40 Most Popular AI Tools Right Now: 2025 Edition

I couldn’t open Reddit, check Slack, or scroll through Twitter without someone dropping a link to yet another artificial intelligence (AI) tool.

“Have you tried this?” “It just dropped.” “It writes blog posts in your voice.” “It edits videos while you sleep.”

That’s not just anecdotal. The number of AI tool users is projected to reach 1.2 billion by 2031, and the market itself is expected to grow to $1.01 trillion, with an annual growth rate (CAGR 2025-2031) of 26.60%.

So, at some point, I stopped bookmarking and started tracking.

This list is the result: 40 of the most popular AI tools in 2025, pulled from search trends, G2 reviews, forum threads, and yes, my own ever-growing list of tools I’ve tested, used, or watched explode online.

Some are generative AI software category leaders. Some are niche but wildly loved. All of them are showing up again and again in the places where real AI conversations are happening.

If you want to see what people are actually using, start with the table below, or keep scrolling to explore by category.

10 most popular AI tools in 2025: At a glance

*This list pulls from search trends, G2 reviews, forum discussions, and tools I’ve personally tested. Web traffic data and popularity signals are backed by the sources listed at the end of this article.

Best AI tools I keep coming back to

If I’m being honest, building a “most popular AI tools” list in 2025 is a bit like trying to hit a moving target. What’s hot this month might fade away next month. So instead of ranking every tool definitively, I pulled together something more grounded, a snapshot of what people are actually using, sharing, and talking about right now.

The 40 tools that made this article passed a few key checks:

• G2 reviews and Grid Report leaders (top-right quadrant, thousands of reviews)
• Real usage data (monthly active users, install base, traffic)
• Search and community buzz (Reddit threads, Google Trends, “just found this” tweets)
• A mix of freemium and paid tools (because popularity ≠ free)

Out of those 40, many are still evolving: adding features, refining models, expanding into more use cases. But a few have already pulled ahead, carving out a clear lead in their category.

The 10 tools below stand out. They lead their categories (G2 Grid Report data supports this), show up in real workflows, and in most cases, I’ve used them myself. Here’s what makes each one worth a closer look.

1. Canva: Best for AI image generation

• User count: Over 220 million active users
• Monthly visits: Approximately 803.96 million visits 
• G2 rating: 4.7/5 (4,500+ reviews)

Its AI features are now packaged under Magic Studio, a suite that includes tools like Magic Design, Magic Write, and Magic Edit, enabling users to generate and customize designs effortlessly. 

With a user base of over 220 million monthly active users and a valuation of $49 billion, Canva is a dominant force in the design industry.
