## Checksub

Checksub is a video localization platform built around subtitles. You upload a video, and the service automatically transcribes the speech, generates synchronized captions in the original language, and lets you restyle or animate them with dozens of presets — including one-click karaoke effects. From that base transcription it can then translate the whole script into more than 200 languages, keeping the timing and line breaks appropriate for on-screen reading rather than a raw machine translation.

Beyond subtitles, Checksub handles AI dubbing: it isolates the original voices from music and background noise, then regenerates the dialogue with realistic AI voices while preserving the rest of the audio atmosphere. Voice cloning lets you substitute a cloned version of your own voice in some 30 languages, and a script-to-subtitle mode converts an existing written script into perfectly synchronized captions without transcription errors.

Everything is editable in an online editor, so once the AI has produced subtitles or a dub you can rewrite, re-time, regenerate individual sentences, and export either burned-in video or subtitle files. The platform is aimed at training departments, social media teams, YouTubers and agencies that need to publish the same content in many languages without re-shooting.

**Pricing & Plans:** Checksub offers a free trial that includes credits covering roughly one hour of video and access to every feature. Ongoing use is on paid subscription plans; exact tiers and per-minute limits are shown on the Checksub pricing page, and larger teams can book a demo for custom quotes.

- **Automatic subtitling and animation:** Generates accurate captions with AI, then lets you apply dozens of style presets and animations, including one-click karaoke effects, before exporting burned-in video or subtitle files.
- **Translation into 200+ languages:** Machine translation built specifically for subtitles, so line lengths and timing stay readable instead of copying a generic document translator.
- **AI dubbing with voice isolation:** Separates music and background noise from the original voices, then replaces only the speech with realistic AI dubbing so the audio atmosphere is preserved.
- **Voice cloning in 30 languages:** Clone a speaker's voice from a sample and use it to replace the original voice-over across dozens of languages with a natural delivery.
- **Advanced online editor:** Edit, re-time and regenerate any subtitle line or dubbed sentence directly in the browser, with script-to-subtitle alignment for pre-written content.

**Strengths:** Subtitle, translation, dubbing and voice cloning live in one workspace; Purpose-built subtitle translation keeps line lengths readable; Voice isolation preserves music and ambient audio in dubs; Free trial credits cover about an hour of video, enough to test real workflows

**Limitations:** Credits are consumed per language created, which adds up for multi-market projects; The free trial is short-lived and paid plans are subscription-based; The editor has many options, so new users need some time to learn the interface

## LingoSub

LingoSub is a browser-based language-learning service built around comprehensible input. Rather than drilling isolated vocabulary lists, it uses genuine videos — vlogs, comedy, music, cartoons, news and lessons from native creators — and layers word-by-word subtitles, sentence translations and grammar notes on top of the official YouTube player. A three-minute vocabulary test estimates how many words you know and places you between A1 and C2, then the library surfaces videos matched to that level so you already understand most of what you hear.

During playback, each word is highlighted as it is spoken, with its meaning in that specific sentence shown above it, along with its dictionary form, part of speech, frequency and a note where the grammar or slang needs explaining. Idioms and separable verbs are treated as single units. Learners who want more support can show translations over every word; as they improve they can switch to only-unknown-word translations or turn them off entirely. Playback speed is pre-matched to both your level and the speaker's pace, and you can replay a sentence, auto-pause after each one, or slow things down.

Free access covers every video and story with subtitles and sentence translations plus the level test, with no account required. LingoSub Pro adds per-word translations, tappable word meanings and grammar, native pronunciation and a saved-word list. The library currently spans French, German, English, Italian, Russian, Latin, Romanian, Norwegian, Spanish, Korean, Japanese and Portuguese, with roughly 3,600 videos rated from A1 to C2.

**Pricing & Plans:** Free tier includes all videos and stories with subtitles and sentence translations, plus the level test with no sign-up. LingoSub Pro is listed at $12 per month or $99 per year and unlocks per-word translations, word meanings and grammar notes, native pronunciation and saved words.

- **Word-by-word timed subtitles:** Every word is transcribed with its own timing so it highlights exactly as it is spoken, with the meaning in that sentence displayed above it.
- **3-minute vocabulary level test:** A no-signup test estimates how many words you know and places you from A1 to C2, then recommends videos matched to that level.
- **Context-aware word and grammar notes:** Tap any word for its dictionary form, part of speech, frequency, in-sentence meaning and a note explaining the grammar, slang or expression.
- **Adaptive translation display:** Show translations over every word as a beginner, switch to only unknown words as you improve, or turn them off completely.
- **Level-matched native video library:** Thousands of real YouTube videos across 12 languages rated from A1 to C2, playable in the official YouTube player.

**Strengths:** Learns from authentic native content instead of scripted textbook dialogues; Word-level timing and in-context explanations go far beyond plain YouTube subtitles; Free tier covers all videos, stories and the level test with no account; Supports twelve languages with CEFR-rated libraries and per-language level tests

**Limitations:** Codeswitching-heavy videos may still overwhelm absolute beginners despite translation support; Videos are hosted by YouTube, so playback depends on that platform being available; Advanced word meaning, grammar notes and saved words are locked behind the Pro subscription
