LingQ vs Octopus Lang: An honest comparison

Before anything else: Octopus wouldn’t exist without LingQ. Steve Kaufmann and his team have been at this for over fifteen years and built the most established input-based learning platform in the world. They proved that learning a language by reading and listening to real content could be a product, not just a method. Every tool in this space, Octopus included, is standing on what they built.

People keep asking how Octopus compares to LingQ. They overlap on a few things and differ on many. Here’s the honest version, including the parts where LingQ is the better tool.

The short version

LingQ is a content library and reading tool that lives on their servers. Monthly subscription, thousands of pre-made lessons in 50+ languages, mobile apps, a built-in review system, and a known-word counter.

Octopus is a desktop app that turns your own films and books into study material. One-time license, your library never leaves your machine, transcription runs locally with Whisper, and vocabulary is tracked by lemma instead of word form. No mobile app yet, no pre-made content library.

That covers the basics. The rest of this post is for anyone still weighing the trade-offs.

Where LingQ is better

Mobile

LingQ has phone and tablet apps. A lot of language study happens on a screen that fits in a pocket. Octopus is desktop only. Mobile is on the roadmap. It’s not here yet.

Content library

When you start a language from zero, LingQ hands you beginner stories with audio, then graded podcasts, then news transcripts. Hundreds of hours of leveled content. Octopus assumes you bring your own films and books.

Built-in review

LingQ has its own SRS with multiple modes. Octopus expects you to use Anki or do without spaced repetition for now.

Tutors

LingQ connects you with paid tutors. Octopus is a solo input tool, full stop.

Known-word counter as motivator

Watching the number climb works for a lot of people. Octopus shows a count too, but we’re more reserved about it.

Where Octopus is better

Lemma-based vocabulary

In LingQ, hablar, hablo, hablas, hablaba, and hablaron are five separate words. They’re all forms of one Spanish verb, to speak. Mark hablar known and the conjugations are still unknown. You mark each form individually.

In Spanish this gets old fast. A regular verb has roughly 50 conjugated forms. In Italian it’s similar. In French, parler gives you parle, parles, parlons, parlez, parlent, parlais, parlait, parlions, parliez, parlaient, parlerai, parleras, and dozens more. Each one shows up as a separate “word” to learn.

The result is that a known-word count for any Romance language in LingQ is inflated by 3–5× and a real share of study time goes to clicking through forms of words you already know.

Octopus tracks lexemes. Mark parler known and the conjugations are known too. When one of those forms shows up in a different book next month, it’s already marked.

Local transcription

LingQ’s content library is broad but finite. If what you want to study isn’t in it, you’re stuck. Importing audio for transcription on LingQ goes through their servers and costs extra.

Octopus runs Whisper on your computer. Drop in a film, walk away for a few minutes, come back to a synced transcript. 22 languages supported today, with dictionary and lemma data for each. More coming. No upload, no per-minute fee, no retention policy. Details on this are in our Whisper post.

Privacy

LingQ uploads what you import. Their servers see what you read, what you save, what you mark as known. Octopus reads your files locally. Your library, vocabulary, and progress stay on your machine. The only thing that ever goes online is a sentence you click translate on, sent directly to the API endpoint you configured.

Pay once

LingQ runs $12–$15 per month. Five years is $720–$900. Octopus is $49.99 once. Software that runs on your computer doesn’t need ongoing server infrastructure, so it shouldn’t need ongoing rent.

Bring your own dictionaries

Octopus reads FreeDict and WikDict. You pick the dictionary that’s actually good for your language pair, instead of getting whatever the platform decided to bundle.

Reading interface

LingQ is a web app. The reader is serviceable but it shows: sidebars, chunks of lesson content, the occasional loading state, a session that can time out. You’re reading inside a SaaS product.

Octopus is a native desktop app. The reader is a clean two-page spread that fills your window like a real book — no browser chrome, no marketing, no network round-trip when you click a word. Dictionary lookups are instant because everything runs locally. Pages turn with the keyboard. The book stays open as long as your laptop is open. You can read offline on a plane.

If you read for hours at a time — which is the only way input-based learning actually works — these differences compound. After an hour in LingQ, you’re still aware you’re in a web app. After an hour in Octopus, you’re just reading.

Roughly even

Anki export

Both export to Anki. Octopus’s cards include the audio clip from the moment you saved the word. LingQ’s are simpler. If you sentence-mine seriously, the Octopus cards are better. If you drill words, both work.

Click-to-define while reading

Both do it. The interaction is fine in both.

Who picks which

Pick LingQ if: you’re starting a language from scratch with no media you love in it; you study primarily on your phone; you want tutors built in; you don’t use Anki and don’t want to.

Pick Octopus if: you already have films and books to study from; you’re studying a Romance language and tired of marking every conjugation; you want your library to stay on your machine; you don’t want to pay monthly forever; you already use Anki and want better cards; you study primarily at a desktop.

Pick both if: you want LingQ’s content library to bootstrap a new language and Octopus once you graduate to native media.
