1. PinBoostr
Best free optionFree in beta · Every account
PinBoostr publishes to LinkedIn through the official API with a single posting permission and no browser extension. You write by hand or draft with AI in your own voice, design carousel decks in a built-in studio, and schedule everything into posting-time slots on a calendar. It is the only tool here that also runs a full Pinterest engine from the same dashboard.
Best for: Creators and small teams who want scheduling, carousels and AI drafting without a browser extension touching their account — and anyone already publishing to Pinterest.
