How to choose

Which knowledge sources can it use?

Check the listed knowledge sources and source limit against the information your bot needs to answer from. A limit can affect whether your planned material fits.

Can it show where an answer came from?

Check whether answer citations are listed if readers need to trace a response to its source. Compare this alongside the sources the bot can access.

Where does the knowledge bot run?

Compare deployment options with the way people will use the bot. Available platform types include web, API, iOS, Android, browser extension and self-hosted.

Can I control access to its knowledge?

Check the knowledge access controls for the boundaries you need. Compare those controls with the source material and the people who will use the bot.

How do I compare plans and prices?

Look for a free plan, a trial and the stated paid starting price. Pricing on request means you need to ask the provider for a quote; it does not give a public starting price.

Does it support the languages I need?

Compare supported languages with the languages your users will ask questions in and your knowledge material uses.

Questions

What should I look for in a knowledge bot?

Compare its knowledge sources, source limit, answer citations, deployment, supported languages and knowledge access controls. Then check plans and pricing.

How can I tell if a knowledge bot has an API?

Check its platform information for API access. The API mark indicates whether a public API is listed.

What does the free-tier mark mean?

It indicates whether a free tier is listed. Check the provider's plan details to understand what is included.

What does the signal score mean?

It is a score out of 10 based on maker-published information about use, public API access, documentation depth, open-source code and a free tier.

How do I know if a bot can cite its answers?

Check its answer citations information. This tells you whether citations are listed as a feature.
