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.
OCR subtitle extraction uses optical character recognition to detect and extract hardcoded subtitles from video frames.
Pick the subtitle color and region, and GeekLink converts burned-in subtitles into clean, editable SRT files — batch across a whole season, fully on-device.
AI line-breaking re-splits subtitles at natural sense-group boundaries instead of fixed character lengths, so every line reads cleanly.
Auto-generated subtitles break mid-phrase, strand words on prepositions, and run too long. GeekLink's AI re-breaks each cue where it makes sense — automating one of the most time-consuming manual cleanups in subtitling, so lines read the way a person would write them.
Subtitle review flagging marks the lines most likely to be wrong — low-confidence words and segments covered by music — so you check a shortlist instead of the whole transcript.
After recognition, GeekLink flags the exact low-confidence word in each risky line and the segments where music may cover speech, then exports a review pack (SRT + clickable bookmarks + video). You jump straight to what needs checking — cutting review time without skipping QC.
Speech-to-text (ASR) automatically transcribes spoken audio in a video into text subtitles using AI.
Powered by Whisper and fully on-device, GeekLink turns speech into timed, editable subtitles — ready to translate and burn in, nothing uploaded.
AI translation uses large language models (LLMs) to intelligently translate video subtitles from one language to another.
Context-aware AI translation (Claude, GPT-4o, DeepSeek) across 40+ languages, with bilingual export — from a video or an existing SRT file.
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. Or point GeekLink at a watch folder and every new video is processed automatically.
GeekLink supports speech recognition and translation for 40+ languages, covering the world's major languages:
GeekLink uses OpenAI Whisper, supporting 40+ languages with 95%+ accuracy. For clear dialogue audio, accuracy typically exceeds 98%.
GeekLink's OCR feature extracts hardcoded subtitles from video frames. It supports multiple languages and fonts, with color filtering and region selection.
Yes, AI translation uses cloud-based models like DeepSeek and requires an internet connection. Speech recognition and OCR work offline after the initial model download.
GeekLink supports common video formats including MP4, MOV, MKV, and AVI. MP4 or MOV is recommended for the best experience.
