I spent one month actually using the AI video generation tool "Pika." I started with the free plan, switched to a paid plan partway through, and put it to the test to see whether it's truly a useful tool.
What you'll learn in this article
It all started when I saw a video going viral on social media and learned it had been made with Pika. I was especially intrigued by a feature called Pikaffects — a physics-simulation feature that makes flames shoot out or objects melt when you tap an image.
There are other AI video generators out there, but three things sealed the deal for me with Pika. First, I could try it on the free plan. Second, everything runs entirely in the browser. And third, there was plenty of Japanese-language information available, making it easy to get started. Before using it for work, I just wanted to play around with it casually.
Honestly, my initial reaction was "this is harder than I expected." I assumed the AI would just automatically create something for me, but the quality of the resulting video varies enormously depending on how you write your prompt. For the first three days, no matter how many times I tried, I couldn't get the video to look the way I imagined.
That said, after a week I started to get the hang of it. The trick is to keep your instructions short and specific. Instead of just "a cat runs," writing something like "a white cat running through a meadow, sunny day, slow motion" gets you much closer to what you're picturing. Generation time is around 30 seconds to one minute per video — faster than I expected.
1. The free plan is genuinely usable
Even on the free plan, you get 30 credits per month (roughly 30 video generations). That's more than enough to give it a proper try. Credits reset every month, so you can learn at your own pace without feeling rushed. Commercial use isn't allowed, but for personal learning purposes it's perfectly fine.
2. Pikaffects is genuinely fun
This is Pika's flagship feature. Apply an effect to a still image and things start melting, exploding, or turning into cakes. It came in really handy for creating short videos for social media. It's a playful feature you won't find in other tools.
3. Full HD 1080p output
The latest model, Pika 2.5, lets you export video in full HD (1080p). The image quality holds up even for YouTube or presentation materials — noticeably sharper than earlier versions and genuinely at a practical level.
1. Video length is short
You can only generate up to 10 seconds at a time. If you want to create a longer explanatory video or something with a narrative arc, you'll need to stitch multiple clips together in post-production, which is a bit of a hassle. I'd love to see support for longer durations.
2. No commercial use on the free plan
The free plan is fine for personal enjoyment, but you'll need to subscribe to a paid plan (Standard or above) to use it for work. Monthly fees run roughly ¥3,000 for Standard and around ¥7,000 for Pro. When you're not sure you'll use it every month, that's a bit of a hesitation.
3. Japanese prompts don't perform as well
The tool officially supports Japanese, but writing prompts in English yields noticeably better results. With Japanese, my intent sometimes didn't come through clearly and I often had to regenerate multiple times. This could be a real hurdle for people who aren't comfortable with English.
I compared Pika with another AI video generator, Runway. Runway is geared toward more serious video production and comes packed with detailed editing features. Pika, on the other hand, is better suited to the use case of "I just want to quickly make a short video."
Runway supports longer video durations and finer adjustments, but the tradeoff is a more complex interface with a steeper learning curve. Pika is simple and intuitive, making it the better recommendation for anyone trying an AI video generator for the first time. Conversely, if you want to do serious video editing, you may find it falls short.

After a month of use, I came away feeling that Pika is the perfect tool for anyone who thinks "I just want to try making a video." It's not perfect, but you can get started for free with a low learning curve — so if you're curious, I'd recommend just diving in and giving it a try.
