Private by design · Fully offline · Android

The only AI app without INTERNET permission on the Play Store.

The app ships without the Android INTERNET permission. Android itself blocks every network connection — Kenosis AI physically cannot phone home. No network, no cloud, no telemetry. It works in airplane mode.

And it still does everything: AI chat, voice-to-voice conversation, video transcription, an eBook reader with read-aloud and audiobook export, and RAG over your own documents — all on-device. Need the live web? An open-source plugin adds web search — the host itself stays offline.

Features

Every feature runs entirely on-device. Live animated demos are right below.

AI chat with suggested follow-ups Add to chat — video, audio, images, e-books, PDF and Office docs
💬

AI chat

Chat with a local LLM that runs entirely on your phone — even in airplane mode. Suggested follow-ups keep the conversation going, nothing you type ever leaves the device, and attached images are analysed on-device by Ask Image.

Live transcription screen Model manager — Gemma, MiniCPM and Whisper downloaded on your terms via Play Store
🎙️

Video transcription

Import any video and transcribe it locally — the transcript streams in live, in 30-second chunks. It runs with the screen off and resumes if interrupted, exports to DOCX or subtitles, and can even dub the video with a new voice. No upload, no server, works offline.

EPUBs, PDFs, DOCX, PPTX, TXT and Markdown — laid out like a book, with text-to-speech read-aloud. Export any of them as a chaptered .m4a audiobook.

RAG — chat with your documents

Ask questions and get answers grounded in your own books and files. Document search runs on the NPU, so retrieval is fast — and fully offline.

Private by architecture

Most apps say "we value your privacy" in tiny grey text. Kenosis AI proves it — in the Android manifest.

No INTERNET permissionAndroid enforces it: the app cannot make a network connection even if it wanted to. A CI gate fails the build if it ever appears.
No storage permissionsFiles are accessed via Android's Storage Access Framework — the app only ever gets a temporary handle to the one file you pick.
No telemetryZero analytics, zero tracking, no accounts. Airplane mode works fine.
Encrypted at restYour library is encrypted on disk — a lost phone doesn't leak your files.
PIN lockAn optional app-entrance PIN with a privacy badge — casual shoulder-surfers see nothing.

FAQ

Does it really work offline?

Yes — completely. The app ships without the Android INTERNET permission, so it cannot connect to anything. Transcription and analysis both run on-device. Airplane mode is fine.

Where do the AI models come from?

Whisper and the LLMs (including Gemma and MiniCPM 5 1B) are downloaded once via Play Store, on your terms, and stored locally. MiniCPM 5 1B is deliberately small — it's the floor model, chosen so that even a 4 GB-RAM phone runs the full chat, voice and RAG stack; bigger devices simply get more headroom.

How can an offline app search the web?

It can't — and that's the point. Web search comes from a separate, open-source plugin app: the host keeps no INTERNET permission, the plugin shows a live log of every request it makes, and you approve each search before it happens.

What devices are supported?

Modern Android phones — and modest ones too: the MiniCPM 5 1B floor model (a 793 MB on-demand pack) brings the whole app to 4 GB-RAM devices. NPU-accelerated embeddings work on Qualcomm, Google Tensor (Pixel) and MediaTek SoCs; other devices fall back to CPU.

Is it free?

Yes — the app is free to download with a 14-day trial of all features. A one-time lifetime purchase is available in the app; no subscription required to keep using it.

How do I report a bug?

Email us — see the "Report a bug" link in the footer. Please include your device model, Android version, and what you were doing when the bug happened.

Why is the transcript better than auto-captions?

It's running on your device — no server round-trip, works on videos that never had captions, and you keep the full transcript in your files library. You can export transcription as subtitles, or even create audio from transcription (per example to replace original voice).

Install it. Turn off the internet. It still works.
