The Free AI Content Stack That Actually Works in 2026
📑 Table of Contents
🎯 Quick Summary
Five tools. Zero monthly cost. Gemini handles writing, Tavily handles research, Make.com handles automation, Google Sheets handles your content database, and WordPress handles publishing. Each has a free tier generous enough to run a real content operation — not a toy project.
Most “free AI tool” lists are dishonest. They recommend tools with free tiers so limited they’re useless in practice — 3 generations a day, 10 API calls a month, watermarks everywhere. But there’s a specific combination of five tools in 2026 where the free tiers are genuinely functional. Not trial-mode functional. Actually functional.
This guide covers exactly that stack — what each tool does, why the free tier is enough to start, and how they fit together into a workflow. If you’re building a content site, a niche blog, or just experimenting with AI-assisted publishing, this is where to begin.
Why Free Tiers Are Enough (For Now)
The economics of AI tooling changed significantly in 2025 and 2026. Model costs dropped, free tier limits expanded, and several tools that previously required paid plans opened up meaningful free access. Gemini’s API free tier now supports 1,500 requests per day. Tavily’s free plan covers 1,000 API calls per month. Make.com’s free plan includes 1,000 operations per month across 2 active scenarios.
None of those numbers are huge. But they’re enough to publish several well-researched articles per week without spending a dollar. The key is designing your workflow to use operations efficiently — which is most of what this series of guides covers.
The 5 Tools in the Stack
1. Google Gemini API — The Writer
Gemini is Google’s flagship AI model family. The API’s free tier (via Google AI Studio) gives you access to Gemini 2.0 Flash — fast, capable, and surprisingly good at following complex structured prompts. At 1,500 requests per day on the free tier, it’s not a bottleneck for most solo content operations.
Why Gemini over ChatGPT here? Primarily the free API access. OpenAI’s API has no meaningful free tier for production use. Gemini does. For a cost-zero workflow, that’s the deciding factor.
2. Tavily — The Researcher
Tavily is an AI-optimised search API built specifically for LLM workflows. Unlike scraping Google yourself or paying for a Serper subscription, Tavily returns structured research results — URLs, titles, raw page content — in a format that feeds directly into an AI prompt. The free tier is 1,000 API calls per month.
This is the tool most people haven’t heard of. And it’s the one that makes the biggest difference to output quality. AI writing without real-time research produces generic content. Tavily fixes that.
3. Make.com — The Automation Layer
Make.com (formerly Integromat) is a no-code automation platform. You build visual workflows — called scenarios — that connect apps and run logic without writing code. The free plan gives you 2 active scenarios and 1,000 operations per month. That’s tight but workable if you design lean.
Think of Make.com as the glue. It watches your Google Sheet, fires the research call to Tavily, passes the result to Gemini, and sends the output to WordPress. You configure it once. Then it runs.
4. Google Sheets — The Content Database
Free, familiar, and deeply integrated with Make.com’s Google Sheets module. Your Sheets spreadsheet acts as a lightweight CMS — a list of article topics with columns for status, keyword, category, and priority. When you mark a row as ready, Make.com picks it up and kicks off the workflow.
No database setup. No backend. Just a spreadsheet that drives the whole operation.
5. WordPress — The Publisher
Self-hosted WordPress with a cheap shared hosting plan (Hostinger starts at around $3/month) gives you full REST API access, custom fields, and complete control over your output. Make.com posts directly to WordPress via the REST API — no plugin required beyond Application Passwords, which is built into WordPress core since 5.6.
How They Connect
The flow is linear and simple. Google Sheets is the trigger. Everything else is a consequence.
- You add a row to your Google Sheet with a topic, keyword, and status set to “Approved”
- Make.com detects the new approved row (checks on a schedule you set)
- Make.com calls Tavily with a research query based on your topic
- Tavily returns real-time web research — current pricing, benchmarks, reviews
- Make.com passes the research + your prompt to Gemini API
- Gemini writes the article in your specified format
- Make.com posts the result to WordPress via REST API as a draft
- Make.com updates the Google Sheet row status to “Published”
That’s it. Eight steps. No code. The whole thing runs in under two minutes per article once it’s set up.
status: draft first. Review the output before it goes live. As you refine your prompt and get consistent quality, you can switch to auto-publish — but not before you trust the output.
Honest Free Tier Limits
The free stack works. But it has real constraints worth knowing upfront.
| Tool | Free Limit | Articles Per Month (Approx) | Bottleneck? |
|---|---|---|---|
| Gemini API | 1,500 req/day | ~45,000 | No |
| Tavily | 1,000 calls/month | ~1,000 | No |
| Make.com | 1,000 ops/month | ~100–125 | Yes — design lean |
| Google Sheets | Unlimited | Unlimited | No |
| WordPress REST API | Unlimited | Unlimited | No |
Make.com is the constraint. Each scenario run uses roughly 8–10 operations depending on how many modules you have. At 1,000 ops/month that gives you around 100–125 article runs before you hit the limit. For most solo content operations publishing 3–5 articles per week, that’s fine. Scale beyond that and you’ll want Make.com’s Core plan at $9/month.
Getting Started Today
Here’s the exact sequence to get the stack running. Each of these is covered in depth in the individual guides in this series — but this is your orientation checklist.

❓ Frequently Asked Questions
Can I really run this entire stack for free?
Yes — with one caveat. The five tools (Gemini API, Tavily, Make.com, Google Sheets, WordPress core) are all free. You still need WordPress hosting, which runs $3–10/month on shared plans. If you already have a WordPress site, the automation layer costs nothing to build and run at moderate volume.
How many articles can I publish per month on the free plan?
Make.com’s 1,000 operations/month is the binding constraint. Each article run uses roughly 8–10 operations depending on your scenario complexity, giving you around 100–125 article runs per month. Tavily’s 1,000 calls/month and Gemini’s 1,500 daily requests won’t be the bottleneck at that volume.
Do I need to know how to code?
No. Make.com is entirely visual — you connect modules by dragging and clicking. The WordPress REST API connection requires copying an Application Password from your WordPress dashboard, but no code is written. The only technical skill involved is writing a good AI prompt, which this series covers in Guide 4.
Why Make.com instead of Zapier or n8n?
Zapier’s free plan is too limited for this workflow — 5 zaps and 100 tasks/month. n8n is powerful but self-hosted, adding infrastructure complexity. Make.com’s free plan sits in the sweet spot: generous enough to run a real scenario, visual enough to build without code, and with native Google Sheets and HTTP modules that handle every connection in this stack.
Is AI-generated content good enough to publish directly?
With a well-engineered prompt and real-time research data, quality is high enough to publish after a light review — not raw generation without oversight. Always publish to WordPress as a draft first, read it, make adjustments. The goal is AI as a first draft engine, not a replacement for editorial judgment.
