The honest guide to AI pricing: what actually costs money vs what's free
Most small business owners either overpay for AI tools they barely use, or avoid them entirely because they assume they can't afford it. Here's what the AI stack actually costs — and what you genuinely get for free.
Before we get into the numbers, let's deal with the assumption that's holding back a lot of small business owners: that AI tools are expensive.
Some are. Enterprise AI software sold to large organisations can cost thousands of dollars a month. But the tools that are actually useful to a five-person business? Most of them have genuinely functional free tiers. The ones worth paying for are typically $10–$30 a month. A complete AI stack that covers content creation, customer service, email marketing, and admin automation can be run for under $50 a month — and in many cases, for nothing at all.
The more common problem isn't that AI is too expensive. It's that business owners sign up for too many tools, each solving a slightly overlapping problem, and end up paying $200 a month for software they use at 20% capacity.
This guide tells you exactly what you're getting at the free tier of every major AI tool, where the free tier runs out and a paid plan starts to make sense, and what a sensible AI stack looks like at three different budget levels. No affiliate marketing, no sponsored placements — just the honest version.
The free tier reality check
Every major AI tool has a free tier. Here's what you actually get on each one — not the marketing version, the real version.
ChatGPT (OpenAI)
Free tier: Access to GPT-4o with usage limits. In practice, you can have several substantive conversations per day before hitting any restriction. Writing prompts, drafting emails, answering questions, brainstorming — all covered. You will occasionally get a message saying you've hit a limit, at which point the tool temporarily switches to an older model or asks you to wait an hour.
What you lose on the free tier: Consistent access to the latest model during peak hours, the ability to create custom GPTs (saved configurations with your instructions baked in), access to Advanced Voice Mode, and image generation via DALL-E.
When to upgrade to Plus ($20/month): When you're using ChatGPT daily for work tasks and the usage limits are actually interrupting your workflow — not because you bumped into a limit once. Also worth it if you want to build a custom GPT with your voice document and business information pre-loaded.
Verdict: The free tier covers 80% of what most small business owners need from ChatGPT. Don't upgrade until the limits genuinely affect your work.
Claude (Anthropic)
Free tier: Access to Claude Sonnet — a genuinely capable model — with daily usage limits. Claude is particularly strong at writing tasks, nuanced reasoning, and following detailed instructions. For drafting content, editing copy, and working through business problems, it's arguably better than ChatGPT's free tier for writing-heavy work.
What you lose on the free tier: Access to Claude Opus (the most powerful model in the family), higher usage limits, and the ability to create Projects — saved workspaces where you can store your voice document, business context, and conversation history so Claude remembers your preferences across sessions.
When to upgrade to Pro ($20/month): If you're using Claude for content production daily, the Projects feature alone is worth the upgrade — it eliminates the need to re-paste your voice document every session and maintains context across conversations. Also worthwhile if you're hitting usage limits regularly.
Verdict: For writing-heavy tasks, Claude's free tier is excellent. If you find yourself choosing between upgrading ChatGPT or Claude, think about which one you use more for writing vs for answering questions and research — they have different strengths.
Google Gemini
Free tier: Access to Gemini 1.5 Pro with usage limits. Particularly strong for tasks that benefit from Google integration — summarising documents in Google Drive, working within Google Docs and Sheets, and research tasks that benefit from real-time web access. Free tier is genuinely useful.
What you lose on the free tier: Gemini Advanced (the more powerful model), higher upload limits for documents and files, and the ability to create custom Gems (saved AI configurations).
When to upgrade to Google One AI Premium ($19.99/month): If you're already paying for Google Workspace and use Google Docs, Sheets, and Drive heavily, the integration value is real. If you don't live in Google's ecosystem, there are better options at this price point.
Verdict: Best value for businesses that already use Google Workspace. Less compelling if you're not in that ecosystem.
Perplexity
Free tier: Access to a capable AI search engine that gives sourced answers to questions. Better than Google for research questions that need a synthesised answer rather than a list of links to click through. Useful for competitive research, market analysis, and quickly getting up to speed on an unfamiliar topic.
What you lose on the free tier: Perplexity Pro gives access to more powerful models (GPT-4o, Claude, and Gemini as search backends), more file uploads, and better research depth.
When to upgrade to Pro ($20/month): If you use it heavily for research and the depth and accuracy of standard Perplexity searches isn't meeting your needs. Most small business owners don't need to upgrade.
Verdict: The free tier is genuinely useful as a research tool. Worth having in your toolkit even if you never upgrade.
The specialist tools: where you'll actually spend money
The AI writing assistants above are general-purpose. The tools below are built for specific jobs — and this is where most small businesses end up paying because the specialist tools connect to your actual business systems in ways a general AI can't.
Email marketing platforms
Beehiiv: Free up to 2,500 subscribers with full access to features including the newsletter builder, basic automation, and analytics. Paid plans start at $42/month for the Scale plan (up to 1,000 subscribers with advanced features including boosts and ad network). For most small business newsletters, the free tier lasts a long time.
Kit (formerly ConvertKit): Free up to 10,000 subscribers with one email sequence and basic landing pages. Paid plans start at $29/month. The generous free tier makes Kit worth considering if you're building an email list from scratch.
Mailchimp: Free up to 500 contacts with 1,000 sends per month. The free tier is more restrictive than it used to be. Paid plans start at $13/month. Mailchimp is better suited to retail businesses with occasional campaign sends than to publishers sending frequent newsletters.
Honest take: If you're building a newsletter for AInstein-style content, Beehiiv's free tier is hard to beat. If you're a retail or service business sending occasional promotional emails, Mailchimp or Kit's free tier covers you for a long time.
Chatbot and customer service tools
Tidio: Free plan covers basic live chat with limited AI responses (the Lyro AI is capped at 50 conversations/month on the free tier). For testing whether a chatbot works for your business, this is sufficient. Paid plans start at $29/month for more AI conversations.
Manychat: Free plan covers Instagram and Facebook DM automation with basic flows. Sufficient to start. Pro plan at $15/month removes limits and unlocks more triggers and integrations.
Intercom: Not for most small businesses. Pricing starts at $74/month and is designed for companies with dedicated customer support teams. Overkill unless you have high customer service volume.
Honest take: Start with Manychat free if your customers are on Instagram or Facebook. Start with Tidio free if they find you through your website. Upgrade only after confirming the tool is handling real conversations and you're hitting the limits regularly.
Scheduling and social media tools
Buffer: Free plan covers three social channels with 10 queued posts per channel. Sufficient for a single business posting to Instagram, Facebook, and one other platform. Paid plans from $6/month per channel.
Later: Free plan covers one social profile per platform with 30 posts per month. Works for testing. Paid from $25/month for multi-account management.
Meta Business Suite: Free, forever, for scheduling to Facebook and Instagram. No usage limits, no paid tier. If these are your only channels, there's no reason to pay for a scheduling tool.
Honest take: Meta Business Suite handles most small businesses' scheduling needs for free. Only pay for Buffer or Later if you're posting to channels outside Meta's ecosystem (LinkedIn, TikTok, Pinterest) regularly.
Automation and integration tools
Zapier: Free plan covers five "Zaps" (automated workflows) running every 15 minutes. Enough to get started with one or two automations. Paid plans from $29.99/month for more Zaps and faster execution.
Make (formerly Integromat): Free plan covers 1,000 operations per month, which is more generous than Zapier's free tier for straightforward automations. Paid from $9/month.
Honest take: For most small businesses, Zapier's free tier covers the basics. If you find yourself wanting more automations regularly, Make's free tier goes further before requiring an upgrade.
Lead generation tools
Apollo.io: Free plan gives you 10,000 export credits per month and access to the full contact database for searching and filtering. Genuinely functional for building prospect lists. Paid plans from $59/month for higher export limits and sequences.
Hunter.io: Free plan gives you 25 searches and 50 email verifications per month — enough to test a small outreach campaign. Paid from $34/month.
Honest take: Apollo's free tier is remarkably generous and covers most small business lead generation needs. The paid upgrade makes sense if you're running consistent outreach campaigns at volume.
Three budget levels: what your AI stack looks like
The free stack — $0/month
This is a genuine, functional setup — not a stripped-down compromise.
| Tool | Purpose | Cost |
|---|---|---|
| Claude or ChatGPT (free tier) | Writing, drafting, brainstorming | Free |
| Beehiiv or Kit (free tier) | Email marketing up to 2,500–10,000 subscribers | Free |
| Meta Business Suite | Social media scheduling (Facebook + Instagram) | Free |
| Tidio (free tier) | Basic website chatbot | Free |
| Apollo.io (free tier) | Prospect list building | Free |
| Zapier (free tier) | 5 basic automations | Free |
| Google Docs | Voice document, templates, SOPs | Free |
This covers: content creation, email marketing, social scheduling, basic customer service automation, lead generation, and admin automation. Every tool discussed across this entire article series, for nothing.
The limitation is usage caps — you'll hit them eventually if you're using the tools daily. But for a business just getting started with AI, the free stack runs surprisingly far before you need to upgrade anything.
The sensible paid stack — $50–$75/month
This is the level most active small businesses end up at after three to six months of using AI tools regularly.
| Tool | Purpose | Cost |
|---|---|---|
| Claude Pro or ChatGPT Plus | Daily writing, Projects/custom GPT, no limits | $20/month |
| Beehiiv Scale or Kit paid | Email list over 2,500 subscribers, full automation | $29–$42/month |
| Meta Business Suite | Social scheduling | Free |
| Manychat Pro | Instagram/Facebook DM automation | $15/month |
| Zapier Starter | More automations, faster execution | $29.99/month |
Total: ~$65–$107/month depending on which combination you need.
The honest version: most businesses at this level are using Claude Pro or ChatGPT Plus for daily writing ($20), one email platform for their list ($0–$42), and Meta Business Suite for scheduling ($0). The chatbot and automation tools are optional depending on your business type.
Realistic monthly spend for most active users: $20–$62/month.
The full stack — $150–$200/month
This is for businesses that are actively using AI across every function — content, customer service, sales, marketing, operations — and for whom the tools are generating clearly measurable return.
| Tool | Purpose | Cost |
|---|---|---|
| Claude Pro + ChatGPT Plus | Writing and research from both | $40/month |
| Beehiiv Scale | Newsletter, 1,000+ subscribers, full features | $42/month |
| Tidio paid | Full AI chatbot with more conversations | $29/month |
| Buffer Essentials | Multi-platform scheduling | $18/month |
| Apollo.io Basic | Outreach sequences, higher limits | $59/month |
| Zapier Professional | Unlimited Zaps, instant execution | $73.50/month |
Total: ~$261/month
This is the ceiling for most small businesses — and frankly, most businesses don't need to be here. The full stack makes sense when you can demonstrate that the tools are generating revenue or saving time with a clear ROI calculation.
The calculation: if your time is worth $75/hour and the tools save you 10 hours a month, the stack pays for itself at $750 in time saved per month — roughly three times the cost. That's the bar to clear before committing to the full version.
The hidden costs nobody talks about
The monthly subscription cost is only part of the picture. Here's what actually costs you time and money that doesn't show up in the pricing pages.
Setup time. Every tool in this article requires initial configuration. Chatbots need FAQ content. Email sequences need to be written. Automation workflows need to be built. Budget 2–4 hours per tool for meaningful setup. For a full stack, that's potentially two full working days of setup time before anything runs automatically.
Maintenance. Automations break. Chatbot answers go stale. Subject line strategies stop working. Budget roughly an hour a month per active tool to check, fix, and improve. This is usually less than the time the tool saves — but it's not zero.
The learning curve. Every new tool has one. The first week with any AI tool is slower than your old manual process, not faster. Give each tool three weeks before judging whether it's worth the effort.
Tool sprawl. The most common expensive mistake: signing up for too many tools that overlap, keeping them all running because cancelling feels like admitting failure, and paying for capacity you're not using. Do a quarterly audit. Cancel anything that isn't saving you at least five times its monthly cost in time or revenue.
The one-tool rule for getting started
If you currently use no AI tools and want to start: pick one. Not five. One.
The one with the fastest return for most small businesses is the AI writing assistant — Claude or ChatGPT, free tier. Use it daily for two weeks for email drafts, social captions, and any writing task that currently involves staring at a blank page. See whether it saves you time. It will. Then and only then, add the next tool.
The businesses that get the most from AI didn't adopt ten tools in one month. They adopted one, got good at it, measured the return, then added the next one when they had capacity and a clear use case. That's the approach that actually sticks.
