What's included in each tier, side by side.
| Feature | Free | Basic | Pro | Backer |
|---|---|---|---|---|
| Translation | ||||
| Dual subtitles Original-language and translated captions stacked together while you watch. | ||||
| 70+ languages We support 71 languages with varying levels of support. AI vocab-card quality varies — 41 languages have per-language prompts tuned for their grammar; 30 fall back to family-level defaults that improve over time. | ||||
| Translate anything, even pirates Translate captions in any style you want — pirate, Shakespearean, formal, casual, dialect, period-accurate, you name it. Available on all paid plans. | — | |||
| Hover translation Hover any word for an instant translation popup. Free: standard machine translation. Paid: context-aware AI model. | Machine | AI | AI | AI |
| Word & phrase lookup Click a word or select a phrase for a detailed translation. Free: standard machine translation. Paid: AI model. | Machine | AI | AI | AI |
| Context-aware translations AI reads neighboring subtitle lines (and idiom hints, scene tone, and your prior translations) before translating the current cue — so pronouns, callbacks, and tone stay consistent across the scene instead of being re-guessed line by line. | — | |||
| AI translation — Fast Lightweight AI model. Lowest credit cost and quickest response. Good for casual watching where you want translations to keep up with the video. | — | |||
| AI translation — Balanced Mid-tier AI model. Better grasp of context and idioms than Fast, but noticeably slower to respond and costs more per request. | — | |||
| AI translation — Best Top-tier AI model. Highest translation quality, but the slowest to respond and the most expensive per request — best for pausing and studying a line, not for real-time watching. | — | |||
| Learning | ||||
| AI vocab cards (save → expand) Save a word and an AI fills in a full study card: lemma, part of speech, every inflected form, and multiple senses with example sentences. | — | |||
| Idiom detection (inline) AI spots idioms in the subtitle line as you watch and shows an explanation in your native language. | — | |||
| Idiom library + sets Saved idioms live in your account library, organized by language. Create sets from saved words and phrases to help you learn. | — | |||
| Lookup library Every word and phrase you saved while watching, organized by language and part of speech. | — | |||
| Study mode In Progress Gap-fills, matching, and drag-to-reorder quizzes built from words you actually encountered. | — | |||
| Quotas | ||||
| AI credits / month Each AI translation request consumes credits. Cost varies by quality level — Fast is cheapest, Best is most expensive. Resets monthly. | — | 2,500* | 15,000* | 40,000* |
| Hydration credits / month Hydration unlocks a saved word with our highest-quality model — every form, every sense, with example sentences. Cards are standardized and maintained by volunteer Contributors who keep accuracy high. | — | 5* | 15* | 30* |
| Hydrations à la carte Out of hydrations before your monthly reset? Top up your wallet ($10 minimum) and pay per hydration as you go — no plan upgrade needed. | — | |||
