Postlia

Postlia is a social media scheduler that lets you write a post once and publish it everywhere you post: LinkedIn, Instagram, TikTok, Bluesky and more.

The idea is simple. One composer, every network. Write your post, adjust the caption per platform if you want (a LinkedIn post and a TikTok caption shouldn't read the same), pick your accounts, and publish now or schedule. A calendar and posting queue handle the rest of your week: set your preferred time slots once, and new posts fall into the next free slot automatically.

A few things it does differently:

First Draft. Postlia can plan your posting week from your own material. It reads your ideas, your past posts and the feeds you follow, then drafts every post in your voice. Each one lands in Drafts as exactly that: a first draft, yours to sharpen, approve, or kill. Nothing publishes until you say so.

AI Slop Detector. Feeds are drowning in machine-sounding text, so Postlia includes a tool that scores how AI-generated your writing sounds before you hit publish. Between this and First Draft, the position on AI is consistent: it should sharpen your voice, not replace it.

Honest delivery receipts. When a platform rejects your post (wrong video format, expired token, rate limit), most tools fail silently. Postlia shows exactly what the platform said and what to do about it, and emails you when something needs your attention.

Alongside the scheduler there are 25+ free tools that don't require an account: username and handle checkers for every major platform, bio generators, image size references, and a best-time-to-post hub with per-platform, per-day data.

Postlia comes with a 7-day free trial, then $29/mo for creators or $49/mo for Pro (First Draft is part of Pro). Built and run by two independent founders.
