AI tools are leveling up with deep research, enabling expert-level analysis in minutes.
Table of Contents Artificial intelligence brands are in fierce competition, and their next steps are to make their AI tools smarter by allowing them to execute deep search functions that can provide expert-level results and analyze larger amounts of information in a shorter time. Several companies have announced deep research features in recent weeks and months, which excel in areas such as finance, science, marketing, and academics.
As per pundits’ reviews, Gemini’s deep research is known to provide detailed results, referencing several sources across the internet. Depending on the topic, the tool can reference upwards of 50 sources when conducting its research and save the results in a Google Docs file. Because of its depth of research, results tend to be detailed and lengthy. Reviewers have noted that collecting information for podcast episodes are among some of the practical use cases.
Perplexity AI deep research Perplexity AI announced its deep research tool in February 2025, in a unique fashion with a free tier available at launch. This helped the brand stand out at a time when rival AI brands had their deep research features strictly behind paywalls– however, it would quickly urge companies to begin experimenting with their own free options.
Grok 3 deep search The Grok 3 deep search tool was announced in February 2025 alongside its accompanying Grok 3 AI model, with tech CEO, Elon Musk claiming that the model outperformed rival models, including Gemini 2.0, GPT-4o, DeepSeek-V3, and o3 mini. Similar to Perplexity’s deep research tool, Musk called Grok 3 deep search a “next generation search engine.” While the tool was available for free for a short time after its announcement, it is mainly accessible through a paid subscription.
