StitchSlide

A free, no-sign-up carousel maker for Instagram, LinkedIn and TikTok. Instead of designing slide-by-slide and guessing where the crops will land, StitchSlide gives you one wide canvas — drag photos, video, text and doodles right across the seams, and it cuts the canvas into perfectly seamless slides for you. Live and public at stitchslide.com.

The brief

Carousel posts break at the swipe. Designing them slide-by-slide in a general-purpose tool means drawing your own guides, cropping each slide by hand, and hoping the seams line up once it's live on Instagram, LinkedIn or TikTok — three platforms with three different crops and no shared workflow between them.

Approach

One wide canvas instead of N separate slides. Photos, video, type and tape-style labels get designed across the dashed slide boundaries directly, and the app handles the split — the seam is the one thing the tool guarantees, so creative attention goes everywhere else.

Privacy and friction were treated as product decisions, not nice-to-haves: no account, no upload to a server, nothing to install. Projects live in the browser on the device that made them, and the same project can be picked up on a phone, finished on a laptop, and exported as PNG, MP4, or a LinkedIn-ready PDF.

Outcome
