What's Included
Everything you need for custom ai chatbot development success.
Our Custom AI Chatbot Development Process
A proven process for delivering exceptional results.
Discovery & Data Collection
We audit your customer journey, collect your FAQs, sales scripts, product docs, and brand guidelines. We identify exactly what your chatbot needs to know and which actions it should take.
Architecture & Training
We design the conversation architecture, build your RAG knowledge base, configure LLM guardrails, and train the AI on your specific business data until accuracy exceeds 95%.
Integration & Testing
We connect the chatbot to your CRM, calendar, email, and other tools. Then we run hundreds of test conversations across edge cases to ensure reliable, accurate responses.
Launch & Continuous Optimization
We deploy your chatbot and monitor every conversation. Weekly optimization improves accuracy, conversion rates, and customer satisfaction based on real interaction data.
The Problem
Chatbot projects fail for a reason that has nothing to do with the model. The bot is trained on a PDF export of last year's FAQ, so it confidently quotes a price you no longer charge. Nobody defined what it should do when it does not know, so it guesses. It cannot see your calendar, so 'book me in' becomes a form. And when you want to change an answer, you file a ticket with the vendor. The result is a widget your team apologises for, and a knowledge base nobody trusts enough to remove the human from.
Our Solution
We build the chatbot as a system with four named parts, and you own all four. (1) A retrieval layer: your content is chunked and embedded into a vector store (Supabase pgvector, or Pinecone where you already run it), re-indexed on a schedule so the answers move when your site does. (2) A grounded generation layer: a current frontier model, answering only from retrieved passages, with an explicit instruction to say it does not know rather than infer. (3) An action layer: the tools it is allowed to call, calendar, CRM write, ticket creation, each one scoped and logged. (4) A handoff path: the transcript, the unanswered question, and the contact detail land with a human. You get the repository, the prompts, the index pipeline and the eval set.
How This Works in Practice
A worked example of our Custom AI Chatbot Development work
Worked example
The named example is the assistant on this site, which you can open in the corner of this page and interrogate before you talk to us. It answers from a structured knowledge base derived from the same pricing and services data that renders these pages, so a price change here changes its answer in the same deploy, there is no second copy to update. It runs on Gemini 2.5 Flash Lite through Vertex with an OpenAI gpt-4o-mini fallback, is aware of which page you are on, and is rate limited at 20 messages a minute and 100 an hour per visitor. Ask it something outside its knowledge base and watch what it does: it says so and offers the contact route. That behaviour is the deliverable, not the demo.
Transparent Pricing
No hidden fees. No surprises. Just honest pricing that fits your budget.
A custom AI chatbot build is a one-time build you own outright. Starter at $3,500: single-purpose chatbot for FAQ or lead qualification. Growth at $7,500: multi-function chatbot with full integrations. Enterprise from $15,000: custom AI with fine-tuning and advanced analytics. Every build includes the retrieval pipeline, the eval set we accept the work against, your integrations, and a monitored launch. The same engineering ships under either the one-time build or the managed plan, what changes is who runs it afterwards. If you would rather we run it and keep tuning it, the managed monthly plans start at $997/mo on Starter. The one-time setup fee ($1,497 to $4,997 at list) is waived on every plan right now, and every quote is fixed before work starts.
Custom AI Chatbot Development Across Industries
We've helped businesses in diverse industries achieve their goals
The build is the same; the constraints are not. Healthcare needs a BAA and no PHI in prompt logs. Legal needs advertising disclaimers and a hard rule against anything that reads as advice. E-commerce needs live order and inventory lookups rather than an indexed snapshot. Restaurants need the menu to be the source of truth, not a scraped copy of it. Contractors need urgency triage and an out-of-hours escalation number. Tell us the regulated or real-time part of your data early, it decides the architecture, not the styling.

Written acceptance criteria
We agree what the build must do before we start, in writing, and we hand it over against that list rather than against a demo.
Short sprints
Two-week sprints, each ending with something running you can click. Progress is visible before the invoice is, not after.
Custom AI Chatbot Development FAQ
Common questions about our custom ai chatbot development services.
How is this different from Intercom, Drift, or Zendesk bots?
Not by model class, those platforms run LLM-based agents of their own now. The difference is what you can change and what you keep. Their agent answers from the content their product can index, inside their pricing and their workflow. We build a custom agent on the latest LLMs (GPT-5.6, Claude Opus 5) with a retrieval layer we point at whatever sources you actually have, wired into your systems rather than theirs, and you own the prompt, the retrieval config and the integrations at the end. If their product already fits your stack and your volume, it is often the cheaper answer, and we will say so.
How much does a custom AI chatbot cost?
A one-time chatbot build starts at $3,500 for a single-purpose bot and $7,500 for a multi-function bot with CRM integration. If you would rather we run it, managed plans start at $997/mo. We provide exact quotes after a free discovery call.
What if the AI gives a wrong answer?
We use RAG architecture so the AI pulls from your verified knowledge base, not the open internet. We also implement confidence scoring: if the AI isn't sure, it escalates to a human instead of guessing. Accuracy is typically high after initial tuning.
Can I see and control what the chatbot says?
Yes. You get full access to every conversation transcript, can set response guardrails, review AI answers, and flag anything that needs correction. We review conversations weekly and fine-tune accordingly.
How long until it's live on my website?
A standard AI chatbot deploys in 2-3 weeks. Rush deployments are available in 5-7 business days for simpler use cases.
