PostFlow is your all-in-one app for composing smarter social posts, organizing your hashtags, and listing items across Reddit, eBay, and Shopify — all from one place. Whether you're firing off a quick post or cross-listing an item everywhere it needs to go, PostFlow keeps you fast and organized. AI-POWERED COMPOSING Set your instructions once — they persist across sessions — and let the built-in AI write your post and hashtags for you, tuned to your voice and your limits. Don't love the result? Undo and tweak your instructions in a single tap. HASHTAG GROUPS, DONE RIGHT • Save reusable Hashtag Groups and import them with one tap. • Extract hashtags automatically from any block of text. • Automatic duplicate removal so you never double up. • Set your own prefix, per-post hashtag limit, and a custom separator between your text and your tags. • Preview the finished post, then copy it — ready to paste anywhere. POST HISTORY THAT WORKS FOR YOU Every post you share is saved, so you can re-import its text or hashtags later. Search your history and pin the posts you want to keep forever. REDDIT POSTING & LISTING MANAGEMENT Switch into Reddit mode to draft, organize, and publish straight to the subreddits you choose: • Secure Reddit sign-in. • Rich drafts: title, body, auto-comment, flair, SKU, private notes, and reorderable images with pinch-to-zoom previews. • Per-subreddit rules for repost cooldowns and verification windows. • Smart sorting into Eligible to Repost, Verification Not Cleared, Ineligible, and Posting — so you always know what's ready. • Live submission progress, one-tap bump, archive/unarchive, and duplicate-to-relist. • Verification photo tracking with timestamping and hosted images — get warned before your proof photos lapse. • Full submission history with direct links to your live posts. ONE ITEM, EVERY PLATFORM Paste a listing and let the app do the heavy lifting: • Auto-parse 20+ details and generate polished titles and descriptions with AI. • Pre-fill a Reddit draft, a Shopify product (with structured product data and images), and an eBay listing — in a single flow. • Connect multiple eBay accounts and publish live listings with automatic image upload and fee-aware pricing. • Filter your listings by platform to see exactly where each item lives. BUILT TO FIT YOUR WORKFLOW • Secure syncing with your personal iCloud account, across all your devices. • Looks great in both Dark and Light mode. • Your API keys are stored safely in the device Keychain. Compose faster, stay organized, and publish everywhere with PostFlow.
