No Signup Required
AI Without the Signup Form.
Use GPT-5.6, Claude, Gemini and Grok with no new email or password: your Telegram account is the login, so there is no registration form. The base GPT-5.6 model is free, and Gemini and DeepSeek each include one free response a day.
Honest scope
One account IS required — your Telegram
"No signup" here means no NEW account. A Telegram account is required — it identifies the chat and keeps the conversation available across your Telegram devices. If you don't use Telegram, this isn't your tool; we'd rather say that plainly than hide it behind an asterisk.
See the difference
The usual signup gauntlet vs the Telegram flow — step by step.
Who no-signup access is actually for
- One-off task users
- Need one paragraph rewritten or one question answered — creating an account for that is absurd
- Open @vustbot, paste the task, get the answer. Total new credentials created: zero. The base GPT-5.6 model is free.
- Signup-fatigued researchers
- Comparing AI tools means five registration forms before seeing five answers
- Here the comparison IS the first message: send the same task, switch models (GPT-5.6, Claude, Gemini, Grok) in one chat, judge outputs side by side.
- Account-minimalists
- Avoid creating another email-and-password login for a one-off task
- Your Telegram account identifies the chat. VUST still processes your Telegram identity and task to provide the answer; no-signup is not an anonymity claim.
From zero to first answer
- 01
Open @vustbot
In any Telegram app — phone, desktop, web. If you're reading this in Telegram, you're one tap away. No 'create account' screen exists on the way.
- 02
Send a real task as a plain message
Rewrite a paragraph, answer a question or draft an email. The bot picks a suitable model and returns the answer in the same chat.
- 03
Switch models when you want a second opinion
GPT-5-class, Claude, Gemini, Grok, DeepSeek, GLM and Kimi are switchable inside the same conversation. Gemini and DeepSeek each include one free response a day; paid model runs show the exact price before confirmation.
The whole signup is one tap
Open @vustbot and send your first task on the free base model. No new registration form stands between you and the answer.
Honest scope — the one gate that exists
A Telegram account IS required
"No signup" means no NEW account: no separate VUST email or password. Telegram identifies the chat and keeps the conversation across devices. No Telegram — not your tool, and we say that plainly.
A defined free tier
The base GPT-5.6 model is free, and Gemini and DeepSeek each include one free response a day. Stronger models and additional runs show the exact price before confirmation — nothing auto-subscribes.
No-signup is not anonymous use
Your Telegram identity and task content still have to be processed to run the bot and generate the answer. The narrower claim is that VUST does not require a separate email-and-password login.
Frequently asked questions
Is it really AI without signup — or signup in disguise?
There is genuinely no registration form: no email field, no password, no phone verification of ours, no card screen. The honest fine print is that you need a Telegram account — that's the login. If you're reading this in Telegram already, you're past the only gate that exists.
Which models can I use without registering?
The @vustbot lineup: GPT-5-class models, Claude, Gemini, Grok, DeepSeek, GLM and Kimi — switchable inside one chat. You don't pick a plan first; send a task, and change models when you want a second opinion.
What's free before any payment?
The base GPT-5.6 model is free for everyday chat. Gemini and DeepSeek each include one free response per day. Stronger models and additional runs are optional paid actions; Telegram shows the exact price before you confirm, and no subscription starts automatically.
Why do most AI sites force signup when this doesn't?
VUST uses your Telegram account as the login instead of creating a separate email-and-password account. Your task still has to be processed to produce an answer, and Telegram presents the exact price if you choose a paid action. The difference is one less registration form, not anonymous AI processing.
Is no-signup worse for privacy than a normal account?
No extra VUST email or password is needed for login. Your Telegram identity and task content still have to be processed to run the bot and generate the answer, so no-signup should not be read as anonymous or data-free use.
Can I use it on desktop, not just my phone?
Yes — anywhere Telegram runs: Windows, macOS, Linux, the web version and tablets. The chat syncs through Telegram, and VUST recognizes the same Telegram identity across those devices.
