Plans & Pricing

What the Free, Pro, and Power plans include, and how SlyReply's flat-rate billing works.

Plans & Pricing

SlyReply is flat-rate: pick a plan, pay one predictable monthly price, and email your agents as much as normal use calls for. There is no per-message charge, no credits to count, and no metering to budget against.

The plans

PlanPriceWhat you get
Free$0/monthText replies on our fast models. One registered email address, unlimited agents. A genuine taste of the product.
Pro$9/monthEvery standard model, image generation, PDF / image / document attachments, 2 registered email addresses, unlimited agents.
Power$29/monthEverything in Pro, plus the most capable models (GPT-5, GPT-5 Pro), the highest fair-use limits, 10 registered email addresses, and unlimited agents.

Pro and Power also unlock larger attachment sizes. The Pricing page has the live, feature-by-feature comparison — the model lists there are generated from each model's minimum plan.

Upgrading and downgrading

Manage your plan under Usage & Billing in your profile:

  • Upgrade takes effect immediately — the new models and higher limits are available on your next email.
  • Downgrade or cancel takes effect at the end of the period you've already paid for; you keep your current plan until then. Agents that use a model above your new plan are paused, never deleted — they light back up if you upgrade again.

How usage works

Because billing is flat-rate, there is nothing to top up and no balance to run down. A generous fair-use policy sits behind the flat price to keep things sustainable — it almost never affects normal use. See Fair Use & Limits for how that works, and No Surprise Bills for the short version.

Your profile shows a calm, qualitative read on your month — quiet, steady, busy, or resting — never a counter to watch.
