Platform-Aware Layout
It knows where TikTok's UI covers your video
A 9:16 canvas isn't one thing. TikTok, Reels, and Shorts each cover a different part of it with their own UI, and a caption placed 400px from the bottom is safe on one and buried on another. ReelM carries measured insets for all of them and checks your layout against the one you're actually publishing to.

[How it works]
Platform-Aware Layout in three moves
Declare the destination
Pick a platform and ReelM sets the canvas, the frame rate, and the safe-area insets together — never inferred from aspect ratio alone.
Place by region
Drop items into named regions — title, subtitle, caption, lower-third, safe — instead of guessing pixel coordinates.
Run the linter
Eight rules flag text under the platform UI, off-canvas items, overflowing or tiny text, overlaps, and crowded edges — with an auto-fix pass.
[Under the hood]
Built to be used, not just demoed
The details that separate a party trick from a tool you reach for daily.
Measured, not guessed
Each platform spec is tagged as measured or approximate, so the app is honest about what it actually knows.
Live preview chrome
Overlay the real TikTok, Instagram, or YouTube interface on the canvas while you work. It's a guide — it never renders into the output.
Broadcast safe zones
Title-safe and action-safe percentages are tracked separately from platform insets, because they answer different questions.
Align, distribute, stack
Real layout operations — align to an edge or centre, distribute with an even gap, stack in a direction with an anchor and alignment.
Text measurement
Ask for the rendered size of a string at a given font, size, weight, and max width before you place it. No trial and error.
Auto-fix
The linter can run in fix mode and move offending items back inside the safe area, one undoable batch.

Ask for it instead of clicking it
The linter is also ReelMy's quality gate — it can't call a plan complete while layout errors remain.

Platform-Aware Layout, answered
Because 9:16 is TikTok, Reels, and Shorts at once, and their UI covers different bands. ReelM asks instead of guessing.
Never. It's a canvas guide only — the render pipeline doesn't know it exists.
Regions are derived from the active platform's safe area, so changing platform re-derives all eleven for you.
