Custom AI chatbot development company

Custom AI chatbots and voice bots, grounded in your business

Chat and voice assistants that answer from your own data, take actions in your systems, and hand over to a human cleanly.

What it is

A custom AI chatbot is a conversational assistant built on a large language model and connected to your own content and systems, so it answers from your approved information rather than the open internet. A voice bot adds speech recognition and speech synthesis so the same assistant works over the phone or inside an app. Tech Insane builds both, with retrieval over your knowledge base, integrations with your CRM or booking tools, and measurable accuracy targets.

Outcomes

What changes for your business

Faster answers, around the clock

Customers and staff get accurate answers in seconds, in any time zone, without waiting for a queue.

Fewer repetitive tickets

Common questions are resolved by the assistant, so your team spends time on the conversations that need judgment.

Answers you can trust

Responses cite your sources, and the bot says "I don't know" and escalates rather than inventing an answer.

  3. Build integrations (CRM, booking, order status) as explicit, permissioned tools.

  4. Test against a scripted conversation set, including adversarial and off-topic prompts.

Two ways to engage

AI chatbots and voice bots: frequently asked questions

How is a custom AI chatbot different from ChatGPT?

A custom chatbot answers from your approved content, connects to your systems, follows your policies, and is measured against your own test conversations. General-purpose chat tools do none of that by default.

How long does it take to build an AI voice bot?

A focused voice bot for one use case, such as appointment booking or order status, typically takes 4–10 weeks including telephony integration and testing. The timeline depends on integrations and languages.

Will the chatbot make things up?

We design against it: retrieval from your sources, answer citations, explicit refusal rules, and automated tests that check for unsupported answers before each release.

Can the bot hand over to a human?

Yes. Handover to live chat, email, or a phone agent is part of every build, with the conversation context passed along so the customer does not repeat themselves.
