Free AI document reader for Windows, macOS and Linux

Aynaz

Select any words in a research paper or document and Aynaz explains them the way that document uses them, with an example and a diagram; draw a box around a figure and it explains that too. The AI runs on your own computer, so your documents never leave it.

The Aynaz intro: a 3D reader beside a page where the word kernel is highlighted and its explanation has popped out

What it does

A reader for PDF, Word, PowerPoint, Excel, EPUB, ODT, RTF, text and Markdown files, with an explainer built in.

An explanation popup pointing at the selected word in a PDF

Explains words the way this document means them

The same word means different things in different fields. Aynaz reads the sentences around your selection and related passages from the same document, so kernel in a machine-learning paper is explained as a similarity function, not as the core of an operating system. Each answer has the meaning, a real-world example and a small diagram. Deeper asks the model to reason before it answers.

Explains figures, charts and tables

Press Figure and drag a box around a chart, diagram or table. Aynaz says what it shows, how to read it and the takeaway, using the figure's caption and the sentences that mention it. It also works on scanned pages that have no selectable text.

Keeps a history, and works in other apps

Every explanation is kept in a searchable history that you can export as notes. Select text in your browser or any other app and press Ctrl+Shift+E to have it explained there too.

Private

Documents are read and explained on your computer. No account, no upload.

Offline

After a one-time model download, Aynaz works without internet.

Fast on a graphics card

About a second per explanation with a graphics card, about nine seconds on the processor alone.

Free

Free to use for personal, academic and commercial work. Built on open models and tools.

Download and install

Why does my computer warn me? Aynaz is free and made by one developer, so its installers are not signed with a paid certificate. The warning is about the unknown publisher, not about anything in the app. You confirm once; after that Aynaz opens normally.

Windows 10 and 11

Download for Windows about 180 MB
  1. Run the Aynaz-Setup file you downloaded.
  2. Windows shows a blue Windows protected your PC screen. Click More info, then Run anyway.
  3. Follow the installer, then open Aynaz from the Start menu.

macOS Beta

Download for Mac about 200 MB
  1. For Apple Silicon Macs (M1 and later).
  2. Open the .dmg and drag Aynaz into Applications. The window shows the steps below too.
  3. Open Aynaz. macOS says it could not verify Aynaz: click Done.
  4. Open System Settings → Privacy & Security, scroll down and click Open Anyway, then Open Anyway again and enter your Mac password. You do this only once.
  5. To explain text in other apps, allow Aynaz under System Settings → Privacy & Security → Accessibility.
Prefer the Terminal?

After dragging Aynaz into Applications, this one line does the same as the steps above:

xattr -dr com.apple.quarantine /Applications/Aynaz.app

Linux Beta

Download for Linux about 225 MB
  1. For 64-bit Intel and AMD computers.
  2. On Ubuntu 22.04 and later, install FUSE once: sudo apt install libfuse2 (on Ubuntu 24.04: libfuse2t64).
  3. Make the file runnable: right-click it, choose Properties and turn on Allow executing file as program. Or run chmod +x Aynaz-*.AppImage
  4. Double-click it to start Aynaz.

On first start

  • An intro of about 25 seconds shows how Aynaz works each time it starts; then its reader keeps you company beside the welcome screen until you open a document. Click or press Esc to skip the intro.
  • Aynaz offers to download its AI model (2.5 GB) once. It takes a few minutes, resumes if interrupted, and is checked before use.
  • The first time you explain a figure, it offers the figure model (about 3 GB) the same way.

What you need

  • 8 GB of memory (RAM).
  • About 3 GB of disk space, plus 3 GB for figures.
  • A graphics card is optional: NVIDIA, AMD and Intel are used when present.

Mac and Linux versions are marked beta because they have not yet been tested on many machines. If something does not work, please write to the email below.

Updates

When a new version is out, Aynaz shows a bar with a Download button. Install the new version over the old one: your history, settings and downloaded models are kept. Help → Check for Updates Now checks at any time.

Privacy

Your documents and selections stay on your computer. Aynaz uses the internet only to download its models once, and to check this website once a day for a newer version. That check reads one small file and sends nothing about you; turn it off under Help → Check for Updates Automatically. This web page counts visits with GoatCounter, which sets no cookies and keeps no personal data.

Explanations are generated by an AI model and can be wrong. Check anything important against the document itself. Aynaz uses the Qwen3 models (Apache 2.0) and llama.cpp (MIT); their licences are included with the app.
