What's the story behind your product?

ChatFalso's answer

ChatFalso was born out of frustration. The creator makes TikTok content that uses fake WhatsApp conversations and was spending 20-30 minutes per chat building them manually in Figma. Every existing tool online was either full of ads, required payment to remove watermarks, or was missing key features like link previews. So they built ChatFalso to solve their own problem and decided to share it for free with anyone who needs it.

Diffyn's answer:

I started working on Diffyn when I notice that prompting has become an essential part of work across many industries. While there are version control platofrms like github, they are not designed for just prompt management are can be overkill such applications, it is also not integrated natively with various LLMs and relevant tools for users to validate ideas and visualise results properly.

Who are some of the biggest customers of your product?

ChatFalso's answer

  • TikTok creators making POV and storytime content
  • YouTube creators producing skits and comedy videos
  • Instagram creators making Reels with fake chat screenshots
  • Educators teaching about misinformation and digital literacy
  • Marketers creating social media mockups and presentations
  • Meme creators
