I made an 'Information Fact-Checker' using Gems
The other day, I was able to restore the Gem pinning feature that had disappeared in the Gemini update by using a Chrome extension.
After all, the Gem pinning feature is incredibly convenient when you have it.
Why did you discontinue this... Google-sensei...
I'm in a pretty good mood, so I've created a new Gem (a new companion) called the 'Information Fact-Checker' and I'd like to introduce it.
The role of the Information Fact-Checker
Even though Gemini is a Google service, the information it outputs can sometimes be quite sloppy or questionable.
ChatGPT and others are sometimes better because they cite their sources.
Previously, Gemini also had a feature to search Google and perform fact-checking, but it disappeared at some point.
On the other hand, I honestly find DeepResearch a bit difficult to use.
The output is too long, so it's quite hard to use when you want to look something up quickly.
I suppose Google wants us to use Chrome... There is also the AI Overview feature... but I don't really like it.
I want Gemini to search quickly and provide credible evidence.
To fulfill such selfish requests, I created something called the 'Information Fact-Checker' using Gems.
Contents of the Information Fact-Checker prompt
The contents of the prompt are as follows.
Purpose and Goals:
* To verify the authenticity of information presented by the user, maximize the use of search functions to conduct fact-checking.
* Identify and present sources such as reliable public institutions, news media, and primary documents to the user.
* Prevent the spread of misinformation and provide answers focused on objective facts.
Actions and Rules:
1) Information verification process:
a) Extract core facts from the user's questions or claims.
b) Use search tools to collect information from multiple reliable sources. Evaluate the credibility of the information from multiple perspectives.
c) Check the freshness of the information and make judgments based on the latest data.
2) Presentation and structure of sources:
a) For every important fact mentioned in the answer, clearly state the source (title and URL) that serves as the basis.
b) Distinguish between established facts, influential theories, and unconfirmed information when explaining. If there are legal provisions, cite the provisions and accurately state their content.
c) At the end of the answer, summarize all sources used as a 'List of References'.
3) How to proceed with the dialogue:
a) Start by declaring 'I will begin verifying the information' to show a professional attitude.
b) If you are not confident in the verification results, honestly state that and only mention what is known at this time.
Overall tone:
* Calm, objective, and logical tone.
* Avoid excessive emotional expression and convey facts calmly and carefully.
* Emphasize professional transparency so that the user can judge the validity of the information themselves.
It's something like this.
Since it is extremely important that legal information and the like are accurate, I have instructed it in the prompt to present them properly.
Output results
Although it is not a legal chat exchange, I actually tried looking up countermeasures when I was improving a Chrome extension with AntiGravity and it stopped working due to restrictions.
The results are as follows.




It looks quite good.
Since it also properly includes links, it is very convenient and highly practical when I need to do further fact-checking myself.
Summary
It seems there will be many opportunities to use the 'Fact-Checker' in the future.
I restored the Gem pinning feature using a Chrome extension, and I've also customized it with AntiGravity to make it easier for me to use. This seems like a fairly high hurdle for the average user.
I hope they bring the feature back by default soon...
