Why creators pick Fliki for subtitles
Subtitles that actually look good, in 80+ languages
Standalone subtitle tools transcribe and stop. Fliki ships subtitles inside a full video editor with animated styles, translations, and an integrated voice pipeline.
Word-level timing for TikTok-style animations
Captions are generated at word level (not just sentence level), so animated styles like bouncy, word-pop, and karaoke highlights actually sync to speech.
Automatic speaker labels for multi-speaker content
Interviews, podcasts, panels, and group video calls get per-speaker labels automatically via our audio to text engine. Each line carries the speaker name in both the burnt-in caption track and the exported SRT. No manual tagging.
Course-platform integrations: Moodle, Canvas, Thinkific (coming soon)
Direct SRT and VTT export compatible with Moodle, Canvas, Thinkific, Kajabi, and Teachable. Multi-language SRT bundles for international cohorts, chapter-marker support, and WCAG-compliant caption styling for accredited programs.
WCAG-compliant captions for enterprise and government
Customizable contrast ratios, font sizes, and caption positioning to meet ADA Section 508 and EU Web Accessibility Directive requirements. Export-ready SRT and VTT for SCORM and xAPI learning management imports.
80+ language transcription
Transcribe in 80+ languages with native-language accuracy. Spanish, French, German, Hindi, Mandarin, Arabic, Portuguese, Japanese, Korean, Russian - and most regional dialects.
One-click translation in 80+ languages
Generate captions in the source language, then auto-translate into 80+ languages with one click. Pair with Fliki AI voiceover for matching localized audio.
Animated caption styles in one click
Pick from a library of TikTok, Reels, and YouTube short caption styles - bouncy, word-pop, karaoke, highlight, classic. Every style is editable down to font, color, and per-word emphasis.
SRT, VTT, or burnt-in - your call
Export as a separate SRT or VTT file for YouTube and platform uploads, burn captions directly into the video for social, or both at once. Same project, multiple deliverables.
Brand-kit consistent captions
Set custom fonts, colors, stroke, drop shadow, and animation speed, then save the look as a brand preset that applies across every future project.
Edit captions like you edit text
Wrong word? Click and retype. Need to merge two lines? Drag. Change the timing? Slide. The same editor handles transcription edits, animated style, and final video export.
Voice + captions in one project
Skip the import/export dance. Generate the AI voiceover and captions in the same project so timing always matches and re-renders update both tracks.
