Post at the
right moment

Kairo Post writes in your voice with an AI agent, plans your campaigns and publishes to X when your audience is listening. You decide what goes out, and every action shows its credits.

From headline to posted, before breakfast

Tell Kairo Post what an account talks about. It reads the sources you chose, drafts in your voice, designs the image, schedules it for when your audience is awake and shows you what worked.

You stay in charge
of every post

Automation that asks before it acts. Nothing goes out until a person says so, and every step leaves a record you can read later.

An open model just beat every closed one on coding benchmarks.

Approval that fits your team

Owners and admins publish when they are ready. Editors' posts can wait for an admin's OK, and clients approve from a link they open without an account.

Sounds like you, not like AI

Each account gets its own voice in Brand brain: how long its sentences run, how it opens, the words it never uses. Switch voices and watch the same story rewrite itself.

Every pair under 40% similar. No copy and paste across accounts.

Campaigns

Your cap: 150 credits. It pauses before going over.

Posts go out automatically

Every post waits for a person to approve it. You also approve the plan and the cap before anything is written.

Reply faster, right inside x.com

Kairo Post Copilot is a Chrome extension. Pick an angle on any post and it drafts a reply in your voice. You press send on X yourself.

Works in Chrome, Edge, Brave and Arc on desktop.

Hot take: most onboarding emails are written for the company, not the customer. Nobody reads step 4.

Draft · 👍 Agree + add

Agree. We cut ours from 6 emails to 2 and replies doubled. The second one just asks what they came to do.

Reply on XMark as sent

Real growth, no shortcuts

No engagement farms, no tricks to get around X's limits, no posts you didn't mean to send. Just good writing, published at the right time.

Official sign in

Accounts connect through X's own sign in page. We never see your X password.

Never posts twice

If X doesn't confirm a post, we check before retrying. No accidental duplicates.

Credits you can see

Actions on X show their price before they run. AI is charged at what it really used, shown on every result.

Quiet hours

No posts in the hours you block out, and a daily cap for every account.

One switch pause

Pause all publishing and automation in a workspace with one click, and resume when you're ready.

Encrypted access

X access tokens are encrypted at rest and never shown again after you connect.

Your audience wakes up at different times. Kairo Post schedules for theirs, not yours.

Everything in one workspace

Your AI agent, content calendar, mentions and DMs, results and team, side by side. Nothing to stitch together.

Questions, answered

More in the full FAQ, or talk to us.
Is Kairo Post allowed by X?
Yes. It uses the official X API, and every account owner signs in on x.com to grant access. We don't automate likes, follows or reply rings, and anything that needs X's approval stays switched off until X grants it.
Will it post without my approval?
Not unless you say so. Nothing is published until someone on your team clicks Post now or Schedule. You can require an admin's OK for editors' posts, and clients can approve through a private link. In Campaigns every post waits for review unless an owner or admin chooses Automatically, inside a credit cap.
Which AI models does it use?
You choose, from fast, low cost models for quick edits to the most capable ones from Anthropic, OpenAI and Google, for writing and for designs. Every plan has every model, and there are no AI keys to manage.
Can my team use it?
Yes. Invite teammates as owners, admins, editors or viewers, limit people to specific accounts, and require an admin's OK before an editor's post is published. On the Agency plan each client gets its own workspace, billed to your plan.
What happens if something fails?
You get a plain explanation and a next step. If X doesn't confirm a post, Kairo Post checks what actually happened before trying again, so a post never goes out twice.

Post at the right moment.
