Comments on Caelum - Local AI assistant for Android

★★★★★ 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.

★★★★★ 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!

★★★★☆ R Thomas · Mar 21, 2026

This is a great app, very simple and easy to use. My only suggestion is the option of some downloadable AI models. I understand this very small model is great for most people, but I would love to use bigger models.

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. 💐❤️
