About this app

AI Instant Caption is a real-time captioning and translation tool designed for video, live streams, meetings, online classes, and everyday communication scenarios.

Using on-device AI speech recognition technology, the application can quickly convert playing audio or microphone speech into text and display it as floating captions above other applications. The main recognition and translation process is completed locally on the device, balancing real-time performance with privacy protection.

We offer an option to earn free usage time by watching ads; each video ad extends usage time by 30 minutes. We also offer a highly competitive lifetime ad-free option.

【Main Features】

• Real-time Speech Captioning: Quickly converts speech to text, displaying it as you listen, reducing waiting time.

• System Audio Recognition: With user authorization, it can recognize audio from videos, live streams, courses, meetings, and other media playing on the device.

• Microphone Speech Recognition: Supports generating real-time captions via microphone, suitable for face-to-face communication, meeting recording, and language learning scenarios.

• Real-time Caption Translation: Supports translating recognition results into other languages, helping users understand foreign language videos, courses, and conversations.

• Floating Subtitle Display
Subtitles can be displayed above other applications, eliminating the need for frequent page switching.

• Local AI Processing
Major speech recognition and translation tasks run locally on the device. When using local recognition mode, the original audio is not uploaded to AVGAIGROUP's own servers.

• On-Demand Language Model Download
Users can download the corresponding speech recognition models or translation language packs as needed, reducing unnecessary storage usage.

• Flexible Subtitle Settings
Subtitle display, language, and related function options can be adjusted according to usage habits.

【Applicable Scenarios】

• Watching foreign language videos, live streams, and short videos

• Online courses and language learning

• Video conferencing and remote communication

• Face-to-face conversation assistance

• Hearing assistance and information comprehension

• Reading content when it's inconvenient to turn on the sound

【Permission Explanation】

To provide the relevant functions, AI Instant Captioning may request the following permissions:

• Microphone permission: For recognizing microphone voice

• Media casting or audio capture authorization: For recognizing audio played on the device after the user actively authorizes it

• Floating window permission: For displaying captions above other applications

• Notification and foreground service permission: For maintaining the captioning service

• Network permission: For downloading models, loading ads, and processing in-app purchases

These permissions are only used when required for the corresponding function. Users can revoke permissions at any time in the Android system settings.

【Privacy Protection】

AI Instant Captioning primarily uses on-device processing. In local recognition mode, audio is mainly processed on the user's device and is not uploaded to AVGAIGROUP's own servers.

This app may use Google Play Billing, Google Mobile Ads, Google ML Kit, and Google Play services. Related third-party services may process necessary device, network, purchase, advertising, or diagnostic information in accordance with their privacy policies.

Actual recognition speed and accuracy may vary depending on device performance, audio quality, ambient noise, speech pattern, and the selected language model.
Local AI real-time captioning and translation, supports system audio and microphone, fast, private, and low latency (no monthly subscription, almost completely free).
