Malte Landwehr - PeerSpot reviewer
Vice President, Seo at idealo Internet GmbH
Experience frequent delays and privacy concerns with current research tool
I advise not to use the web interface or the mobile app. If you think you should use it, use the self-hosted version. I gave DeepSeek a rating of 3 out of 10 because the core product, when it works, is actually good. But so often it's not working that I just can't give it a higher score.
Uday Boya - PeerSpot reviewer
AI Research Enthusiast and Developer at ADP
AI workflows have transformed prototyping and coding productivity across my daily projects
There is a steeper learning curve for advanced agentic features that could be improved, and hallucinations should be reduced. The answers provided are long, which is impressive but not efficient for users needing rapid, crisp responses. Providing concise answers would improve the user experience. Google Gemini AI's UI code is too vague and the designs are not very appealing. Google Gemini AI can improve its UI code and address hallucination issues. The long answers provided can be tiresome to read, and the pricing is too high for individuals like me. These considerations led me to give a rating one point less than ten. Native GitHub or Vercel export could be integrated, and the context could be increased to over two million tokens. A simplified agentic setup for the UI could also help non-technical experts handle it more effectively.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"DeepSeek makes its reasoning traces public."
"The most valuable feature of Google Gemini for us is its text writing capabilities, which we are using for writing texts and social media posts for our company's social media page."
"Recently, Google Gemini has been very stable, without performance issues, even handling network problems smoothly with a retry."
"The best features for my use cases with Google Gemini are its dynamic LLM model that can perform dynamic searches, which is wonderful for factual searches to understand numbers and to generate real-time answers."
"The most valuable feature of Google Gemini for us is its text writing capabilities, which we are using for writing texts and social media posts for our company's social media page."
"There is a significant return on investment, with a reported four times productivity increase on research and coding tasks that I do daily."
"I have compared responses from Gemini and ChatGPT and received similar results but presented differently, and every tool has its uniqueness; it is good, and I am enjoying using both tools, but most often I use ChatGPT because I haven't used Gemini recently."
"Google Gemini uses all the data that Google has produced."
"The main purpose of using the solution is to enhance internal activity and productivity, and I have seen many cases of reduced costs and working hours."
 

Cons

"The product is often extremely slow, and queries frequently fail due to system overload."
"Google Gemini could improve its functionalities compared to other tools like ChatGPT, especially in the customization options, Canvas mode, and web search tools, which aren't as advanced."
"I do not have a special recommendation for improvement."
"Sometimes there is some difficulty while understanding the issue and the technical jargon, but otherwise it is all good."
"When I have reached out to Google Support, it's been very limiting. I would rate Google at about a five."
"Google can improve in model justification and interpretability of answers. I still perceive Google Gemini, in some instances, as a kind of black box."
"Gemini 3 Pro is too expensive for individuals like me, costing about thirty dollars per user per month, and its responses tend to be long, requiring users to read considerably more than other models that provide crisper answers."
"Google Gemini could improve its functionalities compared to other tools like ChatGPT, especially in the customization options, Canvas mode, and web search tools, which aren't as advanced."
"Sometimes Google Gemini could hallucinate and provide incorrect information, which needs explanation for correction."
