        "longDescription": "Harmar adds subtitles to your videos. Attach a video and Harmar transcribes the speech, times every word, and returns a captioned MP4 for Instagram Reels, TikTok or YouTube, or an SRT/VTT subtitle file for your video editor.\n\nMade for speech that mixes languages. Many people switch languages on camera: Hinglish, Spanglish, Taglish, French or Portuguese with English, Armenian, Ukrainian or Kazakh with Russian. Harmar transcribes mixed speech as it was said, writing each word in the language and alphabet it was spoken in. On real code-switched recordings it measured a 6.6% average word error rate.\n\nWorks in 63 languages, with the spoken language detected automatically. On the public FLEURS benchmark it measured an 8.1% average word error rate across 57 languages, including languages such as Georgian, Armenian, Uzbek, Kazakh, Kyrgyz, Tajik, Mongolian, Maltese, Swahili and Yoruba. Per-language results and method: https://harmar.ai/en/blog/whisper-accuracy-benchmark-59-languages\n\nUseful for client videos, interviews, podcasts, courses, ads and short-form content.\n\nWhat you can do:\n\u2022 Get subtitles for a video you attach or share as a link.\n\u2022 Translate the subtitles into another supported language, giving the video a second subtitle track.\n\u2022 Choose a caption style (karaoke word highlights, pill highlights, pop-in words or classic subtitles), adjust colours and fonts, and save it for later videos.\n\u2022 Download the captioned MP4 or an SRT/VTT file.\n\u2022 Open any video in the Harmar web editor to change a word or adjust timing.\n\nHarmar works with your Harmar account; you sign in the first time you use it. Harmar does not generate video, audio or images: it transcribes the speech in your own video and renders it as subtitles.",
