Show HN: Lumail – Autonomous AI Agent for Gmail Inbox

Hi HN,

I’m Rem, a solo founder, and I just launched Lumail (https://lumail.ai) – an autonomous AI agent that lives in your Gmail inbox. It reads full email threads, pulls in context from your past conversations, checks your Google Drive files or uploaded docs, and takes action: labels emails, drafts replies, or skips when it makes sense.

Why I built it? I was tired of manually handling repetitive support and operations emails – tracking orders, answering the same questions, digging through past threads. I didn’t want an assistant I had to prompt. I wanted an agent that understood context and acted on its own.

What it does:

- Monitors your Gmail inbox using official OAuth - Reads entire threads to understand context before acting - Uses your Google Drive docs or uploaded files as its knowledge base - Drafts smart, customizable replies using with your prompt logic - Applies/removes labels to organize inbox as needed - Works autonomously in the background, with full auditability - Learns your writing style and tone

It’s a decision-making agent built for operators, founders, and support-heavy teams. You can fully customize prompts and see exactly what the agent does before sending anything.

I'd love to hear your thoughts and feedback!

Thanks for checking it out!
