Trainn lets us record videos and add speech in a jiffy. The Video engagement data helps us understand how the videos are fairing — Rwiddha Mitra, HackerRank 🏆 For the first time, our product team is not perturbed by the thought of making a product video. It brings in a layer of professionalism that we require and enables us to seamlessly merge the video with the subtitles to make it feel rehearsed and effortless. — Nikhil G, Limechat 🏆Our customers always ask for quick 1-minute tutorial videos to learn the product. It took exactly 45 days to create over 100 tutorial videos, review, and publish the Learning Center on Trainn. — Sabina Rana I Dangal, Head of Support, BuildOps 🏆The best feature is that you can auto-translate a single video into multiple languages. — Shambhavi Pandey, Manager, RestroWorks Academy (previous Posist) 🏆We needed a tool to easily create training and support videos in multiple languages despite our English-only support staff. Trainn’s unique functionality for screen capture + video + closed captions + natural sounding text to speech was the perfect combination for our needs. Other vendors in the space did a solid job with 2 of 3 requirements, but not all four. Additionally, I can't say enough about their excellent support. — Henry C, LocalClarity ------------------------------------------------------------------------------------------------------------------------------------------------- ✳️ Key features: Record any workflow ‣ Trainn helps record your Chrome tab, entire window, or full screen. ‣ Record stunning Full HD, 1080p quality videos by default. ‣ Create engaging video presentations.
