I'm a bit ashamed to admit, but I don't really understand how I would use this.
I've looked at your youtube channel, can I suggest you do a walkthrough with voice of your best customer use case and make it clear why this is of value?
I think you may be onto something, but I'm just missing that last bit of connection to make me go "I NEED THIS!!"
Also, your pricing is confusing. As someone who has run a company with confusing pricing before, this is a HUGE issue. You really need to simplify it. For our company, our costs were complicated and annoying because we had large service costs, (map data) and free accounts with tons of use could easily bankrupt us. Your cost structure shouldn't be challenging like that, so you should be able to simplify the pricing.
Things like 24 synced cells sounds incredibly small if I'm basically sharing my spreadsheet with notion. But maybe this is clearer when the user has a better idea of how they'd use your tool.
I always like pricing where I'm reluctant to pay, but feel I'll get so much value, that I don't really have a choice.
With your pricing at $15/month for 24 synced cells, I feel like I'm being asked to pay for a lot, and not getting much in return.
