Artificial intelligence (AI) is making everyday work faster and easier. In 2025, many freemium AI tools help us write, plan, and organize tasks. These tools feel like smart helpers or robot assistants. For example, ChatGPT is a chatbot that can answer questions, help write stories or emails, and brainstorm ideas. Perplexity is an AI research assistant that goes way beyond a normal search engine. And tools like Grammarly check your writing so you make fewer mistakes. All these AI apps are helping shape the future of work by boosting productivity and saving time.
Below are seven top AI tools (with free plans) that are widely used in 2025. They work for general productivity – from writing and research to scheduling and automations. We list their main uses and links to their official sites, plus a quick comparison table at the end.
1. ChatGPT (OpenAI) – AI Chatbot for Writing & Ideas
ChatGPT is like a robot friend that talks and writes. You type a question or idea, and it answers or writes text for you. It can help with homework, tell jokes, or even draft emails. The latest version can also generate images and take voice inputs. Best of all, ChatGPT is free to use in its basic form. Just start a chat and it will “help with writing, learning, brainstorming, and more.” People use ChatGPT to generate ideas, translate languages, or get quick research. A paid “Plus” subscription offers additional features, though the free plan remains highly functional.
- What it does: Chatting to answer questions, write drafts or code, explain ideas.

Think of it as your personal AI research buddy. Whether you’re looking up facts for school, trying to learn something new, or researching a project, Perplexity helps you find the right info fast. And it does this using real-time web data, not just old stuff like some other AI tools.
Perplexity is free to use and works right from your browser. If you want extra features like faster answers, deeper research tools, and access to premium AI models like GPT-4.1 and Claude 4, there’s a paid Pro version too. But for most people, the free version is more than enough for daily use.
