AudioTextify: Turning Audio Into Usable Content
Meetings, interviews, lectures, and video content generate a significant volume of spoken information that most people cannot practically use after the fact. AudioTextify was built to close that gap, transcribing spoken content and turning it into something you can search, summarize, translate, and repurpose.
Built as a Chrome extension, it works where the content already is: no download, no upload, no workflow change required.
What We Built
AI Transcription Engine
- Accurate speech-to-text for audio and video content playing in the browser
- Multi-speaker recognition that labels who said what
- 99 language support, covering both transcription and translation
- Real-time processing with low-latency output
Content Generation Layer
- Automatic summarization: key points extracted without manual review
- Blog and article generation from transcript source material
- Social media content drafts derived from the core ideas
- Meeting summary generation with action item extraction
Chrome Extension Architecture
- Sidebar-based UI that stays available without interrupting the main content
- Minimal permissions model: only accesses audio from the active tab
- Works across YouTube, recorded meetings, podcasts, and browser-based video
- Sync across devices for users with multiple workstations
The Engineering Approach
A Chrome extension that processes audio in real time has a tight constraint: it cannot meaningfully delay the user's experience. We built the processing pipeline to run asynchronously: the extension captures audio, batches it for transcription, and updates the transcript progressively without blocking the video playback or requiring the user to wait for a complete file before seeing results.
For translation, we implemented a two-pass approach: fast machine translation for immediate output, followed by a refinement pass that improved accuracy for technical and domain-specific vocabulary.
My Role
- Led product design and Chrome extension development end-to-end
- Designed the transcription interface and content generation workflow
- Built the audio processing and AI pipeline architecture
- Managed Chrome Web Store submission and compliance
- Optimized for performance within browser extension constraints
