Don't fancy racking up a big monthly bill with countless AI software subscriptions? No problem. You'll find plenty of excellent free AI tools to help you with proofreading, learning languages, and more.
1 Grammarly
While Grammarly is a fantastic tool for writers, you don't need to be a professional to reap its benefits. Grammarly's free version will catch typos and grammatical errors in your essays, emails, and social media posts.
You can copy and paste your text into the Grammarly web app, but integrating the tool with your browser is more efficient. Once you've done this, you can get real-time suggestions while you're writing. The extension is available in Chrome and Safari, as well as a keyboard app for mobile.
With the free version of Grammarly, you get a limited number of premium daily suggestions for improving your writing clarity.

2 Claude
Claude is a great ChatGPT alternative, and with the free version, you get access to its Sonnet model. Claude can solve math equations, write articles, and even generate code. You can change Claude's writing style from Normal to Explanatory, Concise, or Formal.
When using Claude, you get access to visualizations that can better explain concepts, equations, and theories when needed. Besides asking the software for various in-app prompts, you have the option to upload images if necessary.
You can ask the software to provide reasoning after it has generated something, which allows you to determine if your prompt needs changes. Claude lets you access all of your chats from the left-hand toolbar, and in addition to the web app, you can use the tool on iOS and Android.

3 Adobe Firefly
Adobe Firefly is one of the most photorealistic AI generators and is particularly fantastic for headshots. The Adobe Firefly app is incredibly straightforward, and even the most basic prompts can deliver excellent results.
Besides creating images that look like photos, Firefly can make artistic illustrations. It's not as good as GPT-4o (formerly DALL-E) for these, in my opinion -- but it's still a pretty solid option.
In 2025, Adobe introduced AI video generation to Firefly. When compared to Sora, it lags behind; nonetheless, you can create two videos for free, and it's worth trying. Firefly also has AI features in Adobe Express. You can upgrade to a paid plan if you wish, but the free version is good enough for most users.
4 Zapier
Are you tired of spending hours on manual tasks for your work or studies? If so, Zapier might be what you're looking for. The tool integrates with over 7,000 apps, including Google Drive, Notion, Outlook, and Gmail. It's one of the best email productivity tools and can help you in other areas of your life.
Many people make their own "Zaps" from scratch in Zapier, which involves building custom automations. For example, you can create folders, files from text, and shortcuts within your apps. The software lets you sign into your accounts using the Zapier interface.
In addition to generating your own automation from scratch, Zapier has an AI tool where you can add prompts. Doing so will eliminate even more of the manual work. Even with a free plan, you can generate unlimited Zaps and access AI power-ups.
5 LanguaTalk Close
You'll find a handful of AI-powered language-learning apps, and LanguaTalk is one of the best you can use for free. In essence, it works like ChatGPT but is specifically designed for learning a new language.
With LanguaTalk, you can type and chat with an AI character. It's possible to pick the difficulty level based on your current skills; if you're advanced, you can choose to have a conversation with lots of slang involved. The speaker goes at more of a natural pace, making it easier to jump into communicating with native speakers. If needed, you can slow down the voice.
LanguaTalk processes natural speaking, meaning you don't need to be perfect. If you don't understand something, you can always translate it into your native language.

6 Nerd AI
Nerd AI is a simple AI tool you can use to solve various problems and answer your questions. For example, you can calculate mean and median statistics -- in addition to solving trigonometry and various other mathematical problems.
You can use Nerd AI for history, languages, and a number of other topics at school. The app has a built-in calculator, too, and you can translate full texts with a dedicated tool. Moreover, you have the option to summarize books.
Besides prompting the software, you can upload a PDF of your homework and receive assistance. The app will help you with answers based on your question.

7 Removebg
Do you need to quickly remove the background for one of your images? No problem. Removebg is an easy-to-use editor with which you can do just that. You don't need to sign up for an account; instead, you just have to upload your picture. Within a few seconds, the software will delete the background.
For a free editor, the results are quite good. However, the software sometimes struggles with artifacts looking similar (like grass and fur). Once you've removed the background, you can replace it with something else if you want.
You can upgrade to a paid plan if you want; doing so will let you download higher-resolution images.
8 Leonardo.ai
Leonardo.ai is a simple art generator that rivals the likes of DALL-E. To make your image, you simply need to enter a prompt explaining what you want. You can choose between one and four pictures; each image you generate costs 10 credits. It's possible to select the aspect ratio you want for your pictures, too.
With a free Leonardo.ai plan, you receive 150 daily credits. Unless you want to create hundreds of pictures daily, you'll probably find this quota more than enough. When generating your art, you can choose the style you want, such as anime, watercolor, and stock photos.
There are so many free AI apps out there, and you can solve almost any problem without spending a single dollar. While many of these free AI apps offer a premium subscription, you don't really need to upgrade unless it's absolutely necessary.
