Local LLM: Private Offline AI

Local LLM is an AI assistant that runs entirely on your phone. Your chats, documents and voice never leave the device: no account, no cloud, no tracking. Once a model is downloaded, it works in airplane mode.

ASK YOUR OWN DOCUMENTS
Add PDFs, notes and text files to your Library, and get answers that quote the right passage, with the source shown under each reply. Scanned PDFs and photos of documents work too: text is recognised on the phone, so receipts, forms and printed lists become searchable.

TALK TO IT
Voice mode lets you have a hands-free conversation: speak, hear the answer, and interrupt at any time. Dictate messages instead of typing, or have any reply read aloud. Speech is recognised and spoken on the device.

READY ON FIRST LAUNCH
On phones with Gemini Nano built in, you can start chatting straight away with nothing to download. On other phones, Local LLM recommends a model that fits your phone's memory and downloads it once. Downloads resume if your connection drops and continue in the background.

MODELS CHOSEN FOR PHONES
A curated set of current open models (Qwen, Gemma, LFM, MiniCPM and more), each checked to run well on mobile. The app shows which ones fit your phone, how much storage they need and how capable they are. Some models can also understand photos you attach.

GOOD AT EVERYDAY ARITHMETIC
Tips, percentages and sums are worked out exactly with a built-in calculator, so small models don't guess at numbers.

YOUR CHATS, ORGANISED
Pin important conversations, rename them, and export any chat as Markdown or PDF to share or keep. Start a new chat or a voice conversation from the home screen widget or a Quick Settings tile.

PRIVATE BY DESIGN
• Runs on your phone, with no servers involved in your conversations
• No account, no ads, no analytics
• The only network use is downloading models you choose
• Delete a model or a chat at any time, and it's gone

WHAT YOU NEED
Local LLM runs on most Android phones from the last few years. Models range from about 0.7 GB to 3.7 GB; phones with 6 GB of memory or more give the best experience, and smaller models work on 4 GB phones.
