FAQ

Clear answers before you need to ask.

01How do I start?

After installing, hold Shift and hover a word to see its definition beside the text. When context matters, continue from the bubble or selection toolbar to ask, translate, or listen. Every shortcut is configurable.

02Which languages are supported?

You can currently read English, French, Japanese, Spanish, German, and Korean. The interface and AI answers follow 14 native languages; some dictionary definitions are shown in English.

03Why does AI require sign-in?

Local dictionaries, word audio, resurfacing, and the PDF reader work without an account. Email-code sign-in unlocks 200 lifetime AI requests and a sentence-speech preview, links subscription status, and prevents automated trial abuse.

04What counts toward the trial?

A context explanation, selection explanation, paragraph translation, or voice answer uses one AI trial request. Transcription is included with a voice answer and is not charged twice. Sentence speech has a separate preview pool metered by text length. Local lookup, system word audio, and shadowing are free. A small daily taste remains after the lifetime AI trial is used.

05How is reading content handled?

Only when you actively use AI are the relevant words or sentences and nearby necessary content used to generate an answer. Whole pages are not sent by default. Local lookup does not upload page text. See the privacy policy for details.

06What PDF files work?

PDFs with selectable text support lookup, explanations, and speech. Scanned PDFs do not have usable text and are not supported for these features.

07How do cancellation and refunds work?

Cancel through Creem customer access or contact support@linknows.fun. Cancellation stops the next renewal and Pro remains active through the paid period. Your first monthly or annual purchase has a 14-day no-reason full-refund window. Renewals do not receive that window, and statutory refund rights remain unaffected.

08Will yabt translate whole pages or add flashcards?

No. yabt focuses on immediate questions while reading. Translation is explicit and paragraph-level, and there is no flashcard or review queue.
