A receipt-scanning expense tracker with item-level bill splitting for friend groups

Target User

Young professionals and friend groups who split restaurant bills and shared expenses

Product Idea

A mobile app: snap a receipt → AI extracts line items → tap to assign each item to a person → generates Venmo/PayPal request links. Doubles as a personal expense tracker.

Evidence

• “"People were tired of manually logging every expense. They wanted something that just reads the receipt and does the work for them" (https://www.reddit.com/r/SideProject/comments/1rx2a4x/why_do_i_have_to_type_everything_manually_so_i/)”

• “"The item-based bill splitting is such a good idea. Splitting evenly always felt unfair when someone just had a drink" (https://www.reddit.com/r/SideProject/comments/1rx2a4x/why_do_i_have_to_type_everything_manually_so_i/)”

Why this opportunity matters

This opportunity surfaced from Reddit where Young professionals and friend groups who split restaurant bills and shared expenses are actively describing the problem in their own words. We classified the demand intensity as medium — meaning the problem is consistent enough that multiple users are searching for a fix, even if they have not committed to paying yet. When users self-select to post a problem on a public platform like Reddit, they are usually already trying to solve it — which makes them strong candidates for the right paid alternative.

How to validate this before you build

Before writing a single line of code, three lightweight steps will tell you whether this opportunity is worth pursuing:

1. Read the original conversation. The evidence links above lead to the exact threads where users described this problem in their own words. Read every comment — what people argue about in the replies often matters more than the original post.
2. Talk to five real users. Find five people who match the target user description above and ask how they handle this today. You are looking for two signals: a consistent workaround they hate, and a willingness to pay for something better. If both show up in three of five conversations, the demand is real.
3. Test willingness to pay before building. Put up a one-page landing site describing the proposed product, with a deposit or pre-order checkout. If even a small fraction of traffic converts to a real payment, you have validated more than most products that ship to production.
