Features

Reels Studio is a free browser-based toolkit for short-video creators. It combines music BPM detection, subtitle generation and script segmentation in one flow, so you can go from an audio file and a script to beat-synced subtitles and a shot-by-shot segment plan without switching between several tools. Upload a track and the built-in analyzer finds the tempo; paste your voice-over script and the studio splits it into cues, optionally snapping every subtitle to the beat grid; then split the script into 15-second, 30-second or 60-second clips for posting. Everything runs locally in your browser, so your audio is never uploaded. The free plan includes full BPM detection, subtitles and segmentation. PRO members get unlimited AI hook, caption and hashtag suggestions plus private cloud projects that sync across your devices.

Reels Studio is a free short-video toolkit that detects music BPM, generates beat-synced subtitles from your script, splits the script into 15s / 30s / 60s clips and exports SRT, segment plans and BPM cards, with all core features free and a PRO plan for unlimited AI suggestions and cloud projects.

When You Need This

Common pain points this tool solves

1. You edit short videos and need the subtitle timing to land exactly on the beat of the background music.
2. You record voice-over videos and want to split a long script into 15-second, 30-second and 60-second versions for different platforms.
3. You post on TikTok, Instagram Reels and YouTube Shorts and need captions, hooks and hashtags for every clip.
4. You are a content team preparing a batch of videos and need a consistent segment plan and subtitle files for the editor.

How to Use

Step-by-step instructions

2. Paste your voice-over script in step 2 and choose how to split it into subtitle cues.
3. Enable beat-synced subtitles so each cue snaps to the beat grid detected from your music.
4. In step 3 choose 15, 30 or 60 seconds per segment and review the split plan.
5. Use step 4 to generate AI hooks, captions and hashtags, then export the SRT files, segment plan and BPM card in step 5.
