Caplo: AI Live Captions
Translate Apps with Subtitles
Free · In‑App Purchases
Caplo turns speech into live captions and translates them as you listen, on iPhone and iPad.
Read along with conversations, lectures, in-person meetings, videos, live streams, and podcasts. Capture speech through your microphone or audio playing in supported apps, then follow captions in a floating Picture-in-Picture window.
LIVE SPEECH-TO-TEXT
See spoken words as text while you listen. Use live transcription to follow a speaker, revisit an explanation, or keep a readable record of a session.
REAL-TIME TRANSLATION
Translate captions into 60 languages, including English, Chinese, Japanese, Korean, Spanish, French, German, and Portuguese. Read captions in the original language, or switch to translated captions when you need help understanding another language.
TWO WAYS TO CAPTURE AUDIO
• Microphone: Capture nearby speech for face-to-face conversations, classroom lectures, and in-person meetings.
• System Audio: Capture audio playing in supported apps through iOS screen recording, including videos, live streams, podcasts, and online courses.
FLOATING CAPTIONS
Keep captions visible in a Picture-in-Picture window while using other apps. Follow the audio without repeatedly switching back to Caplo, and customize caption styles to suit your reading preferences.
SAVE, SEARCH, AND EXPORT
Sessions are saved automatically so you can review them later. Browse and search your history, copy text, or export transcripts as Markdown for study notes and meeting records.
Your sessions are stored on your device and sync automatically across your devices when iCloud Drive is on.
FOR EVERYDAY LISTENING AND LEARNING
• Conversations and in-person meetings: Read what is being said and review the transcript afterward.
• Classes and lectures: Follow explanations and revisit useful passages.
• Cross-language listening: Use translated captions to help understand speech in another language.
• Videos, live streams, and podcasts: Read captions while supported apps play, even when suitable subtitles are unavailable.
CAPLO PRO AND CREDIT PACKS
Continued use of transcription and translation requires a Caplo Pro subscription.
• Caplo Pro: A monthly subscription with 600 minutes of transcription each month and every feature included.
• Credit Pack: For Caplo Pro subscribers. A one-time purchase of 600 extra minutes that add to your monthly minutes and never expire.
Prices are shown in the app. Subscriptions renew automatically unless canceled at least 24 hours before the current billing period ends. Manage or cancel your subscription in your App Store account settings.
BEFORE YOU START
Audio capture depends on the source app and content. Caplo does not support capturing call audio from video calling or online meeting apps. Use microphone mode for in-person meetings.
