Ensu actually runs AI on your phone — no cloud, no cost
Ente just launched Ensu, a free open-source AI chat app that runs entirely on your device. No accounts, no tracking, no internet required — available on iOS, Android, Mac, and Linux.
The team behind Ente — the privacy-focused photo storage app trusted by thousands — just released something unexpected: a full AI chat app that never sends a single byte to the cloud.
Ensu is a ChatGPT-style assistant that runs 100% on your device. No account needed. No subscription. No usage limits. It works offline on a plane, in a cabin, or anywhere without internet. Your conversations never leave your phone or laptop.
Why This Matters Right Now
Every major AI assistant — ChatGPT, Gemini, Claude — sends your messages to remote servers. That means your personal thoughts, business ideas, health questions, and private writing all live on someone else's computer. Ensu flips that model entirely.
The app runs a small but capable AI model (LFM 2.5 VL with 1.6 billion parameters) directly on your device's processor. On Macs with more memory, it can use Gemma 3 4B for better responses. It even understands images — you can attach a photo and ask questions about it.
What Ensu can do today
- Chat offline — works without internet, perfect for flights and remote areas
- Analyze images — attach photos and ask questions about what's in them
- Write and brainstorm — draft emails, journal entries, or ideas privately
- Multi-language support — responds in multiple languages
- Cross-platform — available on iOS, Android, macOS, Linux, and Windows
The Honest Trade-Off
Ensu isn't as powerful as ChatGPT or Claude. The AI model is small enough to fit on a phone, which means it's limited to 4,096 tokens of context (roughly 3,000 words of conversation) and 512 tokens of output per response. Some users on the Privacy Guides community reported occasional repetitive or cut-off responses.
Ente themselves call this "just a checkpoint" — they know it's early. But the core promise is real: a free AI that works without internet and keeps everything on your device.
Coming Soon: Encrypted Sync Across Devices
The next major feature will let you connect an Ente account (or self-host your own server) to back up and sync your conversations across devices — all with end-to-end encryption. That means even Ente can't read your chats.
The team is also exploring a unique direction: instead of just a chatbot, Ensu could become "a single, never-ending note where the AI offers suggestions, critiques, reminders, and alternative viewpoints" — more like an AI thinking partner than a question-answer machine.
Try It Now
Ensu is free and open source. Download it from:
- App Store (iOS, Mac with Apple Silicon)
- Google Play (Android)
- GitHub (Linux, Windows, source code)
The app is 32 MB to download, but the AI model itself adds 600 MB to 3 GB depending on your device. First launch takes a few minutes while the model downloads.
