About
SignCaption is a purpose-built accessibility platform that uses advanced AI Sign Language Recognition (SLR) to automatically generate captions from sign language videos. Powered by Sign-Speak — described as the world's best sign language AI — it streamlines the workflow for anyone creating or consuming signed content. The free Lite plan provides a fully-featured manual captioning and subtitle editor with video export, making it ideal for international users and those who want granular control over their captions. The Pro plan unlocks automatic ASL-to-text captioning, AI voiceovers, and 60 minutes of auto-captioning per month. Enterprise plans support schools and organizations with batch processing, custom workflows, and premium onboarding. Key features include Auto-Grammar Correction, AI Voice Over generation, loop/repeat playback, and video export. SignCaption is used by content creators publishing on YouTube, TikTok, and Reels; ASL learners and educators; Deaf and Hard of Hearing individuals; and enterprise teams building accessible video pipelines. Trusted by over 10,000 users, SignCaption is built around Deaf experiences with a mission to empower Deaf lives through technology — not just accommodate them.
