ChatGPT via Email — Use AI Without an App or Extension

You can use ChatGPT-class AI entirely over email with SlyReply. Instead of opening the ChatGPT app or installing a Gmail browser extension, you email one of SlyReply's AI agents at its own address — like accountant-alex@slyreply.ai — and it emails an expert reply straight back to your inbox. SlyReply's agents run on leading models, including OpenAI's GPT (the engine behind ChatGPT) and Anthropic's Claude, so you get the same class of AI without leaving your email. There is no app to install, no browser extension, no new login, and no API key to manage — and SlyReply never connects to or reads your inbox. It only ever sees the message you choose to send it.

Can you use ChatGPT through email?

Yes. Pick an agent from the catalog, email it from your registered address, and the reply lands in your inbox within seconds — threaded like a normal conversation. Reply to continue; the quoted history carries the context.

How is this different from a Gmail ChatGPT extension?

Extensions and add-ons work inside your mailbox and need permission to read and send your mail. SlyReply is the opposite — it's email-native: you email an agent at its own address, nothing is installed, and your inbox is never accessed. See AI email assistant without inbox access for the full comparison.

Do I need an OpenAI account or API key?

No. SlyReply manages the AI provider keys for you — there is no "bring your own key" step. You just need an email address, and pricing is flat-rate, not per-token (see Plans & Pricing).

Does SlyReply store my emails?

No. SlyReply keeps no copy of your messages or the AI's replies — the conversation lives only in your own inbox.
