One reason why Stably AI is able to perform actions in your app with high accuracy is because it understands your app via a knowledge base of your app.

Stably builds a knowledge base of your web app from your documentation and past test runs.

Simply add links to your user docs in the Knowledge section.

We automatically crawl the documentation and extract the text and images. The indexed is updated daily but you can also manually re-index your documentation.

Test runs

Stably will automatically index the text and images from the screenshots in other test runs.

AI regular app explorations

We have a separate AI agent that proactively explores your app to update its understanding of the app.

Web traffic

You can either install our JavaScript snippet to observe your web traffic or export your PostHog events JSON to Stably.
