Free on desktop, Android and web; the iOS app is a one-off paid purchase that funds the project. The interface is dated and the options are overwhelming at first, but nothing beats it for retaining vocabulary over years. Most effective when you stop grinding premade decks and start mining sentences from things you actually read or watch.

A free public search service listing Finnish courses in Helsinki, Espoo, Vantaa and Kauniainen by level, schedule and starting point, including the many cheap or free options run by adult education centres, and including online courses open to anyone. If you live in Finland, this is how you find an actual class instead of guessing. It covers only the capital region physically, and it lists courses, not their quality.

Foreign Service Institute, Peace Corps and DLI materials — full textbooks plus hundreds of hours of audio — are public domain and hosted here for free across dozens of languages. The depth is extraordinary and the FSI Basic courses take diplomats to professional working proficiency, which no consumer app attempts. The recordings are from the 1960s–80s, the drills are relentless, and some vocabulary is dated (Cold War era), so they suit disciplined self-studiers, not casual learners.

Developed with support from Finland's Ministry of Education and Culture, Kielibuusti gathers free study paths, work-life vocabulary, speaking practice material and guidance for learners, teachers and employers in one place, in Finnish, Swedish and English. It is aimed squarely at adults who moved to Finland for work and need usable language fast. It is a hub, so quality varies by linked resource, and much of the site assumes you are living in Finland.

Short, practical rulings on spelling, punctuation, compound words, name inflection and the hundred small usage questions that come up once you start writing Finnish seriously. It is the resource Finnish editors and journalists actually check. Entirely in Finnish and normative in tone, so it is for writing accuracy rather than learning to speak.

Published by the Institute for the Languages of Finland, this is the authority on what a Finnish word means and how it inflects, with the inflection-class number on every headword — which is exactly the information you need to decline anything correctly. Switching to it from bilingual dictionaries is a milestone worth aiming for. Finnish-only definitions make it impractical much below B1.

Thousands of public-domain books recorded by volunteers, downloadable as MP3 or M4B with no account. Pairing a LibriVox recording with the matching free Project Gutenberg text gives you a full audiobook-plus-ebook study set for nothing. Two caveats: recordings are volunteer-quality and vary a lot reader to reader, and everything is out of copyright, so the language is often a century old — great for literature, poor for modern slang.

The default place to ask 'is X app worth it' or 'what should I do at B1' and get answers from people who have actually done it, plus per-language subreddits (r/Spanish, r/LearnJapanese, r/French) with far better resource lists. The wiki and FAQ head off most beginner questions. Expect strong ideological camps — comprehensible-input purists versus textbook people — so read a few threads before taking any single answer as settled.

Native speakers answer grammar and usage questions here, and the subreddit wiki holds one of the most complete resource lists for Finnish anywhere, covering dictionaries, courses, textbooks and university course listings. Useful both for asking and for browsing. Parts of the wiki have not been updated in years, so check that a linked site is still alive before relying on it.

Details
A private Finnish teacher who has been writing about the language for over a decade, mixing grammar explanations, easy-Finnish reading, book recommendations and a podcast with well over a hundred episodes; both blog and podcast are still active in 2026. Her specialism is easy Finnish, so the material lands well for learners stuck between beginner courses and native content. The blog is unstructured by design — it is a stream of lessons, not a syllabus.

A collaborative, Creative Commons-licensed corpus you can search for real usage of a word or download in bulk to build your own decks. It is the raw material behind Clozemaster and countless Anki decks rather than a study tool in itself. Sentences are contributed by volunteers, so quality and naturalness vary — prefer sentences from native contributors and cross-check anything surprising.

Inge's site is the reference English speakers actually use for Finnish grammar: consonant gradation, all six verb types, the case system and endless vocabulary lists, each explained patiently with examples. The interactive exercises that used to sit behind a points system are now free for everyone. It is a reference rather than a curriculum, so you need a course or teacher to tell you what order to learn things in.

The full text of Iso suomen kielioppi, the 2004 reference grammar of Finnish, with its terminology definitions and search tools, made freely available online by the Institute for the Languages of Finland. When no learner resource can settle a question about Finnish syntax, the answer is in here. It is written in Finnish for linguists and is genuinely difficult — a last-resort reference, not study material.

vocabularygrammarpronunciation
Details
Over 100 language editions; the English edition alone has millions of entries covering hundreds of languages, with IPA, declension and conjugation tables, etymologies and usage notes that commercial apps usually paywall. The etymology sections are quietly one of the best vocabulary-retention tools available. Being crowd-sourced, coverage is uneven and rare entries can be wrong — cross-check anything unusual against a native-language dictionary.

The full Yle catalogue — drama, documentaries, children's programming, radio and hundreds of podcasts — much of it subtitled in Finnish, which is the most effective bridge into spoken Finnish once you have basic grammar. Children's series and the selkosuomi content make usable entry points at B1. A large part of the video catalogue is geo-blocked outside Finland, though much of the audio is not.

Modern assistants (ChatGPT, Claude, Gemini) will roleplay a scenario at your level, correct your writing with explanations, generate graded reading, and hold voice conversations — endlessly patient and available at 2am, which no tutor is. Free tiers are enough for text practice; voice modes generally need a subscription. The caveats are real: models are noticeably weaker and more error-prone in lower-resource languages, they tend to produce bland textbook register rather than how people actually speak, and they will not correct you unless you explicitly ask them to.

Details
Built on Tatoeba sentences, it drills words in context by frequency band across 50+ languages and 170+ language pairings, with a genuinely generous free tier. It explicitly starts where beginner apps end, so it is the natural 'what now?' answer for someone who finished a Duolingo tree. Sentences are crowd-sourced and occasionally awkward or oddly specific, and it teaches nothing about grammar explicitly.

A franchise of local producers filming unscripted street interviews, each episode subtitled in the target language and English, which is the closest free thing to hearing how people genuinely speak. All YouTube episodes are free; membership adds transcripts, vocabulary lists and exercises. Real-speed unscripted speech is hard early on — start with the slower 'Super Easy' episodes if you are below B1.

Around 6 million words recorded by native speakers across 400+ languages, usually with several accents per word so you can hear regional variation. Free to search on the site; the paid tiers are aimed at API users and bulk audio downloads. Indispensable for names, place names and anything a TTS voice would mangle — many learners wire it directly into Anki for card audio.

Details
Built-in correction tools let partners fix your messages inline, and the social 'moments' feed gets you corrections from strangers without arranging a call. Free for the core exchange; VIP adds more translations and simultaneous target languages. The persistent caveat is that a fair share of users treat it as a dating app, and exchange partners are unreliable — it works best once you already have some output to correct.
Dual subtitles and click-to-look-up on Netflix and YouTube.

Details
A Chrome extension that shows target-language and native subtitles simultaneously, lets you click any word for a definition, replay a line, and save phrases for review. The free tier already covers dual subs, dictionary lookups and the CEFR-graded video catalogue; Pro (about $6/month) adds machine translation, speech recognition and better AI lookups. It transforms passive Netflix time into study time, but you need enough of a base — roughly B1 — for subtitle mining to beat just watching.

Import podcasts, articles or ebooks, tap unknown words for definitions, and LingQ tracks your known-word count over time. The free tier caps how many saved words you can keep, so serious use means paying (~$13/month or less annually). The interface is clunky and the built-in SRS is weaker than Anki, but the reading-plus-audio workflow with 50+ languages is hard to replicate elsewhere.

A browser extension plus web reader covering 100+ languages: click a word or drag across a phrase, get an inline translation, and it becomes a flashcard automatically. The free tier gives unlimited single-word translations but caps phrases and AI explanations at 10 a day; Premium is $6/month. Simpler and cheaper than LingQ or Migaku if all you want is frictionless reading of articles and ebooks.

A detailed staged roadmap for acquiring a language through massive comprehensible input — what to do at each stage, when to start output, how to mine sentences — with a free tracker, starter courses and an active Discord. The roadmap and community are free; vocabulary decks, advanced courses and coaching are paid. It is opinionated to the point of dogma about avoiding early output and translation, so take the framework and ignore the purity rules if they do not fit your goals.

Same idea as HelloTalk but with vetted profiles and a cleaner focus on actual voice and video calls, which makes it noticeably less spammy in practice. Free to use; Pro adds unlimited partner search and extra languages, and the app also sells paid tutors. Both apps live or die on finding one or two committed partners, so expect to message a lot of people before anything sticks.

Karlsson, a Helsinki linguist, lays out Finnish phonology, the case and verb systems and sentence structure in English, systematically and with enough examples to actually use. It is the book to reach for when a website explanation leaves you unsure. A reference work with no audio and few exercises — it explains Finnish, it does not teach you to speak it.

One-on-one video lessons from roughly $5–30/hr depending on the language and the teacher's credentials. It is the single fastest way to get real speaking practice, and the reason most self-study plans stall is that they skip this step. Community tutors are cheap conversation partners; professional teachers are worth it if you want structure, homework and error correction.

A streaming service where every show has clickable dual subtitles and saved words become flashcards, covering 15 languages with apps on phone, Roku and TV. It solves the 'what do I watch' problem for languages where Netflix's catalogue is thin. The library is much smaller than a mainstream streamer and it is subscription-only — if you already pay for Netflix, Language Reactor's free tier does most of the same job.

A 10-day free trial then a subscription (roughly $10/month). Overkill unless you are committed to a sentence-mining routine — if that describes you it saves hours a week, otherwise Language Reactor's free tier is enough.

speakinglisteninggrammar
Details
100,000+ tutors across 120+ subjects, with a free replacement if your first tutor is a bad fit. The main structural difference from italki is that Preply pushes weekly lesson subscriptions and takes a large commission from tutors, which some learners consider a reason to prefer italki. Worth comparing side by side for your language — prices, availability and tutor quality differ per market rather than per platform.
