I Built 5 Free AI Tools That Replace $200/month in SaaS Subscriptions

A developer built five free AI tools that replace $200/month in SaaS subscriptions, including a content writer, email writer, social media caption generator, code assistant, and file converter. The tools are available at bigwinner.work/ai-tools with a free tier offering five uses per day per tool. The developer used free AI APIs from Pollinations, OpenRouter, and Groq, and emphasized that UI matters more than the underlying model.

I was paying $47 for ChatGPT Plus, $29 for Jasper, $19 for Grammarly, $16 for Copy.ai, and $15 for an SEO tool. That's $126/month just for AI writing tools. So I built my own. Five tools, one dashboard, completely free to start. Here's how each one works and what it replaces. The content writer generates blog posts, articles, product descriptions, and marketing copy. You pick: The key difference from Jasper: no templates, no "brand voice" setup. You just describe what you want and get it. Simpler, faster. This one handles the emails I hate writing: You set the formality level formal, semi-formal, casual and urgency. It writes the subject line AND the body. I've used it for 50+ cold emails last month. Generates 3 caption variations per request. Platform-specific: Options for emojis, hashtags, and CTAs are toggleable. You can mix and match from the 3 generated options. Five modes: Supports Python, JavaScript, TypeScript, Java, C++, Go, Rust, SQL, and more. Not as deeply integrated as Copilot in VS Code, but it's the tool I reach for when I need a quick answer outside my IDE. Four tasks: All five tools share one dashboard. No signup, no email, no credit card. Each tool has a free tier: 5 uses per day. The tech stack is deliberately simple: | Plan | Price | What You Get | |---|---|---| | Free | $0 | 5 uses/tool/day 25 total | | Starter | $9/mo | Unlimited uses, all tools | | Pro | $29/mo | Unlimited + API access + priority | Free AI APIs are good enough for most tasks. Pollinations, OpenRouter free tier, and Groq's free tier handle 90% of content generation needs. PHP is underrated for simple proxies. Everyone reaches for Node.js, but a 50-line PHP file handles CORS proxying perfectly with zero dependencies. Rate limiting is essential for free tiers. Without it, one user could burn through your API budget in minutes. I use per-IP daily limits with a temp file counter. The UI matters more than the model. Users don't care which LLM generates their caption. They care about: is the interface clean, are the options clear, does it work in 2 clicks? "Free" is the best marketing. No signup friction means people actually try the tools. Conversion happens organically when they hit the 5-use limit. All five tools are live at bigwinner.work/ai-tools https://bigwinner.work/ai-tools/ . Free tier requires no account. What AI tools are you paying for that you could replace with a simple build? I'd love to hear what others have shipped. Disclaimer: I built these tools. They're free to use. The pricing page links to my Gumroad store for paid plans. This isn't a sponsored post — just sharing what I built and why.
