Khao Jai เข้าใจ
Read full descriptionHide full description
Khao Jai is a translation app built for one thing: conversations between Traditional Chinese and Thai. Not swapping words between languages. Letting two people finish a conversation. ■ Register and speaker gender change the Thai Thai particles shift with the speaker's gender and how close you are. Switch between formal, everyday, and intimate; switch speaker gender. "Sure" said to your boss shouldn't look like "sure" said to a friend. ■ Hold to speak Hold the mic, say a sentence, release. Audio is sent for transcription and deleted immediately afterward — never stored. ■ Tell us when it's wrong Every translation can be reported, and reports go straight into our correction queue — not into an inbox nobody reads. ■ Start free 5,000 characters of translation, all-time (no monthly reset), plus 60 seconds of voice per day. Subscribe only if it earns it. Out of free quota? You can choose to watch one ad for 500 more characters of text translation (subscribers never see ads; not available in some regions). Pro: 100,000 characters per 30 days. MAX: 500,000 characters per 30 days. Subscriptions renew automatically and can be cancelled anytime in App Store account settings.

Verdict
The clearest difference is in-app purchases: PrimeVolt at none against Khao Jai เข้าใจ's 2. PrimeVolt also leads on ads (none vs shown) and device support (3 vs 1). Khao Jai เข้าใจ's advantage is update cadence (every 2 weeks vs every 6 weeks). On price there is nothing between them.
