Frequently asked questions

Try it free
Is Tự Thiết Kế Web free?

Yes. On sign-up, every account gets a one-time 5 page generations and 15 AI edits, no card required. The drag-and-drop editor, publishing to an HTTPS subdomain and connecting a custom domain are all free. Credit packs start at 49.000đ.

How long does it take to create a page with AI?

Usually about 3–8 minutes, depending on page length and the queue, because the AI runs on our own server. Requests run in the background, so you can close the tab and come back later. Creating a single section takes only about 1 minute.

Can I create pages in English or in both languages?

Yes. When creating a page (with AI or from a template), choose Tiếng Việt, English or Bilingual. Bilingual pages have a VI/EN switch for visitors (Vietnamese by default, the English version at /en), and you can edit both versions in the editor. Bilingual pages take longer because the AI also translates; using a template in English or bilingual costs 1 extra AI edit credit.

Can I edit the page after the AI creates it?

Yes. The drag-and-drop editor lets you edit text directly, replace images, change colors, fonts and spacing, add sections from the template library, or ask the AI to revise with a one-sentence request. Undo, drafts and mobile preview are included.

Can I edit pages on my phone?

Yes. On small screens the editor switches to a phone layout: tap text or an image to show the action bar (edit text, change image, AI, move, duplicate, delete); the bottom tab bar opens the section library, blocks, type & color styles, settings and SEO; tap a block to insert it right after the selected part. Tap 💾 to save and ⋯ to publish.

Can I use my own domain?

Yes. Every page comes with a free subdomain like your-page.tuthietkeweb.com. If you have a domain, open the Publish dialog → "Custom domain" tab, add the DNS records as instructed (a TXT verification record and a CNAME to custom.tuthietkeweb.com), then click Check DNS.

How are AI credits counted? What happens when I run out?

Free credits are used first; when they run out, buy a credit pack to continue. Each page creation (or regeneration) uses 3 credits, each AI edit or AI section uses 1 credits. Purchased credits never expire. Failed or cancelled AI requests are refunded. Each account can store up to 20 pages and publish 5 pages at the same time.

Where do I see contact form submissions from my page?

Messages from the contact form on a published page are stored in Received contacts (/lien-he-nhan-duoc; My pages shows the number of new messages) and sent to your account email. You can reply by email, mark them as read or delete them.

How do I pay for more credits?

Pay via payOS with a VietQR code or a bank transfer from any bank in Vietnam. Credits are added automatically as soon as the payment succeeds; every transaction is listed in Transaction history. Credit packs start at 49.000đ.

Do I need coding or design skills?

No. Just describe your business in a few sentences; layouts, colors and fonts are already designed into the themes. If you know HTML/CSS you can still view and edit the code when needed.

Are pages SEO-friendly and mobile-ready?

Yes. Published pages automatically include a title, description, share image, structured data (JSON-LD), sitemap and robots.txt, all editable in the SEO panel. Every section is responsive. In our tests, published pages scored 100 for SEO on Lighthouse.

Is the AI-written content accurate?

The AI writes from your description and only uses phone numbers, emails and addresses found in it. Double-check prices, opening hours and contact details before publishing – you always have the final say.
