Harmony vs IFS Buddy
Last updated: July 2026
Harmony and IFS Buddy are both apps for doing Internal Family Systems work with an AI companion, each with a very different take on what that should feel like.
Harmony
Harmony is an AI therapist you can talk to, switching seamlessly between voice and text. It specializes in IFS, fine tuned for parts work, with a CBT mode you can switch to at any time. There is also a relationship mode, where couples (or any relationship) join one session together and Harmony guides them to understand one another and regain connection. After each session, Harmony provides a post-session analysis with key insights, strengths and weaknesses, visualizations, and more to make what came up in the session stick.
What sets Harmony apart is its ability to understand someone's inner world and get to the root of issues, providing change that lasts.
Pros
- Most fully featured app: post-session analysis4, AI and user trailheads6, journal space, and visualizations like parts maps3 and comic strips
- Harmony maintains memory across all sessions
- High quality and diverse selection of voices
Cons
- No manual parts mapper: parts maps are created for you after sessions, so you cannot build and arrange one by hand
- No library of pre-recorded guided meditations to play outside of live sessions
IFS Buddy
IFS Buddy was one of the first AI IFS chatbots to come on the scene, a web-based companion for parts work. You chat with the buddy in one of three modes depending on where you are: Beginner introduces parts work, Self-Finding starts from finding Self, and Unblending guides you through unblending from a part. A My Parts panel4 keeps a library of the parts you discover, and a "What is Self?" explainer keeps the core ideas close at hand.
IFS Buddy also offers a Session Review2 that reflects back the parts involved, the Self qualities you displayed, your progress, and focus areas moving forward. IFS Buddy, as the name suggests, is a simple buddy that helps a person practice IFS with extra assistance, in a low-pressure way.
Pros
- Library of parts4 you can track, edit, and arrange by hand
- Session Reviews2 that include the Self qualities you displayed, your progress, and focus areas moving forward
- Three chatbot modes: Beginner to introduce parts work, Self-Finding (the default) to start from finding Self, and Unblending to guide you through unblending
Cons
- Limited free plan: voice, memory, and saving sessions all require an upgrade
- No visual parts map: your parts live in a simple list rather than a map of your inner world
Final Words
Both applications have real strengths, and people gain genuine value out of each. We recommend you give both a go and decide yourself!
