Overline

Product Introduction

1. Definition: Overline is a real-time AI speech-to-text and translation browser extension for Google Chrome. It functions as an on-screen captioning tool that transcribes and translates live audio from any browser tab without requiring built-in subtitles or page modification.

2. Core Value Proposition: Overline eliminates language and comprehension barriers in video content by providing instant AI-generated captions and live translation directly overlaid on any playing video, whether on streaming platforms, educational sites, or video calls. Its primary purpose is to make all audio content accessible and understandable in the user's preferred language in real-time.

Main Features

1. Real-Time Transcription: Overline delivers sub-second latency captions powered by Deepgram's streaming speech recognition API. It captures the live audio stream from the browser tab and displays transcribed text as an overlay, keeping pace with the speaker with an average latency of approximately 112 milliseconds. This feature works independently of any existing subtitles.

2. Instant Translation: The tool provides real-time translation for 10 languages, including English, Persian, German, Japanese, Korean, Portuguese, Spanish, French, Arabic, and Chinese. Translation is performed live as words are spoken, allowing users to switch target languages per session instantly without reloading the video or changing tabs.

3. Session Transcript History: After each viewing session, Overline saves the full text transcript to the user's account. Users can download transcripts in TXT or SRT format, which is ideal for creating study notes, generating subtitles for personal use, or reviewing content after the fact. The system maintains a log of past sessions for easy access.

Problems Solved

1. Pain Point: Overcome the lack of native subtitles or accurate closed captions on a vast amount of online video content, including lectures, live streams, and international media. It solves the problem of language barriers for non-native speakers and the inefficiency of switching tabs to use separate translation or transcription tools.

2. Target Audience: This tool is essential for online learners (using Coursera, YouTube lectures), international entertainment viewers (Netflix, Twitch), remote professionals (Zoom meetings), and language learners who need real-time support.

3. Use Cases:

   • Watching a German-language documentary on Netflix with live English captions.
   • Following a fast-paced English coding tutorial on YouTube with translated captions in your native language.
   • Reviewing a recorded Zoom meeting with a generated transcript for accurate minutes.
   • Studying a Japanese lecture on Coursera with subtitling in Spanish for parallel language learning.

Unique Advantages

1. Differentiation: Unlike traditional subtitle files (.srt) that must be manually found, matched, and loaded, Overline works automatically on any video. It surpasses standard browser translation features by providing a dedicated, non-intrusive overlay that doesn't alter the page structure or require file uploads.

2. Key Innovation: The core innovation is its "no page injection, pure live audio streaming" architecture. It captures audio directly from the browser tab's audio output stream for processing, ensuring compatibility with DRM-protected content (like Netflix) and site integrity. Combined with Deepgram's streaming transcription, this delivers industry-leading low-latency captions.

2. Is Overline recording my voice or stealing my data? No. Overline streams your browser tab's audio output (the sound you hear) directly to the transcription service (Deepgram) in real-time. It does not access your microphone, personal files, or inject code into web pages. Session transcripts are saved to your account for your use only.

3. What languages does Overline support for translation? Overline supports live translation into 10 languages: English, Persian, German, Japanese, Korean, Portuguese, Spanish, French, Arabic, and Chinese. You can switch between these target languages during any session.

4. How is a "minute" counted in the pricing plans? A "minute" refers to one minute of active audio processing. If you use captions for 15 minutes on a video, it deducts 15 minutes from your monthly allowance. Time is counted only while captions are actively running.
