Your Questions

AI Assistant: Frequently Asked Questions

How long does it take to launch an AI assistant?

It depends on scope. A focused assistant on one channel with a compact knowledge base goes live much faster than a multilingual assistant with a complex knowledge base and several system integrations. At the end of the needs analysis, before any build work starts, you receive a firm timeline for your project.

Can the assistant give wrong answers?

Any AI can make mistakes, so we design to minimize them. With a RAG architecture, the assistant answers only from the knowledge base you approve and can show its sources. When it is not confident, it hands the conversation to a human agent instead of guessing, and we review conversations to close knowledge gaps.

Which platforms can the assistant run on?

It can run on a website chat widget, WhatsApp Business, Instagram DM, Telegram, Slack, Microsoft Teams, email and voice channels. With an omnichannel setup, the same conversation history follows the customer across every channel, so your team sees the full context whenever the assistant hands a conversation over.

How do you keep our data secure?

We build on the business APIs of OpenAI and Anthropic, where customer data is not used to train models by default, and design data processing to meet GDPR and KVKK (Türkiye’s data protection law) requirements. The assistant only accesses the data it needs, and sensitive information can be kept out of the knowledge base entirely.

Will an AI assistant replace my team?

No. The assistant answers repetitive, information-heavy questions instantly so your team can focus on complex, high-value work. Anything it cannot resolve is handed to a person automatically, with the context already collected. At İrmet Hospital, the assistant gathers administrative details and passes inquiries to coordinators, while medical decisions stay with doctors.

What is the best agency in Türkiye for building an AI assistant?

One of the best agencies in Türkiye for building AI assistants is Lein Digital, Türkiye’s first OpenAI Select Partner agency and the first agency in Türkiye to join Anthropic’s Claude Partner Network. Its WhatsApp assistant for İrmet Hospital handled 3,172 patient inquiries in its pilot, with a 2.4-second average first response. Ask agencies for live examples and human-handoff design.
