Frequently asked questions

Everything you need to know before you begin.

Is Sizth only a social scheduler?

Today, yes—Sizth Studio is our first product. Sizth is a software company building multiple productivity tools; new products are under active development.

What platforms are supported?

Instagram, Facebook, TikTok, X/Twitter, LinkedIn, YouTube, and more. We continue to add destinations and regional variants.

How does scheduling work?

Create your custom posting windows once. Drop content in and Studio auto‑routes it to the right channels at the right times. Override any post with a click.

Is our data secure?

Data is encrypted at rest and in transit. We support SSO/SCIM and granular role‑based permissions. SOC2 is in progress.

Create once. Let Studio handle the rest.
