Automatic subtitles that hold attention

On mobile, most videos are watched without sound. Without readable subtitles, your message is lost before the first sentence ends. On TrendStory, subtitles are generated and styled automatically, with no extra step.

Many people watch TikTok, Reels or Shorts with the sound off — on public transport, at work, in public spaces. A video without subtitles loses a large part of its audience within the first few seconds.

TrendStory generates subtitles automatically on every video it creates: precise sync with the voice, word-by-word or sentence-by-sentence breakdown, and an animated style of your choice — karaoke, simple or italic. There's nothing to adjust manually, everything comes out ready.

Worth knowing: TrendStory subtitles the videos it generates itself, from script to assembly. It's not a tool where you upload an existing video to subtitle it afterward.

What TrendStory does for you

Automatic sync

Subtitles precisely follow the generated voice, with no manual timing fixes needed.

Several animated styles

Word-by-word karaoke, simple, or italic — each style is designed to catch the eye on mobile.

Fonts adapted per language

Devanagari for Hindi, Naskh for Arabic: every language gets readable subtitles, never broken characters.

7 languages available

English, French, Spanish, German, Hindi, Arabic and Portuguese, for both voice and subtitles.

No manual setup

No timing to adjust, no font to pick one by one: the style applies to the whole video in one click.

Built into the full pipeline

Subtitles arrive alongside the script, animation and music — one single creation, not a separate step.

A useful clarification

TrendStory subtitles the videos it generates itself: script, images, animation, subtitles and music all come out of one creation. It's not an upload tool where you drop in an already-filmed video to subtitle it afterward.

If what you need is exactly that — a complete video, story, characters, subtitles included — starting from a simple idea, that's exactly what TrendStory does, with no extra step for you to manage.

Frequently asked questions

Can I upload my own video to add subtitles?
No. TrendStory only subtitles the videos it generates itself, as part of its full creation process (script, images, animation). It's not an upload-to-subtitle tool for footage you already filmed.
What subtitle styles are available?
Three animated styles: karaoke (word by word, in rhythm with the voice), simple, and italic. The style is picked once and applies to the whole video.
Do subtitles work in multiple languages?
Yes, across TrendStory's 7 languages — English, French, Spanish, German, Hindi, Arabic and Portuguese — with fonts adapted to each script, including Devanagari and Arabic.
Do I need to set the sync manually?
No. Subtitles are generated already synced with the video’s voice, with nothing to adjust on your end.
Do subtitles cost extra?
Subtitles are part of TrendStory's video creation pipeline, included in your monthly subscription credits. Plan details are on the Pricing page.
Is this suited for TikTok and Instagram Reels?
Yes, that’s exactly the main use case: videos come out in vertical 9:16 with subtitles designed to be read without sound, on mobile.
