Readlang vs LingQ: which one fits how you actually read

Readlang and LingQ agree on the important thing: you get a language by reading real content in it and dealing with the words you don't know, one at a time. Everything below is a disagreement about packaging.

If you're choosing between them, the decision comes down to a single question — do you need the content brought to you, or do you already have things you want to read?

Side by side

	Readlang	LingQ
What you read	Anything you paste or open in the browser reader	A large built-in library (thousands of lessons with audio) plus imports
Click-a-word	Fast, minimal, translation popup	Fast, plus a known/unknown state tracked across everything
Reviews	Basic flashcards	Interval-based review of your saved LingQs
Progress stats	Light	Its best feature — known-word counts that genuinely pull you forward
Mobile	Weak	Real iOS and Android apps, with moods
Interface	Sparse, a little dated	Busy — a lot of surface area
Price shape	Free tier, cheap paid tier	Subscription only, streaming-service money
Momentum	Slow development	Actively developed

Choose Readlang if

You already know what you want to read. You have articles, fanfiction, a novel you've been meaning to attempt, and you want a thin layer that turns clicking into flashcards without asking you to move into a platform. It's cheap, it doesn't nag, and the free tier is real (until you hit the phrase-translation cap).

The honest downside: it feels like a tool from an earlier internet, and updates arrive slowly.

Choose LingQ if

You open a reading app and think "…now what?" The library solves the blank-page problem, the audio makes it usable on a commute, and the known-word counter is the most effective motivation device anyone in this space has built. If you're mid-level in a big language and just need volume, LingQ delivers volume.

The honest downside: it's the priciest option in the category, the interface asks a lot of you, and importing your own content is fussier than it should be.

The case where neither wins

Both tools assume reading is a destination — you go to their site, in their reader, during study time.

For a lot of people that's just not where the reading happens. The Spanish news you actually open is in a tab. The Japanese blog post came from a link someone sent you. Study time never arrives, but tabs keep arriving.

Mossglen (full disclosure: ours) is built for that shape. It's a free Chrome extension — the page you already opened becomes a clean reading view in place, no importing. Tap a word for the meaning and it's saved with its sentence; a short quiz after reading keeps the next text calibrated to your level; reviews run on FSRS, a newer spaced-repetition scheduler than the interval systems both tools above use. Works without an account, in 8 languages (EN, ES, FR, DE, IT, PT, JA, KO), and it handles YouTube videos the same way.

What it doesn't have: a curated library, audio lessons, or a mobile app. The internet is the library, and the browser is the app.

Deciding in one line

• You have content, want it cheap → Readlang
• You need content handed to you, will pay for it → LingQ
• Your reading already happens on the open web → a browser extension beats both

And if you're mid-switch, don't rebuild everything at once. Run one tool for two weeks of normal reading and keep whichever made you read more.
