Kapwing drives user adoption by building AI-first features with AssemblyAI
Kapwing's previous transcription API lacked accurate word-level timing and foreign language translation, limiting the subtitle and caption features they could offer to a global user base.
How it works
Common implementation structure
How this type of workflow is generally built, generalized across documented cases — not tied to any one vendor's stack. Click any stage to read what happens there. Specific products that implement these stages appear in “Tools commonly seen” below.
Stage 1 · User needs video subtitles
Users want subtitles and transcriptions because videos are commonly watched on mute.
Tools used
AssemblyAI
Outcome
Switching to AssemblyAI enabled Kapwing to offer precise word timings, word-by-word animations, and foreign language translations, with transcriptions and translations becoming a major driver of revenue.
What failed first
Their previous speech API did not deliver accurate word-level timing or foreign language translation support, prompting a vendor switch.
