AI NEWSLETTERS, COMPARED

Which AI Newsletter Fits Your Business?

By Sam Woods, editor of Bionic Business. Facts checked 9 November 2026.

If you run an online business, you probably get more AI newsletters than you have time to read, and sooner or later you decide which ones to keep. I write one of them, so I'm not a neutral judge. The useful thing I can do is tell you who each of the others is for, and when one of them is a better pick than mine.

I read all five of the others, and I've been a paying subscriber to two of them, Every and Lenny's. What I say about them comes from their own websites, which I read on 9 November 2026. Prices change, so check theirs before you pay for anything.

Six Newsletters At A Glance

Prices and descriptions from each publication's own site, read 9 November 2026.

Every: AI Ideas, Apps And Training For Teams

Every is the nearest thing to Bionic Business on this list: a paid publication about using AI at work, by what it calls "practitioners who build with AI daily." It publishes essays and columns, reviews new models as they come out in a column called Vibe Check, and builds its own AI apps:

Every Agent, an AI agent in Slack that a whole company can use.

Monologue, for voice dictation.

Compound Engineering, a set of Skills for coding agents.

Every also sells AI training to companies. A subscription costs $30 a month, or $288 a year with a 14-day free trial, and there's a free tier with limited access.

Pick Every if you want one subscription for AI ideas, apps and model reviews, which is the promise in its own tagline: "the only subscription you need to stay at the edge of AI."

It suits founders and operators with a team best, since the company agent lives in a shared Slack and Every sells its training to companies. If you run your business alone, you can still learn a lot from the writing, but you'll be scaling it down to one person yourself.

Ben's Bites: Building With Agents In Public

Ben describes Ben's Bites as "what I'm learning building with agents (plus tools worth trying)." His about page says it's mostly stories of founders and companies who build things differently, and that he shares what he builds along the way, usually in one or two emails a week. The recent posts are all free to read.

Pick Ben's Bites if you enjoy the building as much as the result and want to follow someone working it out in public. If you'd rather get a finished system and spend as little time as possible setting it up, you'll be doing the building Ben writes about yourself.

AI With Allie: A Structured Start With AI

Allie K. Miller's newsletter, AI with ALLIE, promises "turning AI buzzwords into business tactics." It's free, new subscribers get a 50-page ChatGPT guide, and her free AI Fast Track is a five-day email course that goes from the basics to building your own tools. Her paid material includes the AI-First Academy, which she aims at "business professionals ready to lead with AI," and a $499 Enterprise AI Mastery Toolkit, with more courses on LinkedIn Learning and MasterClass.

Pick AI with Allie if you're early with AI and want a structured way in, or if you're leading AI inside a company. If you're past the basics and run a small business of your own, most of her paid material targets someone else: the people bringing AI into a larger company.

Greg's Letter: Startup Ideas And Free Guides

Greg Isenberg sends Greg's Letter every week, "jam-packed with free startup ideas, insights on business building and ways to win in an internet world." His site also offers guides, among them The Agents Skill Suite, an AI Content Automation Guide, an Obsidian + Claude Code Codebook and The $500K Funnel Blueprint.

Pick Greg's Letter if you're looking for the next business to start, or a new growth play, and you'd like starter material on agents and Claude Code while you look. It's a weaker fit once you have the customers and your problem is making the business you already run work better.

Lenny's Newsletter: Product And Growth Advice For Tech

Lenny Rachitsky calls Lenny's Newsletter "a deeply researched advice column about building product, driving growth, and advancing your career," and he writes it for product leaders, founders and builders. It costs $20 a month, $200 a year, or $400 a year for the Insider tier. Annual and Insider subscribers get Product Pass, a free year of premium AI and product tools (19 of them on annual, all 32 on Insider), plus a Slack community of more than 30,000 members.

Pick Lenny's if your job is product or growth at a tech company. If you run an online business on your own, Lenny is writing for a different job than yours.

Bionic Business: AI Systems For Online Entrepreneurs With Customers

I write Bionic Business for the online entrepreneur who already has customers and makes every call personally: consultants and coaches first, then agency owners, freelancers and publishers, most of them working alone or with a few contractors.

Most issues hand you a working system for one part of the business, such as following up on leads, qualifying them, writing in your voice or reading your numbers every week, and one person can run it on the tools you already pay for. The systems come from my own businesses and from client work, and when a build fails I write that up too.

I've worked in machine learning since 2016 and with generative AI since 2019, and I've published Bionic Business since February 2023.

There's a free issue most weeks, with agent builds that include the full prompts, guides to connecting ChatGPT or Claude to tools like your email platform, and The Scan, a round-up of AI news where every item ends with one call: use it now, wait, or ignore.

Cortex, the paid tier, costs $50 a month and ships the installable versions of those systems (Skills, agent packs and starter kits you load into Claude or ChatGPT).

Pick Bionic Business if you have the business and the customers, you use ChatGPT or Claude every day, and you want agents doing real work inside the business without learning to code or hiring someone.

When Bionic Business Is The Wrong Pick

I'd point you to one of the others in five situations:

You want AI news fast and often. The Scan comes about once a month and gives a verdict on fewer items. Ben's Bites usually lands once or twice a week.

You don't have a business yet. Almost everything I write assumes customers, a list or a pipeline, and Greg writes Greg's Letter for people still finding the idea.

AI is part of your job inside a company. Every, AI with Allie and Lenny's each write for a version of that situation.

You compare on price. Cortex at $50 a month costs more than Every ($30) or Lenny's ($20). I price it on the systems it ships, so if you're after paid reading at a lower price, either of those is the cheaper choice.

You want a community to talk in. Bionic Business has no member community. Lenny's has a Slack of more than 30,000 members.
