A new survey just came out saying 63% of small businesses have fewer than three months of cash reserves. Meanwhile, everybody's telling you to "invest in AI tools" to stay competitive.
Cool. So you should spend money you don't have on tools you're not sure about. Got it.
Look. I get the tension. As someone who's been solo for years, every subscription is a negotiation between "this could save me time" and "that's my grocery money." So let me give you something practical: the AI stack I'd build today if I were starting from zero, for under $50/month total.
The $47/month stack
1. ChatGPT Plus - $20/month
This is your workhorse. Not for writing your content (please don't publish raw ChatGPT output). For everything else:
- Brainstorming business ideas and strategies
- Drafting emails you'll edit in your own voice
- Analyzing spreadsheets and financial data
- Researching competitors
- Creating SOPs for processes you want to systematize
- Building simple automations with its new agent features
I use it 15 to 20 times a day. It's the best $20 I spend.
2. Canva Pro - $13/month
You need visuals. Social posts, proposals, invoices that don't look like they were made in Word. Canva's AI features now include:
- Image generation (good enough for social media)
- Background removal
- Auto-resize for every platform
- Brand kit so everything looks consistent
- Magic Write for quick copy when you're stuck
If you're posting on social media, pitching clients, or sending proposals, this pays for itself in the first week.
3. Otter.ai Basic - $0/month (free tier)
If you have meetings - client calls, sales calls, vendor calls - Otter records and transcribes them. The free tier gives you 300 minutes per month. That's about 10 thirty-minute calls.
For a solopreneur, that's usually enough. You get searchable transcripts, which means you can go back and find exactly what a client said instead of relying on memory.
4. Zapier Free Tier - $0/month
The free tier gives you five automations (called "Zaps"). That's enough to set up:
- New contact form submission automatically added to a spreadsheet
- New invoice sent automatically logs to your accounting tracker
- Daily weather/news summary sent to your email
- Social media auto-posting from a content calendar
Five automations doesn't sound like much, but for a solo operation, it covers the essentials.
5. Notion (with AI) - $14/month
Your second brain. Project tracker, client database, content calendar, notes, SOPs - all in one place. The AI features let you:
- Summarize long documents
- Turn meeting notes into action items
- Generate first drafts of project briefs
- Search across everything you've ever written in Notion
Some solopreneurs use Google Docs and Sheets for this. That works too, and it's free. But if you want everything in one searchable place with AI built in, Notion is worth the $14.
Total: $47/month
What's NOT on this list (and why)
Jasper ($29/month): Great tool, but if you're already using ChatGPT Plus, there's too much overlap. Jasper is better for dedicated content teams.
Midjourney ($10/month): Unless you need custom images regularly, Canva's built-in AI image generation covers most social media needs.
Any CRM ($25 to $100/month): Controversial take: if you have fewer than 50 clients, a Notion database or Google Sheet works fine. Don't pay for a CRM until you're actually losing track of people.
Any "AI agent" platform ($50 to $300/month): It's 2026 and these are still too expensive and too complicated for most solopreneurs. Wait six months.
The real cost isn't money
Here's what nobody tells you about AI tools: the biggest cost isn't the subscription. It's the time you spend learning them, configuring them, troubleshooting them, and switching between them.
That's why I keep this stack small. Five tools. Under $50. I know them well enough that they actually save time instead of eating it.
The worst thing you can do is sign up for eight AI tools because some influencer posted a "must-have AI stack" thread on X. You'll spend more time managing your tools than running your business.
Start with what you need. Add when you outgrow it. Delete what you don't use.
That's the whole strategy.
