Create an account to generate and export your captions.

Fast clips need instant context

Clippers pull the best moments from a live stream, trim them to a few seconds and post them while the hype is still hot. Most viewers watch those clips on mute, so the reaction must be clear without sound.

Sycamore transcribes the spoken reaction, gives you word‑level timing and lets you fix any misheard word without losing the sync. Then you pick a template and export an MP4 ready for TikTok, YouTube Shorts or Instagram Reels.

Common caption pitfalls that mute the impact

Leaving captions at the bottom where the streamer's overlay sits.

Put captions at the top or center so the overlay stays visible.

Using a font color that blends with the game’s UI.

Choose a high‑contrast text or highlight color that stands out.

Showing a full sentence during a rapid reaction.

Lower words per line so each burst of speech appears in a quick, readable chunk.

Exporting in a landscape format for a vertical platform.

Export in 9:16 or 1:1; Sycamore keeps the aspect you need.
