When to choose Chatbase instead
- You need PDFs, other files, Notion pages or help desk tickets as sources, not only public web pages. Docapta cannot do this; choose Chatbase.
- You want AI actions, such as checking order status or changing a subscription, or answers in Slack, WhatsApp, Messenger, email or voice. Docapta does none of these.
- You prefer a native WordPress plugin to pasting a script snippet.
- You expect far more than 500 questions a month; Chatbase plans go up to 15,000 message credits per month on Pro before Enterprise.
When Docapta is the better fit
- Your answers should come from your public plugin documentation, with a link to the page each answer used.
- You want a predictable monthly price measured in questions, with usage that stops instead of automatic overage charges.
- Account, payment and refund questions should go to your human support channel, not to an AI agent that changes accounts.
How to switch to Docapta
1. Subscribe and create your assistant
Register, verify your email and subscribe to the $39/month plan from the pricing page. Create one assistant and add your support contact.
2. Import your public documentation
Add the public HTTPS documentation URLs you want answers to come from (up to 50 HTML pages). Wait for indexing, then test real questions in the dashboard and open the linked sources.
3. Install the widget on WordPress
Save the exact HTTPS website, copy your embed snippet and paste it once in a site-wide footer area, for example WPCode Header & Footer.
4. Verify, then remove the old chatbot
Open a published page while logged out, ask one documented question and follow its source link. Once it works, remove the previous widget or plugin so visitors see only one chat launcher.
Questions about switching
Is Docapta cheaper than Chatbase?
It depends on your volume and plan. Docapta is $39/month for 500 questions. Chatbase Hobby is $32/month billed yearly for 700 message credits per month. Check how many credits your Chatbase setup uses per answer, and compare against your actual monthly question count.
Can Docapta import PDFs, Notion or help desk tickets?
No. Docapta imports public HTTPS HTML documentation pages only. If those sources matter to you, Chatbase lists files, Notion and tickets as training sources.
Does Docapta have a WordPress plugin like Chatbase?
No. You paste one JavaScript snippet into a site-wide footer area, for example with WPCode. The installation guide shows each step.
Can I test Docapta before replacing Chatbase?
Yes. After subscribing you can import your docs and test answers in the dashboard before adding the widget to your site. Dashboard checks count toward the 500-question allowance.
Are Docapta answers always correct?
No AI answer is guaranteed. Docapta links the source page for each answer so visitors can check it, and sends account, order and refund questions to your support channel.
Try Docapta on your own documentation
One plan: $39 per month for one assistant on one website, up to 50 public HTML pages and 500 questions per trailing 31 days. Usage stops at the limit; there are no automatic overage charges.
