If you’re curious how to turn a simple idea into a polished video without hiring a crew or learning complex software, you’re in the right place. Today I’m sharing 8 free AI video generator online tools you have to try today, tools that let you craft content from simple text prompts, add visuals, voice-overs, subtitles and more. Whether you’re making social posts, tutorials, or just experimenting, these make video creation far easier than ever.
Why use an AI video generator online?
An “AI Video Generator Online” is just what it sounds like: a web-tool where you type in what you want (your idea or script), and the system helps you turn that into a video, often generating visuals, matching voiceover, adding music or subtitles too. For example, the brand-name platform Invideo lets you generate AI videos from simple text prompts. Prompt your video idea and our AI video generator writes the script, adds visuals generated with AI, adds voiceovers, subtitles, music, etc. This means you don’t need advanced video editing skills or expensive software. Just your idea, a prompt, and away you go.
What you should look for
When you test these tools, keep an eye on things like:
- How easy it is to go from idea → video prompt
- Whether you can edit or refine the result after generation
- Export options (resolution, watermark, formats)
- Cost of the free plan vs what upgrades you might need
- Whether the output truly fits your style or looks generic
Now let’s dive into free AI video generator online tools you should try today. I’ll list each, what makes it good, and how you might use it.
1. Invideo
This is the one of the best ai video generator, I mentioned up front. The tool by Invideo is designed specifically so that from a text prompt you can let the system write the script, generate visuals, voiceover, subtitles, music.
Why it stands out:
- Very beginner-friendly.
- The workflow is clear: prompt → generate → edit → publish.
- Good for lots of types of content (social media, tutorials, marketing).
How you might use it: Suppose you have a blog article and you want a short video version for Instagram. You plug in “Make a 60-second video about X” and pick voice, visuals, etc.
Tip: On the free plan you’ll likely get limitations (watermark, lower resolution). Still great for testing the concept.
2. Kapwing
Another strong choice. Their “AI Video Generator” converts text to video, with image-to-video also available.
Why it stands out:
- More freedom to edit after generation (B-roll, subtitles, voiceover, etc).
- Good for creators who want more control.
How to use it: You might write a short script like “Explainer: how to tie a tie” and then let Kapwing generate a video, then tweak it (change timing, add your brand logo).
Tip: Explore editing features, generation is just the start.
3. Adobe Firefly (AI Video Generator)
Adobe Firefly offers an “AI video generator” that turns text or images into videos.
Why it stands out:
- Backed by Adobe, so likely good visual quality.

HeyGen is focused on text to video or image to video with templates and avatars.
Why it stands out:

Renderforest offers an AI video generator that turns scripts into visuals with templates.
Why it stands out:
- Good for template-based workflow (less from-scratch design).
- If you want a quicker turnaround, this helps.

7. Steve AI
Steve AI is another text-to-video tool that offers multi-style output, voiceovers, script generation.
Why it stands out:

How to use it: Write a prompt like “Kids story: friendly robot helps with homework” and let Steve AI generate visual style + narration + scene ideas.
Tip: Make sure you adjust scenes so they match the pace you want; automated tools sometimes get timing off.
8. Pixlr Video Generator
Pixlr (primarily known for image editing) also offers a “video generator” where you can create HD videos from text or images online.
Why it stands out:
- If you already know Pixlr for image work, this helps keep everything in one ecosystem.
- Good for product showcases, tutorials, social posts.
How to use it: Upload an image + type prompt, or start purely from text, then get a video you can export.

How to pick the right one for you
- If you’re totally new: go with Invideo or HeyGen, they are simple to use.
- If you want more control and editing: Kapwing or VEED.io.
- If you want stronger visuals or product animations: Adobe Firefly or Steve AI.
- If you rely on templates and quick turnarounds: Renderforest or Pixlr.
Pro tips to get better results
- Write a clear prompt. Think: “Create a 60-second video about how to bake sourdough bread for beginners, friendly tone, visuals of hands mixing dough, finished loaf, cheerful music.” The more specific you are, the better the AI output.
- Review the script the tool generates. Many of these tools will auto-generate a script from your prompt. Tweak it to make it sound like you.
- Edit the visuals. Don’t accept the first output blindly. Change shots, adjust timing, ensure branding is correct.
- Mind the voiceover and subtitles. Good tools let you specify voice type, accent, language; also edit subtitles so they are accurate.
- Check export settings. Free plans may limit resolution or have watermarks. Make sure it fits where you’ll publish (YouTube, Instagram, etc).
- Use consistent branding. Add your logo, colors, font so the video still feels like yours, not just a generic AI product.
- Experiment. Try different styles, prompt variations, lengths. Some tools are better for short videos (10-30 seconds), others for longer ones.
- Factor in time and cost. “Free” often means limited credits, watermarks, or lower resolution. Decide when you might upgrade.
