7 AI Tools Under $20/Month That Run My Entire Business

There's a myth in the solopreneur world that you need expensive tools to compete. That you need the $125/month Jasper plan, the $599/month Zapier tier, and a $74/month Intercom subscription just to get started.

That's nonsense.

We run an entire business on AI tools that cost less than $20 each per month. The total stack is under $100/month — and honestly, you could cut it to under $50 if you had to.

Here are the 7 tools we actually use every day, what each one costs, and why we chose them over the expensive alternatives.

1. Claude Pro — $20/month

What it replaces: Content writer ($500-2,000/month), copywriter for emails and proposals

This is our most-used tool by far. Every email draft, blog outline, social post, and client proposal starts here. The writing quality is noticeably better than ChatGPT for long-form content — it sounds more natural and needs less editing.

Why not ChatGPT Plus? We've used both extensively. ChatGPT is great for quick creative tasks and has more plugins. But for the core solopreneur writing tasks — emails, proposals, articles — Claude consistently produces better first drafts. We edit less, which saves time.

Why not Jasper ($49-125/month)? Jasper is good, but it's designed for marketing teams with big budgets. For a solo business, Claude does 90% of what Jasper does at less than half the price. The 10% Jasper does better (brand voice templates, marketing workflows) isn't worth the $100+ premium.

Daily usage: 2-3 hours

2. Make (Integromat) — $9/month

What it replaces: Virtual assistant for repetitive tasks ($300-800/month)

Make connects all our apps and runs automations in the background. When a client fills a form, Make creates the task, sends the welcome email, and updates the CRM. When an invoice is paid, Make sends the thank-you note and updates the records. All without us touching anything.

Why not Zapier ($20-49/month)? We covered this in depth in our Zapier vs Make comparison. The short version: Make gives you 10,000 operations for $9/month. Zapier gives you 750 tasks for $20/month. We run the exact same automations for one-fifth the price.

Daily usage: Runs 24/7 in the background (we check it maybe 10 minutes/day)

3. Notion (with AI) — $18/month

What it replaces: Project manager ($10-30/month) + note-taking app ($10/month) + wiki ($10/month) + basic CRM ($0-30/month)

Notion is our business operating system. Client database, project tracker, content calendar, meeting notes, standard operating procedures — everything lives in one place. The AI add-on lets us search across everything instantly and generates summaries of long documents.

Why not separate tools? Before Notion, we used Trello for projects ($10/month), Google Keep for notes (free), Confluence for docs ($6/month), and a spreadsheet for client tracking. Four tools doing what one tool does better. The consolidation alone saves 30 minutes a day in switching between apps.

Daily usage: 1-2 hours (it's where we live)

4. Canva Pro — $15/month

What it replaces: Graphic designer for social media ($200-500/month)

Every social media graphic, presentation slide, email header, and marketing one-pager we create comes from Canva. The AI features (Magic Edit, background removal, text-to-image) handle 90% of what used to require Photoshop skills.

Why not Figma or Adobe? Figma is designed for UI designers. Adobe Creative Suite is designed for professionals. Neither is designed for a solopreneur who needs a LinkedIn post graphic in 3 minutes. Canva is, and it does that job perfectly.

The free version is good too. If $15/month is too much right now, Canva Free handles basic graphics well. The paid version adds the brand kit (which keeps everything consistent) and premium templates. Worth upgrading when you can, but not essential to start.

Daily usage: 20-30 minutes

5. Tidio — $0-29/month

What it replaces: Customer support person for basic inquiries ($500-1,500/month)

The AI chatbot on our website handles the questions we used to answer manually — pricing, timelines, how to get started, portfolio requests. It learned our FAQs in about an hour of setup and now handles roughly 70% of incoming inquiries without us doing anything.

Why not Intercom ($74-999/month)? Intercom is the gold standard of customer messaging platforms. It's also priced for VC-funded startups, not solopreneurs. Tidio does 80% of what Intercom does at a fraction of the price. The 20% we miss (advanced analytics, sophisticated routing) isn't worth $50-900/month more.

The free plan works. For businesses getting fewer than 50 inquiries per month, Tidio's free plan is enough. We upgraded to the $29 plan when our volume increased, but we ran on the free plan for the first three months.

Daily usage: 5 minutes (checking the conversations the bot couldn't handle)

6. Grammarly — $12/month

What it replaces: Proofreader ($50-200/month)

Everything we write goes through Grammarly before it goes out. Emails, blog posts, proposals, social media captions. It catches the typos and awkward phrases that slip past us when we're moving fast. The tone detection is surprisingly useful — it flags when an email sounds too aggressive or too passive.

Why not just use AI writing tools for this? We do use Claude for drafting, but Claude doesn't catch every typo in text we write ourselves. Grammarly runs as a browser extension — it's always on, checking everything we type, everywhere. Different job from an AI writing assistant.

Daily usage: Always on in the background

7. Otter.ai — $16.99/month

What it replaces: Meeting note-taker ($100-300/month), transcription service ($50-200/month)

Otter joins our meetings, transcribes everything, identifies action items, and creates a searchable summary. Before Otter, we spent 15-20 minutes after every meeting writing up notes. Now it's done automatically, and it's more accurate than our own notes because it captures everything — not just what we remembered to write down.

Why this matters for solopreneurs: When you're the only person in the business, there's nobody else to take notes while you're talking. Otter solves that completely. It also creates a searchable archive of every meeting — incredibly useful when a client says "but you said..." and you can pull up the exact transcript.

Daily usage: During every meeting (3-5 per week)

The Complete Cost Breakdown

The math speaks for itself. Under $120/month for tools that would cost $1,700-5,400/month in human equivalents. Even if the AI tools only do 80% as well as a human (which is generous — in many cases they're better), the ROI is overwhelming.

The Budget Stack (Under $30/month)

If even $120/month feels like too much, here's what we'd keep on a tight budget:

• Claude Pro ($20) — this is the one tool we wouldn't give up
• Make free plan ($0) — 1,000 operations, enough to start
• Notion free ($0) — limited but functional
• Canva free ($0) — basic but covers essentials
• Tidio free ($0) — handles low volume
• Grammarly free ($0) — basic grammar checks
• Otter.ai free ($0) — limited minutes but usable

Total: $20/month for a functional AI business stack. For a more comprehensive look at every category, check out the complete 2026 solopreneur AI stack.

What This Stack Can't Do

We're not going to pretend AI tools replace everything. Here's what still needs a human:

• Strategy and judgment calls — AI can help brainstorm but can't set your business direction
• Complex negotiations — client relationships still need your personal touch
• Creative vision — AI executes but doesn't originate truly novel ideas
• Crisis management — when things go wrong, you need human adaptability

These are the things worth spending YOUR time on. Let the tools handle the rest.
