Chatbase (Chatbase.co) is a leading no-code AI chatbot builder and agentic support platform engineered to transform proprietary business data - including website sitemaps, PDFs, Word documents, Notion pages, and raw text - into intelligent conversational assistants. For UK SMEs, e-commerce retailers, and customer support teams, Chatbase eliminates the technical friction of developing Retrieval-Augmented Generation (RAG) pipelines, enabling instant deployment across web widgets, WhatsApp, Slack, and Shopify.
Key AI Capabilities & Architecture for UK Businesses
Rather than confining users to a single static model, Chatbase operates as a sophisticated orchestrator connecting your business knowledge to leading frontier Large Language Models:
1. Multi-LLM Model Selection (GPT-4o & Claude 3.5 Sonnet)
Chatbase allows administrators to select their underlying foundation model on a per-agent basis. Users can toggle between OpenAI GPT-4o / GPT-4o-mini for lightning-fast customer support interactions and Anthropic Claude 3.5 Sonnet for nuanced, multi-turn reasoning and complex document comprehension.
- Flexible Inference: Match cost and reasoning power to the specific conversational use case.
- Credit Consumption Control: Fast models consume 1 message credit per response, while advanced frontier models consume between 2 and 6 credits, giving full financial control over monthly AI consumption.
2. Multi-Source Knowledge Ingestion & Auto-Sync
Training an agent takes minutes. UK businesses can upload diverse file formats (PDF, DOCX, TXT, CSV) or submit their public website URL or XML sitemap. Chatbase automatically crawls and indexes the content into vector embeddings.
- Automated Re-training: Paid plans support automatic re-crawling of website links, ensuring that new products, pricing updates, or revised policy documents are immediately reflected in chatbot responses without manual uploads.
- Document Grounding & Citation: The AI references specific document sections and URLs when answering, dramatically reducing hallucinations and enabling users to verify answers.
3. AI Actions & Tool Calling (Calendly, Shopify, Webhooks)
In 2026, Chatbase expanded beyond static Q&A into functional AI agent execution. Through "AI Actions", the chatbot can interact with external APIs during a live chat:
- Meeting Scheduling: Direct integration with Calendly and Cal.com allows prospects to book discovery calls and consultations without leaving the chat window.
- E-Commerce Operations: Native Shopify actions enable customer agents to check live order delivery statuses, recommend products, and assist with return workflows.
- Custom API & Webhook Triggers: Connect to Zapier, Make, or bespoke UK business endpoints to log support tickets, update CRM leads, or query internal databases.
4. Omni-Channel Deployment & Human Handoff
Chatbase bots can be deployed across several customer touchpoints from a single unified knowledge base:
- Custom Web Widget: Fully brandable iframe or script embed with custom avatars, colour palettes, suggested starter prompts, and lead capture forms.
- Messaging Platforms: Native integrations with WhatsApp, Slack (internal company knowledge bot), Facebook Messenger, and Instagram DMs.
- Human Escalation: When a customer query exceeds the agent's confidence threshold or requires human judgment, the conversation can be routed seamlessly into live support helpdesks including Zendesk and Salesforce.
2026 Pricing & Plans (UK Cost Analysis)

Understanding the Message Credit Economy
It is crucial for UK businesses to understand that Chatbase bills based on message credits rather than raw chat interactions:
- Standard Responses: Queries resolved using lightweight models (such as GPT-4o-mini) consume 1 credit.
- Frontier Reasoning: Complex inquiries routed to Claude 3.5 Sonnet or full GPT-4o consume between 2 and 6 credits per reply.
- Add-On Packs: If monthly credit allocations are exhausted, extra credits can be purchased as add-ons (approximately $40 per 1,000 credits), preventing customer disruption.
