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.
Boya Uday Kumar - 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 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."
"There is a significant return on investment, with a reported four times productivity increase on research and coding tasks that I do daily."
"I would rate my overall experience with Google Gemini as a nine out of ten."
"The most beneficial aspect of Google Gemini for me is that it's able to do searches much better."
"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."
"Google Gemini uses all the data that Google has produced."
"Google Gemini has the best combination of scalability, costs, performance, and accuracy."
"Google provides an out-of-the-box solution with a comprehensive ecosystem of tools, where everything is fine-tuned, and Google offers a comprehensive package that includes compute, networking, and data storage, allowing me to manage any kind of workload out of the box."
 

Cons

"The product is often extremely slow, and queries frequently fail due to system overload."
"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."
"When I have reached out to Google Support, it's been very limiting. I would rate Google at about a five."
"The code generation capabilities in Gemini could be improved."
"Sometimes there is some difficulty while understanding the issue and the technical jargon, but otherwise it is all good."
"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."
"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."
"Google can improve in model justification and interpretability of answers. I still perceive Google Gemini, in some instances, as a kind of black box."
"The only drawback for Gemini services or Google Vertex AI platform is that their platform understanding and getting started with the platform is a difficult process."
