What is PDF Insight?
PDF Insight is an AI tool that lets you chat with your PDF documents and pull out the insights you need without reading every page. Upload a PDF such as a research paper, report, contract, or manual, then ask questions in plain language and get answers grounded in the document's content. You can ask for summaries, key points, or specific facts and data, which makes it useful for students, researchers, and professionals who work with long documents. A free tier is available, so you can try it on your own files at no cost.

If you do a trial, it's actually a much longer payback period — what finance people call float — than a lot of people expect. We have a 30-day trial which is a bit much for a mobile app, but we do it. 30 days, the user subscribes, Apple pays you a month later. You end up with up to a 90-day float.
A 30-day trial is a 90-day cash float — Apple's payout delay starves you
Long trials look cheap on a paywall but starve cash flow. Greg's 30-day trial plus Apple's payout delay creates a ~90-day gap between ad spend and revenue — a critical input to whether paid acquisition is even viable while bootstrapped. Always compute the float before scaling spend.
sometimes customers say they will join if you build a particular feature if possible make them commit by paying for multi-month subscription with the guarantee that you built the feature within a reasonable time frame otherwise them telling you that they will sign up if you build this that's just an empty promise
Force "I'll sign up if you build X" prospects to pre-commit with a multi-month plan
"Build X and I'll sign up" is one of the most expensive lies in early product development — you build the feature, they don't convert, and you're stuck maintaining bloat for one phantom prospect. Convert the conversation: "I'll build X if you prepay 6 months at full price, refundable if I don't ship by date Y." Real prospects pre-commit; tire-kickers go quiet. Either way you stop building features for non-customers.
There's a play for whatever you're stuck on.
