OpenAI & Claude integration
wired straight into your product
Custom GPTs, prompt engineering, and chatbot interfaces that plug directly into your existing app, website, or CRM, not a bolt-on widget, a properly integrated feature.
LLM integration that fits your
product, not a generic chatbot.
Whether it's OpenAI, Claude, or an open-source model, the integration is built around your actual product flow, data, and brand voice, not a copy-pasted widget.
OpenAI & Claude API Integration
Direct integration with OpenAI and Anthropic Claude APIs, streaming responses, function calling, structured outputs, and proper error handling built into your product's backend.
Custom GPT Development
Purpose-built custom GPTs for internal tools, customer support, or content workflows, configured with your knowledge, tone, and guardrails.
Prompt Engineering & Optimisation
Systematic prompt design and testing, not trial and error, to get consistent, on-brand outputs from the model you're using.
Chatbot Interface Development
Chat UI built into your existing website or app, not an embedded third-party iframe, matching your design system and user flow.
Zoho AI Integration
AI-assisted data entry, intelligent lead routing, and Zoho Analytics dashboards, bringing LLM capability directly into your CRM workflow.
Document & Content Generation
LLM-powered drafting for reports, emails, and content, with templates and review steps so output stays on-brand and accurate.
06Multi-Model Strategy
Routing logic between models, using cheaper models for simple tasks and stronger models only where the task actually needs it.
07LLM Feature Audits
Already shipped an AI feature that's inconsistent or expensive? We audit the prompts, model choice, and architecture and fix what's broken.
A chatbot widget isn't the same as a properly integrated AI feature
Bolting on a generic chat widget is fast, but it rarely matches your brand, data, or actual user flow. We integrate the model into your product the way any other core feature would be built.
Native Product Integration
Built into your existing frontend and backend, not an embedded third-party script that breaks your design.
On-Brand Prompt Design
Prompts engineered and tested for your tone, domain, and edge cases, not a default system prompt.
Cost-Aware Architecture
Token usage, caching, and model selection designed so AI features don't quietly drain your budget.
Full Code Ownership
Integration code, prompts, and configuration belong to you, switch providers any time without rebuilding.
From prompt draft to a live integration in 4 stages
Every LLM integration follows the same process, because consistent output comes from disciplined prompt design, not luck.
Design, Prompt, Integrate, Tune
Define the feature and pick the right model
We map the exact use case and choose between OpenAI, Claude, or other models based on cost, quality, and latency needs.
Design and test prompts systematically
Prompt drafts tested against real inputs and edge cases until outputs are consistent and on-brand.
Build the feature into your product
API integration, streaming, structured outputs, and UI built natively into your existing app or CRM.
Tune cost and quality, then ship
Token usage and response quality tuned before launch, with monitoring in place to catch drift after.
Custom-Built ChatGPT & LLM Integration, Frequently Asked Questions
Answers to the questions US & UK clients ask us most.
What does a “custom-built ChatGPT” mean for my business?
A custom-built ChatGPT is a chat assistant trained on your tone, rules, and data and wired into your product, website, or CRM. Unlike the public ChatGPT, it answers only from your approved information, follows your brand voice, and can trigger actions in your systems.
Can you integrate ChatGPT or Claude into our existing app or CRM?
Yes. We provide ChatGPT integration and Claude integration services that connect to your existing app, website, Slack, or CRM through secure APIs, no rebuild required. We handle prompt engineering, context handling, and the chat interface.
Will our custom ChatGPT answer only from our own data?
Yes, by pairing the LLM with a retrieval (RAG) layer, your custom ChatGPT draws answers from your documents and database, with citations, instead of generic internet knowledge. This keeps responses accurate and prevents off-topic or made-up answers.
How much does a custom ChatGPT integration cost?
Pricing is fixed-scope based on the integrations, data sources, and interface you need. A focused ChatGPT integration is an affordable, fast project; larger multi-system builds are quoted up front. Contact us for a free, no-obligation estimate.
Which is better for my use case, OpenAI GPT or Anthropic Claude?
It depends on the task. OpenAI GPT models are strong all-rounders with broad tooling; Anthropic Claude often excels at long documents, careful reasoning, and safety-sensitive work. We help you choose, and many of our builds use both, routing each request to the best model.
