How Karrow learns your voice

What does Karrow read to learn my voice?

Each time Karrow drafts, it reads the issue you picked, your publication’s five most recent other issues, and the last three posts you published from that publication on the platform it’s writing for. That way new drafts sound like you do now.

It reads up to the first 7,000 characters of the issue you picked, and a shorter sample of about 1,800 characters from each past issue and past post. That’s plenty to pick up how you open, how long your sentences run, and the words you reach for.

On top of that it adds your written rules for the channel, and the notes it has learned from how you edit. Your published posts matter most for a channel, because they show how you actually write there, not just how you write long-form.

Does Karrow copy other people’s posts?

No. Karrow only learns your voice from your own publication. It never borrows wording from other people’s posts, and each of your publications keeps a voice of its own.

Playbooks are the one place other accounts come in, and they only carry structure: a numbered list, a hook followed by a payoff, a thread that builds to a point. The words are always written from your issue, in your voice.

It learns from what you keep

When you schedule an AI draft as it is, Karrow takes that as a yes. When you edit a draft and then schedule it, Karrow learns from the difference. When you delete an option or regenerate, it learns what you didn’t want.

After every three of these on a channel, Karrow looks back over your 20 most recent ones and writes a few short notes about patterns that keep coming up, such as cutting hedging words or shortening the opening line. A single edit is never enough to make a note.

Learning happens per publication and per platform, so what you like on LinkedIn doesn’t change your X posts.

Edits teach Karrow when you schedule the post. A draft you edit and leave unscheduled doesn’t count yet.

Do my teammates’ edits change my drafts?

No. Learned tone is kept per person: the notes Karrow learns from your edits are yours, and a teammate’s edits build their own notes, even on the same publication. A batch uses the notes of whoever started it.

Written rules are different: they belong to the publication, so a rule anyone saves in the Voice tab applies to everyone’s drafts for that publication.

Add your own rules

For things you always want, write them down. Open the publication, go to its Voice tab, and type a rule for any channel, for example “no rhetorical questions” or “never open with a stat”. Click Save. Your rules apply to every future draft and always win over anything Karrow has learned.

Leave a channel blank for no extra rules. Short, specific rules work best: “keep it under three sentences” is easier to follow than “be punchy”. Rules only change future drafts, not ones you already have.

Do the AI edit buttons use my voice?

Partly: the edit buttons work only on the text you selected, so they reshape wording that’s already yours, but they don’t reread your issues or your Voice tab rules.

Select up to 2,000 characters in a draft and pick Shorten, Add hook, Punch it up, or Fix grammar, or type your own change. Karrow also tells the edit the platform’s character limit, so Shorten aims to fit it. The new text replaces your selection in place; press undo (⌘Z or Ctrl+Z) if you don’t like it.

An edit made this way counts like any other edit once you schedule the post, so it still teaches Karrow your taste. The free plan allows 60 AI edits a day and Pro allows 600.

Why do my drafts still sound generic?

Usually because Karrow has little of your own writing to go on yet. A new publication with only a few short issues, or a channel you haven’t posted to through Karrow, gives it less to learn from.

Three things help. Publish a few posts on that channel, because your own published posts are the strongest example Karrow has. Add a rule for the thing that bothers you most. And keep editing and scheduling: after a few rounds on a channel, Karrow starts writing notes about how you like it.

Start over if you need to

If your style has changed, use Reset learned tone in the Voice tab. It clears what Karrow picked up from your past edits on that publication. Your written rules stay as they are.

Reset only clears your own learned tone, on every channel of that publication. Teammates keep theirs, and Karrow starts relearning yours as soon as you schedule or discard drafts again.

Playbooks don’t change your voice

A playbook only shapes a post’s structure, like a numbered list. The words are still yours.

If you don’t pick one, Karrow chooses from the formats doing well on that platform. On Pro you can bookmark playbooks and pick them under Use a saved playbook (optional) when you draft, to steer the structure without touching the voice.
