SyncTalk: Live Interpreter

SyncTalk interprets speech as you speak, with source and translated captions plus spoken translations for travel, everyday conversations, and cross-language communication.

• Try without a key: one lifetime five-minute managed trial per App Store account. • BYOK Lifetime: a one-time purchase unlocks your own API key. Provider usage fees are separate; managed monthly minutes are not included. • Managed Monthly: an auto-renewing monthly subscription includes 300 minutes per active billing period. Connected time, including silence, uses the allowance. Minutes do not roll over; the allowance resets next period. No automatic overage charges. • View source and translated captions together. Save snapshots on your device, review, delete, or share them. • Use headphones, the built-in microphone, or the speaker, with selectable target languages and voices. • Two-person conversation mode selects the translation direction between two languages. When separate audio routes are unavailable, the app explains the fallback; shared-microphone translations play after the language is confirmed. • Voice cloning is available with the managed trial, monthly plan, and BYOK. Clone once or for every sentence after obtaining the speaker's consent. Clone-once mode extracts the voice again for each new connection.

Once a managed session starts, it is not interrupted solely because its allowance runs out or a set amount of time passes. The balance is deducted only down to zero, and each new connection checks the allowance again. End a managed session before changing its language. App Store storefronts in mainland China, Hong Kong, and Macao use the Beijing translation provider; other or unavailable storefronts use Singapore. This does not guarantee that all Cloudflare processing or network transit stays in that region.

Prices are shown in your local currency before purchase. Monthly subscriptions renew automatically and can be canceled in Apple's subscription settings. Deleting your cloud account does not cancel a subscription. BYOK supports Restore Purchases and official Apple offer codes. Previous-version usage does not automatically grant a paid entitlement.

After audio input stops, received translated speech can finish playing. The app may queue pending translated speech in private temporary files on your device and deletes played segments. Choosing “End Now” cancels waiting and playback.

The SyncTalk backend keeps only minimal account, authentication, and usage data. It does not persist audio, source text, or translations. Your own API key stays in the device Keychain and connects directly to your selected provider. Delete your cloud account from Translation Plans; minimal spent-trial markers remain to prevent duplicate allowances. See the privacy policy for details.
