What it does

Three jobs, one screen.

Publish

Write once, choose the networks, and post now or at a scheduled time. Each network keeps its own caption, privacy setting and media rules, and you review them before anything goes out.

Measure

Views, likes, comments, shares, reach and watch time for every post you published, collected daily and lined up across networks so you can compare like with like.

Stay in control

You connect only the accounts you own or manage, you see every post before it is published, and you can disconnect an account and delete its data at any time.

How it works

Connect, write, cast.

  1. Connect an accountClick “Connect” and sign in on the network’s own page. Castfrom never sees or stores your password. The network gives us a limited token that you can revoke at any time from your account settings on that network.
  2. Write a postAdd text, images or a video. For each network you pick the audience (public, followers only, private), whether comments, duets or stitches are allowed, and whether the post promotes a brand.
  3. Cast itPublish immediately or at a scheduled time. Castfrom submits the post through each network’s official API and shows you the result, including a link to the live post.
  4. Read the numbersFrom the next day on, Castfrom pulls the metrics each network exposes for your own posts and shows them side by side. Nothing is scraped; everything comes from official APIs.
Your data

Only what the job needs.

Castfrom stores the access token for each connected account, the posts you create, and the performance metrics returned for those posts. It does not read your direct messages, your followers’ personal data, or content from accounts you have not connected.

Disconnecting an account revokes our access and deletes its stored data within 30 days. You can also ask us to delete everything at any time.

Castfrom uses the official APIs of X, TikTok, Instagram, Threads and YouTube and follows each platform’s developer policies. Use of YouTube data is subject to the YouTube Terms of Service and the Google Privacy Policy. Details are in our Privacy Policy.
