Beyond TikTok Captions

Add stylized captions designed to look cinematic or "YouTube documentary" style. AI-powered font selection and color matching that makes your content look professionally edited.

Two Ways to Style

Choose your fonts, let AI match colors to your video, or override with your brand colors. Full control with intelligent defaults.

AI-Powered Typography

Mosaic analyzes your video's colors and automatically selects caption styles that complement each scene. Documentary-style typography with smart positioning.

Font Selection

Choose primary and secondary fonts. Mix and match to create the perfect look for your brand.

AI Color Matching

Let Mosaic AI automatically choose colors based on each frame's color palette for perfect contrast.

Brand Color Override

Set fixed colors that match your brand identity. Perfect for maintaining consistency across all content.

Smart Positioning

AI detects faces and important visual elements to position captions where they won't obstruct content.

Intelligent Styling

Captions automatically adapt to each scene — analyzing colors, detecting faces, and positioning text for maximum readability.

Testimonials

YUDU
Co-Founder of 24/7 Artists
“When I found Mosaic, it was a game changer. I blasted it to our company, shared it with our artist community, and for the first time ever I was able to post 30+ times in a month.”

Harj Taggar
Managing Partner at Y Combinator
“The Mosaic founders are the most detail-orientated engineers I've worked with. Mosaic was voted the best product in our YC group during the Winter '25 batch. I think this will soon become the default way to edit video.”

Søren Skarsgard
Founder of EasySlice
“I reached out to Mosaic, OpusClip, Klap, and more. Mosaic was the only one that responded positively. I hopped on a call with Adish, shared the idea, and that's when I knew I found my backend.”

“Literally the best content tool out there. Don't have to waste time creating clips, editing, doing motion graphics. Need to make a video about you guys.”

Jake Blockchain

“My podcast content creation workflow has 10x'd recently and I still think I'm just scratching the surface. Getting AI to do 'something' is easy. Getting the AI to output quality — that's hard. Using Mosaic, it's pretty amazing what you're able to achieve.”
