What you can do
Write a first draft. Untangle an idea. Ask a follow-up. PhoneGPT runs downloaded AI models on your phone, with tools that keep you in control of the conversation.
Find your first steps →01 / Make room for ideas
Ask for an explanation, try a different wording, or turn a rough thought into a plan.
Replies appear as the model generates them. You can stop a reply and type your next draft while it works. 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 personal memory.
Small tools, everyday uses
English voice typing
Download a separate Whisper voice model, then dictate into the message box. Transcription runs locally and updates as you speak. Review and edit the words before you send them.
English only. Transcription speed varies by phone and model. Replies are text; spoken replies are not available.
TXT questions
Attach a plain-text .txt file up to 32 KB. Ask for a summary, pull out action items, or discuss a passage, as long as the text fits within the model’s conversation limit.
Attachments currently support TXT only. Images, PDFs, Word documents, and scanned pages are not supported.
02 / Pick what works for you
Browse models from Qwen, LLaMA, SmolLM, DeepSeek, and Gemma. Download one, load it, and switch between installed chat models without clearing your conversation.
Pause, resume, cancel, or delete model downloads. Chat and voice use separate models, so you only need a voice model if you want to dictate.
Download size tells you how much storage a model needs, not how much working memory it uses. Larger models and using more conversation history for each reply can exceed your phone’s available memory.
03 / Keep a comfortable rhythm
Reopen locally saved conversations and search their titles and messages. Delete an individual chat with a confirmation step.
Choose a light or dark theme and adjust text size across the app. Select and copy text from formatted replies.
Save instructions for new chats, adjust reply length and how much conversation the model uses, and choose how much it reasons before answering where supported. Options depend on the model and your phone’s memory.
A useful distinction
After installing the app and downloading your models, chat and English voice typing work on your phone without internet.
New downloads need internet. Answers can be wrong, and a local model does not fetch live information. Cloud backup and accounts are not available in the current app.
