Connect your Gmail, define your categories in plain English, and let AI sort every incoming email into the right label. No rules. No filters. It just works.
Sign in and connect your Google account. We only request the permissions needed to read and label your emails.
Create labels like “Finance”, “Health”, or “Work” and describe them in plain English. The AI uses your descriptions as its guide.
New emails are automatically categorized as they arrive. Labels show up right in Gmail — any client, any device.
Most email tools force you to pick one label per message. Custoadian applies every label that fits — and when categories overlap, exclusivity groups make sure only the best match in each group wins.
A single email from your accountant about an upcoming trip? It gets both “Finance” and “Travel” automatically.
Group categories like “Personal” and “Work” so only one can apply per email. The AI picks the strongest match within each group.
No regex, no sender lists, no fragile filter chains. Describe what a category means and the AI figures out the rest.
Labels are applied directly in Gmail. See them on your phone, desktop, or any mail client — no extra app required.
