Probably not the coolest app here, but I built a 5MB native Mac dictionary with open formats and AI you control.

Hey r/macapps,

Problem: A quiet place to look up words and really understand them.

I wanted a small, native dictionary app (also universal) where I could look up a word, take my time with its meanings and examples, and compare explanations across dictionaries. No distracting services or another subscription. Just a quiet place to understand what I’m reading.

So I built Open Dict. The Mac app is about 5.2 MB before adding dictionaries, no signup.

A few things, done well:

Bring your dictionaries: import MDX/MDD, MOBI, StarDict, dictd, TXT and TSV. Use your existing collection or explore free and open-source dictionaries. Local lookups work offline.
Search your whole library: one query across your dictionaries, with easy switching to compare definitions.
Choose your own AI: bring your API key for OpenAI, Claude, Gemini, DeepSeek, Kimi or GLM, or connect a custom API. Auto-load the available fast models, choose your preferred one, and customize the explanations. AI is entirely optional.
Keep what you learn: save words, highlight sentences, and add notes. Sync through your own iCloud across Mac, iPhone and iPad (iPhone/iPad coming soon). No separate account or app subscription needed.

Two built-in AI prompts cover concise definitions and detailed learner explanations. Your own prompt can be as simple as:

>Explain {word} briefly in English, Japanese and Spanish, with two example sentences in each language.

The app fills in the word. You can edit and test your prompts whenever you like.

Comparison

Apple Dictionary is handy for quick, built-in lookups. Open Dict focuses on building your own library from common dictionary formats, searching across those sources, and adding AI explanations with models and prompts you control.

If you collect dictionaries or learn in several languages, that flexibility is the main reason to try it.

Pricing

The free version supports up to 5 dictionaries, with no other feature restrictions or time limit. A US$9.99 one-time purchase permanently removes the dictionary limit. No app subscription.

Open Dict is a Universal App: one purchase covers Mac, iPhone and iPad with the same Apple Account. Mac is available now; iPhone and iPad versions are in App Store review.

What do you use for dictionary lookups on your Mac? I’d love to hear what’s missing from your current setup.

I need an app that allows me to quickly save and organize all the links of my Safary tabs

I'm one of those people who never closes his Safari tabs. From time to time I make a quick look up and close those that are redundant or not important, but the hundreds of somewhat relevant apps are still there.

One of the solutions is, usually, to open the left bar, right click on the top of the tab group, copy all links, then paste the links into a text note.

But I'm quite sure there has to be a better way of not only saving hundreds of tab links, but also to organize them and be able to search among them once saved.

Have you stumbled upon (pun intended) any app or service specialized at this?

Recommendation for Menu bar apps hider

Hi Guys

I have a question about which app successfully hides menu bar apps on Golden Gate. I have tested several options, and they do not function there, though they worked well in earlier macOS versions.

Are there any recommendations from people who have tried and tested this?
