FAQ
Frequently asked.
Do I need a Telegram account?
Not for tools with a working web interface, such as Translate, Grammar and Summary. Telegram-only products and actions still require Telegram. Linking the same account can carry eligible Pass access across supported surfaces.
How do optional paid actions work?
Web free quotas are separate from Telegram. In a bot, paid actions are paid by card inside Telegram. On vust.ai, the product row names its Tribute card checkout.
Is there a free tier?
Grammar on the web has a bucket of 10 checks and refills by 1 every 4 hours. Other tools use their own limits.
Can I use VUST in my native language?
It depends on the tool: Translate covers 100+ languages via DeepL; Grammar and Humanizer work well for English and Russian and detect the language automatically. Open the hub for the job you need — each page states the languages it supports.
Where does my data go?
Your input is processed to produce the requested result. VUST does not use it to train models. Request records auto-purge after 30 days.
How do I pay?
On vust.ai, choose the Tribute card checkout from the product row; if account linking is required, you return to that same product after linking. If that exact product is unavailable, checkout stays unavailable instead of substituting another price. Plan prices already include Tribute’s payment fee.
Which tools are included?
Translate, Grammar, Rephrase, Markdown, Humanizer, Prompt, Summary, Search, CV, and Word Counter each have a public page on vust.ai. Study runs primarily as @vustStudyBot in Telegram. Capabilities and limits differ per tool — open the hub for the job you need.
Is VUST the same as ChatGPT?
No. VUST provides focused tools with defined inputs and outputs, not an open-ended assistant. Choose the bot or web page for the job and receive the corresponding result without managing models on every request.
What are VUST Passes (Core / Pro)?
A Pass is 30 days of access in one bot. Core, Pro and Max are 30-day recurring access tiers across supported VUST tools. Link Telegram and web to the same account so eligible Pass access resolves consistently.
