For B2B founders, private beta

Turn your content
into clients.

Your posts bring in named leads, not likes.

Data & Scraping

Taplio, Buffer, ChatGPT, Notion, Canva. None of them talk to each other.

One tool per platform

Taplio for LinkedIn. Buffer for everything else. You copy and paste between the two.

Your writing tools live somewhere else

ChatGPT, then Notion, then Canva, then the scheduler. Your voice gets lost along the way.

Engagement isn't pipeline

50 likes, 20 comments. You don't know who they are or where they work.

Everything about your content, in one place.

From idea to conversation, without switching tools.

01

Multi-platform scheduling

Your whole week scheduled from one calendar.

02

Content workspace

Plume writes in your voice, not ChatGPT's.

03

Data & Scraping

Every bit of engagement on your posts becomes a scored lead.

Write once, publish in the right format everywhere.

Your questions, answered.

Can't find your answer? The team replies in under 4 hours.

What does Kast actually do?

Three things, in this order. It writes a post from your work, the way you write. It scores it on four points before you publish, and tells you what's off with the exact sentence in front of you. Then it publishes at the time you picked and shows you, post by post, who reacted, commented or reposted.

How is it different from ChatGPT?

ChatGPT writes a post very well. It doesn't remember how you write from one session to the next, it doesn't know the people you sell to, it will never tell you "don't publish that one", and it will never know who commented on that post. What's missing is that memory and that measurement, not the ability to write.

Does Kast publish without my approval?

Never. You review, you edit, you approve. Kast only publishes what you've approved, at the time you've chosen. An edited draft stays a draft until you click.

What about the data of the people you scrape?

Fair question: these people aren't your clients and haven't signed anything. Kast only collects what is already public on the profile of someone who engaged publicly with a post: name, job title, company. No private messages, no sensitive data, no purchased lists. Anyone can ask for their record to be deleted, and it's handled within 30 days. Your drafts are never used to train any model. If your DPO wants written answers before approving the tool, write to us and you'll get them.

Could my account get suspended?

No. Kast goes through the official LinkedIn and X APIs, with access you grant and can revoke whenever you want. No bot runs your account, we never ask for your password, and the posting pace stays within platform limits.

Will my posts sound like AI?

That's the number one risk, and the product is built against it. The score penalizes stock phrasing, and rewrites use your past posts as the style reference. You always see the before and after, and you can undo anything that doesn't sound like you in one click.

Is there a free trial?

7 days, with every feature included. We ask for a card at sign-up to stop fake accounts, but nothing is charged before day 8. To pay nothing, cancel before then: in Settings › Billing, a button opens your order page at SquidLane, our payment provider, where you confirm the cancellation.

What if it doesn't work for me?

Write to us and someone from the team will go through your case with you: your audience, your latest posts, your offer. The goal is to understand what's blocking and adjust the benchmarks to your line of work. If Kast isn't the right tool for you, we'll tell you straight instead of letting you keep paying.
