Posts you can share as images

Lanai’s headline differentiator is small enough to fit in a sentence: long-press any post, choose share as image, and Lanai will render it as a magazine-quality picture you can send anywhere.

It is also the part of the app that does the most work on your behalf. Behind that sentence is a rendering pipeline that detects how dense the post is, picks the right text size and image layout for the canvas, runs Vision-based face and subject detection on the photographs to keep them in frame, and assembles a final image at 3× scale that holds up at any zoom.

Seven templates

Each one is its own visual personality — same post, seven different ways to dress it. Pick the one that fits the mood of what you’re sharing, or let Lanai default to the one that suits your theme.

Three sizes

Square (1080 × 1080) for Instagram and Threads. Portrait (1080 × 1350) for the in-feed shape that travels well across platforms. Story (1080 × 1920) for the full-screen vertical surfaces that Stories and short-video apps prefer. All three render at 3× scale, so they stay crisp on any display.

Smart cropping that keeps faces in frame

When a post has images, Lanai runs face detection and attention-saliency analysis on each one. The result is a nine-position alignment grid that tells the template renderer where the visual focus actually is — so a portrait photo gets cropped around the face, not around the centroid of the picture. Screenshots and text-heavy images are recognized for what they are and rendered with fit instead of fill, so nothing important leaves the frame.

Toggles you can use without thinking

Above the preview, a quiet bar of options lets you turn the post’s images on or off, show or hide the date, include the link preview, include a quoted post, and toggle the watermark. Each toggle is context-aware — the link preview only shows when there is a link to preview; the quote toggle only appears when there is a quoted post.

The watermark

The bottom-right corner carries a small Lanai watermark at 40% opacity. It is on by default, and it is removable. The reason it’s on by default is plain: every shared image is also, gently, an invitation. The reason it’s removable is the same one: if the moment is yours alone, the moment is yours alone.

This is the part of the app most likely to surprise you. People who don’t think of themselves as designers find that something they wrote on a Tuesday morning looks like an editorial pull-quote when it lands in their camera roll. That is the design intent. The typography knew how to do that. Lanai just gave it a frame.
