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."
"Google Gemini uses all the data that Google has produced."
"The most beneficial aspect of Google Gemini for me is that it's able to do searches much better."
"Recently, Google Gemini has been very stable, without performance issues, even handling network problems smoothly with a retry."
"The main benefits that Gemini brings to the table include definitely speeding things up significantly, and it is also introducing many new use cases that we were not able to work on earlier."
"I'm impressed with its orchestration capabilities, which structure the workflow for research automatically and meaningfully, making it a helpful tool."
"I would rate my overall experience with Google Gemini as a nine out of ten."
"Google Gemini has the best combination of scalability, costs, performance, and accuracy."
"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."
"I do not have a special recommendation for improvement."
"Google Gemini often gets factual answers wrong, which is problematic."
"Sometimes Google Gemini could hallucinate and provide incorrect information, which needs explanation for correction."
"Google Gemini needs more accurate answers and the ability to export data to Excel or Google Sheets."
"Google can improve in model justification and interpretability of answers."
"I conducted some research using Google Gemini, and sometimes the results are not correct. For example, when I asked for information about marketing and inquired about the sources used, the sources were not relevant or had no relation to the subject I was researching."
"When I have reached out to Google Support, it's been very limiting. I would rate Google at about a five."
"Currently, it operates mostly autonomously, and while it provides structured activities, making the research configuration more accessible and flexible would be beneficial."
