AI Subtitle Factory

GeekLink is a macOS desktop app. Batch import dozens of videos, then auto-transcribe, translate (40+ languages), and burn-in subtitles — one pipeline, all locally on your Mac.

AI Speech-to-Text Subtitles

Speech-to-text (ASR) automatically transcribes spoken audio in a video into text subtitles using AI.

GeekLink integrates OpenAI Whisper, supporting 40+ languages with 95%+ accuracy. Everything runs locally on your Mac — no cloud uploads, full privacy.

Supports automatic language detection or manual selection. Generated subtitles can be edited, translated, and burned into the video directly.

Speech-to-Text ASR AI Engine Voice Recognition

Smart OCR Subtitle Extraction

OCR subtitle extraction uses optical character recognition to detect and extract hardcoded subtitles from video frames.

GeekLink uses the RapidOCR engine to quickly recognize on-screen subtitle text. Supports color filtering, region selection, and manual correction.

Extracted subtitles can be exported as SRT files or translated into other languages directly within the app.

AI-Powered Translation

AI translation uses large language models (LLMs) to intelligently translate video subtitles from one language to another.

GeekLink supports DeepSeek and other AI models for subtitle translation, covering 40+ languages: English, Chinese, Japanese, Korean, Thai, French, German, Spanish, Russian, Arabic, Italian, Portuguese, Dutch, Turkish, and more.

Compared to traditional machine translation, AI translation better understands context and domain terminology, delivering significantly higher quality.

Subtitle Burn-in & Export

Subtitle burn-in (embedding) renders translated subtitles directly onto the video frames, producing a new video file with hardcoded subtitles.

Customize font, color, size, and position. Export subtitled videos with one click — no need for Premiere, Final Cut, or other professional editing software.

Batch process dozens of videos at once — an entire short drama series, a YouTube channel, or hundreds of training videos. Import once, let the pipeline run.

Watch Folder Automation

Watch Folder monitors a directory and automatically processes every new video file — transcribing, translating, and exporting subtitles without manual intervention.

Point GeekLink at any folder on your Mac. When new video files (MP4, MOV, MKV, M4V, WebM) appear, they are automatically imported and processed through the full Whisper speech recognition and translation pipeline. SRT files are exported to the same directory.

Ideal for high-volume workflows: YouTube creators, subtitle translators working through episode batches, or localization teams processing client deliverables. Configure once, drop videos in, collect subtitles out.
