Run social media for every client without hiring.
Castiva's AI writes and designs each client's posts in their own voice, then schedules and publishes to Facebook, Instagram, TikTok and X.
From “we need a post” to posted
Teach it each client
Tone of voice, banned topics, brand colors, hashtag sets. Once per client, and every post after that respects them.
Say what the post is about
One line of brief. Castiva writes the caption and generates the image in that client's voice, tuned for each platform.
Approve and publish
Send it for review or pick a time. It goes out to your client's accounts, and the numbers come back.
Everything else you need to run ten clients at once
Every client gets a voice
Store the tone, the banned topics, the colors and the hashtag sets once. Every caption and image after that respects them, so a restaurant never sounds like a law firm.
Approvals, built in
Queue posts for review — nothing goes live until it’s approved, and every decision stays on the record.
A calendar you'll actually enjoy
Drag, drop, done. Batch your whole week and Castiva shows the best posting times per network.
