A privacy first companion AI
On-device AI companion avoiding Replika's privacy risks by keeping chat data local.

Mr. Relentless actually pushes back instead of endlessly validating — refreshing in AI wellness.
People struggling with motivation, anxiety, or procrastination

We tried the apps. Calm felt like homework and ChatGPT mostly tells how awesome we are and we need to love ourselves like we are, cant agree with that too much
So we built what we actually wanted, tested with ~50 beta testers and felt good about publishing it. Also, publishing this puts us somewhere on the lower slopes of Cringe Mountain, but here we are so please bear with me
ILTY tracks your mood before and after every conversation, so you can tell whether it helped or whether you just had a pleasant interaction with a very confident machine. It has 5 AI companions with different styles. One of them, Mr. Relentless, is for when you need to get your shit together.
Stack: native SwiftUI (iOS 16+), Claude Sonnet 4.6 via Cloudflare Worker proxy, iCloud Documents for storage so user data stays off our servers, RevenueCat for subscriptions, Firebase Analytics exported to BigQuery. Just iOS for now yes.
We’re not new to building products. We come from product design and engineering management in larger companies, but mostly hand-waving on meetings and showing pretty figma prototypes. We started in January and shipped to the App Store in April. ClaudeCode and Gstack by Garry Tan certainly helped a lot :]
ILTY is not therapy. We don’t diagnose or treat. If things get dark, we route to 988, not an AI response.
Happy to answer questions about the build, companion design, prompts, or any of the decisions behind it.
