession. The AI (DeepSeek‑R3) completely dismantled his arguments, responding with a hilariously caustic rebuttal.

Log of the exchange:

Challenges (Battle Scars)

  • Web Speech API works fine until someone speaks Chinese without toggling the language mode; it then spits out English phonetic gibberish.
  • Liability is the killer. If the model hallucinates a building‑code clause, we’re dead—insurance won’t cover us.
  • Intent handling was the hardest part: making a single LLM pivot seamlessly from a warm, principal‑like tone with a homeowner to a defensive “bulldog” when attacked by a peer. This took about 2.5 months of tuning.

Audit

We publish audit logs to keep ourselves honest and ensure the system stays hardened.

Token Management

We burn through tokens with an “Eager RAG” hack (pre‑fetching guesses) to improve responsiveness.

Persistence Strategy

I ripped out the “essential” persistent databases—less than 5 % of visitors ever return, so we don’t bother storing sessions. If a client drops mid‑query, their session simply vanishes; there are no server‑side queues.

Goal

The point is to let me operate with a network of seasoned professionals while trimming the fat.

Try to break it. I’ll be in the comments.
