## What is Yiren AI?

Yiren AI is a fully offline AI translator and study tool. Every AI model runs locally on your device — it works without internet, and your text, photos, voice, and     
chats stay on your phone and are never uploaded to any server.
                                                                                                                                                                        
Features                                                                                                                                                                
· Chinese ⇄ English translation — natural, single-language output, with voice and camera input                                                                          
· AI chat — on-device large language model with selectable personas and automatic long-context handling                                                                 
· Camera translation — snap a photo of text for line-by-line translation                                                                                                
· Voice translation — speak and have it transcribed offline, then translated                                                                                            
· Vocabulary books — paste or import words; AI extracts entries automatically; edit, add, one-tap dedup                                                                 
· Spaced-repetition review (SRS) — daily due cards, streaks, a "hard words" deck, and local reminders                                                                   
· History & favorites — revisit translations, star them into your review pool                                                                                           
· Backup & restore — move all your data in a single file when switching phones                             
                                                                                                                                                                        
Privacy first                                                                                                                                                           
No account, no personal data collection, no ads, no tracking. All AI inference happens on-device.                                                                       
The app only goes online when you choose to download a model or check for updates — it never sends your data.                                                           
                                                                                                                                                                        
About the model                                                                                                                                                         
First-time use requires a one-time in-app download of the offline AI model (~2.4 GB, Wi-Fi recommended).                                                                
After that the app works fully offline, forever.

What’s New
· Added a confirmation prompt before downloading AI models, clearly showing the download size so you can choose whether to proceed                                                                                               
· Faster model downloads outside mainland China with the official CDN source now used by default                                                                                                                                 
· Downloads resume automatically and continue in the background or with the screen locked 
· Much faster model downloads with parallel chunked downloading
· More resilient: each segment resumes independently; downloads continue with the screen locked or the app in the background
