Hey Product Hunters!

We're excited to share StepFun Diligence Check with you today! This has been a passion project born from our daily frustration with information chaos online! Think of it as your personal fact-checking assistant. Just paste links, long texts, AI responses, and any content you find dubious. We'll verify it for you.

Here's what makes us different:

  • Multi-source verification: We don't just search — we check claims against multiple trusted sources for the most reliable fact-checking

  • Real-time analysis: Fresh information pulled from current sources, not yesterday's news

  • AI-powered validation: Multiple specialized agents work together to spot dubious sources, flawed logic, and missing context

We're not here to tell you what to believe. Instead, we give you the tools and evidence to cut through information overload and make informed decisions yourself.

🎯 Perfect For

  • Journalists who need quick source verification

  • Researchers tired of manual fact-checking

  • Anyone who wants to avoid misinformation

  • Teams building content that needs to be bulletproof

I am testing it on the question I had last week and had to research because I was uncertain, and the internet was full of contradictory information (it took me ~30 minutes to get some conclusion)... I tried Stepfun and have it in less than 10 seconds :D My Substack newsletter will be written faster now.

Love that you thought about everything in advance (e.g. generating an image of the convo, sharing it via link or QR code).

I am attaching my generated screenshot.

Just out of curiosity, what made you choose Discord as the sign-in platform? :D :)

Tommy Wang

@busmark_w_nika Thanks for your support Nika! Considering everyone's preferences, we offer three login options: Discord login, Google login, and email registration/login. The Discord login option is included because we have a Discord community, which makes it easier for everyone to communicate, discuss, and provide feedback :)

Congratulations on the launch. StepFun Diligence Check delivers a timely and much-needed solution for professionals seeking accurate, real-time verification in an age of digital misinformation.

StepFun Diligence Check sounds like a game-changer for researchers! 🧐 The real-time analysis and multi-source verification are impressive. How do you ensure the credibility of the sources your AI agents use?

Tommy Wang

@jaredl Thanks for your great question!

We’ve teamed up with industry experts to curate a list of high-authority sources. Our multi-agent system then independently assesses the credibility of these sites, factoring in things like their nature and popularity. It also cross-checks information with multiple sources to spot differences in authority and trustworthiness.

Additionally, we go the extra mile by looking for official sources to verify data and ensure there’s no misuse.

Thank you for the vision and support!
We’re committed to maintaining the highest standards of accuracy! 😊

Abdul Rehman

Just gave StepFun Diligence Check a try! I love the concept and how it tackles misinformation head-on. The multi-source verification is definitely something that sets it apart. The interface could be a bit more intuitive, especially when pasting longer texts. I found myself wondering if I did it right or if it was still processing.

Excellent work, team!

Tommy Wang

@abod_rehman Thank you for trying out StepFun Diligence Check and sharing such detailed feedback!


Making the processing status more intuitive and transparent is one of our highest-priority user-experience improvements, and it’s already on our near-term roadmap.

Stay tuned for our updates! ❤️

CaiCai

The official website design looks very comfortable, congratulations on the launch. But I'm very confused, is this recommendation of yours serious? "How to quickly marry a billionaire"

Tommy Wang

@hi_caicai Thanks for the support and feedback! You're absolutely right to point that out. It looks like we had a user-shared case displayed by default (users can share cases they find interesting), but that particular example doesn't reflect the right values we want to promote. We'll definitely adjust the visibility of that type of content. Really appreciate you bringing this to our attention!

Launching soon!

What is the pricing? Also, can you give me some use cases?
(Btw, congrats on the launch!)

Cruise Chen

It seems indeed a very useful tool in age of Agentic product.... Just curious, how is the accuracy so far and what is the pass rate?

Tommy Wang

@cruise_chen Thanks for your attention!
We invited a group of human experts to compare several fact-checking agents, including GenSpark, Felo, GPT-o3, GPT-4o, and Gemini 2.5pro. In this evaluation, our StepFun Diligence Check achieved a pass rate over 60%, ranking first among all the tools. We're continuing to work on improving accuracy to make it even better!

Really appreciate the support!

Anthony Latona

This looks super helpful for anyone doing REAL research; especially for any esoteric topics. Since AI can totally make things up, having the citations is very important. I was doing some research on non-profit fundraising rules & regulations and it was tough to decern what was real and what might have been hallucinations...

Anyway... congrats on the launch!

Tommy Wang

@anthony_latona Exactly! Those niche topics like non-profit regulations are where hallucinations can really hurt - you need to know what's actually true when compliance is on the line.

Thanks for the support!

August Zhu

The multi - agent verification and real - time analysis of Stepfun Diligence Check are so needed in this era of info overload! For users dealing with highly specialized, niche topics, how does the tool ensure it can access and verify reliable sources within those specific domains?

@nanqun_chen Congrats on the launch! Good luck!!
