I read the accuracy report and I'm yet to find on what basis is your accuracy score being built on. Is it the number of personas that re-post, like, comment, see, all of the above?

I think you guys might be onto something but I'm still skeptic as to whether you are the most accurate (on whatever metric). It's not surprising that you beat a survey of experts, or straight out of the box commercial LLMs.

I'm more interested in seeing how your model performs against purpose specific models that are currently industry standard. Unless you're making the claim that you're the first service to predict content engagement?

Would love a link to the demo if and when you’re open to sharing. I’m a product designer but not looking for projects, I’m mostly curious - this is one of the more unique ideas I’ve heard.

Yea, let me send it your way once I have it! Please update your profile with contact info.

Interesting! I built something similar at a hackathon a while back: https://fnands.com/blog/2024/factory-hackathon/

We called it Journalaist, and billed it as a personal ghostwriter. What we found is that it lives or dies by the quality of the interview

Thanks for sharing! Yes, I quickly came to that conclusion as well. It's put me in the novel position whereby product development is about finding the right prompt, and maybe even about finetuning.

Have you heard of https://www.autobiographer.com/ ? Is it similar, different?
rollinDyno · a month ago
It's pretty much the same, but I have a few ideas to make my app stand out. Thanks for sharing! Nice to see the idea has potential.

Have you ever wanted to write your life story but found it too overwhelming? I’m developing an app that acts as your personal interviewer, guiding you through your memories and helping you share them with your loved ones.

The app is designed for older adults who enjoy reminiscing but struggle to organize their thoughts into a coherent narrative. The goal is to preserve their hard-won insights and pass them down—to family members who may be too busy to ask the right questions now, and to future generations who would otherwise never hear these stories.

I have a working prototype that allows me to test the interview flow, and I’ll soon be sharing it with friends and family for initial feedback. I’m now looking for a designer to collaborate on the next phase.

Design will be a critical part of this app. The way stories are visually presented will be central to the user experience and will likely determine the app’s success. If you’re a designer interested in this kind of work, I’d love to hear from you. Given the text-heavy nature of the app, experience with typography and content-focused design will be especially valuable.

https://inlovingmem.com/ - is a tribute to my recently deceased mom that I vibe coded over the last week. I felt her life deserved to be celebrated widely but wanted to be sensitive to her privacy. I've also built in a number of interactive features for participation in funeral services etc, before, during, and after.

Folks have reached out about having an 'In Loving Memory Of' site for their loved ones, so I'm turning this into a side business to help out more with my (now widowed) father's retirement and care.

Hej, I made FisherLoop[1] to learn Swedish. FisherLoop are interactive audiobooks where I use TTS with word level timestamps to highlight the words as they are spoken. This helps me pick up on pronounciation and grammar in a, for me, natural way. Additionally, I added flashcards from the books + word lookup. I am adding new books right now. If you have any requests: public domain books, which are around one hour reading time let me know :)

I am using cerebras for book translations and verb extraction and all LLM related tasks. For TTS I am using cartesia. I have played around with Elevenlabs and they have slightly natural sounding TTS but their pricing is too steep for this project. Books would cost a couple of hundred euros to process.

I'm interested but I'm not getting the confirmation email.

I recently finished my PhD studies in social sciences. Even though it did not lead me to career improvements as I initially expected, I am happy I had the opportunity to undertake an academic endeavor before LLMs became cheap and ubiquitous.

I bring up my studies because what the author is talking about strikes me as not having been ambitious enough in his thinking. If you prompt current LLMs with your idea and find the generated arguments and reasoning satisfactory, then you aren't really being rigorous or you're not having big enough ideas.

I say this confidently because my studies showed me not only the methods in finding and contrasting evidence around any given issue, but also how much more there is to learn about the universe. So, if you're being rigorous enough to look at implications of your theories, finding datapoints that speak to your conclusions and find that your question has been answered, then your idea is too small for what the state of knowledge is in 2025.
