I wanted to share OpenHelper AI, a completely free and open-source AI assistant powered by the HybridAI Intelligence 2.0 engine. It is fully optimized for Windows PCs, Android phones, tablets, foldables, and web browsers.

If you are looking for an elegant, tracking-free alternative to bloated AI applications, this app provides unlimited usage of the latest models with zero ads.

Key Features:

HybridAI Intelligence 2.0 Engine: Supports natural, intelligent conversations with multi-turn context, conversation memory, and fast streaming responses.
Modern Google Material 3 Expressive UI: Built with adaptive layouts that look great on any screen size, complete with Material You Dynamic Color and an edge-to-edge dark theme.
Privacy & Efficiency: Zero ads, zero tracking, and absolutely no unnecessary permissions required.
Cross-Platform Flexibility: Runs natively on Android (Kotlin/Jetpack Compose) and Windows (Electron), alongside a universal Web version.

The project is fully licensed under the MIT License, and the source code is completely transparent. I would love to hear your feedback on the streaming speed, UI layout, or feature requests!

[APP][OS][10.0+] Ambient Calculator - World's Lightest Open-Source AI & OCR Math Tool

Hey everyone,

I wanted to share Ambient Calculator, a 100% open-source, ad-free math tool built completely with Kotlin and Material 3 for Android phones, tablets, and foldables.

If you are tired of bulky calculator apps loaded with trackers, this is designed to be the exact opposite.

Why try it?

Incredibly Lightweight: The Minimal Edition is only 1.8MB, beating OpenCalc (~2.2MB) and Fossify (~3MB).
Offline AI OCR: Scan complex math problems to instantly get results 100% offline.
Privacy First: Zero ads, zero tracking, and absolutely no permissions required for the minimal version.
Beautiful UI: Full support for Material You dynamic theming, AMOLED dark mode, and dual-panel tablet layouts.
Extra Features: Includes a handwriting-to-math preview, scientific mode, history, and a quick settings tile.

The project is licensed under the MIT License. I would love to get your feedback on the UI layout, OCR speeds, or any features you think are missing!
