Claude Integration Services

Claude is Anthropic's most capable AI model, strong on nuanced reasoning, long-context analysis, and instruction-following. Integrating Claude into a production product is a different problem from using the API in a demo: prompt architecture for consistent outputs, context window management for long documents, tool use configuration, cost and latency optimisation, and monitoring across real user inputs.
We build Claude integrations for production use cases, document analysis, AI assistants, knowledge retrieval, workflow automation, and conversational interfaces, with the reliability engineering that makes them viable products.

Claude in production is an engineering problem, not just a prompt problem

Getting Claude to produce a useful answer in a demo is easy. Getting it to produce consistent, accurate, appropriately-formatted answers across thousands of real user queries, with edge cases, adversarial inputs, and production load, requires prompt architecture, context management, tool integration, evaluation, and monitoring.

We build Claude integrations that work in production, not just in demos.

Capabilities

What we build with Claude

Document analysis and extraction

Claude-powered document processing, contract review, legal document analysis, financial report extraction, compliance document classification, and long-document summarisation. Claude's 200K token context window handles documents that other models require chunking for: a 150-page contract, a full annual report, or an entire regulatory submission fits in a single context window, which means the model can reason across the whole document rather than independently processing fragments.

Document processing pipelines built with structured output enforcement: every extraction output is validated against a JSON Schema before being written to your system. If Claude returns a date in an unexpected format, a number as a string, or omits a required field, the validation layer catches it before it reaches your database. For contract analysis: key clause identification, obligation extraction, date and party name extraction, and risk flag classification, all returned as structured data your downstream system can act on, not a prose summary someone has to read. Human review workflows are built for the high-stakes case: a reviewer sees the original document alongside the extracted fields, with confidence scores on each extraction, and accepts or corrects each field individually. Corrections are logged as training data to improve accuracy over time. Accuracy validation runs against a labelled test set before deployment: no integration goes live without knowing its extraction accuracy on your document types.

Knowledge base assistants

AI assistants that answer questions from your organisation's documents, data, and knowledge base, using RAG pipelines that retrieve relevant passages and pass them to Claude for synthesis. Internal knowledge assistants, product documentation Q&A, and customer-facing help systems that give accurate, sourced answers rather than hallucinated responses.

Conversational interfaces

Multi-turn conversational AI built with Claude, customer-facing chatbots, internal support assistants, interview and assessment tools, and AI form completion. Conversation state management, context window handling for long conversations, and escalation to human agents when confidence is low.

Content generation pipelines

Content generation systems powered by Claude, structured content production for marketing, product descriptions, reports, and personalised communications. Prompt systems with style guides, format constraints, and quality validation. Batch processing pipelines for high-volume content generation with review workflows.

Tool use and agent workflows

Claude agents that use tools to complete multi-step tasks, database queries, API calls, web search, file operations, and code execution. Tool definitions designed for reliable tool selection and parameter passing: tool descriptions written in plain language that makes the intended use unambiguous, parameter schemas with description fields that guide parameter value selection, and input validation on the application side before any tool executes.

Agent workflows for research, data enrichment, automated reporting, and workflow automation tasks. Error recovery built into every agent workflow: when a tool call fails (API rate limit, database connection error, malformed response), the agent receives the error and retries with backoff or switches to an alternative approach, rather than the agent loop failing silently. Guardrails are implemented as hard constraints that run before tool execution: a database agent cannot execute a DELETE or UPDATE statement, a customer-facing agent cannot access internal cost data, a research agent's web searches are logged for audit. Agent state persistence for long-running workflows: a research agent working through a multi-hour task checkpoints its progress to a database so a crash or timeout does not restart the entire workflow from the beginning. Parallel tool use for agents that need to call multiple APIs simultaneously: Claude's tool use API supports requesting multiple tool calls in a single response, and our runtime executes them in parallel to reduce total task completion time.

Claude with custom data access

RAG pipelines connecting Claude to your proprietary data, product databases, customer records, internal documentation, and knowledge management systems. Vector databases (Pinecone, Weaviate, pgvector), embedding pipelines, and retrieval strategies optimised for your data type and query distribution. Claude answers about your specific data, not generic knowledge.

Process

How we build Claude integrations

Prompt architecture for consistency

Production Claude integrations start with structured system prompt architecture, role definition, hard constraints, output format specifications, and domain grounding. Few-shot examples for complex output formats. Chain-of-thought for multi-step reasoning tasks. Prompts designed to produce consistent outputs across diverse user inputs, not optimised for the inputs you thought of.

Evaluation before deployment

We build evaluation frameworks before deploying any Claude integration, test cases covering your real distribution of user inputs, metrics for output quality, format compliance, and accuracy, and pass thresholds agreed before development starts. No Claude integration goes to production without being measured against real inputs first.

Context and cost management

Context window management for long documents and conversations, summarisation strategies, sliding window approaches, and RAG for context that exceeds the window. Prompt caching configuration for repeated large system prompts. Model routing for cost optimisation. Cost monitoring per interaction so you can track inference costs as usage scales.

Monitoring and observability

Production monitoring for Claude integrations: request volume, latency, cost per interaction, output quality metrics, and error rates. Alerting when quality metrics degrade or costs increase unexpectedly. Logging of inputs and outputs for debugging and evaluation updates. The observability layer that lets you manage the integration as a production system.

How we work

From scope to shipped

Every Claude integration follows the same four phases. Scope is locked and price is fixed before development starts.

  1. Week 1
    01

    Discovery and scope

    We map the use case, the data sources, and the user workflow. You leave week 1 with a written scope document, a system prompt architecture plan, and a fixed-price quote. No development starts without your sign-off.

  2. Weeks 2-3
    02

    Prompt architecture and design

    System prompt design, output format specifications, and few-shot examples before any production code. Prompt decisions made here cost a fraction of what they cost in week 8. The architecture is locked before the build starts.

  3. Weeks 4-12
    03

    Build, integrate, and evaluate

    API integration, RAG pipeline, tool configuration, and evaluation framework running in parallel. Working integration at a staging URL by the end of sprint one. Bi-weekly demos. No integration ships without passing agreed accuracy thresholds.

  4. Weeks 12+
    04

    Deploy and monitor

    Production deployment with cost and quality monitoring activated on launch day. 8 weeks of post-launch support included. Alerting configured before go-live.

Why us

Why teams choose RaftLabs for Claude integration

  1. Senior engineers build what they scope

    The engineers who assess your Claude integration also build it. No bait-and-switch, no offshore handoff after the contract is signed. The team you meet in week 1 ships in week 12.

  2. Fixed price before development starts

    We scope the work, calculate the cost, and lock it in writing before any development starts. A scope change is a change request: priced, agreed, or dropped. It never absorbs into the project and appears on the final invoice.

  3. 9 years and 100+ products shipped

    Clients include Vodafone, T-Mobile, Aldi, Nike, Cisco, and Lockheed Martin. Track record across AI, SaaS, mobile, automation, and enterprise platforms in healthcare, fintech, logistics, and hospitality.

  4. Compliance built in from the start

    GDPR, HIPAA, SOC 2 — compliance requirements are scoped in week 1, not retrofitted before launch. We have shipped HIPAA-compliant AI systems for US healthcare clients and GDPR-compliant products for European markets.

Claude integrations that work reliably at production scale

We engineer the reliability layer that makes Claude a trustworthy part of your product. Fixed cost.

Frequently asked questions

We integrate with the current Claude model family from Anthropic: Claude Opus (highest capability, for complex reasoning and long-context tasks), Claude Sonnet (balanced capability and cost, the most commonly used model for production applications), and Claude Haiku (fastest and most cost-effective, for high-throughput simpler tasks). We help you select the right model for your specific use case based on the required reasoning complexity, context length, latency requirements, and cost per call. We also design systems to route between models, using Haiku for simple classification and Sonnet or Opus for complex analysis, to optimise cost without sacrificing output quality.

Claude has one of the longest context windows available, 200K tokens for Claude 3 models, making it well-suited for long document analysis, whole-contract review, long conversation history, and multi-document synthesis. For use cases where documents fit within the context window, Claude can process them directly without chunking. For document sets that exceed the context window, we build RAG pipelines that retrieve the most relevant passages for each query rather than loading the full document. The choice between direct context loading and RAG depends on your use case: direct loading is simpler and preserves full document coherence; RAG scales to document sets of any size.

Claude API costs are driven by token consumption, input tokens (prompt + context) and output tokens (model response). Cost optimisation strategies we apply: (1) Prompt compression, removing unnecessary text from system prompts while preserving effectiveness. (2) Context management, summarising conversation history rather than appending the full history to every request. (3) Model routing, using Claude Haiku for simple tasks and Sonnet/Opus only where complexity warrants it. (4) Prompt caching, Anthropic's prompt caching feature reduces costs by up to 90% for applications that repeat large system prompts across many requests. (5) Output length control, constraining response length where shorter answers are sufficient. We monitor cost per interaction in production and report on efficiency.

A focused Claude integration, one use case (document Q&A, AI assistant, or content generation) with prompt architecture, RAG pipeline, and basic monitoring, typically runs $10,000--$30,000. A complete AI product with multiple Claude-powered features, custom tool integrations, user-facing interface, and production monitoring runs $30,000--$100,000+. Cost depends on the number of use cases, complexity of the RAG pipeline, custom tool integrations required, and UI/UX development included. We scope every project before pricing it.

Yes. We sign mutual NDAs before any scoping conversation. Most Claude integration projects involve proprietary data, internal knowledge bases, or competitive workflows, so we treat confidentiality as a baseline condition, not a negotiation point.

Yes. Most Claude integration work connects Claude to existing systems, an internal knowledge base, a CRM, a document management platform, or a customer-facing product. We design the integration layer around your existing APIs and data schemas. If your system lacks an API, we build a connector as part of the project scope.
