About this appAI proposal
Dropwatch Den tracks the products you want across the shops you use. Paste a link, set the price you would pay, and get a notification when any store reaches it. No more reloading product pages or bookmarking items you forget.
It is made for online shoppers who want control over their data. Your watchlist is private by default and can be exported at any time. The hosted version is for people who would rather not run a server.
Unlike one retailer's own price-drop alert, it follows the same item across stores and keeps each price's history, so you can tell a real deal from a temporary markup.
- Tagline
- Name your price. We'll watch the shops.

- Why this name
- A den is a quiet, private place; drop is what you wait for in a price. Two plain words that say what it does.
In the first version
Members say which features they would use. It tells PWAS what people want; it changes no score.

What it could be worthEstimate
What a software business making this much sells for today, from real deals. Pick a monthly revenue.
If it makes
Worth about
$194,000
Sale range $132,000 to $263,000
$120,000 a year in revenue
From 87 software businesses listed and sold on Empire Flippers in the last year, revenue vetted by the broker: they sell for about 19× their monthly revenue, most between 13× and 26×.
Measured on profit, the middle deal is 32× monthly net profit: about 2.7 years of profit.
An estimate, not an offer or financial advice. A real price depends on profit, growth, churn, how much of the work is the owner's, and the buyer.
How it would growAI proposal
How the product would reach new customers through its own use, and how the first ones would be found. A plan to test, not a result.
- Built-in loop
- Shared outputs. Users send read-only watchlist links for gifts or group buys. Recipients see current prices and the tool's name, and can copy items to their own list.
- Do they become customers?
- Recipients can become users by copying an item. Test how many link openers sign up and track at least one item.
- First customers
- Privacy-minded online shoppers who already follow self-hosting and deal-hunting communities and track gear in one category, such as coffee or outdoor equipment.
- Where to reach them
- Self-hosting communities: Share a free hosted trial and the export-first design in forums and subreddits about self-hosting.
- Deal-hunting forums: Post price-history charts for popular items with a link to track them.
- First milestone
- Fifty weekly active free users and ten paying Plus users from one community within 60 days.

RisksAI inference
- TechnicalRetailer pages change often and use bot protection, so price parsers may break and need steady upkeep.
- PlatformSome shops forbid automated access in their terms, and may block the fetcher's addresses.
- CommercialFree open-source tools exist. Users may prefer self-hosting over paying for a hosted version.
- DataWrong or stale prices would trigger false alerts and quickly erode trust.
