Room for your train of thought.
Read replies as they appear, keep a conversation going and find your way back with searchable local chat history.
A little AI that lives on your phone.

No mandatory account · Models downloaded separately
Let’s keep it simple.
Take a street you’ve never walked. Bring a notebook. Find a tiny café and give yourself an hour with no plans.
Sometimes, that’s plenty of adventure.
Replies generated by your phone.
Download once. Keep the conversation going.
Choose your model. Find your fit.
WHY PHONEGPT?
Not every thought needs a trip to a server.
PhoneGPT puts a compatible AI model on your own phone. Ask a question on a flight. Work through an idea on a walk. Discuss a text file without uploading it to a chat service.
After your app and models are downloaded, chat and voice typing happen locally. No mandatory sign-up. After setup, you can chat without internet.
Understand what stays localSMALL APP. ROOM FOR A LOT.
Read replies as they appear, keep a conversation going and find your way back with searchable local chat history.
English voice typing turns speech into an editable draft, using a separately downloaded Whisper model.
Transcribed on your deviceAttach a small .txt file, then ask a question about it. The contents are read locally for your conversation.

WHO’S IT FOR?
You don’t need to know how a model works.
Just bring something you’re curious about.
Brainstorm a weekend project, unpack a concept or find a new angle on something you’re writing.
Bring a downloaded assistant along for the flight, commute or quiet spot with unreliable reception.
Try compatible local models, adjust reply length and how much conversation the model uses, and see what feels right on your device.
Small models can make mistakes. Treat replies as a starting point and verify important information.
THREE SMALL STEPS
Install the PhoneGPT Android app.
You’ll need internet and enough free space.
Start a chat. After setup, try it offline.
Yes. Download and load the models you need first, then chat and use English voice typing without internet. You’ll need a connection for downloads and app updates. No PhoneGPT account is required.
Get the Android app from the Downloads page. Open Models, choose a small model, download it and tap Load. Then open Chat and ask your first question. Our getting-started guide walks you through it.
Start small. Qwen 3.5 0.8B has a Preferred badge as a suggested first model. You can try others from the library to find what suits you and your phone. Voice typing uses a separate English Whisper model.
PhoneGPT needs Android 7.0 or later and a compatible 64-bit phone. You also need enough free storage for your models and enough phone memory to run them. Bigger models need more resources, so start with a compact option. Speed and compatibility vary by device.
Follow-up questions use the current conversation, within your chosen model’s limits. Saving a chat does not give the model unlimited memory. Separate chats do not share their history. You can adjust how much conversation a model uses in Settings; larger settings need more phone memory.
Yes. Download an English voice model, then tap the microphone and speak. Your words appear in the message box, ready to review and edit. Stop finishes the recording; Cancel discards text still being processed. Voice typing doesn’t send your message automatically, and replies are currently text only.
You can attach a plain-text (.txt) file up to 32 KB, as long as its text fits within the model’s conversation limit. Some text formats may not be readable. The app saves a copy with your chat; deleting the chat removes that copy, not your original file. Images, PDFs and Word documents aren’t supported yet.
Not yet. PhoneGPT is currently available for Android. iPhone support is planned, but there is no iPhone download yet.
Check the Downloads page for the latest version and install it over your existing app. Updates aren’t automatic. Avoid uninstalling first: uninstalling or clearing app data removes local chats and downloaded models. Keeping data through every update cannot be guaranteed; PhoneGPT’s own backup feature isn’t available yet.
Use the Say hello form for feedback, ideas, model requests or anything you’d like to say. For a model request, include its name or link. If something went wrong, tell us what happened and which phone you use. Share only what you’re comfortable sending.
