Alion Tech Studio Audiogram Maker vs CapsAI

Alion Tech Studio Audiogram Maker is a free web tool that turns audio clips into waveform videos with sound. It accepts MP3, WAV, M4A, OGG, and FLAC files. You can trim a clip, add a title, subtitle, cover art, and optional background image, then customize waveform and background styles. Export layouts include square 1080×1080, vertical 1080×1920, portrait 1080×1350, and wide 1920×1080. Chrome, Edge, and Firefox produce WebM files with Opus audio, while Safari produces MP4. Clips can be up to three minutes, and exporting takes about as long as the clip because recording occurs in real time. Audio is decoded, analyzed, and recorded in the browser; the page says files are not sent to a server. No account is required, and preferences remain in browser storage until site data is cleared. The free plan costs nothing, has no watermark or upload, and allows unlimited exports.

CapsAI generates and edits subtitles for videos, including English, Hindi, Hinglish, and regional languages. The workflow is to upload an MP4 or MOV, select the spoken language, generate captions, review and correct the text, then export a captioned MP4. The current uploader lists Hinglish, English, Hindi, Bengali, Telugu, Marathi, Tamil, Urdu, Gujarati, Kannada, and Punjabi. Edited SRT and VTT downloads are not exposed in the editor, and direct URL transcription is not part of the current workflow. CapsAI says its browser workflow works on iPhone, Android, tablets, and desktop devices. The free plan page shows zero minutes left, while an API information page states a current free allowance of three minutes. Starter costs ₹49, paid once for 20 upload minutes, 1080p export, and three days of project storage. Creator costs ₹99, paid once; Pro costs ₹299, paid once. The product describes users including creators, agencies, educators, founders, and marketers.
