PostMint turns your photos into ready-to-post captions. Share Sheet to posted in under a minute — so you can keep up with your life instead of your feed.
How it feels
Most caption tools want you to open an app, sign in, paste a topic, and pick a vibe. By then the moment is gone. PostMint lives in your Share Sheet — one tap, three captions, done.
Tap Share on any photo, pick PostMint, get captions. No context switching, no re-uploading, no "where did I save that one again?" — it's the shortest distance between a photo and a caption anyone has ever shipped on iPhone.
Pick Instagram, TikTok, X, Facebook, or LinkedIn. PostMint knows each platform's vibe and tunes captions — hashtags on IG, zero hashtags on LinkedIn, punchy hook on TikTok.
first bowl of the season and yes, I'm emotional about it.
A 90-second onboarding captures your topics, tone, and goals. Every caption after that sounds like you on a good day — warm, weird, confident, whatever you picked.
“The season's first bowl hit different. 10/10 would cry again.”
Your photo goes to our AI provider for a single request, then it's gone. Never stored, never used for training, never linked to your Apple ID. There's no PostMint account because there's no PostMint server — just your phone and a one-shot API call.
Pricing
No free trial. No credit card to start. If you decide three captions per month isn't enough, upgrade. If not, keep using the free tier as long as you like.
Subscriptions auto-renew until cancelled. Cancel anytime from Settings → Apple ID → Subscriptions. No refunds for partial billing periods — standard Apple App Store terms apply.
Required by Apple · Explained like a human
We have to disclose this — Apple guideline 5.1.2(i) says so — but we'd tell you anyway. In plain English, here's the whole deal.
Read the full privacy policy →When you tap Generate, your photo is sent to AIML API for one request. That's it. Nothing queued, nothing cached, nothing kept.
Your photo isn't used to train any AI model — not AIML's, not OpenAI's, not ours. We pay for a provider that explicitly doesn't train on inputs.
We never send your Apple ID, name, or email. The request is anonymous from AIML's side. We don't have a server that would log it even if we wanted to.
You'll see a consent screen before your first generation. You can turn AI features off later in Settings — though without them, PostMint can't generate captions, which is most of the app.
Provider: aimlapi.com/privacy — an OpenAI-compatible AI API provider.
