The instinct, faced with a dozen shiny AI products, is to subscribe to a few of them. You rarely need to. Most of what people pay for is available free, and in the places where paying genuinely helps, a few dollars stretches a long way. Here is how to cover writing, coding, images and research with AI for as little as possible. All prices were checked against each vendor’s own page in August 2026.
How we costed this
By "free" we mean a genuine, ongoing free tier, not a trial that expires. Figures are in US dollars and can vary by region. Paying is worth it only when a free limit actually gets in your way.
The free stack that covers most people
For writing, coding, images and research, you can pay nothing and still do real work.
- Writing and everyday chat: ChatGPT, Claude or Gemini, all free.
- Coding help: GitHub Copilot’s free tier or Cursor’s free Hobby plan.
- Images: DALL-E free inside ChatGPT and Microsoft Copilot, or Canva’s generous free plan.
- Research with sources: Perplexity’s free tier, or NotebookLM, also free, for your own documents.
For a large number of people, that is the entire stack, and it costs nothing. The paid plans mostly raise limits and add convenience rather than doing things the free tiers cannot.
If you pay for one thing, make it count
The moment to pay is when a free limit actually blocks you. The best value is a single low-cost plan that stretches across several jobs. These are the cheapest meaningful upgrades right now.
| Tool | Price | Best for |
|---|---|---|
| Gemini (Google AI Plus) | $4.99/mo | Higher limits across writing, research and Google apps |
| ChatGPT (Go) | $5/mo | More headroom for writing, images and everyday use |
| GitHub Copilot (Pro) | $10/mo | Serious daily coding |
| Midjourney (Basic) | $10/mo | The best image quality, since it has no free tier |
| Grammarly (Pro) | $12/mo | Dedicated writing and editing |
| Canva (Pro) | $15/mo | Design and brand assets at scale |
Notice the two cheapest. Gemini AI Plus at $4.99 and ChatGPT Go at $5 each stretch across several tasks at once, which is exactly why a single one of them is the most cost-effective upgrade for most people who outgrow the free tiers.
Three stacks, by budget
Pick the one that matches how much you actually lean on AI.
- The $0 stack, for most people: free ChatGPT or Claude, Copilot’s free tier, DALL-E inside ChatGPT, and Perplexity for research. Total, nothing.
- The $5 stack, one upgrade: keep all of the above free, and add either Gemini AI Plus at $4.99 or ChatGPT Go at $5 for more headroom across several tasks.
- The $15 maker stack: GitHub Copilot Pro at $10 for real coding, plus Gemini AI Plus at $4.99 for everything else. Swap in Canva Pro if your work is design-heavy.
The catch
Two caveats. Free tiers come with usage caps and fewer features, so a heavy day can hit a wall that the paid plans remove. And AI pricing moves constantly, the numbers here were verified in August 2026, so confirm on the vendor’s own page before you commit.

Not to start. GitHub Copilot and Cursor both have free tiers. GitHub Copilot Pro at $10 a month is the step up for heavy daily coding.
