Offline AI that runs on your phone.
Chat, write, reply, translate, and edit with an on-device AI engine built for Android. Krexel keeps models on your phone, supports offline use, and gives you direct control over how your AI behaves.
One Android app, built around the ways people actually write and reply.
Krexel is not just a chat screen. It is a private on-device toolkit for communication, writing, and translation across everyday Android workflows.
Chat AI
Persistent session-based conversations for questions, drafting, planning, and day-to-day help without pushing the core experience into the cloud.
Keyboard AI
Use AI inside the keyboard to write faster, fix phrasing, summarize long text, and generate replies where you are already typing.
Note AI
Rewrite, improve grammar, summarize, translate, or run custom instructions on notes and drafts directly inside the app.
Translation
Translate text in-app without turning your private writing flow into a browser tab or external cloud tool.
Notification Reply Assistance
Generate and shape replies for messages and notifications across multiple supported Android apps, not just a single messenger.
On-device Model Management
Download curated GGUF models, import local files, search Hugging Face flows in-app, and offload models when you need storage back.
Your AI stays closer to you.
Krexel is built around local inference on Android. Once the model is on your phone, the core AI experience is designed to keep processing on-device so your writing, replies, and edits stay under your control.
- Built for offline use after models are downloaded or imported.
- Users control which GGUF model is loaded, offloaded, or swapped.
- Focused on Android, local inference, and direct user control over the AI stack.
Safer AI modes built into the product.
Krexel includes Child Safe Mode, Adult Mode, and built-in content filtering across chat, keyboard assistance, notes, and reply suggestions.
- Child Safe Mode for more restrictive outputs.
- Adult Mode when broader responses are appropriate.
- Filtering works across the app instead of living in a single screen.
Replies that match how you actually communicate.
Shape results with profile context, tone, formality, emoji preference, greeting style, sign-off style, family and friend context, and quick facts that influence how Krexel writes for you.
Bring your own model, or download one in-app.
Krexel includes curated downloadable GGUF models and a local import path, with in-app discovery flows designed around mobile-friendly options instead of oversized promises.
Curated starters
Examples include Gemma-3 1B, TinyLlama, Qwen 0.5B and 0.6B, MobileLLaMA, and OpenELM.
Hugging Face flow
The app includes model search and detail flows so users can explore supported options before importing.
Phone-aware management
Load what you need, keep multiple models available, and offload when storage or memory matters.
Useful on the phone you already carry.
Krexel is designed for quick writing help, better replies, private translation, and a personal AI layer that stays close to your Android workflow.
Reply faster across apps
Generate polished responses from incoming notifications and messages without bouncing between tools.
Rewrite notes and messages
Clean up grammar, shorten long drafts, or change tone before you send or save anything.
Translate on-device
Translate text directly in the app as part of the same writing flow.
Keep AI inside the keyboard
Get help where you type most, instead of copying text into a separate service.
