Our Story
Hey Subtitle was born from a real creator's pain point. Founder Mr. K is a well-known Hong Kong urban exploration YouTuber who films extensive exploration content that requires constant narration — making the subtitle workload enormous. Using tools like Subanana in the past, the pricing was steep and AI transcription accuracy was far from ideal, often requiring hours of manual corrections.
Subtitles were only half the problem — narration ate just as much time. Recording a voiceover meant memorising a script minutes long, then delivering it in one clean take. One stumble or misread and it was either start over or hide the seam with a jump cut in the edit, leaving the footage more fragmented and the production longer every time. With voice cloning and text-to-speech, the script is simply pasted in and read back in his own voice — no memorising, no retakes, no chopping up footage to cover a slip. Those hours once spent recording and re-shooting go back into the work itself.
At a YouTube creator event, Mr. K met the CEO of CantoSubAI, and the two discussed the many challenges of subtitle creation. The CEO was young and talented, with a very professional product — this encounter deeply inspired Mr. K and strengthened his resolve to build his own tool. Drawing on years of professional experience in information technology, Mr. K built this platform from scratch, single-handedly — countless sleepless nights, all to bring this "baby" to life.
After launch, Mr. K discovered that entrepreneurship isn't just about writing code — it also involves managing social media, producing tutorial videos, and marketing. Every step was a brand new learning experience. The platform grew too: starting from subtitles, it became text-to-speech, voice cloning and AI dubbing, with the original subtitle toolkit still in place. The name Hey Subtitle keeps that starting point, but the original vision never changed: to let every content creator speak in their own voice, saving time for what truly matters — creating.
