We love ChatGPT and use it daily.

What is ChatGPT?

What really is there to say? ChatGPT was the fastest-growing consumer app in history when it launched. It reached 1 million users in about 5 days after launch and 100 million users in about 2 months after launch.

OpenAI is general artificial intelligence. You can ask it questions, and it'll answer them, like a human. You can ask it to write code for you, and it'll build it, all while explaining the why and how.

Engineering friends of mine are worried that it'll replace their job, and yet they are using it to become a better engineer (using it to teach them different coding languages).

The craziest thing of it all, anyone can use it, and you don't even need to be technical to use it. Just visit ChatGPT here and start asking it questions. You'll be amazed by what it can do. If you're more technical, then be sure to check out the actual API and see where you can fit it into what you're building (I mean everyone else is).

Everyone is trying to build a OpenAI (ChatGPT) into their product right now. It's the closest thing we've seen to magic in an incredibly long time.

Claude

Best for thoughtful reasoning and execution

There is a reason Claude is getting a ton of attention right now. It's genuinely good for getting work done, coding, and writing. But as a small business, be careful how deep down the rabbit hole you go.

Use it as a writing partner, a thinking partner, a research tool. But if you're a small business owner, don't try to use Claude to vibe code your own software (I promise you, your team will be frustrated and you'll abandon it within 30 days 🫠).

Go to Claude site

What is Claude?

Claude is an AI assistant built by Anthropic, designed for professionals and operators who need more than a generic AI response. It tends to follow complex instructions more completely, sounds less generic, and holds onto more context when you give it a lot to work with. There's also Claude Code for developers and Claude Cowork, a desktop agent that works with files on your machine.

I'll be honest, I resisted trying Claude for a while. I'd been using ChatGPT for two years and it knows me and my writing style incredibly well. Every time I tried Claude before really committing to it, I was disappointed because it just lacked that context, and I'd walk away thinking "I don't get what everyone's talking about!" But the hype kept coming from people I respected, so I couldn't shake the feeling that I was missing something.

What changed it for me was exporting all of my writing instructions from ChatGPT and loading them into Claude as a skill. After that, the experience improved dramatically. Claude started asking better questions and the writing output got a lot closer to what I actually wanted. Now I find myself reaching for Claude specifically when I'm doing deeper writing work. It pauses to ask clarifying questions more than ChatGPT does, and it genuinely seems to honor the context I've given it rather than just acknowledging it and moving on.

Is that because Claude is naturally more thoughtful, or because my prompt told it to ask more questions? Honestly, hard to say. Without the skill loaded in, my earlier experience was nowhere near as impressive as the internet made it sound. So if you're going to try Claude and you already have a strong writing brief (or any other brief) somewhere, move it over before you form an opinion.

Where it still falls short is the surrounding product experience, the Chrome extension, the cross-device memory in Cowork. Those feel like areas where ChatGPT has just gone a lot deeper on the day-to-day user experience, and you notice the gap when you hit them. For now I'm keeping both, especially because I use ChatGPT Atlas for browser work.

Pros and Cons

Pros

Copy Link

Automatically references your skills and writing briefs without being told to
Longer context window means it holds onto more when you give it a lot of input
Claude Code is loved by engineers

Cons

Copy Link

Chrome extension has no memory, close it accidentally and everything is gone
Cowork context doesn't persist across devices
Usage limits are annoying, we hit them fast doing deep research on the standard tier
Cowork is less useful if your whole workflow lives in web apps

Key Features

Reasoning and Writing

Copy Link

Claude gives more complete answers without turning into an endless refinement loop. ChatGPT has a habit of ending every response with "want me to improve this?" and you end up going in circles. Claude just answers, and the conversation tapers naturally unless you push it further.

Skills

Copy Link

Claude automatically references your writing brief or skill in every relevant chat without you asking. With ChatGPT you have to actively add chats to a project to get that same behavior. It's a small thing that ends up mattering a lot when you're opening new chats constantly throughout the day.

Claude Cowork

Copy Link

Cowork is Claude's desktop agent, it can take actions across your computer, work through tasks, and integrate with your tools. If you work heavily out of local folders and project files, you'll probably get a lot out of it. For me, my whole workflow lives in apps like Superhuman Mail, Linear, and Granola, so it hasn't been life-changing.

Pricing

Free: Limited access, good for testing the product before committing.
Pro: $20/month. This is the tier most founders and operators will want. Gives you access to the full model and the features that actually matter for daily work.
Max: $100/month. Higher usage limits and more capacity for longer, more intensive sessions. Worth considering if you're hitting limits regularly.
Team: $30/month per user (minimum 5 users). Adds collaboration features and admin controls for teams.
Enterprise: Custom pricing. Expanded security, compliance, and deployment options for larger organizations.

OpenClaw

Insecure general AI assistant

OpenClaw lets you run an AI agent on your own computer that can control your apps and files, but everyone with security experience says it's a huge risk and not safe for anything important. If you're a builder or hobbyist who wants to experiment on a spare device and don't care about privacy or security, it could be a fun project.

If you run a real business or have anything to lose, you should absolutely avoid it until a secure version exists.

Go to OpenClaw site

What is OpenClaw?

OpenClaw is an experimental AI agent that can do tasks for you. Unlike ChatGPT or Claude, it can take actions across anything on your device. Your folders, your browsers, tools, etc.

However, it coms with serious security risks. Being upfront, I have not personally installed OpenClaw on any of my own devices. I’ve spoken to a lot of people who have used it, including my father, who has worked in cybersecurity for over two decades and has installed it 6 or so times by now (more about his experience in our full OpenClaw Review).

The consistent theme from everyone I trust is this: no one feels fully confident that their setup is actually secure.

Right now, the risk just doesn’t match the reward.

Sintra AI

Best for non-technical business owners

Sintra is built for non-technical business owners who have very little knowledge of how to use AI and want a very easy introduction. Sintra's AI "helpers" are like digital consultants that give you ideas fast, without needing any prompting making it super easy to use.

Would we recommend it to more serious business owner who already uses tools like ChatGPT? No. For serious operators, it more so feels like playing a business-themed video game.

Go to Sintra AI site

What is Sintra AI?

Sintra is an AI-powered business assistant for people who have very little experience using AI but want to dabble more with it. Instead of you prompting the AI, Sintra's "helpers" ask you simple questions, review your website, and proactively suggest business tasks like improving web copy, writing email sequences, or creating content calendars. It’s designed to make AI feel fun and easy for overwhelmed business owners.

Pros and Cons

Pros

Copy Link

Extremely easy to use, no prompt engineering needed
Gamified onboarding, feels more like a game than a tool
AI Helpers are proactive, they suggest work rather than wait for your input
Gets better the more it learns about your business

Cons

Copy Link

Underwhelming execution, the work it "does" is 20–30% usable at best
Not for serious users, feels very “kiddish”
Data sensitivity concerns, it asked deeply personal business questions that we did not feel comfortable answering
Short-lived value, after the first day of using Sintra the novelty wore off
No free tier, you pay upfront to try it (although you can request a refund within the first 2 weeks if you're not impressed)

Pricing

$97/month with an ongoing 60% off discount
We signed up with the monthly tier and upon creating an account, we were immediately offered a 70% off annual discount
