The 5 Types of AI Tools You Actually Need

You Don't Need Them All

The AI tool market has exploded — from a few hundred products in 2023 to tens of thousands today. Most are just wrappers around the same underlying models with different UIs. The trap is subscribing to many tools while mastering none.

The right approach: identify your highest-frequency needs, master one tool deeply, then expand from there. Most people need only 3-4 tools total.

Type 1: Conversational AI (The Core)

If you could only use one type of AI tool, this is it. Conversational AI handles writing, research, analysis, Q&A, coding, translation, and summarization — essentially anything text-related.

Key tools: ChatGPT (GPT-4o), Claude (Anthropic), Kimi, DeepSeek, Wenxin Yiyan, Tongyi Qianwen.

How to choose: For users in China without VPN, Kimi, DeepSeek, and Wenxin Yiyan are free and work well for Chinese-language tasks. For maximum capability, Claude excels at writing and reasoning while ChatGPT is stronger for real-time search.

Free vs paid: Free tiers are sufficient for most users starting out. Paid plans (~$20/month) are worth it if you're hitting rate limits daily or need the most capable models for professional work.

Type 2: AI Search Engines

Traditional search gives you links to click through. AI search synthesizes information and gives you direct answers with citations — dramatically faster for research tasks.

Key tools: Perplexity AI (best overall), ChatGPT Search (requires Plus), Metaso (metaso.cn — free, China-accessible).

Best use cases: Industry research, fact-checking, understanding new topics quickly, competitive analysis. Always verify specific numbers by checking the cited sources.

Type 3: AI Image Generation

Generate marketing visuals, presentation graphics, product concept images, and social media assets from text descriptions — in seconds, without a designer.

Key tools: Midjourney (highest quality, $10+/month), DALL-E 3 (built into ChatGPT Plus), Jimeng by ByteDance (free tier, China-accessible), Tongyi Wanxiang (free tier).

Limitation to know: AI images often have issues with text in images (garbled), hand/finger details, and precise style control. Great for inspiration and quick assets, not always suitable for high-stakes branding.

Type 4: Video & Audio AI

Includes video generation, AI voice, automatic captions, and meeting transcription. Higher barrier to entry, but highly valuable in specific use cases.

Key tools: Runway (video generation), Sora (OpenAI, requires Plus), CapCut/Jianying AI (editing with AI captions, free), iFLYTEK Tingjian (meeting transcription, best for China).

Recommendation: Most people can skip this category initially. Exception: if you have frequent meetings, a meeting transcription tool delivers immediate ROI.

Type 5: AI Automation Tools

Connect different apps and automate repetitive workflows — no coding required for most use cases.

Key tools: Zapier (most integrations, $20+/month), Make (more flexible, $9+/month), Coze by ByteDance (free, China-accessible, good for building AI agents).

When you need this: When you catch yourself doing the same task manually every day. Set it up once, save hours every week going forward.

Starter Kit Recommendation

Zero-cost starter (no VPN needed): Kimi or DeepSeek + Metaso Search. Covers 80% of daily needs, completely free.

Power user setup (~$20-40/month): Claude Pro or ChatGPT Plus + Perplexity free tier + Jimeng for images. This combination covers 95% of professional AI needs.

Real Comparison Cases

Case 1 — Writing a payment reminder email: Both Wenxin Yiyan and ChatGPT produce usable output. The key difference is that ChatGPT tends to add more interpersonal nuance (offering the client a face-saving explanation), while Wenxin Yiyan produces cleaner, more template-like structure. Neither is objectively better — choose based on your relationship with the recipient.

Case 2 — Industry research: A Baidu search for "2024 cross-border e-commerce trends" required opening 7 links and 20 minutes to gather 3-4 data points. Perplexity answered the same question in under 2 minutes with cited sources and a structured synthesis. For research tasks, AI search is 5-10x faster.

The power combination: Use AI search to build a macro understanding of a topic, then use a conversational AI to go deeper on the specific aspects relevant to your situation. This two-step workflow beats any single tool.
