The gold-standard spaced-repetition flashcard app with community decks for every language.
AppsTools Free BeginnerIntermediateAdvanced
vocabulary
Details
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.
Free open-source Cantonese-English dictionary, searchable by jyutping or Yale.
DictionariesTools Free BeginnerIntermediateAdvanced
vocabularyreading
Details
Pleco's open Cantonese project: it merges the CC-Canto database with CC-CEDICT and Cantonese readings, so you can search by characters, jyutping, Yale or English and get clean English definitions. Everything is free, the data is downloadable, and the same dictionary installs as a free add-on inside the Pleco app for offline lookup on a phone — the usual setup for serious learners. It leans on Mandarin-era CC-CEDICT data for many entries, so for colloquial Cantonese usage check words.hk as well.
A teacher and a student in real Cantonese conversation, with transcripts.
Podcasts Free IntermediateAdvanced B1–C1
listeningvocabularyimmersion
Details
Forty-plus episodes of unscripted Cantonese conversation aimed at building listening, interleaved with English-language interviews with people in the global Cantonese world — linguists, literary translators, community-school teachers — and every episode links a transcript and vocabulary list. The transcripts are what make the Cantonese episodes usable at intermediate level. It stopped publishing in April 2025, so this is a complete free archive rather than a live show.
Free public-domain US government language courses with textbooks and audio.
CoursesBooks Free BeginnerIntermediateAdvanced A1–C1
grammarlisteningspeakingreading
Details
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.
Comprehensible input in Cantonese only, colour-coded from zero to advanced.
YouTubePodcasts Free BeginnerIntermediateAdvanced A1–B2
listeningvocabularyimmersion
Details
Built explicitly on Krashen and the ALG approach: every video is in Cantonese with visuals and context doing the explaining, and each title is tagged complete beginner, beginner, intermediate or advanced so you can find your level immediately. Topics come from Hong Kong life and news, uploads ran several times a week through August 2026, and there is an audio-only podcast version. It is free. The channel is young, so the higher levels have less material than the beginner tiers, and there is no grammar explanation anywhere by design.
Free public-domain audiobooks in 40+ languages, read by volunteers.
Media Free Advanced B2–C2
listeningimmersion
Details
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 main English-language forum for Cantonese learners and native speakers.
Communities Free BeginnerIntermediateAdvanced
vocabularyreadingwriting
Details
The place to ask what a phrase means, get a sanity check on a translation, or find out which resource people actually use, with native speakers and long-term learners answering — plus recurring debates about romanisation, written Cantonese and the language's political situation that are worth reading once. Free and searchable, so check the archive before posting. Answers are crowd-sourced and occasionally confidently wrong, and threads skew toward Hong Kong usage.
3M-member forum for method debates, resource recommendations and reality checks.
Communities Free BeginnerIntermediateAdvanced

Details
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.
Hong Kong's public broadcaster: live Cantonese radio and on-demand archives.
Media Free Advanced B2–C2
listeningimmersionvocabulary
Details
Radio 1 and Radio 2 stream live and almost everything is available on demand, giving you unlimited free Cantonese news, phone-ins, drama and culture programming recorded for Hong Kong people rather than for learners. It is the most reliable free source of native Cantonese audio outside Hong Kong, since the commercial streamers geo-block. Nothing is graded or transcribed and the site is clunky to browse, so save individual programmes you like rather than trying to navigate it each time.
Open database of 13M example sentences with translations across 400+ languages.

readingvocabularygrammar
Details
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.
Free multilingual dictionary with etymologies, IPA and full conjugation tables.
DictionariesWebsites Free BeginnerIntermediateAdvanced
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 modern Cantonese dictionary, defined in Cantonese by Cantonese speakers.
Dictionaries Free IntermediateAdvanced
vocabularyreading
Details
A large crowd-built dictionary where entries are defined in Cantonese itself with jyutping, usage examples and English glosses on many words, alongside a corpus of written Cantonese text. Because it documents how people actually speak, it catches slang, particles and internet coinages that older Chinese dictionaries pretend do not exist. The main site is in Chinese; CantoWords.com is the same data with an English interface, which is what most learners should use. Not every entry has an English gloss yet.

Type a word or phrase and it plays back real YouTube clips of people saying it in context, across 25 languages plus sign languages, so you get natural intonation and regional variation rather than an isolated dictionary recording. Free, donation-supported, no account needed. Complements Forvo: Forvo for single words, YouGlish for phrases and prosody.

speakingwritinggrammarvocabulary
Details
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.
Fill-in-the-blank sentence drills for vocabulary after you know the basics.

vocabularyreadinggrammar
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.
Street interviews with dual subtitles, produced in dozens of languages.

listeningimmersionvocabulary
Details
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.
Crowd-sourced pronunciations of nearly any word by native speakers.

pronunciationlistening
Details
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.
Text, call and correct with native speakers in a language-exchange feed.
AppsCommunities Freemium BeginnerIntermediateAdvanced
writingspeakinglistening
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.
Tools Freemium IntermediateAdvanced
listeningreadingvocabularyimmersion
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.
Read and listen to real content while tracking every word you know.

readinglisteningvocabularyimmersion
Details
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.
Click any word while reading the web to translate it and make a flashcard.

Details
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.
Free immersion-learning roadmap plus tools and a large learner community.

immersionlisteningreadingvocabulary
Details
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.
Language-exchange app with moderated profiles and easy voice/video calls.

speakingwritinglistening
Details
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.
Matthews and Yip's standard reference — the serious book on Cantonese grammar.
Books Paid IntermediateAdvanced B1–C2
grammarreadingwriting
Details
The reference work for the language, describing spoken Hong Kong Cantonese systematically: classifiers, aspect markers, the sentence-final particles that carry so much of the meaning, comparative and relative structures, and code-mixing with English, all with jyutping and translations. If you have ever wondered why a particle changes the whole tone of a sentence, the answer is in here. It is a linguist's description with no exercises and no audio, and it costs reference-book money — buy it when courses stop answering your questions.

Details
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.
Licensed TV shows with interactive subtitles in 15 languages.

Details
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.

The heavyweight immersion toolkit: one-click sentence mining with audio, screenshot and definitions, plus its own SRS and known-word tracking, for 11 languages including Japanese, Korean, Mandarin and the major European ones. 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.
Large tutor marketplace with subscription-style lesson packages.
Tutoring Paid BeginnerIntermediateAdvanced
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.
