Kai, your AI X (Twitter) agent
Posting on X every week is easy to plan and hard to keep up. Kai is Toby’s AI Twitter agent: he writes posts and threads with a clear hook, real numbers and your founder voice, turns your best articles into threads, and publishes them on X through the API once you approve. He works from your Brand Brain, so a post about your product sounds like you, not like a generic growth account.

What Kai does
Writes posts and threads in your voice
Kai reads the brand voice and content strategy documents of your Brand Brain, plus Toby’s memory of your past edits and preferences. One idea per post, a first line that earns the second, concrete numbers instead of adjectives, and no wall of hashtags.
Recycles your winners
Your best blog post or LinkedIn post of the week rarely gets a second life. Kai turns it into a native X thread: the key insight up front, one point per post, a last post that sends people to the full piece. When a published post clearly outperforms the others, Toby can suggest recycling it on other channels.
Publishes through the X API, after approval
X is a ready connector: you add your own X developer app keys and Kai can publish approved posts and threads, each post replying to the previous one. You can publish right away or schedule it in the Calendar, and it goes out at that time. The X API is paid per use, billed by X.
Uses real numbers, never invented ones
Founder posts work when they are specific: what you shipped, what it cost, what you learned. Kai uses figures from your connected tools or from what you tell him. When he has no number, he writes the post without one or asks you, rather than making one up.
Drafts replies to conversations you bring
Paste a post from your niche that you want to reply to, and Kai drafts a reply that adds something: a data point, a counter-example, a short story. Through the connector he can publish and check the connected account; he does not read your timeline or mentions today, so you choose the conversations.
Optional Autopilot for X
If you turn Autopilot on for Kai and for the company, posting on X becomes one of the few safe actions he may run without asking. It is off by default, and the Pause button stops everything at once.

Three hooks for the same announcement

A week on X, planned
The playbooks
- 1
Recycle a winner
Turn the best blog post or LinkedIn post of the week into a native thread instead of writing from scratch. Ideas that win once tend to win again in another format.
- 2
Hook first
The first line decides whether anyone reads the second. Kai often proposes two or three hooks for the same post so you pick the one that sounds most like you.
- 3
One idea, concrete numbers
One post, one idea. Numbers, names of tools, a before and after. Adjectives and vague claims get cut, and hashtags are used sparingly or not at all.
- 4
Founder voice
First person, real decisions, real mistakes. Kai draws on the Brand Brain, your connected data and the customer quotes your meeting notetaker brings into memory, so posts come from your business, not from templates.
How approval works
By default every post and thread is a draft. Nothing reaches X until you approve it and click “Publish now” or schedule it.
Approved threads are published in order, each post as a reply to the previous one, so the thread stays together.
Autopilot needs two switches: Kai on Autopilot and the company on Autopilot. Only then can he post on X without asking, within your daily AI cost cap. The Pause button stops it instantly.
Without X keys, posts stay drafts: copy them, post them yourself, then click “Mark as published”.
Tools Kai works with
X connects with your own developer app keys (Read and Write permission), with no app review needed for your own account. The X API is billed by X per use. Posts are text only today, up to 280 characters each.

Frequently asked questions
Can Kai post on X automatically?
Only if you choose so. By default he asks before publishing. If you put both Kai and the company on Autopilot, posting on X is one of the few actions allowed to run alone, alongside drafts in your CMS or Gmail. Ads and anything that spends money are never automatic.
Do I need to pay for the X API?
Yes. X charges for API access per use, and Toby uses your own developer app, so the usage is billed by X to you. You create the app on X’s developer site, give it Read and Write permission and paste the four keys into Toby. Check X’s current pricing before you start.
Will the posts sound like a bot?
Kai writes from your Brand Brain’s brand voice and from Toby’s memory, which keeps your edits and stated preferences, so drafts get closer to your style over time. Still, read before approving: an AI can be wrong or flat, and you know your voice better than any model.
Can Kai reply to my mentions or grow my followers?
He does not read your mentions or timeline today: the connector publishes and checks the connected account. You can paste any post and get a reply draft. Kai does not buy followers, run follow/unfollow tactics or automate likes; growth comes from posts worth reading.
Can Kai post images or videos on X?
Not through the API today: publishing covers text posts and threads. If a post needs an image or a screen recording, Kai says so in the draft and you can add it when posting manually.
How is Kai different from a scheduling tool?
A scheduler posts what you wrote. Kai writes it: from your articles, your customer calls and your numbers, in your voice, with hooks you can choose from. Approved posts can then be scheduled in Toby’s Calendar and published at that time.
