Featured Reviews

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.

Tool proves competitive with cost-effectiveness and speed while benefiting decision-making and integration capabilities, but shows room for enhancing creativity and handling large data contextually
There is another benefit in that Google Gemini is highly competitive from a cost perspective. The cost per token is very competitive. It's not the best - the Chinese models such as DeepSeek are better, but I can't use them. From a cost perspective, between European and United States options, Google Gemini is very competitive. It's not only its cost, it's also very performing. The time it takes to process the prompts and context information is very fast. It's one of the fastest models in the market. That's another advantage. There are other models which are also very good in quality but not as fast, such as Anthropic Claude. Google Gemini currently has a very good balance. The AI capabilities of Google Gemini are a multi-modal LLM which allows me to pass documents, images, and texts in the same prompt. Being multi-modal makes my life easier. I don't have to translate information before I can work with it. Google provides free tools to test scenarios, which speeds up development and reduces costs. It's a very fast and accurate model with quality responses.

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."
"The integration of Gemini with other Google services is quite good; we develop the application using open source platforms such as LangGraph or LangChain, where the integration for Gemini is quite good."
"Google Gemini AI is better in terms of searching the web, considering that Google Gemini AI is a property of Google, and the search results when looking for answers from the web are superior compared to those given by Alexa."
"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 have seen many cases of reduced costs and working hours."
"I would rate my overall experience with Google Gemini as a nine out of ten."
"Google provides an out-of-the-box solution with a comprehensive ecosystem of tools."
"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."
 

Cons

"The product is often extremely slow, and queries frequently fail due to system overload."
"I do not have a special recommendation for improvement."
"There are scalability issues, and they are all related to what you can do within that context window of a million tokens."
"Google Gemini needs more accurate answers and the ability to export data to Excel or Google Sheets."
"Sometimes Google Gemini could hallucinate and provide incorrect information, which needs explanation for correction."
"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."
"When I have reached out to Google Support, it's been very limiting. I would rate Google at about a five."
"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."
