For knowledge professionals

Your audience doesn't need more emails. It needs you to keep showing up.

Kai News is the newsletter platform with a Continuity Engine: AI that writes in your voice, a radar that notices when your list is cooling down, and proactive nudges with ready-to-edit ideas — before silence turns into distance.

Free plan forever · No credit card · Real AI included

Sound familiar?

If you write to an audience — a newsletter, your clients, your community — you know these moments.

01

The blank Tuesday

You know you should write this week. You open the editor and the question lands: what do I say that's actually worth their time?

02

The weeks that slip away

One busy week becomes three. Nobody complains, nothing breaks — and that's exactly why it keeps slipping.

03

The awkward comeback

The longer the silence, the heavier the return. Do I apologize? Do I pretend nothing happened? Easier to postpone it again.

04

AI that sounds like everyone

You tried ChatGPT. The result was correct, polished… and interchangeable with anyone else's newsletter. Your readers can tell.

None of this feels urgent. That's the trap: a list never complains when you disappear — it just quietly stops opening, stops trusting, stops being yours. The audience you worked so hard to build cools down in silence.

We built Kai News on one conviction

The real arena isn't email marketing. It's the relationship of trust between you and the people who chose to hear from you.

Your audience is an asset that belongs to YOU — not to an algorithm that decides who sees you today.

And the real competitor isn't another tool. It's “this week I didn't get around to writing”.

Everything in Kai News exists to keep that relationship alive. The rest is plumbing.

The Continuity Engine

Other platforms wait for you to log in. Kai News keeps watch over the relationship — and comes to you.

You always know where you stand

A radar over the relationship

Set your rhythm — weekly, biweekly, monthly. The radar tracks how long your list has gone without hearing from you: healthy, at risk or cold. What's cooling becomes visible before it becomes distance.

The proactive nudge

Kai writes to you first

When you cross into “at risk”, Kai emails YOU: a short, guilt-free note with 1–3 ideas anchored in your topics and in what your audience responded to. One click turns an idea into a draft.

Ideas + research

A good reason to write, every week

Ideas from your pillars, sequels to what performed best, and deep research on your field with cited sources — so you write because you have something to say, not to fill a slot.

Even after months of silence

Momentum — and a way back

Streaks measured in months of active relationship (not childish badges), and a Return mode with three honest ways to reappear after a pause. No guilt: coming back is one click.

The radar and the nudges cost you nothing — they're not a premium add-on. They're the reason Kai News exists.

AI that lowers the friction — without replacing your voice

The point isn't that a machine writes your newsletter. It's that publishing in YOUR voice stops costing you a whole evening.

It learns who you are, by chatting

You train your “essence” in a conversation: your topics, your stances, how you write, who you write to. Paste old articles or attach files — Kai distills your profile and discards the raw material. It's never stored.

Every button writes like you

Subject lines with their rationale, A/B variants, rewriting a block, or a full campaign from a one-line brief — always through your essence: your tone, your do's and don'ts.

You always have the last word

The AI proposes; you edit and approve. Nothing goes out on its own. And it never invents facts or credentials — if something's missing, it leaves a [pending] marker instead of making it up.

Simple economics: KaiCoins

Every AI action has a flat, visible price in KaiCoins. No token math, no surprises. Sending emails never costs coins — you only spend when the AI works for you.

The best week to write to your list was last week. The second best is this one.

The questions you're probably asking yourself

Straight answers — the same ones we'd give you over a coffee.

What is Kai News?

Kai News is a newsletter and email marketing platform built for knowledge professionals — consultants, advisors, educators, experts — whose real challenge isn't sending emails but sustaining the relationship with their audience. It combines the usual tools (subscribers, campaigns, forms, analytics) with a Continuity Engine: AI that writes in your voice, a radar that detects when your list is cooling down, proactive idea nudges, deep research with cited sources and a guilt-free Return mode.

How is it different from Mailchimp, Substack or beehiiv?

Those platforms optimize the sending or the growth; Kai News optimizes the continuity of the relationship. What makes it different: a radar that measures how long your audience has gone without hearing from you, nudge emails that arrive with ready-to-edit ideas when you're cooling down, AI trained on your essence so drafts sound like you (not like everyone), and field research with cited sources. And you still get all the standard tools — editor, forms, A/B testing, analytics, API.

How much time does this actually take each week?

Less than it costs you today. With your essence trained, a complete draft from a one-line brief takes minutes; polishing a block or a subject line is one click; and when you don't know what to write, the assistant or the nudge brings you 1–3 anchored ideas. The honest answer for most weeks: 20–30 minutes to review, adjust and send.

Will the AI sound like me — or like every AI newsletter out there?

It's designed to sound like you. You train your essence in a conversation (topics, stances, tone, phrases you use and avoid) and every AI action injects that profile. You review and approve everything before it goes out. And if you haven't trained it yet, everything still works — just more generic until you do.

I haven't written to my list in months. Is it too late?

No — this is exactly what Return mode is for. It gives you three honest ways to reappear (a reflection, a useful resource or a brief update), written in your voice, without over-apologizing. Audiences forgive silence more than you think; what erodes them is disappearing forever. And once you're back, the radar helps you not fall into the same hole.

Will my emails end up in spam?

We do everything by the book so they don't: SPF and DKIM authentication, one-click unsubscribe (Gmail and Yahoo standard), double opt-in on forms, and automatic suppression of bounces and complaints. No platform can honestly promise 100% inbox placement — but the technical side is covered, and the anti-spam policy protects the sending reputation every account shares.

Is my list really mine? Can I leave whenever I want?

Yes and yes. Your subscribers export to CSV in one click, custom fields included. There's no lock-in and no retention tricks. Your account's data is isolated from every other account's, and if you cancel a paid plan you never lose data — you just can't exceed the free plan's limits until you upgrade again.

What happens to the material I paste to train the AI?

It's interpreted and discarded. Kai distills a structured profile (your voice, pillars, audience) and stores only that — never the raw articles, emails or files you shared. AI usage logs store numbers (tokens, cost), not content.

What are KaiCoins? Do I pay per subscriber or per email sent?

KaiCoins measure one thing only: how much AI you use. Every action has a flat price (suggesting subject lines: 20, a full campaign: 240) — visible before you click, with no token math. It's the KaiCoin standard across the whole Kai family (1 coin ≈ US$0.001 of real AI). Contacts and emails are your plan's limits, and sending never consumes coins. Every plan includes a monthly allowance, and you can top up anytime.

Is the free plan actually free, or a trial in disguise?

Free forever, no card required: 300 contacts, 1,000 emails a month and 1,200 monthly KaiCoins — enough for about 2 campaigns fully written by AI, plus your first deep research as a welcome gift. When your audience or your AI use grows, plans start at US$9/month.

Can I bring my current list?

Yes — import a CSV and map your columns to fields (including custom ones). The one condition is real: only people who gave you their consent. It protects your deliverability and everyone else's on the platform.

I'm in Latin America — how do I pay?

Prices are in USD as a reference and you pay in your local currency. Card subscriptions renew automatically; if you don't use cards, you can pay one month or a full year (2 months free) as a one-time payment with local methods like PSE or Nequi via dLocal Go.

What is the Kai Bridge with Kai Career Elevate?

An optional link between your Kai News and Kai Career Elevate accounts (same email) — Career is our professional growth system. Linked: your career assets (posts, narrative, market findings) arrive here as ready-to-write campaigns, every campaign you publish goes back as visibility evidence, and you get +10% monthly KaiCoins in both products. There are also joint bundles (Kai Impulso Total and Kai Autoridad) cheaper than buying separately. Each product is complete on its own; the bridge connects and disconnects with one click.

Your audience is still there.

The relationship picks back up with a single email. And you don't have to write it alone.
