What platforms are supported?
Twitter/X, LinkedIn, Facebook, Instagram, and Threads. We're adding more platforms regularly based on user demand.
Can I upload photos?
Yes! Pro users can attach images to their posts. Each platform will receive the same image alongside your text.
Is there a free trial?
Better — it's completely free right now during our beta! You get unlimited posts to all 5 platforms. We handle copying your text and opening the apps, you just paste and post.
When is auto-posting coming?
