Pricing

Free lets you try Esan with no card required — chat, web search, running code, generating images, memory, and connecting your own apps. Every paid plan gives you every model, including the most capable ones, plus projects, scheduled tasks and agent-to-agent, where your assistants coordinate on their own. The paid plans differ in one thing only: how much you can use. Pro is built for everyday work, Plus is three times that, and Max is for people who lean on Esan all day.

Each plan includes an amount of usage — think of it as a monthly allowance for the work Esan does for you. Heavier tasks use a bit more, lighter ones less, and before a large task Esan tells you roughly what it will use. If you approach your limit you'll see it clearly and can wait for your monthly reset, add more usage, or move up a plan. There are no surprise charges and nothing runs away without you.

Every paid plan gives you the same Esan and the same models. What changes is room: Plus is three times Pro’s usage, and Max is seven or sixteen times, with higher output limits and priority when traffic is high so long, demanding work keeps moving. Max comes in two levels and you can switch between them at any time — the cards above show what each costs where you are. Each step up also costs less per unit of usage than the one below it, so moving up is always the better deal, never a penalty.

Yes, any time, from your settings. Moving UP takes effect straight away — you are charged only the difference for the days left in the month, and the part of the old plan you have not used is credited back. Moving DOWN or cancelling takes effect at the start of your next billing cycle, so you keep what you already paid for until then.
