The 5 AI tools I use every single day as a solopreneur

I get asked this question more than any other: which AI tools do you actually use every single day?

The honest answer is shorter than people expect. Five. Not twenty. Most "best AI tools" lists are written by affiliates who get paid per signup, so they include every tool with a referral programme regardless of whether real freelancers use them. This list is different. These are the only five I open before my first coffee, every working day, without exception.

If you are starting from zero and want a working stack rather than a list to research for three weeks, this is it.

1. Claude (paid, $20/month)

The workhorse. Claude handles 70% of my AI usage — long-form writing, client emails, proposals, research synthesis, editing my own drafts, and most of the prompts in the Solopreneur AI Toolkit. The reason it stays at the top of my stack is voice. Claude writes in a way that requires minimal editing before it sounds like a real person wrote it, which is the single most important quality for client work.

I use the paid tier ($20/month). The free tier is enough for casual users, but anyone doing meaningful daily work hits the limits quickly. Paid removes that friction entirely.

2. ChatGPT (paid, $20/month)

The complement, not the replacement. ChatGPT covers the 20% of tasks Claude is not as good at — image generation, voice conversations for walking-and-brainstorming, and custom GPTs that hold specific instructions across sessions. The "should I use Claude or ChatGPT" debate is a false binary. Use both for what each does best.

Specifically, I keep ChatGPT around for: generating thumbnail concepts when working on visual content, voice brainstorming during longer walks, and as a second opinion when Claude is being weird about something specific.

3. Cal.com (free tier)

Not an AI tool, but indispensable in an AI-powered workflow. Cal.com handles all my discovery calls, client check-ins, and intro meetings. When a cold outreach email lands a reply, my standard response includes a Cal.com link. The friction from "let's find a time" to "booked" goes from 4 emails to zero.

I use it free. The paid tier adds features I do not need as a solo operator. It connects directly to Google Calendar and Stripe — useful if you want to charge for paid consultations.

4. Notion (free tier, with Notion AI optional)

My captured information lives in Notion. Client projects, prompt library, ideas inbox, content calendar, newsletter drafts, financial tracking — all in one workspace. The reason I prefer Notion over other tools is that everything is searchable across context. When I need to remember what I told a client three months ago about their project, Notion finds it in a second.

Notion AI is bolted on top ($10/month add-on). It is useful but not essential — I keep it off and use Claude for AI tasks instead. The structure of Notion itself is what earns it a daily-use spot, not the AI layer.

5. Cursor (free tier or paid, $20/month)

This one surprises people. Cursor is technically a code editor, but it is also the fastest way to edit and ship HTML for a content site like this one. I use it to generate new article pages, tweak the site design, and handle anything that involves touching code. The AI assistance is built directly into the editor, which means I can describe what I want in plain English and watch it write the change.

If you are not technical at all, you might not need this. But the moment your business involves any code — even just maintaining your own website — Cursor becomes worth its weight in saved hours.

The total cost

$40-60/month for the entire stack, depending on which paid tiers you pick up. Compare that to a single hour of a freelancer's billable time, and the math is obvious. The stack pays for itself in the first 30 minutes of use each week.

What I deliberately do not use

Equally important — the tools I have tried and intentionally do not keep around:

• Jasper, Copy.ai, Writesonic — these are wrappers around the same models Claude and ChatGPT run on, charging you more for templates you can prompt yourself in 30 seconds
• Zapier AI Actions — useful for businesses with multiple humans, overkill for a solopreneur who can just chain prompts manually
• AI scheduling tools (Reclaim, Motion) — they create more friction than they remove for a one-person business with a simple calendar
• "AI agent" platforms — the marketing is ahead of the reality, and you are better off prompting the underlying models directly

How to start if you have none of this

Do not buy everything at once. Start with Claude free tier and Cal.com free tier — that combination covers 80% of what a beginner freelancer needs. Add ChatGPT free or paid in month two if you find specific tasks Claude struggles with. Add Notion in month three when your captured information starts to overwhelm a single text file. Add Cursor only if your business genuinely involves code.

The temptation when you discover AI tools is to subscribe to ten of them at once and then never use seven. Resist this. The freelancers who get the most out of AI use very few tools, very deeply. Five is enough. Five is plenty.
