AI chatbot development

Assistants that knowyour business, not the internet

A chatbot is only useful when it is grounded in your own material. We build assistants over your documents, your product data, and your policies, with the retrieval trace visible so nobody has to take an answer on faith.

Full system architecture — Next.js frontend, NestJS backend with an LLM gateway, and a Postgres + Qdrant + Redis data layer routing across five LLM providers

What we build

The work itself,component by component

Everything listed here is something we have built into a production system, not a capability we are willing to attempt.

Document-grounded chat

Upload, index, and query your handbooks, contracts, and specs with citations on every answer.

Product and catalogue assistants

Natural-language search over structured data, so a question returns the right SKU rather than a paragraph.

Escalation to a human

Confidence thresholds and clean hand-off with the full conversation attached.

Channel delivery

Web widget, in-app panel, or WhatsApp: the same engine behind each surface.

Guardrails

Scope limits, refusal behaviour, and PII handling defined before launch, not patched after an incident.

Conversation analytics

What people actually ask, what went unanswered, and which documents are missing.

Why it matters

What changesonce it is running

Three things a buyer of this work should be able to hold us to.

RAG pipeline — ingestion (extraction, chunking, TF-IDF and dense embedding into Qdrant) and retrieval (hybrid cosine + BM25 search, RRF, reranking) feeding the LLM orchestrator

Fewer repeat questions: The assistant absorbs the questions your team answers a hundred times a month.

Grounded, not guessed: If the corpus does not contain an answer, it says so instead of inventing one.

A record of the gaps: Unanswered questions become a documentation backlog you can act on.

Stack we use for this

  • Next.js
  • FastAPI
  • OpenAI / Bedrock
  • pgvector
  • Redis
  • WebSockets

How it runs

Four stages,and you can leave after any of them

Scope

We agree what the system does and what shipping means, in writing.

Build

Short cycles in your repository, running before it is finished.

Ship

Deployed into your cloud account, reachable by a real user.

Stay

Maintenance and roadmap by the same engineers who built it.

FAQ

Questionswe get asked

How do you stop it making things up?

Retrieval-first: the model only answers from retrieved chunks, and returns a refusal when nothing relevant is found.

Can it read PDFs and scans?

Yes. OCR sits in the ingestion pipeline for scanned documents.

Who can see which documents?

Access is scoped per tenant and per role at query time, mirroring your existing permissions.
