KernelAI - Offline AI Chat

About this app

ON-DEVICE AI Downloaded compatible models run locally on your device. KernelAI checks model compatibility and memory needs before you download, so you can choose a model that fits your iPhone or iPad. CHAT WITH DOCUMENTS Ask questions about PDFs, DOCX, CSV, Markdown, and text files. Summarize, search, and find useful passages with on-device document chat. UNDERSTAND IMAGES Attach a photo, screenshot, chart, or diagram and ask what it shows with a compatible vision model. Image analysis runs on-device. 50+ MODEL OPTIONS Choose from 50+ models, including Llama, Gemma, Qwen, DeepSeek, Mistral, Phi, and more. Import compatible GGUF models from Files, URLs, or your local network. WRITE, LEARN, AND CODE Use local models for writing, brainstorming, explanations, and code. Generate, explain, and review code with models selected for programming. CUSTOMIZE YOUR AI Set a system prompt and generation parameters for each model. See tokens-per-second, context usage, and generated thinking output from supported reasoning models. VOICE, SIRI, AND SHORTCUTS Dictate prompts with voice input. Ask KernelAI from Siri or build it into Shortcuts on supported iOS versions. On supported iOS 26 devices, Apple's built-in on-device model can answer in the background; downloaded models may open KernelAI while they run. ORGANIZE YOUR WORK Keep conversations in folders, search your history, branch a chat, edit or regenerate messages, and export your work. Use KernelAI on iPhone and iPad, including from the Share Sheet and Home Screen widget. OPTIONAL WEB SEARCH Turn on web search when you need current information. Add your own Tavily or Exa API key; web search is off by default. Provider fees may apply. Everything currently available is free. There is no Pro tier or subscription.

KernelAI 2.0 is the biggest update we have ever shipped, and it did not come from a roadmap, it came from you. Every piece of feedback, every feature request, every "please just add this" got read, and this release is the answer. We rebuilt the app to feel native from the ground up: a new navigation drawer, smoother streaming, cleaner chat, and dozens of fixes you will feel the moment you open it, even before you notice a single new feature. What is actually new: • Chat with PDFs, DOCX, CSVs, Markdown, and text files on-device • Ask questions about photos, screenshots, charts, and diagrams with vision models • Choose from 50+ device-matched models, including Qwen 3.5 and Gemma 4 • View generated thinking output from supported reasoning models • Dictate prompts with voice input • Organize work with folders, search, branching, custom prompts, and export • Ask KernelAI from Siri and Shortcuts on supported iOS 26 devices • Reliability, performance, and accessibility improvements throughout Download a model once, then test local chat in Airplane Mode. No account or subscription required.

Momentum comes from crawler snapshots for the tracked storefront. “Viral growth signal” means unusually fast recent rating gains; it is an indicator, not download data.
