Replyless

Replyless takes a different angle from the usual "AI sidecar bolted onto Gmail." It is an AI-native email app in its own right, but it still sits on top of the mailbox you already use. Gmail, Outlook, and Zoho Mail accounts are connected and merged into one list, with actions syncing back to the provider so your mail is never locked in.

The core idea is forced clarity. Focus mode turns a single noisy inbox into two tabs: Primary for people and threads that need a reply, and Everything else for receipts, newsletters, and promotions. You can also create named views such as Clients, Newsletter, or Payments. Sorting corrects itself as you move things, and urgent emails are pushed to the top of each view. Pressing Command-K opens a command centre for jumping to a view, drafting a reply, or setting a reminder.

AI does the writing and the routine work. Replyless reads the entire thread before drafting an answer in your voice, learns from your edits, and keeps saved snippets ready in the compose toolbar. Beyond that, agents can run background jobs you describe in plain language - a morning digest of unread mail, calendar, and open loops, or pushing invoices to Slack or Notion. Replyless is available on web, macOS, iOS, and Android, keeps each account's data scoped to its own connection, and states that it is GDPR compliant. It is an independent product and is not endorsed by OpenAI, Anthropic, or Google.
