Best Free AI Tools to Try in 2025 (With Examples + Prompts)

Don’t sleep on these AI tools — they can save you time on real tasks. These are perfect for content creators, students, marketers, or just someone who wants to get things done faster.

1. AI Writer

The AI Writer tool can give you a first draft you need to move forward. It works for blog posts, newsletters, social media posts, and landing pages.

How to use it:

  1. Choose the format
  2. How long you would like the text to be
  3. Select a language — there are 50+ options 
  4. Pick a tone that matches your idea.

In the chat area, tell it what you want to write about, such as: Write a blog post losing weight by walking 10,000 steps a day.

Done — the AI will generate a text following your instructions.

2. AI Paraphraser

What if a sentence or paragraph that you got from the AI Writer doesn’t sound quite like you want it to?

There’s a very easy fix. The AI Paraphraser helps you reword your content — not just by swapping synonyms, but by actually rewriting it with new flow.

For example, I’m not in love with this intro:

“In a world where quick fixes and fad diets dominate the conversation about weight loss, it’s easy to overlook the simple yet profound impact of walking.”

A bit wishy-washy for my liking, so let’s open the AI paraphraser on Overchat AI:

“In a world obsessed with quick fixes and fad diets, we often forget the powerful benefits of simply walking.” — sounds much better to me.

Prompt example: Paraphrase this to make it more punchy and shorter: [insert paragraph]

3. AI Image Generator

Sometimes you need visuals. While stock photos are fine, it takes a lot of time to find a good image, and even then they look cheesy. Instead of searching stock images, you can generate a custom image with AI, which is way more fun.

Since in the example we’re writing about losing weight by walking 10,000 steps a day, we could generate an image of a guy enjoying a walk.

A person wearing a backpack walks along a sunlit park path in the early morning or late afternoon.
Generate images like this in Overchat AI

Prompt example: Generate a realistic image of a person walking in a park, bright and positive, 8k, ultra-realism, detailed, real-life, lens flare.

This could be used as a blog header image, social media post, or even a cover image for Pinterest.

4. AI Question Answerer

Instead of digging through Google search results, use this tool to get straight-to-the-point answers from AI — it works for research, but also if you’re curious about tech, science, history, or anything else.

The difference here is focus: You ask a specific question, and it gives you a structured, readable answer — often more digestible than a full article or thread.

Overchat AI provides a detailed explanation of how walking 10,000 steps a day helps with fat burning, focusing on caloric expenditure.

5. Free AI Chatbot

This one doesn’t have any specific niche, rather, you can ask it anything in the form of a chat. For example — ask for feedback about what you’re doing, or brainstorm together:

Sometimes you need a free AI assistant

Bottom line

These AI tools are genuinely useful — and free for you to try.  Whether you’re trying to write better, learn faster, or get text out of a weird image, these tools save serious time.

Each one is worth exploring — and the best way to get a feel is to run real prompts and review the results yourself.
