📊 Comparative table of the 4 tools
| Criterion | ChatGPT | Claude | Gemini | Perplexity |
|---|---|---|---|---|
| Writing | ⭐⭐⭐⭐ | ⭐⭐⭐⭐⭐ | ⭐⭐⭐ | ⭐⭐⭐ |
| Research/facts | ⭐⭐⭐ | ⭐⭐⭐ | ⭐⭐⭐⭐ | ⭐⭐⭐⭐⭐ |
| Long documents | ⭐⭐⭐ | ⭐⭐⭐⭐⭐ | ⭐⭐⭐⭐ | ⭐⭐ |
| Creativity | ⭐⭐⭐⭐⭐ | ⭐⭐⭐⭐ | ⭐⭐⭐ | ⭐⭐ |
| Images | ⭐⭐⭐⭐⭐ | ❌ | ⭐⭐⭐⭐ | ❌ |
| Code | ⭐⭐⭐⭐⭐ | ⭐⭐⭐⭐⭐ | ⭐⭐⭐⭐ | ⭐⭐ |
| Free | Limited | Limited | Generous | Generous |
| Pro price | $20/month | $20/month | $20/month | $20/month |
Our recommendation to get started: Start with ChatGPT (the most versatile) and Perplexity (for research). Test Claude when you need quality writing or to analyze long documents.
🛠️ No-code platforms to go further
The tools above are perfect for one-off interactions. But if you want to automate tasks or create workflows, you need no-code platforms.
OpenClaw: your personal AI agent
OpenClaw is a unique solution: a personal AI agent that you control from Telegram. No need to code — you talk to it in natural language and it executes.
What OpenClaw can do for you (no code):
- 📱 Answer your questions via Telegram, 24/7
- 📝 Write content (articles, posts, emails)
- 🌐 Search the web and summarize results
- 📊 Analyze files and data
- 🔄 Automate recurring tasks
- 🖼️ Analyze images you send it
How to start with OpenClaw:
- Ask someone technical to install it on a VPS (20 minutes)
- Configure it with your Telegram account
- Talk to it like a human assistant!
You: "Summarize this article: [URL]"
OpenClaw: "Here are the key points..."
You: "Write a LinkedIn post about 2025 AI trends"
OpenClaw: "Here are 3 versions..."
You: "Translate this text into English"
OpenClaw: "Here is the translation..."
Unique advantage: Unlike ChatGPT or Claude (limited to a conversation), OpenClaw is an agent — it can execute actions, access files, browse the web, and chain complex tasks automatically.
⚡ Zapier AI: connecting your apps
Zapier is the reference platform for connecting applications. With its AI features, it's even more powerful.
Examples of Zapier + AI automations:
- New email received → AI summarizes → Slack notification
- New blog post → AI generates social posts → auto-publishing
- Form filled → AI analyzes → personalized email response
- Twitter mention → AI evaluates sentiment → alert if negative
How it works:
- Trigger: An event triggers the workflow (email received, form filled...)
- AI action: Zapier sends the content to an LLM (integrated ChatGPT)
- Final action: The result is sent somewhere (email, Slack, Google Sheets...)
Price: Free up to 100 tasks/month. Paid plans from $19.99/month.
Limits: Zapier's integrated AI uses basic models. For quality, you need to connect your own API key.
Make (ex-Integromat): the visual alternative
Make is similar to Zapier but with a more powerful visual interface. You build your automations by connecting blocks like Legos.
Make's advantages over Zapier:
- More intuitive visual interface (drag & drop)
- More control over data flow
- Better value for money (more generous free plan)
- Native AI modules (OpenAI, Claude)
Concrete example: no-code content pipeline with Make:
[Google Sheets] → [AI module: generate article] → [AI module: SEO]
↓ ↓
[Notion: save] ← [AI module: translate EN] ←──┘
↓
[WordPress: publish as draft]
All this is built visually, without a single line of code.

✋ 5 things to do today
Enough theory. Here are 5 concrete actions you can achieve now, in less than 30 minutes each.
1. Create your account on the 4 free tools (10 min)
Open these 4 links and create a free account on each:
- ChatGPT: chat.openai.com
- Claude: claude.ai
- Gemini: gemini.google.com
- Perplexity: perplexity.ai
Why all 4? Each has its strengths. By testing them all, you'll know which one to use for what. It's like having 4 specialized assistants instead of one.
2. Ask the same question to the 4 tools (10 min)
Take a question that interests you and ask it to the 4 tools. Compare the answers.
Example questions to test:
- "Explain [subject from your field] as if I were 10"
- "What are the 2025 trends in [your sector]?"
- "Help me write an email for [concrete situation]"
You'll immediately see the differences in style, precision, and relevance. It's the best way to choose your favorite tool.
3. Have AI write a useful document (15 min)
Choose a document you really need to write and ask AI to help you:
- An important email you've been putting off
- A meeting summary
- A LinkedIn post for your profile
- A job description
- A project plan
The magic prompt:
You are an expert in [field]. Help me write [type of document].
Context: [explain the situation]
Desired tone: [professional/casual/formal]
Length: [short/medium/long]
Elements to include:
- [point 1]
- [point 2]
- [point 3]
Key tip: The more context you provide, the better the result. Don't just say "write an email", say "write a professional email to my manager asking for a raise, mentioning my 3 latest achievements: [X, Y, Z]".
4. Summarize a long document (10 min)
Find a long document you've never had time to read:
- A PDF report
- A 5000+ word article
- A contract
- Lecture notes
Upload it to Claude (best for long documents) and ask:
Summarize this document in:
1. 5 key points (2 sentences each)
2. Important numbers
3. Actions to retain
4. What might concern me directly as [your role]
Result: In 30 seconds, you'll have a structured summary of a document that would have taken you 1 hour to read.
5. Create your first "custom assistant" (15 min)
On ChatGPT, create a custom GPT (or use the "Custom instructions" feature):
Recommended custom instructions:
About me:
- I work as [your job]
- My sector is [your sector]
- I communicate in French
- My technical level is beginner
What I want:
- Clear and concrete answers
- Practical examples from my field
- No technical jargon without explanation
- A [professional/friendly/direct] tone
With these instructions, every conversation will be automatically adapted to your profile. No need to repeat the context each time.
