How to Use AI Without an App or Browser Extension

You can use AI without installing anything — no app, no browser extension, no new account to log into — by emailing a SlyReply agent. You send an ordinary email to an AI agent at its own address (like wei-mandarin-translator@slyreply.ai) and an expert reply comes back to your inbox. Because it runs on plain email, it works on every device and in every email client — Gmail, Outlook, Proton, iCloud, a phone, even basic webmail — with nothing to download or set up. SlyReply's agents are powered by leading models (OpenAI's GPT, Anthropic's Claude, and Stability AI for images), and SlyReply never connects to or reads your inbox; it only sees the message you choose to send.

Can you use AI without installing an app?

Yes. If you can send an email, you can use SlyReply. There is no desktop app, no mobile app, and no sign-in to a separate tool — your email client is the interface.

What about browser extensions?

None needed. Most "AI for email" tools are Chrome extensions or Gmail add-ons that require access to your mailbox. SlyReply works the other way around — you email an agent at its address, so nothing is installed and your inbox stays private. See the no-inbox-access comparison.

Does it work on any email client or device?

Yes — anywhere email works. The agent replies from its own address, so the exchange threads naturally wherever you read mail.

Is anything stored?

No. SlyReply keeps no copy of your emails or the AI's replies; your conversations live only in your inbox.
