📝 Tool Breakdowns

1. ChatGPT Free (OpenAI)

💡 Use it for everyday AI tasks — from writing help to explanations. You currently can't beat ChatGPT, it is useful for just about anything and is pretty much your free assistant!

ChatGPT is the most popular AI chatbot in the world, and its free version (GPT-3.5) is still incredibly versatile. You can use it to brainstorm ideas, write drafts, answer questions, or explain complex topics in simple terms. The only downside is that it’s not as powerful as GPT-4, but for most tasks, the free version is more than enough.

2. Perplexity AI

💡 Use it as a smarter, AI-powered alternative to Google Search.

Perplexity AI combines the power of chat with reliable sources. It doesn’t just answer your questions — it provides citations so you know where the info came from. This makes it excellent for research, fact-checking, and studying. The free plan is generous, and it’s one of the most trusted AI tools for accuracy.

⭐ Rating: 90/100

3. Canva AI Tools

💡 Use it to design graphics, social media posts, and logos instantly. It's very beginner friendly and has been a very useful tool for me to design graphics for personalised gifts on Etsy.

Canva is already a favourite for design, and its free AI tools make it even more powerful. With Magic Write, you can generate text for posts, while Magic Design and Text-to-Image help you create visuals in seconds. Some premium features are locked behind Pro, but the free plan is still packed with value.

⭐ Rating: 85/100

4. Runway Gen-2

💡 Use it to turn text prompts into experimental video clips. Perfect for faceless YouTube shorts & such like.

Runway Gen-2 is one of the most exciting free AI video generators. You type in a description, and it creates short AI-generated videos. It’s still early-stage tech, but fun to experiment with if you’re a creator. The free plan gives you credits each month, though they run out quickly if you use it a lot.

⭐ Rating: 75/100

5. Poe by Quora

💡 Use it to test multiple AI chatbots in one place.

Poe acts like an all-in-one AI platform, letting you try out models like Claude, GPT-3.5, Llama, and others — all for free. It’s great if you want to compare how different AIs respond to the same question. Daily limits exist, but it’s a fantastic way to explore the AI landscape without paying.
