The analysis of existing tools and why they are annoying is spot on, no one is paying for it, so existing solutions try to recoupe 4.57$ monthly revenue from ads.

But that means that the product you are launching is trying to undercut 4.57$/mo for 0$/mo, which is a losing proposition. Any proposition that tries to undercut a market that has already been driven to bottom prices will die of hunger.

Also, in terms of execution, there's a design choice "recent lookups" that is quite unconventional, and will kill the trust of your product, and your personal reputation.

By leaking your user's input and data, you have outed yourself as someone that cannot be trusted with user or commercial data.

You have died twice, first from hunger and then from reputational death. I am in a better position for having launched nothing than you are in for launching this.
