How Much Are You Spending on AI Tools?

The 2026 AI tool market has exploded with quality options — but subscription costs have grown accordingly. ChatGPT Plus ($20/month), Claude Pro ($20/month), Midjourney ($10+/month), Perplexity Pro ($20/month), Canva Pro (~$13/month), Notion AI (+$10), Adobe Firefly (within Creative Cloud)... subscribing to all of these exceeds $80-100 monthly.

The problem is almost no one actually uses all these tools. Many people pay for subscriptions they barely use, while simultaneously missing tools that would genuinely boost their efficiency. The key is selectively subscribing to tools matched to your side hustle type.

This optimizer asks three things: What side hustle are you doing (or want to start)? What's your monthly AI tool budget? What tools are you currently using? With these inputs, it categorizes tools into 'must have,' 'nice to have but optional,' and 'don't need right now' for your specific situation.

Essential AI Tool Stacks by Side Hustle Type

① Blog/Writing: Core — ChatGPT Plus OR Claude Pro (one, not both), Perplexity Free or Pro. Optional — Grammarly Pro (for English writing). Budget 50K KRW: ChatGPT Plus (~26K KRW) + Perplexity Free is enough. No need to subscribe to both LLMs. ② Design/Image work: Core — Midjourney ($10+), Canva Pro. Optional — Adobe Firefly (if you have Creative Cloud). Budget 50K KRW: Midjourney Basic ($10) + Canva Pro ($13) = ~30K KRW. Use remaining budget for pay-per-use services like remove.bg.

③ Video/YouTube: Core — Descript or CapCut Pro (auto-captions, editing), RunwayML or Pika (AI video, if needed). Budget 50K KRW: CapCut Pro (~$8) + free tiers for everything else. ④ Coding/Automation: Core — GitHub Copilot ($10/month), Claude Pro OR ChatGPT Plus (code review). Budget 50K KRW: GitHub Copilot + one of Claude/ChatGPT. Not both.

⑤ Social Media/Marketing Content: Core — Canva Pro (design + scheduling), ChatGPT Free (caption generation). Optional — Buffer or Later (scheduling). Budget 50K KRW: Canva Pro (~17K KRW) covers most needs. ChatGPT free tier is sufficient. Most cost-efficient combination.

ChatGPT vs Claude: Do You Really Need Both Paid?

The most common question. Bottom line: one paid subscription is enough for most people. The two tools have different strengths — the right choice depends on your primary use case.

ChatGPT Plus (GPT-4o) wins when: you need various plugins/GPTs, image generation (DALL-E) matters, code execution and data analysis are needed, or Bing search integration is important. Claude Pro wins when: you need long document processing (100K token context), writing quality is paramount, code generation quality matters, or you need nuanced Korean language writing. Need both? Only if you're heavily switching between them daily.

Perplexity AI paid is valuable for frequent SEO content creators and those writing newsletters or reports requiring current information. Occasional use? Free tier is fine. Midjourney paid only makes sense when image sales or design work is your primary income. For casual use, Adobe Firefly free (just needs an Adobe account) is a solid substitute.

Recommended AI Tool Setups by Budget

Free to 10K KRW: ChatGPT free, Perplexity free, Canva free, Google Gemini free, Copilot (Microsoft account) — this combination supports most basic side hustles. Start with a fully free setup, then invest once income starts flowing.

20K-50K KRW: Above free tools + ChatGPT Plus OR Claude Pro (choose based on side hustle). Writing-focused → Claude Pro; multimedia-focused → ChatGPT Plus. This setup meets most AI side hustle efficiency requirements. 50K-100K KRW: Above setup + 1 specialized tool for your niche. Design work → Midjourney Basic; video work → CapCut Pro; SEO writing → Perplexity Pro.

100K+ KRW/month: Full professional tool stack becomes viable — but only if monthly revenue exceeds 300K-500K KRW. Tool costs should stay under 20% of income to make business sense. Subscribing to tools before generating income is wasteful. The right sequence: generate income first, then reinvest in tools.

FAQ

Is side hustle possible with free tools only?

Yes! ChatGPT free + Canva free + Perplexity free enables writing, design, and SEO research. Start free, then reinvest in paid tools once income flows — that's the smart sequence.

Which tool offers the best value for money?

For writing side hustles, ChatGPT Plus ($20) offers the best ROI. For design work, Canva Pro ($13). If choosing just one, invest in the core tool that directly serves your primary side hustle type.

Can AI tool subscription costs be tax-deductible?

With a registered business entity, yes — as software/business expenses. Once your side hustle income reaches a meaningful level, registering a business entity can be advantageous for tax purposes. Check with a tax advisor or your country's tax authority.
