Jan.ai Alternative for Mac: Lekh AI Private Local App (2026)

The best Jan.ai alternative for Mac is Lekh AI, a private app that runs MLX and GGUF models on Apple Silicon and adds document search, voice, and image tools. Jan is a solid free app for chatting with local models. But many Mac users want more from the same machine. They want models built for Apple chips, answers from their own files, and tools that go past chat. This post shows what Lekh AI offers, what to check before you switch, and which version fits your Mac.

Why People Look for a Jan.ai Alternative on Mac

People look for a Jan.ai alternative on Mac when they want more than a chat window. Jan is free, open source, and able to connect to online models, and that suits many users well. The gaps show up when you use it for more than chat. If your work involves private files, that split matters. You would run chat in one app and look elsewhere for the rest.

Jan's docs mark its MLX engine as experimental. On MLX, embeddings are unavailable, so document search needs the llama.cpp engine instead. The docs also say some newer model designs fail to load on MLX. That matters on a Mac, because MLX is the framework Apple built for its own chips.

Jan's documentation centers on chat, assistants, projects, and model connections. If you also want to turn text into speech, create images, or search a private library of files, you need other tools. Some local AI apps for Mac stop at chat, so it helps to know what else you need before you pick one.

What to Look for in a Jan.ai Alternative on Mac

A good Jan.ai alternative for Mac keeps your data on your device and makes full use of your Apple chip. Use this checklist, and see how Lekh AI answers each point.

1. Local processing: Privacy-first AI tools keep chats, files, and images on your device. Lekh AI's privacy page says no internet connection is needed to chat, generate images, or use text-to-speech. It also says the app collects zero telemetry.

2. Apple Silicon support: Lekh AI is built for M-series Macs and supports MLX, Apple's own machine learning framework.

3. Model formats: It runs MLX, GGUF, and JANG models, with more than 1,000 models available.

4. Document search: Its Knowledge Hub lets you save documents and ask questions about them.

5. Voice: Kokoro and Qwen3 TTS read text aloud, and Pro adds WhisperKit for speech-to-text.

6. Creative tools: You can generate and edit images on your Mac. Pro adds Flux models and ACE-Step music.

7. Price: The Mac App Store version costs $4.99 with a 3-day free trial. Pro is a $29.99 one-time purchase.

Lekh AI as a Jan.ai Alternative for Mac

Lekh AI is a native Mac and iPhone app from Kaila Labs that runs AI models on your device with no account or API key. It is one app for local chat, document search, voice, and image tools.

The Lekh AI for Mac app is tuned for M-series chips. The 8 GB minimum makes it usable on entry-level Macs, though larger models need more memory. It supports several model families, including Llama, Qwen, Gemma, Mistral, Phi, and DeepSeek. You can use it as a local AI assistant for Mac for writing, questions, and research.

Lekh AI Pro can also connect to online AI services if you choose to add them. Models you run locally stay on your Mac.

What You Can Do in Lekh AI Beyond Chat

Lekh AI lets you chat, search your files, hear text read aloud, and create images in one Mac app. Each tool runs on your device.

Ask questions about your own files: Knowledge Hub stores your documents, PDFs, and notes. It uses local retrieval, called RAG, to find the right passages and answer with context from your files.

Hear text read aloud: Lekh AI reads text with Kokoro and Qwen3 TTS voices. You can import ePub books, turn them into audiobooks, and export the audio.

Create and edit images: The app makes images with Stable Diffusion and SDXL models. It also includes 4x upscaling and an object remover, and it lists LoRA support for custom image styles. These offline AI tools sit in one app, so you do not need to switch between several.

Go further with Pro. Lekh AI Pro adds Flux image models, ACE-Step music, WhisperKit speech-to-text, a model converter, and benchmarking.

MLX, GGUF and JANG Models on Apple Silicon

Lekh AI runs MLX and GGUF models, plus JANG models, on Apple Silicon. Each format fits a different need.

MLX is Apple's machine learning framework, and its models are built for the unified memory in M-series chips. GGUF is the format used by llama.cpp, and it opens thousands of community models on Hugging Face. JANG is an adaptive format for MLX models. It assigns different bit widths to different layers instead of one width for the whole model.

MLX is built for Mac, while GGUF is built to run almost anywhere, so the MLX vs GGUF choice depends on your goal. Lekh AI lists model sizes from 0.5B to 397B. Pro also includes a converter that turns Hugging Face models into MLX, GGUF, or JANG.

Which Lekh AI Version Fits Your Mac

Pick the Mac App Store version to try Lekh AI, and pick Pro if you want Flux, transcription, and the model converter.

The Mac App Store version costs $4.99 and includes a 3-day free trial. It is the easiest way to test Lekh AI on your Mac. Pro costs $29.99 as a one-time purchase, with no subscription. You download it directly, then enter your email and license key. Because it is not sold through the App Store, Pro avoids App Store sandbox limits.

Flux image models are Pro only. Both versions need macOS 15 or later and an Apple Silicon chip. Pro is Mac only, and the iPhone app is sold separately.

How to Switch From Jan.ai to Lekh AI

You can switch to Lekh AI in four short steps.

1. Check your Mac: You need Apple Silicon, macOS 15 or later, and at least 8 GB of RAM. 16 GB is recommended.

2. Install the app: Start the 3-day free trial.

3. Pick a model size: Smaller models suit 8 GB Macs, and larger ones need more memory. The best local AI model for Mac depends on your RAM.

4. Add your files: Put documents in Knowledge Hub and start asking questions.

Lekh AI also offers AI on iPhone through a separate app.
