Your social media manager lives in WhatsApp.
Every week, Coso drafts your posts and sends them straight to WhatsApp. Approve what you like, edit what you don't, or send a photo back and watch it become a post. No new app, no dashboard to remember.
Free to start, 3-minute setup
It doesn't wait for you to ask.
Most AI tools need a prompt every time. Coso already has your week ready before you've opened WhatsApp.
ChatGPT: Asks what you'd like it to write. Then asks again next week.
Writes it first. Your week of captions is ready before you've opened the app.
A general chatbot: Sits there until you message it. Nothing happens on its own.
Messages you. Sends the finished posts to WhatsApp, unprompted, every week.
Your camera roll: Photos sit there until someone remembers to post them.
Turns it into a post. Send it on WhatsApp and get a caption and schedule back.
Tell Coso what happened. It handles the rest.
A photo and a few words is all it takes to turn today into a post.
Send a photo or a note
Snap what's happening today and send it straight to WhatsApp, a line of text or none at all.
Coso works out the context
It reads the photo, checks your brand, and figures out what the post should say.
A caption comes back
Written in your voice, sized for whichever platform it's going out on.
You approve from the same chat
Say yes, ask for a change, or leave it. Nothing publishes without you.

One conversation. Your whole week sorted.
Showing up every week is the hard part. Coso does that for you, from a chat you already check.
Every week, without a reminder
- Coso drafts the week's posts on its own schedule.
- You find them waiting in WhatsApp, not on a to-do list.
Built around real moments
- Send a photo, a voice note, or a quick line about your day.
- Coso works out what to make of it and drafts the post.
Nothing goes out without you
- Every post waits for your approval in the same chat.
- Ask for a change and Coso redoes it on the spot.
One thread, every platform
- Facebook, Instagram, LinkedIn and X from one conversation.
- No extra logins, no separate app to check.
This isn't a chatbot you have to manage.
Coso works on its own schedule and only messages you when there's something to approve, or when you've sent it something to react to. You're not maintaining a conversation. You're glancing at one.

Frequently asked questions
Can I manage my social media through WhatsApp?
Yes. Coso sends your week of posts to WhatsApp for review. Approve, edit, or ask for changes without opening another app.
Do I have to prompt Coso every week?
No. Coso drafts your posts on its own schedule and sends them to you. You only need to react, not request.
Can I send Coso a photo?
Yes. Send a photo on WhatsApp with a line about what's happening, and Coso turns it into a caption and schedules it for the right platform.
What about voice notes?
Send a voice note describing what happened and Coso turns it into a post, the same way it does with a photo.
Which platforms can Coso post to from WhatsApp?
Facebook, Instagram, LinkedIn and X. One conversation covers all four.
What if I don't reply?
Nothing publishes without your approval. Coso holds the draft until you respond, however long that takes.
How much does it cost?
Coso Core is $149 a month. Coso Managed, where we run the whole thing for you, is $699 a month. A typical agency doing the same job charges $3,000 or more.
