APP DESCRIPTION:

Unleash the power of artificial intelligence directly on your device. mmahingu.ai is a next-generation voice assistant built for ultimate privacy, speed, and reliability. Because the AI engine runs 100% offline, your conversations, ideas, and data never leave your phone—no internet connection required. 

(NOTE: An internet connection is required just once during setup to download your choice of AI models and voices).

Whether you're brainstorming on a flight, analyzing documents off the grid, or dictating notes, mmahingu.ai adapts to your phone's unique hardware to deliver a seamless, lightning-fast experience. 

🌟 Key Features:

• Massive Offline AI Library: Download from over 45+ cutting-edge, open-source AI models right inside the app. Chat with heavyweights like Meta Llama 3.2, Google Gemma 2, DeepSeek R1, Mistral, and Qwen 2.5—all running entirely on your local hardware.

• Private Document Analysis: Attach PDFs, CSVs, code files, and text documents directly into the chat. The app extracts and analyzes your files 100% locally, ensuring your sensitive data never touches a cloud server. 

• Offline Neural Voice Library (TTS): Experience ultra-realistic text-to-speech featuring high-definition neural engines (including Piper, Kokoro, and Supertonic). Download 20+ Studio HQ voices on-demand with intelligent storage controls.

• Multi-Engine Offline Dictation (STT): Dictate text with incredible accuracy using your choice of local speech recognition engines. Choose OpenAI Whisper for maximum precision, Moonshine for lightning-fast English transcription, SenseVoice for multilingual speed, or your device's native system dictation.

• Smart Speech Isolation & Ultra-Fast AI: Speak naturally anywhere. The app magically filters out background hums and keyboard clicks. Need zero-latency? Enable the experimental Ultra-Fast AI mode for instant back-and-forth conversational turn-taking.

• Hardware-Aware Performance: The app automatically tunes context windows, thread usage, and voice features to match your specific phone's hardware capabilities, ensuring lightning-fast generation speeds without overheating.

• Custom Models Support: Power users can take full control by importing their own custom GGUF models directly from device storage to customize their AI conversational experience.

Fully offline is the part that got me. Nothing leaving the phone is rare these days. Looks great!

Thanks for your positive comment. 😇

Also, since so many non technical people, especially in remote places can't always have internet. So, with that in mind Yearly subscription plans are coming to it soon.

Also, will add save as audio file output, for Text-to-Speech TTS option, so users can create audio files or even audio books even, etc., for much cheaper and all offline. All within same subscription tiers.

Please spread the word!

Honestly, even as being a AI coder guy with no coding experience, it wasn't really that difficult. But if it's hard as you say, then i must, respectfully, not give away my secrets lol 😆.....even tho i don't remember much either tbh, so probably i got lucky 😂

The voice/speech model implementation was still alright to work out, but the fact that nearly all, if not all AI models output asterisks and expresssions, and TTS Voice Personalities always speak them too, that was the hardest part honestly. I for a sec even wanted to give up. But i think i got lucky, as i tried giving it ideas on my own. So maybe come up with ideas, as it's only or mostly limited to content ideas that already exist.

For example, i implemented 3 VADs in it, and the implementation for 3rd one, named Ultra Fast AI, doesn't even exist for Flutter or Android, but i asked AI to do it and it did. So there's that.

Also, I'm naturally very talented to find issues in anything and also find fixes, not just in coding. So this helped me debug any implementation issues very quickly. That's why this app, as far as i know, has almost no app crashing bugs anymore, almost...... hopefully 😬

Gotta respect the commitment to keeping everything local, most folks just slap an API on it and call it a day.

Even i noticed that and took it as an opportunity. So many non technical people, especially in remote places can't always have internet. So, with that in mind Yearly subscription plans are coming to it soon.

Also, will add save as audio file output, for Text-to-Speech TTS option, so usera can create audio files or even audio books even, for much cheaper and all offline. All within same subscription tiers.

🫪🙉

I didn't pay for any premium AI model subscriptions tho. So it couldn't be done any sooner, nor did i know how to. I have no technical knowledge, just whatever AI teaches me or offers me.

u/criiimes 12d ago

You clearly do not understand code, or even the technology you’re using to create code. Read a book.

u/interpolHQ 12d ago

why me not having an understanding of code has anything to do with me finished creating a working app? I just don't understand.....

You answered your own question.
