07 Your rules

An assistant, not a bot.

Diplio helps you write — it never takes over your conversations.

Never auto-sends. You always pick the reply and hit send yourself.
Never stores your chats. Context is used once to write your reply, then discarded.
No bot replies. Diplio suggests — you decide. It's a writing assistant, not an auto-responder.
Never sold or trained on. Your messages are never sold or used to train models.
08 FAQ

Questions, answered.

What is Diplio?
Diplio is an AI reply assistant. In WhatsApp, Gmail, Outlook, LinkedIn and X it adds a button that reads the open chat or thread and drafts three ready-to-send replies in your tone and language — plus summarize, compose and translate. There's also a web app for rewriting any message.
How is it different from other reply tools?
Most tools only look at your last message. Diplio reads the whole conversation — including photos and PDFs shared in the chat — and learns how you write, so the replies actually fit the situation and sound like you.
Does it store my messages?
No. Your conversation is used once to generate the reply, then discarded. Nothing is stored on our servers, sold, or used to train models.
Will it send messages for me?
Never. Diplio only writes suggestions and inserts the one you pick into the message box. You always press send yourself.
What languages does it support?
100+. It detects the chat's language and replies natively — real slang and rhythm, not a stiff translation. You can also force a specific language.
Is it free?
Yes — start free, no card needed. Premium unlocks unlimited replies.
