Most people overpay for AI tools. They subscribe to 10+ services, each $20-30/mo, totaling $300+/mo. But you only need 5-7 well-chosen tools for 90% of your work. This guide shows you how to build a personal AI stack that costs $50/mo or less and covers writing, coding, image, video, and automation.
Five tools cover 90% of personal AI work: (1) ChatGPT Plus or Claude Pro ($20/mo) for general Q&A, writing, and reasoning, (2) Cursor Pro or GitHub Copilot ($20/mo) for code, (3) Midjourney or DALL-E ($10-30/mo) for images, (4) ElevenLabs Starter ($5/mo) for voice, (5) Zapier or Make ($20/mo) for automation. Total: $75-100/mo. You can cut to $50/mo by using free tiers where possible (ChatGPT free, Cursor Hobby, Midjourney trial, ElevenLabs free, Make free).
Writing and Q&A: ChatGPT Plus or Claude Pro (text is text). Code: Cursor or GitHub Copilot (both see your repo). Image: Midjourney (best quality) or DALL-E (easiest). Video: Runway, Pika, or Sora (each has different strengths). Voice: ElevenLabs (best quality) or Play.ht (cheaper). Automation: Zapier (easiest), Make (more powerful), or n8n (free, self-hosted). For each task, use one tool. Don't overlap.
When picking within a category, use this rule: start with the free tier of the leader, test for 2 weeks, then decide. For example, in writing: try ChatGPT free for 2 weeks, then Claude.ai free for 2 weeks, then pick the one that fits your workflow. In code: try Cursor Hobby for 2 weeks, then Copilot free. The decision should be based on your real workflow, not features. The best AI tool is the one you actually use daily, not the one with the most features.
The most common AI stack mistake: subscribing to 3 writing tools, 2 image tools, and 2 code tools. The result: you don't use any of them well. Pick one per category, master it, and only add another if the first one fails. The exception: when tools specialize in different tasks. For example, Midjourney for hero images and DALL-E for quick sketches. Different tools for different jobs, not the same job from multiple tools.
Upgrade when: you hit rate limits weekly, you find yourself wishing for a feature, you save 1+ hours per week using the tool, or you start using it for work. Downgrade when: you only use it monthly, you have multiple tools doing the same job, or the free tier is enough for 80% of your needs. Remember: pay for tools that save you time, not for tools that look cool. If a $20/mo tool saves you 5 hours per month, that's $4/hour. a bargain. If it doesn't save time, it's $20 wasted.
For $0/mo: ChatGPT free, Claude.ai free, Microsoft Copilot free, Bing Image Creator free, Google Colab free for AI coding, Hugging Face free, Perplexity free 5 queries/day, Otter free 300 min/month, Canva free, Trello free, Notion free. The downside: rate limits, no API access, less support. The upside: $0/mo. For most personal users, this is enough. Upgrade only when you hit a real wall.
Don't take someone else's stack as gospel. saas.pet/find has 700+ tools. Filter by your use case. Test 2-3 per category for a week. The 5 that survive your real workflow for 30 days are your stack. The rest are distractions. The goal: a stack you actually use daily, not the most expensive or most popular. A $0 stack you use daily beats a $200 stack you forget about.
I built my personal AI stack over 6 months for saas.pet management. The standout combinations were ChatGPT Plus for writing, Cursor for coding, and Notion for documentation. The total cost was 73/mo for 1 person. The main limitation: feature overlap means I am paying for capabilities I do not fully use. I simplified to ChatGPT Plus + Cursor for now and will add more tools as I identify gaps. The stack covers 80% of my AI needs.
