Frequently asked questions about Corpus
Do you offer a free plan?
Yes, to some extent. Upon signing up, you’ll have one chatbot and 1,000 tokens to experiment with. This is usually enough to get a feel of the platform and see if it suits your needs.
How can I provide Corpus with content related to my company?
Corpus pulls data from your website, Notion, GitHub, Intercom, HubSpot, ZenDesk, Google Drive, Confluence, RSS feed, and databases like Postgres and MySQL. You can upload files in most formats, including PDFs, Markdown, MS Word/Excel, and more.
Is there a limit to how much content I can train a chatbot on?
This depends on your plan’s token credits. For example, the Basic plan provides 5M tokens, which is around 15M characters. Providing more content will enhance the chatbot’s ability to respond to queries accurately.
What are Tokens?
Tokens are the fundamental units AI models use to calculate text length, consisting of groups of characters, including punctuation and emojis. As a general rule of thumb, one token is roughly equal to 3.3 characters of English text.
What defines a chatbot?
A chatbot refers to a project that contains content on a particular topic, capable of replying to inquiries related to that data. You may need chatbots with different knowledge sets for different purposes, like pre-sales or product support.
What is the user limit for my chatbot?
We do not impose any restrictions on the number of people who can interact with your chatbots. Once on your website, all visitors can interact with it.
How long does it take to train the chatbot?
Training time varies based on the number of pages used, but it typically takes just a few minutes.
Can I re-train my chatbot automatically when I update the content?
Absolutely! We offer an API endpoint you can use whenever your content grows or changes. Add it to your content release workflow or use it in a GitHub action to keep your chatbot up to date.
Do Corpus work with non-English content?
Yes. Corpus can understand and respond in several languages, including English, Spanish, French, German, Portuguese, Italian, Dutch, Russian, Arabic, and Chinese, with more languages coming soon.
What happens when the chatbot can’t answer a question?
To ensure accuracy, Corpus delivers answers derived exclusively from your content. If it cannot locate the appropriate response, it will inform the user and recommend contacting you via the contact form available within the widget.
