FAQ

Will an AI customer service assistant replace my human staff?

In 2026, the trend is 'augmentation' rather than 'replacement'. AI handles the repetitive 60-80% of queries (tracking, passwords, basic FAQs), allowing your human agents to focus on high-value, complex emotional issues that require empathy and critical thinking.

How difficult is it to switch from a legacy system to an AI assistant?

Switching costs vary. If your data is already in a structured knowledge base, moving to a tool like Intercom is fast. If your data is siloed in old PDFs or emails, you may need AI integration services to clean and migrate your data first.

Are there free options for very small UK businesses?

Yes, tools like Tidio and Freshworks offer generous free tiers. However, be aware that 'free' often means limited AI tokens or a branded chatbot. For professional-grade automation, a paid tier is usually necessary to remove branding and increase resolution accuracy.

How does GDPR affect the use of AI assistants in the UK?

GDPR requires transparency. You must inform users they are interacting with an AI and ensure the provider has a Data Processing Agreement (DPA) that specifies where data is hosted. Most top-tier providers now offer UK or EU-based data residency to satisfy these requirements.

Can AI assistants handle phone calls, or just text?

Modern ai customer service assistants are increasingly multimodal. While most start with chat, enterprise tools like Zendesk and Ada integrate with AI voice agents that can handle inbound calls with near-human latency, though these typically require a higher pricing tier.
