Sinceerily ironic.

I think / hope this is purely satirical, because I have no idea what else I am supposed to take from this: Hi, I'm Ben. I got sick of everyone in my inbox sounding like AI. So I built Sinceerly. I tested Sinceerly by cold emailing 5 Fortune 500 CEOs. 4 CEOs replied. Of those replies, each was under 10 words. 2 replies had typos. One reply called me Larry (my name is Ben). LMK what you think.

Like the icon. Like the name. Like the concept. Not something I would pay to use, but I'm sure this would be useful to others. Wish you luck.

I don't hate this idea. The core premise being that I want an easy way to tune the tone/personality of how a model talks to me and generates content. It's definitely possible to tune but it's not obvious for most users. Pretty easy feature for the model providers to add.

I think AI is a good tool but we need to face up to how a high number of AI applications are about enabling people to lie to each other more effectively.

I wrapped model around a system prompt. Spent more time making the website. 5 bucks a month. So what, everyone seems to be doing that

It is ironic how AI is rapidly swinging the pendulum from “corp speak” to “typo filled drafts” in an attempt to look human. But AI to make your hand written messages “look human” is just a cash grab. This has to be like 8 hours worth of vibe coding or less.

the collective em dash hallucination is so goofy, i hope it is at least fun for the folks plagued with it. the em dash is a normal thing people use, and DEFINITELY a thing that pre-AI grammar checks enforced! i generally use -- when i write (no idea where i got it from); google docs has converted this to — forever. like literally since V1.0, and i don't even think you can turn it off. feels super fun to get bonus points leaving my (totally technically incorrect) --s intact though

I have never had an experience with AI writing where I didn't have to essentially re-write the entire document. It's excuciating. I've about given up on it.

Your easy to use slider looks like a good tool for general users. Have you considered expanding it beyond email to include longer-form content?
