Comments on Caelum - Local AI assistant for Android

★★★★★ Gaven Henderson · Dec 28, 2025

Fantastic app so far, I sense there's some fine-tuning to compliment the smaller output, and It's great to see search functionality in a local AI app!

★★★★★ Max Krone · Apr 7, 2026

This is great. I am assuming it's based off the 1B Gemma model. I wish there was an option to add other models since some phones can handle more.

★★★★★ Michael Walsh · Jan 24, 2026

Lots of local AI apps exist but none are as plug and play as this one. The only area of improvement I'd suggest is having an "about" section that displays which version of Gemma is being pulled and what runtime is serving it (liteRT, media pipe, llama, etc.) I guarantee that even if the app description without any app changes specified model/runtime would make this app get a lot more DLs on the play store, as Gemma bundled without the Apache license doesn't get the attention this deserves.

I installed it, and then when I opened the app there was written 1020mb with a time estimate. When 1020mb finished then It went out from the app automatically, and again I opened the app, it was written again the 1020mb was downloading for several times, and I don't know why, even my phone is Redmi Note 13 with 8 GB RAM +8 GB additional, and 256 storage which I use only 30%. If you read my comment as the developer of the app, do something. Thanks for reading my comment. 💐❤️
