My Personal Opinion About DeepSeek

I spent a week working with this new open-source AI tool and in the process I got a good idea of why it’s a strong contender in the field and where it still needs improvement. Here, I’m simply presenting its strengths and weaknesses based on my own experience.

What Makes This AI Tool Stand Out?

Great and Smooth Text Output

When I wrote a variety of articles and notes, the results were very clean, lively, and almost human-like. The biggest advantage was that each paragraph remained fluent, which saved me a lot of editing effort and time.

Great Grip on Difficult Prompts

I asked it to do everything from simple questions to complex tasks, and it did the job quickly and accurately almost every time. The best part was that I didn’t have to change or explain the prompts over and over again, which is often a problem with other tools.

Open Source and Free

The tool is open source, which means no hassle of expensive subscriptions or licensing. It’s highly customizable for developers, and for regular users, it offers a pro-level experience without the added expense. When everything else in the market is hidden behind a price tag, that’s a clear advantage.

A Vibrant Community and Constant Updates

The open source community of this tool is very active. Questions are answered immediately on the forums, and new features are constantly being added. This environment made my experience easy and efficient, and it was nice to know that an entire team is working on improving it every day.

Challenges Facing DeepSeek

Weak Grip on Specific and Technical Topics

While the tool performs well on general topics, when I asked it specific research or technical questions, the answers sometimes felt superficial or unclear. This may be a drawback for those who work in very specific fields.

Occasional Informational Errors

On a few occasions, the answers seemed to be on the surface correct, but when I checked them in depth, small errors emerged, such as outdated information or slight confusion. If you are working on sensitive or important information, it is best to double-check.

User Interface Could Be Improved

The interface is not bad, but it is definitely behind the best tools on the market. For example, a feature like dark mode would have been beneficial for long sessions, and there should have been a simpler way to handle different tasks. There should also be a clear help section for new users. These small changes can greatly improve the overall experience.

Pros and Cons

Clear, human-like text
Handles hard prompts easily
Free and open-source
Active community support
Great for general writing tasks

Weak on technical topics
Sometimes gives wrong info
Needs setup for full control
