Both train an AI chatbot on your own documents, but they're built for different audiences. Chatbase is a self-serve developer-leaning tool with usage-based message credits and tiered character limits. AskTheBubble is built for non-technical small businesses, with predictable flat pricing based on website visitors, an optional human-led $500 setup, and stricter answer-grounding to prevent off-topic replies.
It depends on usage. Chatbase Hobby is $40/month for 2,000 messages and 33M characters. AskTheBubble Starter is $50/month based on 250 daily unique visitors with unlimited messages within that traffic tier. For a typical small business website, AskTheBubble is in the same neighborhood with simpler pricing — you don't have to track message credits.
AskTheBubble is intentionally restrictive — it only answers from your uploaded content. If a visitor asks something not covered in the knowledge base, the bot says it doesn't know rather than inventing an answer. Chatbase has similar grounding but its default settings tend to be more conversational and willing to fill gaps with general LLM knowledge.
Yes. AskTheBubble accepts the same kinds of inputs Chatbase does — PDFs, plain text, and website URLs. Most migrations take under 30 minutes: re-upload your existing source files, customize the widget, and swap the embed snippet on your site. The optional $500 setup add-on includes the migration if you'd rather have someone else do it.
Yes. You can customize the widget's color, logo, welcome message, and bubble icon to match your brand. The widget loads via a single JavaScript snippet on any website, regardless of platform — WordPress, Shopify, Webflow, Squarespace, Wix, or custom-built.
AskTheBubble is built for non-developers. The dashboard focuses on uploading documents and customizing the widget, with no tokens, message credits, or model selection to manage. Chatbase exposes more configuration — useful if you want to tune the model, but a barrier if you just want a working chatbot today.
No credit card required. Add the optional $500 setup help and we'll migrate everything for you.
