I will fix your ai chatbot so it stops making things up


About this gig
Your AI chatbot works in the demo, then tells a customer about a refund policy you don't have. That's the moment it stops being a feature and becomes a liability.
I fix this specific problem:
1. Audit: I test your bot systematically and show you exactly where and why it invents answers, with transcripts, not vibes.
2. Fix: grounding on your real docs plus a confidence gate. When the bot isn't sure, it says "I don't know" or hands off to a human, instead of guessing.
3. Prove it: accuracy and hallucination rate measured before and after, so you see the difference in numbers, not promises.
Premium adds an automated eval suite and a CI gate, so a future prompt tweak can't quietly bring the hallucinations back.
Works with bots built on OpenAI, Claude, Gemini, open models, LangChain or custom RAG stacks.
I've published working code on exactly this (confidence gating, grounding checks, eval harnesses). It's the niche I work in daily. Very few sellers offer it, because building a chatbot is easy and making it trustworthy is not.
Not sure your bot has the problem? Message me 2 or 3 bad answers it gave, that's enough for me to tell you.

FAQ
My bot was built by someone else. Can you still fix it?
Yes, that's the usual case. The audit can start with chat access only. For the fix I'll need access to the code or the platform it runs on.
Will I need to rebuild the bot?
Almost never. The grounding and the gate are added to your existing stack. If a rebuild really is cheaper, I'll tell you before you spend more.
