AI search tools PK, the three knowledge search god who is the strongest?Perplexity, Secret Tower, Felo depth comparison

Are you still using Baidu to search for information? It's too inefficient!

In the age of information explosion, the ability to accurately obtain the information you need has become a scarce ability. The first step in improving your search capabilities is to change your search engine!

Traditional search engines are not only full of advertisements and complicated information, but also inefficient, making it difficult for you to judge the authenticity of what you're searching for.

The advent of AI search solves these problems perfectly. Just type in a question and it will provide you with refined results and all the information is traceable and accurate, it really smells great!

Today, we're going to take a look at three of the hottest products in the AI search scene right now: Perplexity, Secret Tower AI Search, and Felo. which one is the best? Let's take a look.

Perplexity

Perplexity Unlike traditional search engines, it is the world's first LLM-based conversational search tool designed to provide accurate and comprehensive information. the godfather of AI, Jen-Hsun Huang, revealed that it is the search engine he uses every day. So what's so great about it? Let's explore it together!

Intelligent understanding and precise answers

Imagine you have a super-smart friend who quickly understands and gives clear answers every time you ask him a question.

Perplexity plays this role, when you use it for searching, instead of giving you a bunch of links and ads like traditional search engines, it really understands your needs and provides you with clear and concise answers that are source-based and accurate.

in-depth conversation

Not only does Perplexity specialize in integrating the vast amount of information available online to give accurate, comprehensive answers, but it also has an ongoing dialog with you.

你可以一直向它”提出后续问题”，让你不断深入探索。更贴心的是，它还会主动提供相关问题，帮你挖掘你可能没想到的角度。

滑动搜索框右边的”pro”选项，还能调用GPT-4、Claude-3等高级模型。

Free users get 5 chances per day, so if you have deep search needs, consider subscribing to the Pro version, which not only allows you to choose your favorite model, but also allows you to analyze unlimited text!

Focused search and additional

Perplexity also has two super cool features: Focus and Attach.

There are a total of 6 modes under the Focus option. Users can not only search across the Internet, but also focus on specific sources of information.

For example, when you select the Academic mode, it searches directly for content related to academic papers.

The Attach function is like your multimedia assistant. Not only can you search the web, but you can also upload files and images to assist in your search.

In addition to this, Perplexity has interesting features on the left side such as Library and Discover for you to explore, which I won't go into too much detail here as they are non-search core features.

All in all, Perplexity is a super-smart search tool that can greatly improve your access to information, so it's worth a try!

Secret Tower AI Search

Secret Tower AI Search It is a domestic AI search engine launched by Secreta Technology. In the era of Perplexity alone, the secret tower AI quietly into the AI search track, attracting industry attention, and become a domestic AI search dark horse. After in-depth experience, we have to sigh: secret tower AI search really something!

Smart search, simple and efficient

When you open the home page of Secreta AI, its Slogan is obvious: no ads, straight to the results!

Just like its Slogan, its product philosophy is pure, direct and efficient.

Below the search box you can choose between concise and in-depth modes.

The concise mode provides citation information and summaries, while the in-depth mode unfolds key information in more detail.

Unlike Perplexity, Secreta AI also intelligently generates outlines and mind maps on the right side of search results to help users quickly build a knowledge framework.

Not only that, Secreta AI also offers assisted search functions, including full web, library, academic and podcast modes. These options appear directly above the search results for easy switching.

For further questions, there is also a follow up question function at the bottom right of the search results.

Intelligent information grooming

Secreta AI's deep search is a master of information organization.

A table is automatically generated below the search results in three main categories:

• Related events
• Related organizations
• person of interest

The small funnel filter next to the table header is even more thoughtful, allowing users to filter by different types, easily targeting the type of information of interest and further understanding of the search topic.

Source of information

Similar to Perplexity, Secreta AI Search provides sources of information.

It not only marks the cited sources with corner notation, but also summarizes all the source links at the end, so that users can understand the main reference sources more intuitively. It is worth noting that most of its cited articles come from Chinese websites and Chinese literature.

To summarize, Secreta AI Search is equally efficient and intelligent, more versatile than Perplexity in terms of information combing and logical summarization, and most importantly, it doesn't require magic!

Felo

Felo It's an AI search tool produced by Japanese company "Sparticle Corporation" (but rumor has it that it's a national team?). Sparticle is an AI search tool produced by a Japanese company "Sparticle Co.

Penetrating closed platforms

Felo came later and stood out even after Secreta dominated the minds of Chinese users, relying on a unique skill: searching for content from closed platforms such as Xiaohongshu and Reddit.

In today's cutthroat internet ecosystem, platforms are trying their best to lock users into their own ecosystems.

Felo, a rising star, breaks through ecological boundaries through browser extensions to provide users with an all-encompassing perspective.

Users have one-stop access to high-quality content that is hard to reach with traditional search engines through Felo.

Domestically, platforms such as Zhihu, WeChat and Xiaohongshu monopolize quality content; globally, X and Reddit are information centers.

For users thirsty for diverse perspectives, it is really good to have such a tool that can search closed platforms such as Little Red Book.

Cross-language search

Cross-language search is definitely a big part of Felo, after all, its Slogan is "Search the world in your language".

We tested it when we asked Felo in Chinese "What are the best places to visit in Kyoto?" it first looked up the Japanese source, extracted the information, and then translated it into Chinese.

Cross-language search is centered on accurately understanding user intent and retrieving relevant content globally.

对于”京都有哪些好玩的景点？”这类问题，本地人的视角最为珍贵。日本本土的旅游指南和博客，往往能提供最细致、最地道的建议。

在上述测试中，Felo 完美捕捉了用户需求，省去了查找和翻译的繁琐步骤，堪称”攻略党”的得力助手。

Management of information sources: users have the final say

Felo's source management is a treasure trove of features.

仍以上述”京都旅行”搜索为例，Felo提供了20个不同的信息来源。这里面可能会有“水分”，此时，用户可以轻松在Felo上筛选这些信源。

点击”查看”后，Felo会列出所有信源及其概述。

发现有不可靠的信源？一键点击”删除并重写回答”，Felo会根据剩余信源重新生成纯净版信息。

In this way, the user gets not ordinary answers, but carefully selected quality information, the examination party ecstasy!

Extensive model access

Felo currently has access to a total of six models, respectively, GPT-4o, Claude 3.5 Sonnet, Claude 3.5 Haiku, OpenAl o1-mini, Gemini 1.5 Pro and Llama 3.1 70B, the latter five models need to open the Pro in order to use, the free version of the default GPT-4o, the results are also very The free version defaults to GPT-4o, and the effect is also very good!

Diverse model support is also a feature of Felo; after all, many AI search tools force users to use their own models.

Overall, while Felo is not perfect, its features such as penetrating closed platforms with cross-language search do bring unique value to users.

summarize

The basic function of all three major AI search engines is to trace the origin of a question posed by a user and systematically organize the answers the user wants.

They each have their own characteristics, in general:

Secret Pagoda and Felo are more suitable for Chinese babies and can be easily used without magic. Among them, I personally think Felo is better, not only can it search closed platforms such as Xiaohongshu, but it is also able to cross-language search, cite sources in different countries, etc. It's really too treasure!

Perplexity is more aggregated with a global perspective, which is great for academic or more authoritative searches, but may not be as accurate as Secret Pagoda and Felo in processing Chinese information.
