KARL Chatbot is a simple-to-use program that you can use to chat with a bot and create its own repertoire.
It comes packed with a simple set of options that can be figured out even by users with little or no experience in computer software.
The installation procedure is rapid and does not require special attention from the user. Once it finishes, you can check out the regular window with the intuitive structure, representing KARL Chatbot's interface.
You can write text in the dedicated box and enable context mode to chat with the bot. The voice belongs to Microsoft Anna, and there are four characters that you can cycle through: Genie, Merlin, Peedy and Robby.
Last but not least, you can teach the bot what to respond to particular questions or affirmations made by the user. There are no other notable options available through this tool. For example, you cannot save the speech to an audio file, or export the reportoire for further projects.
KARL Chatbot is very responsive to commands and runs on a low amount of CPU and RAM, so it does not affect the overall performance of the computer or interrupt normal user activity. We have not come across any issues throughout our evaluation, since the tool did not hang, crash or pop up error dialogs.
Unfortunately, the learning system of KARL Chatbot is not very intuitive. But we must also take into account that the program has not been updated for a very long time. Even so, it works smoothly on newer operating system.
