1. Generate Realistic Images – Sora

Sora is OpenAI’s image generator. You can simply give the model a text prompt to generate an image for you, or even provide a reference image to guide it.

With Sora’s free version, you can generate a maximum of two photos at a time, and you can prompt it for revisions as many times as you like until you get it right.

2. Audio Translator for Short Form Videos – YarnGPT

YarnGPT is an AI-powered translator specifically for Nigerian indigenous languages. You can use the ‘Video translate’ feature to translate languages spoken in videos into three major languages: Hausa, Yoruba, or Igbo. Currently, this feature is in beta mode and supports files up to 100 MB and 10 minutes in length.

To demo this, I uploaded a snippet of an animated documentary that was originally in English (complete with music and sound effects) and asked it to dub the video into Yoruba. It took roughly five minutes to process.

Use cases: Content creators and entrepreneurs can use YarnGPT to create social media video voiceovers in Yoruba, Hausa, and Igbo to reach a much wider audience.

3. Keep Your Grammar Tight and Consistent – LanguageTool

LanguageTool is an AI-powered grammar checker that helps you maintain consistency across your written pieces. While it does have a paid version, the free tier works perfectly as a basic writing editor. It detects errors while you write, suggests revisions, and even shows you different ways to paraphrase your sentences.

SerenDPT is an AI study companion designed to convert your texts into speech that you can actually engage with.

To demo the app, I took a CV drafted by Google’s AI model, Gemini, put it into the system, and asked it to read it back to me. SerenDPT also gave me the option to talk to the AI. Although it has different pricing tiers, the starter plan gives you one reader voice, allows you to input 5,000 words a month, and gives you 30 Q&A prompts.

Use cases: The features of SerenDPT are set up in a way that it can become a study partner, a tutor, or a reading buddy you can actually have a conversation with.

Important Update: “Must-Have” Tools for 2025 (That You Can’t Miss) Apart from the original list, if you are looking for 10 free AI tools worth trying in 2025, ignoring these two tools would be a mistake.

For Real-time Search – Perplexity AI: If you are tired of Googling and scrolling and just want a direct answer, try Perplexity. It is a conversational search engine. Instead of giving you links, it gives you a direct answer and cites its sources so you can verify them.
For Research and Writing – Claude 3.5 Sonnet: If you feel ChatGPT’s writing sounds a bit robotic, give Claude a shot. Its free version (Sonnet) is incredibly sharp at human-like writing and coding. In 2025, this is being considered the best free tool for students and writers.

5. Generate Flashcards – Google NotebookLM

Google’s Notebook LLM allows you to create flashcards from a set of information. To use this feature, simply create a new notebook and upload your sources.

When prompting NotebookLM, you can set the difficulty level of the flashcards. Once the cards are generated, if you need more information, you can click ‘Explain’ on each flashcard so the AI can give you a deeper explanation.

6. Visualize Reports – Google’s NotebookLM

With Google’s Notebook LLM, you can input a data set and visualize it using the ‘Mind Map’ function. To demo this, I inputted an AI-generated CV into the notebook. Then, I asked the notebook to condense the information into a mind map. The notebook will generate results based strictly on the sources you feed it.

Use cases: With Notebook LLM, data visualization can be incredibly helpful when you want to represent large pieces of information, reports, or study materials clearly.

7. Build Presentation Decks in a Few Words – Gamma App

If you need to visualize data or prepare for a presentation in the least amount of time possible, Gamma is built exactly for that. You can generate an AI-designed deck of slides with just a one-line prompt. With the free plan, you can make a maximum of 10 slides per deck. After that, you can ask Gamma to create illustrations, find stock photos, or even upload your own images.

I asked Gamma to generate a deck from Deshtak Moonshot 2025 conference YouTube trailer, and left it on the default setting to create its own 2D illustrations. This web app also gives you the flexibility to prompt an image for every single slide in the deck.

8. Smart Recipe Extraction – Yescheff

With Yescheff, you can extract all your favorite recipes directly from YouTube videos.
