Welcome to the Rasa Documentation!

What am I looking at?

Rasa is a framework for building conversational software: Messenger/Slack bots, Alexa skills, etc. We’ll abbreviate this as a bot in this documentation. You can

  • implement the actions your bot can take in python code (recommended),
  • or use Rasa Core as a webservice (experimental, see HTTP server).

What’s cool about it?

Rather than a bunch of if/else statements, the logic of your bot is based on a probabilistic model trained on example conversations.

That sounds harder than writing a few if statements

In the beginning of a project, it’s indeed easier to just hard code some logic. Rasa helps you when you want to go past that and create a bot that can handle more complexity.

Can I see it in action?

We thought you’d never ask! Make sure to follow the Installation and check out Building a Simple Bot afterwards!
