Fine-tune your AI agent’s behavior using custom instructions. Think of it as having full control over the “brain” behind your replies. You can tailor the assistant to match your use case, add tone preferences, rules (e.g., share a Calendly link when a contact requests a meeting), or even prompt examples—whatever makes your day easier.

Say hello to Gen AI search in your Gmail inbox! Our AI agents can now look up information beyond your knowledge base. So, next time you have a quick query not covered by your past emails and linked knowledge base, your Gmelius AI assistant can draft an answer from data found on Google Search (e.g., your pricing details, address) without interrupting your flow of work.
You were wondering how you can teach the AI to sound like you? Good news: it already does. Once you enable your AI Reply Assistant, they can analyze your sent emails from the last 2 years to learn your tone, writing style, and expertise, automatically.
You can still enrich your Agent with a custom knowledge base. Combine that with custom instructions, and you’ve got a fully personalized reply assistant that works just like (a faster version of) you.
P.S. Tell your teammates! Our AI assistant is even smarter in shared inboxes now.
