Show HN: Scrolling Text – animated text overlays in the browser

Vertical scrolling text captions made for TikTok and short-form video — 9:16 presets, generated in your browser, exported in seconds.

Apply a look while keeping your text and voice choice.

0% is top, 100% is bottom. Safe margins keep text and glow inside the canvas; bars and labels move together.

2× and 4× export support WebM and MOV. GIF remains at base resolution.

Choose whether to include audio, then generate a voiceover below. Your choice is kept.

PNG MOV preserves transparent color and glow for compatible editors. Saves directly to disk in desktop Chrome/Edge; files can be hundreds of MB. Keep this tab active.

GIF uses 1× resolution and supports animations up to 20 seconds. Embed code is silent.

Editing and export stay in your browser. Cloud save uploads a design only when you choose it.

Generate once, then adjust Speed and Pitch locally without using more voice credits. Preview and export use the same audio.

Voiceover is being prepared. Animation tools remain available.

Speed preserves your selected Pitch. Only text or voice changes require generation again.

Saved only in this browser. Clearing browser data removes projects.

Loops everywhere — editors, chat apps and platforms that don't accept video overlays.

Higher quality at smaller sizes, with an optional transparent background for overlays.

Paste a snippet into any site that accepts custom HTML — no plugin or build step.

Choose WebM export and enable the transparent-background option. The file contains VP9 Alpha; your footage stays visible underneath when the receiving app supports that transparency format. Some editor versions or import paths show a black background instead. Test a short overlay in your editor before exporting the full design.

Yes. Export a looping GIF for universal compatibility or a WebM video for higher quality and smaller size, including a transparent-background WebM. Websites can use the embed code instead of a file.

Export your caption as a GIF or WebM, then import it on a track above your footage. Format and transparency support depend on your editor and version. If WebM Alpha shows black, export with a solid green or blue background not used in your design and apply Chroma Key. Soft glow edges may change with keying.

The marquee tag is obsolete in modern HTML standards and browsers may drop it at any time. Use a CSS animation or a generated embed snippet instead — this tool provides the embed option.

The core generator is free and works without an account: type, preview and export in your browser. Pro adds higher-resolution WebM export, premium typography and more cloud projects.
