AddSubtitle for Web

Quick summary

AddSubtitle is a browser-based platform for translating, dubbing, and subtitling video content in more than 100 languages. It streamlines the creation of multilingual media by letting creators add and modify subtitles online, generate translated voiceovers, and adjust scripts instantly for dubbed tracks.

Primary capabilities

• Custom subtitle design: apply different color schemes and typefaces that support many writing systems.
• Online subtitle editing: import a video, place captions, and make changes directly in the web editor.
• Automated dubbing with flexible script editing: produce voiceovers that can be rewritten to fit tone or timing.
• Wide-language translation: convert on-screen text and spoken audio across a large set of target languages.
• Video rewrite with automatic lip and voice alignment: edit the on-screen script and have audio and lip movement retimed to match the new text.

Visual and text styling options

• Multiple font and color presets that suit distinct languages and aesthetic needs.
• Fine-tune spacing, size, and placement so captions remain readable across devices.
• Save and reuse custom subtitle templates for consistent branding across projects.

How the rewrite (text-edit) feature helps

AddSubtitle’s text-rewrite tool lets you change dialogue or captions after the initial recording. The platform then retimes the audio and adjusts lip synchronization so the revised script sounds natural and matches the visuals, reducing the need for costly re-shoots.

Ideal users

• Independent creators producing content for international audiences.
• Marketing teams adapting promotional videos to multiple regions.
• Educators and training departments converting material into different languages quickly.
• Small studios and businesses that need fast, low-friction localization without a full audio production pipeline.
