Starting today, 19 October 2026, Essevin subscriptions are open. One monthly plan, priced in Hong Kong dollars, gives you Claude, GPT, GPT Image and leading video models from a single shared pool of credits. You can chat, create images and make short videos in the browser, or create an API key and use the same plan in Claude Code, Codex and other tools.
This post covers what Essevin is, which models are included today, what each plan costs, how to start, how payment works, and how to cancel. Everything here matches the plans on essevin.com and the Terms of Service.
What Essevin is
Essevin is a consumer AI subscription. Instead of keeping separate accounts and overseas cards for each AI service, you have one account, one plan and one monthly bill in HK$.
Every plan works the same way. Each month you receive a pool of credits, and chat, images and video all draw on it. Credits reset every month and do not carry over. You pay a fixed price for the month: there is no pay-as-you-go balance, no top-up and no per-token bill, and the console shows what every request used.
You can use your plan in three places:
Chat in the console: talk to Claude and GPT models in the browser, with nothing to install.
Studio in the console: generate images, and on plans that include video, make short clips.
API keys: point Claude Code, Codex or another Anthropic- or OpenAI-compatible tool at Essevin, and its requests draw on the same credits. The quickstart walks through it.
Models included today
| Family | Representative models | Plans |
|---|---|---|
| Claude | Claude Opus 5.5, Claude Sonnet 5.5, Claude Haiku 5.5 | All plans |
| GPT | GPT-6.1 Sol, GPT-6 Sol, GPT-6 Luna | All plans |
| GPT Image | GPT Image 2, GPT Image 2.5 Flare | All plans (Taster: up to 20 images a month) |
| Video | Seedance, MiniMax Hailuo H3-Max, Wan 3.0 | Everyday, Advanced and Professional |
That is the whole line-up; nothing else is included. The Models page in the console shows exactly what your account can use at any moment, and the models reference explains how to check from an API key.
Plans and prices
| Plan | Monthly | Yearly | Credits per month | Video | Per-message cap |
|---|---|---|---|---|---|
| Taster | HK$28 | HK$288 | 250,000 | No | 10,000 |
| Everyday | HK$128 | HK$1,308 | 1,000,000 | Yes | 30,000 |
| Advanced | HK$288 | HK$2,938 | 2,600,000 | Yes | 60,000 |
| Professional | HK$588 | HK$5,998 | 5,600,000 | Yes | 120,000 |
10,000 credits equal HK$1 of plan value, so every allowance is easy to read. A yearly plan is billed once and issues the monthly allowance every month for twelve months; it is not one large annual pool. The per-message cap is the most a single request can use: a very long answer is shortened rather than billed past it.
What a month covers, roughly, if the whole month goes to one kind of use:
Taster: about 141 Claude Opus 5.5 messages, or about 776 GPT-6 Sol messages, or about 145 Codex requests. Up to 20 images a month; no video.
Everyday: about 564 Claude Opus 5.5 messages, or about 3,105 GPT-6 Sol messages, or about 127 GPT Image 2 images, or about 20 Seedance 2.0 clips.
Advanced: about 1,468 Claude Opus 5.5 messages, or about 8,074 GPT-6 Sol messages, or about 330 GPT Image 2 images, or about 53 Seedance 2.0 clips.
Professional: about 3,162 Claude Opus 5.5 messages, or about 17,391 GPT-6 Sol messages, or about 711 GPT Image 2 images, or about 114 Seedance 2.0 clips.
These are estimates. A message here is 3,000 input and 800 output tokens, an image is 1024×1024 at medium quality, and a clip is 480p and 4 seconds long; real requests are charged by what they actually use. The subscription details page lists every assumption.
If a month runs short, you can add a one-time credit pack while your plan is active: HK$20 for 150,000 credits, HK$50 for 400,000 or HK$100 for 850,000. Pack credits work in the month you buy them and the next month. Taster can buy only the HK$20 pack, up to two a month; the other plans up to ten.
How to start
Create an account. Sign up at console.essevin.com. Registration is free.
Choose a plan. Open Subscription in the console, pick monthly or yearly billing and choose a plan. The price and renewal terms are shown before you pay.
Pay by card. Checkout takes you to a secure payment page. Your plan starts when the first charge is confirmed, which under our payment provider's schedule is normally the calendar day after you complete checkout (Hong Kong time).
Start working. Open Chat or Studio, or create an API key for Claude Code or Codex.
Payment
Prices are in Hong Kong dollars. Subscriptions are paid by credit card and renew automatically every month or every year until you cancel. You enter your card details on our payment provider's checkout page; Essevin never receives your full card number or security code. Credit packs are one-time purchases and can also be paid with the other methods shown at checkout.
Cancel anytime, from the console
You can cancel your renewal yourself, at any time, on the Subscription page in the console. Cancelling stops the next charge. Your plan stays usable until the end of the period you have already paid for, and you receive an email confirming the date it ends. Amounts already charged for a partly used period are not refunded, except where the Terms of Service say otherwise.
If you cannot use the console for any reason, email [email protected] from your account email before your renewal date and we will cancel it for you.
Is Essevin right for you?
Essevin fits well if you use Claude or GPT every week for writing, research or coding, sometimes need an image or a short clip, and would rather have one predictable bill in HK$ than several separate subscriptions.
It is not the right choice if you need a model that is not in the line-up above, or if several people want to share one account: individual plans are for one person, and sharing an account or API key is not allowed under the Terms.
FAQ
Is there a free trial?
No. Creating an account is free, but using the models needs a plan. The smallest plan, Taster, is HK$28 a month and can be cancelled at any time.
When does my plan start?
When the first charge is confirmed, normally the calendar day after you complete checkout, Hong Kong time. A payment that is not confirmed does not start a plan.
Do unused credits roll over?
No. Plan credits reset at the start of every monthly window and do not carry over. Credit pack credits last for the month you buy them and the next month.
Can I use it in Claude Code or Codex?
Yes. Create an API key in the console and follow the quickstart; requests then draw on your subscription credits.
Can I change plans later?
Yes, in the console. When you upgrade from a monthly plan, you buy the new plan and the unused value of the old one is refunded to your card. Downgrades and changes from yearly to monthly billing take effect at the end of the current paid term. The exact terms of each change are shown before you confirm.
