How zy.ai works
Short reference for the product. No fluff - just what you need to open a chat, pick a model, and get work done.
Getting started
- Go to zyai.org and create a free account (email or Google). Chat requires sign-in.
- Confirm your email if asked, then open the app (/chat).
- Pick a model from the selector, type a message, press Enter.
A free account is required to use the product. No card needed for Free. Upgrade later for higher limits or Pro models.
Chat & models
zy.ai is a single workspace for lab models (Claude, GPT, Gemini, and others) and solid open models. Switch anytime from the model menu - same chat history, same account.
Some models are free-tier friendly; stronger frontier models are on Pro and Ultra. If you select one you don�t have access to, you�ll see the plan screen instead of a dead error.
Tip: match the model to the job. Quick drafts and short answers � faster models. Long writing, careful review � heavier models.
/new - request a model
Missing something in the list? Type:
/new claude sonnet 5
We queue the request for your workspace. No form, no ticket board. When it�s wired, it shows up for you like any other model.
This is for real model names people want to use - not a general feature request channel.
Commands
Handy inputs in chat (type them in the message box):
| Command | What it does |
|---|---|
| /new � | Request a model that isn�t available yet |
| /scan | Start code scan mode (Pro / Ultra) |
| /model | Open or change model (where supported) |
Empty-state chips under a new chat are shortcuts - team summary, calories, softer wording, week plan, and so on. They just fill a useful prompt; edit and send.
Files & voice
Attach files from the paperclip when you need the model to see a document or code file. Large code pastes can get cut off in the box - attach the file instead.
zy.ai is a multi-model chat platform on every plan. Voice mode and business search/answer agents (Deep Research, SEO, company intel, leads, social, news) are Ultra only. Use the Voice button and Tools menu; non-Ultra users see an upgrade path.
Code scan
/scan (and the Scan chip) run a rule-based check on code you paste or attach. It is not a full security audit and it does not burn AI tokens for the scan itself.
- Available on Pro and Ultra
- Output is practical advice: score, grade, findings you can act on
- Free accounts see the upgrade path instead of a full report
Plans
| Plan | Price | In short |
|---|---|---|
| Free | $0 | Core models, history, /new - no card |
| Pro | $15 / mo | Higher daily usage, frontier models, multi-model chat, scan |
| Ultra | $45 / mo | Higher limits + Voice mode + business search agents + Deep Research |
Exact limits can change as we balance load. If you hit a cap, the app says so and offers upgrade - it won�t silently drop messages.
Billing
Card payments go through Lemon Squeezy. Crypto is available via Cryptomus where enabled in checkout.
- Manage card subscriptions in the Lemon Squeezy customer portal (linked from Settings � Billing when active).
- Invoices and receipts come from the payment provider.
- Plan changes apply after payment confirms; if something looks stuck, refresh the app or sign out/in once.
Account
Settings cover profile, plan, theme, and help links. You can sign in with email/password or Google.
Password reset is on the sign-in screen: enter your email, request a link, set a new password from the mail we send.
Limits & fair use
Every plan has daily (or session) usage limits so the service stays usable for everyone. Heavy continuous load may be throttled.
Don�t use zy.ai to spam, attack systems, or break the law. We may suspend accounts that abuse the product or payment systems.
FAQ
Is my chat private?
Chats are stored so you can reopen history. We don�t sell your conversations. Don�t paste secrets you wouldn�t trust any online tool with.
Why did a model fail?
Upstream providers sometimes time out or rate-limit. Try again, switch model, or shorten the request. Persistent failures - email or support channel in the app.
Can I use this at work?
Yes for normal professional use under your plan. For regulated data (health, finance, legal privilege), follow your company�s rules first.
Telegram?
There is a Telegram bot for the same account and limits when enabled. Web remains the full product. Links appear in the app when available.
