Where the idea came from
IdentityPractice was inspired by a simple writing experiment
described by Shopify co-founder Tobi Lütke: choose something you want to change about yourself, write a corresponding
identity sentence repeatedly for seven days, then compare how true it feels with
where you started.
This app is my practical interpretation of that idea. It adds a clear daily
structure, optional proof actions, progress tracking, and an end-of-week
comparison. IdentityPractice is not affiliated with or endorsed by Tobi Lütke
or Shopify.
Identity first. Behaviour second.
The identity is the north star. The repeated sentence is a practical route toward
it, and an optional proof action gives the idea a place in ordinary life. AI
suggestions explain that relationship rather than replacing the identity you
chose.
Does it need AI, and where is my writing stored?
Does the app require AI?
No. You can write your own supporting sentence. AI suggestions are optional and
use your own provider key.
Is my writing stored in the cloud?
No. Practice data is stored locally on your Mac. If you use AI suggestions, only
the text you submit is sent to your selected provider.
What experimental means
IdentityPractice is an experiment, a quick build on an idea that I wanted to try
for myself, which I am sharing with members. I may not continue to support it in
the way I do the apps built for specific needs, and versions you downloaded during
a paid membership period can still be used if that happens, as long as that period
was not refunded.
Membership and updates
Is IdentityPractice sold separately?
No. IdentityPractice is only available with the membership.
What's changed in the latest version?
