Pick a slide type, then type your words in the boxes.
Set colors, your @handle, and an optional logo.
Add more slides, or paste a long note into Auto-Split.
Click Export PDF. Save a deck if you want to come back later.
Full Guide
How each part works. Still ELI10. Still local-only.
Pick a platform
In the left column, tap LinkedIn, Instagram, TikTok, Pinterest, X, Facebook, or Threads.
Zumble picks the usual size. The buttons just above the preview show only the sizes that app accepts. Tap one to override.
Use templates
Open Template Store.
Each card shows the slide design. Tap Use this template to put it on the slide you are looking at. Pro cards are marked.
Yours is for cards you save. Type a name, then tap Save current slide.
Edit text and brand
Open Content Wizard. Pick a layout. Type in the boxes. The preview updates as you type.
Open Brand for colors, fonts, @handle, logo, and background. Those show on every slide.
Caption and hashtags
Under Platform, you can add an optional caption and hashtags. They save with the deck. They are not drawn on the slides — they are the words you paste when you post.
Generate Caption and Generate Hashtags are Pro. They draft text from this deck. Edit before you post. Limits still apply.
Limits follow the app you picked. Instagram allows up to 30 hashtags. TikTok allows 5. X is short (280 characters, 2 tags). The counter under each box shows how much room you have left.
Use Auto-Split
Open Auto-Split. Paste a long note.
Paragraphs become cards. Lists become checklists. Tap Generate slides.
Turn off “Replace existing slides” if you want to keep what you already have.
