85% of social media videos are watched without sound, and platforms like YouTube actively favor captioned content in recommendations. Yet most creators skip captions because they're tedious to create. Blazescribe's free caption generator fixes that.
Upload any video and get an SRT caption file with word-level timing in minutes. The captions are formatted for readability — natural line breaks, proper reading speed, and 98%+ accurate text. They work on YouTube, TikTok, Instagram, LinkedIn, and every major platform.
The free tier processes one video per day (25 MB max). For styled captions, burned-in text, VTT/ASS formats, and batch processing, upgrade to Pro.
