Corodomo vs Miraa: a guided video library or AI subtitles for your own media?

By Official AppDuo editorial team · Updated

Quick verdict

Both teach languages through subtitled videos and podcasts with shadowing practice, but they start from different places.

Corodomo: a curated library by topic and level, word-level AI pronunciation scoring, 1:1 AI shadowing coaching, CoroAI conversation practice and exam prep, on web, iOS and Android. The trade-offs are higher prices and an AI-hour allowance shared between subtitle generation and speaking practice.

Miraa: turns YouTube and podcast links you choose into bilingual subtitles with AI word and grammar explanations, at a low price (Basic $0.99/month on the US App Store). The trade-offs are mobile-only apps, no described pronunciation scoring, a thin privacy policy and a no-refund rule.

Head-to-head

Corodomo leads on 6, Miraa on 3, 1 even

FeatureCorodomoMiraa
Where the material comes from[1],[14],[3],[17],[15],[20]A curated library by topic and level (everyday life, business, IT, news, plus an IT Passport course), which the Corodomo team says is reviewed. You can also add your own videos, including from YouTube.Mostly material you pick: paste a YouTube or podcast link, or choose a built-in podcast, and AI transcribes it into bilingual subtitles. A WaniKani forum user reported subtitles arriving in about a minute.
→ Learners who want material chosen for their level fit Corodomo; those who already know which channels and podcasts they want fit Miraa. Neither app's AI subtitles for imported media have been independently tested for accuracy.
Allowance for transcribing your own media[2],[3],[19],[15]Subtitle generation uses AI hours shared with detailed pronunciation scoring and speaking. Free: 1 hour/month and up to 3 imports; Plus: 30 hours/month, videos up to 2 hours; Pro: 100 hours/month, videos up to 4 hours, bulk import.Free: 30 minutes of transcription. Basic: a 220,000-word limit, measured on English text. Pro: "unlimited", which the terms define as normal, reasonable, non-automated use.
→ Anyone transcribing many long podcasts each month has less metering to watch on Miraa Pro. On Corodomo, the AI hours spent on subtitles come out of the same allowance as speaking practice, so plan for both.
Languages covered[10],[11],[7],[13],[8],[15]Dedicated tools for Japanese (furigana, kaiwa, JLPT), English (IPA, TOEIC) and Chinese (HSK); no full list of study languages is published. Interface in 11 languages.The App Store description lists English, Japanese, Chinese, Korean, Spanish, German, Italian and French. Interface in nine languages.
→ Miraa publishes a broader list, so Korean or European-language learners know where they stand. Japanese, English and Chinese learners get extra dedicated tools on Corodomo.
Speaking feedback[5],[6],[12],[15],[17]AI scores each sentence and word, flags mispronounced or skipped words and comments on accuracy, fluency and completeness. 1:1 AI Coaching assigns shadowing tasks by level; CoroAI offers situational conversation.Practice follows a four-step "Echo Method": listen, understand, imitate, compare, repeating each line with an on-screen indicator. No pronunciation scoring is described.
→ If you want to know which words you got wrong, Corodomo provides that, though the accuracy of its AI scores has not been independently tested. On Miraa, comparing yourself with the original comes without a score or correction.
Other study tools[3],[7],[13],[15]In-context lookup, dictation, translation practice, quizzes, flashcards, summaries and mindmaps, plus JLPT, HSK and TOEIC practice. The quota guide lists these revision tools as not using AI hours.Real-time translation, AI explanations of words and grammar with follow-up questions, and "Delayed Reveal" subtitles that hold text back for listening practice. No curriculum or tests are described.
→ Corodomo suits learners who want to revise vocabulary, practise writing and prepare for exams on the same material. Miraa stays lean, focused on understanding and repeating each line.
Platforms[1],[2],[8],[9],[17],[21]Web, iOS and Android; Plus covers 4 devices.iOS and Android (Google Play or an APK from the homepage); the homepage mentions no web or desktop version.
→ Of the two, only Corodomo has a web version for studying on a computer or larger screen.
Paid plans for individuals[2],[15],[16],[19]Published in VND on corodomo.com (no official USD price recorded): Plus 179,000 VND/month (≈ $6.98/month) or 1,392,000 VND/year (≈ $54.26/year) (116,000 VND/month (≈ $4.52/month)); Pro 399,000 VND/month (≈ $15.55/month) or 3,156,000 VND/year (≈ $123/year) (263,000 VND/month (≈ $10.25/month)). One-off lifetime payments: Plus 2,990,000 VND (≈ $117), Pro 5,999,000 VND (≈ $234).US App Store: Basic $0.99/month (monthly only); Pro $5.99/month or $49.99/year ($4.17/month). The terms list Pro yearly at $59.99, which differs from the store price.
→ Comparing VND prices (Miraa's Vietnam App Store prices against Corodomo's website prices), Miraa is cheaper at both the entry and Pro level. Corodomo's price covers pronunciation scoring, AI speaking practice and AI Coaching, which Miraa does not describe, and adds a lifetime option.
Free plan[2],[3],[19]Limited video access, up to 3 imports and 1 AI hour/month. Watching subtitled library videos, lookup, dictation, translation, quizzes and flashcards do not use AI hours.30 minutes of transcription, per the terms of use.
→ Corodomo's free plan gives 1 AI hour a month and leaves revision tools unmetered. Miraa gives 30 minutes of transcription, and its terms advise trying the app before buying.
Refunds[4],[19]Web purchases are final except for duplicate charges, charges after cancellation, plans not activated within 7 days, a core paid feature down for more than 7 consecutive days through Corodomo's fault, or unauthorised transactions; claims within 30 days. App Store and Google Play purchases go through Apple or Google.The terms say subscriptions and one-time payments are non-refundable and advise trying the app before buying.
→ Neither refunds a change of mind, but Corodomo spells out when it will refund. With Miraa, use the free 30 minutes before paying.
Privacy[4],[18],[15]The policy names its AI processors (Soniox, OpenAI, Google Gemini, Anthropic Claude) and the data each receives, describes in-app consent and limits on training use, and offers access, correction, deletion and export by email; it does not download or store YouTube videos. No concrete retention periods.The policy (effective 15 Oct 2023) says audio and video files are deleted after recognition, translations are not stored and accounts can be deleted in-app; international accounts are stored in the US, China-region accounts in China. No AI provider or retention period for most data is named.
→ Corodomo says where your data goes; Miraa commits to deleting source files after transcription but does not say who processes them. Both are published-policy statements, not security audits.

Choose Corodomo if…

  • Learners who want word-level pronunciation scoring and guided shadowing at their level
  • Japanese, English or Chinese learners combining video study with JLPT, TOEIC or HSK practice
  • Learners who prefer a curated library by topic and level over finding material themselves
  • Anyone who needs a web version, not just phone apps

Choose Miraa if…

  • Learners who already have YouTube channels or podcasts in mind and just need bilingual subtitles to shadow
  • Budget-minded learners: Basic $0.99/month, Pro $5.99/month on the US App Store
  • Learners of Korean, Spanish, German, Italian or French, which Miraa lists on the App Store
  • Heavy podcast users who want Pro's unlimited transcription within reasonable use

The core difference: a guided library or a tool for your own media

Corodomo is built around a video library organised by topic and level, covering everyday life, business, IT, news and an IT Passport course. The Corodomo team says the library is selected and reviewed. You can still add your own videos, including from YouTube, but AI subtitles on imports should be checked.

Miraa works the other way round: paste a YouTube or podcast link (or pick a built-in podcast), and AI produces bilingual subtitles, translates as you watch and explains words and grammar on request. No curriculum or tests are described. If you already know which channels you want to learn from, Miraa is quick and lean; if you want direction, Corodomo is more structured.

Speaking practice: scored feedback or plain imitation

This is the clearest difference. Corodomo's AI scores each sentence and word, flags mispronounced or skipped words and comments on accuracy and fluency. 1:1 AI Coaching (on iOS since version 1.1.15, November 2026) sets tasks by goal and level and has you retry weak sentences; CoroAI adds situational conversation such as Japanese kaiwa. All of this feedback comes from AI, not a teacher, and no independent test of its pronunciation scores is available.

Miraa calls its approach the "Echo Method": listen, understand, imitate, compare. Version 1.15.2 (November 2026) made seeking and stopping more precise during shadowing. But no pronunciation scoring is described, so you get no score or word-level correction.

Prices, allowances and refunds

Among plans for individuals, Miraa costs less at every tier when both are compared in VND (its Vietnam App Store prices against Corodomo's website prices). On the US App Store, Miraa Basic is $0.99/month and Pro $5.99/month or $49.99/year, though its terms list Pro yearly at $59.99. Corodomo publishes prices in VND only: Plus 179,000 VND/month (≈ $6.98/month) or 1,392,000 VND/year (≈ $54.26/year), Pro 399,000 VND/month (≈ $15.55/month) or 3,156,000 VND/year (≈ $123/year), plus one-off lifetime options (2,990,000 and 5,999,000 VND (≈ $234)).

Allowances work differently too. Miraa Pro is "unlimited" within reasonable use. Corodomo meters AI hours (30 a month on Plus, 100 on Pro) shared across subtitle generation, detailed pronunciation scoring and speaking, while library videos, dictation and flashcards are unmetered. On refunds, Miraa's terms rule them out entirely; Corodomo refunds only in listed cases such as duplicate charges or prolonged outages on its side.

Devices, privacy and user ratings

Corodomo runs on web, iOS and Android; Miraa is iOS and Android only. On data, Corodomo names each AI processor and the data it receives, describes in-app consent and accepts deletion and export requests; concrete retention periods are missing. Miraa's 2023 policy says audio and video files are deleted after recognition and translations are not kept, but names no AI provider and no retention period for most data.

Both are well rated by users: Corodomo 4.9/5 on the Vietnam App Store (946 ratings) and 4.8/5 on Google Play (531); Miraa 4.58/5 on the US App Store (1,344 ratings), 4.76/5 on the Vietnam App Store (4,985) and 4.8/5 on Google Play (14,800). Miraa has a much larger rating base. AppDuo's overall scores are 8.5/10 for Corodomo and 7.2/10 for Miraa, but your specific needs should decide.
