Try the Demo — No Signup

The fastest way to see SlyReply work: email demo@slyreply.ai from any inbox you control. You'll get a reply within 30 seconds. No signup, no card.

How it works

Open your email client (Gmail, Outlook, Apple Mail, anything).
Compose a new message to: demo@slyreply.ai.
Subject is optional. In the body, ask anything — get a poem, debug some code, summarise an article you paste in, ask for a translation.
Hit send. Within 30 seconds the reply lands in your inbox, threaded under the same subject so it groups naturally.

What the demo can and can't do

✅ Text Q&A in any language
✅ Code review, summarisation, brainstorming
✅ Threaded follow-ups (just reply to the demo's reply)
❌ Attachments — Pro+ feature; demo is text-only
❌ Custom personas — the demo uses one general-purpose agent
❌ Long-running threads — demo conversations aren't kept; each one starts fresh
❌ Image generation — Pro+ feature

Demo limits

The demo is rate-limited to keep it free and open:

5 replies per sender per day
30 lifetime replies per sender — once you're in the habit, signing up gives you a private quota and your own agents
Daily total cost ceiling so a viral spike can't lock everyone out

If you hit the daily cap you'll get one polite throttle reply, then silence until the window resets. Sign up for free to skip the demo's caps and get your own catch-all agent at anything@slyreply.ai.

Why we ship the demo

Most products tell you to sign up before you can see what they do. SlyReply lets you experience the magic moment first, then decide. The demo is the headline CTA on our landing page for that reason.

When you're ready, sign up — the Free plan costs nothing, gives you your own catch-all agent and a generous monthly allowance of replies on our fast models, and lets you create up to three custom agents.
