The 7 Best Free AI Tools You Should Be Using in 2025 (And a Smarter Way to Use Them)

Introduction

Let’s be honest, AI tools are no longer a novelty. In 2025, they’re either your productivity edge or the reason you’re falling behind. I’ve tested dozens of them, and while most promise everything, only a few actually deliver real, measurable results.

Recently, I watched a breakdown of the 7 best free AI tools on YouTube, and it got me thinking: it’s not about which tool is “best”—it’s about how you use them together. Whether you're running a business, building content, or just trying to make better use of your time, these tools can change your workflow forever.

Here’s the smarter way to use them—and how I’m building similar (but better unified) features into Crompt AI.

1. Zapier: Automate Everything, Even Your Creativity

Zapier is a behind-the-scenes genius. It connects over 6,000 apps so you can create automated workflows without writing a single line of code. Want to post your newsletter to Twitter, Slack, and Notion simultaneously? Done.

But automation only works when you have clarity on what to automate. That’s where AI-enhanced planning tools like our Task Prioritizer come in. Before you start automating, figure out what’s actually worth your time.

2. Google AI Studio: Embedded Intelligence

Google’s new AI capabilities inside Gmail, Docs, and Sheets feel like a silent productivity coach. It completes your sentences, drafts replies, and suggests content structure. Think of it as autocomplete on steroids.

However, what it gains in convenience, it lacks in deep customization. For instance, if you're crafting client proposals, I prefer using the Email Assistant inside Crompt—it understands tone, format, and business context better because it's trained specifically for that use case.

3. ChatGPT: The Classic That Keeps Evolving

Of course, ChatGPT is still the backbone of many AI-powered workflows. From brainstorming to coding, it remains versatile and sharp. But switching tabs between use cases—one for writing, another for summarizing, another for marketing copy—kills flow.

That’s why Crompt is built to let you do all of that in one place. You don’t need to jump between models. Just choose a tool like the Content Writer or Rewrite Text Assistant, and you're good to go.

4. Udio: AI-Powered Song Creation

If you’re a creator, Udio is magic. It lets you generate entire songs with lyrics and melody in seconds. Use it for podcasts, branding, or that birthday jingle you forgot to plan.

While Crompt isn’t a music generator yet, our AI Caption Generator helps creators stay consistent by pairing visuals with impactful text that resonates across platforms.

5. ElevenLabs: Your AI Voice, Perfected

AI-generated voices that sound human are here—and ElevenLabs is leading that charge. From narrating YouTube videos to creating audiobooks or training modules, this tool is redefining accessibility.

If you’re using voice for storytelling, it’s smart to pair it with solid scriptwriting. I use the AI Script Writer in Crompt to draft compelling scripts that sound natural when spoken aloud.

6. Perplexity AI: Research With Receipts

Perplexity AI is like Google if it could think. It doesn’t just show you links—it synthesizes information, cites its sources, and gives you a deeper answer.

It reminds me a lot of how we built our Research Paper Summarizer. The goal is the same: help you learn faster, with context, clarity, and credibility.

7. Descript: Edit Audio & Video Like a Doc

Descript lets you edit a podcast the way you’d edit a Word doc—delete the word, delete the sound. It’s a dream for content creators, video editors, and marketers.

But here’s the real trick: combine that with AI-generated content upstream. Plan your content using the AI Caption Generator, write your script with the Script Writer, and then drop it into Descript for editing. That’s a full-stack workflow with minimal friction.

Why These Tools Matter More Than Ever in 2025

• You can’t afford to work slowly. Every other team is using these tools or something like them.

• Siloed apps kill flow. That’s why we’re building everything into one seamless interface at Crompt.

• It’s not about knowing the tools. It’s about stacking them smartly.

You don’t need 50 tools—you need five that work together. And ideally, you want them in one place, guided by your goals, not scattered tabs.

Crompt’s Vision: One AI Hub. Every Tool You Need.

Most AI startups are just wrappers around ChatGPT. Crompt is different. We’re building a model-agnostic platform that brings the best tools for business, content, learning, and life into a single, elegant space.

Whether you need to write, summarize, plan, analyze, or just get unstuck—there’s a Crompt tool made for that. And no, you don’t need to “train it.” You just show up.

TL;DR (Because We’re All Busy)

• The 7 AI tools from the video are legit.

• You should be using them. But don’t use them in isolation.

• Tools are only powerful when you stack them smartly.

• Crompt AI puts the whole stack in one place—no switching tabs, no lost time.
