AI inference, chat history, and recognition of attached photos all happen on your device after you download a model file. Message bodies are never sent to our servers.
Every chat is processed locally on your phone, no internet required. Inference and chat history aren't sent to external servers or the cloud.
Conversation text, prompts, AI responses, persona settings, and memory contents aren't sent to our servers or any external AI API.
Download a model once, and chatting and history viewing keep working — even in airplane mode.
Grab one model file built on an open-source language model. Choose between a standard and a high-spec model. (Wi-Fi recommended.)
Start from the default presets, or build your own persona — name, personality, speech style, and background, just the way you want.
Talk on-device with no internet. The more you chat, the closer you grow — and important memories build up over time.
An inference engine built on an open-source language model generates replies directly on your device — no cloud, no external API.
Set the name, personality, speech style, likes, dislikes, and background story however you want. Start from the default presets or create as many personas as you like.
The more you talk, the closer your character feels — and important facts, promises, and emotional context are saved as long-term memory. You can edit or pin key memories yourself.
Attach a photo and your character responds based on what's in it. Recognition is 100% on-device, and photos are never sent anywhere. Photos are picked via the system photo picker, so no extra permission is needed.
The local database is encrypted, and PIN and biometric app lock are supported. Built for ages 16+ with safety filters in place, and message bodies are never sent to our servers.
Export an encrypted .reppo backup file to move or archive your data across devices. Only you, with the backup password, can open it.
Devices with less than 6 GB of RAM are not supported for chat. The standard model recommends 6 GB+ RAM and the high-spec model recommends 12 GB+; keeping multiple models needs additional storage accordingly. Photo recognition uses a lot of memory, so on devices with limited memory it may be slow or the app may occasionally close.
Your conversations, kept on your device. Meet your own AI friend in ReppoChat.
