# Hearth > Hearth is a calm inner work app informed by Internal Family Systems (IFS). An AI guide helps a person meet the parts of themselves, the anxious one, the inner critic, the part that shuts down, and lead them from a steady center. Talk or type, a few minutes a day, private. Not therapy, not a substitute for professional care. Hearth is built and written by Billy Barnard, an IFS informed practitioner trained through the IFS Online Circle, not a licensed clinical therapist. Hearth is informed by the IFS model and is not affiliated with, endorsed by, or certified by the IFS Institute or Richard Schwartz. ## Start here - [Homepage](https://little-hearth.com/): what Hearth is, how it works, pricing. - [How to talk to your parts](https://little-hearth.com/how-to-ifs): a beginner's guide to IFS, step by step. - [The IFS model guide](https://little-hearth.com/ifs-model-guide): parts, Self, protectors, exiles, the evidence base. - [IFS glossary](https://little-hearth.com/ifs-glossary): short definitions of every core IFS term. ## Core IFS concepts - [Protectors](https://little-hearth.com/ifs-protectors) - [Managers](https://little-hearth.com/ifs-managers) - [Firefighters](https://little-hearth.com/ifs-firefighters) - [Exiles](https://little-hearth.com/ifs-exiles) - [Self](https://little-hearth.com/ifs-self) - [Unburdening](https://little-hearth.com/ifs-unburdening) ## IFS for specific situations - [IFS for anxiety](https://little-hearth.com/ifs-for-anxiety) - [IFS for depression](https://little-hearth.com/ifs-for-depression) - [IFS and trauma](https://little-hearth.com/ifs-for-trauma) - [Doing IFS alone](https://little-hearth.com/understanding-ifs-alone) - [Hearth app versus IFS therapy](https://little-hearth.com/ifs-app-vs-therapy) - [IFS versus CBT](https://little-hearth.com/ifs-vs-cbt) - [IFS versus EMDR](https://little-hearth.com/ifs-vs-emdr) ## Letters - [Practice notes hub](https://little-hearth.com/letters): first person notes from real IFS informed inner work. ## About - [About Billy Barnard](https://little-hearth.com/about): the practitioner behind Hearth, training background, credentials. - [Work with Billy one to one](https://little-hearth.com/work-with-me): guided one to one inner work outside the app.
