About this appAI proposal
Rooknote turns your own chess games into short, spoken lessons. After a game, it walks you through the moments that decided it, explains the idea behind each mistake in plain language, and then sets you the same position to practice.
It is for learners at any level who find free tools too technical and paid platforms too costly for what they give. The aim is a clean, fast interface that is pleasant to use every day, with a price that fits a hobby.
Where free tools stop at evaluation numbers, Rooknote explains why a move failed and what to look for next time. Courses use the same narrated format, so reviewing and studying feel like one habit.

- Why this name
- A rook is a chess piece, and a note is what a good coach leaves in the margin. Two plain words that say the product explains your games.

PricingAI proposal
The material gives no competitor prices, only that paid platforms are seen as overpriced. These tiers are a starting point to test, aimed below what learners call poor value.

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. Learners send a narrated review link to a friend, coach or forum thread. The recipient can play through the game and hear the key moments without an account.
- Do they become customers?
- Recipients are often chess players too and could sign up to review their own games, but a link opened once brings no customer by itself. Test how many viewers import a game of their own.
- First customers
- Adult club-level improvers who play online and want to get better, are unhappy with subscription prices, and already review games on their own.
- Where to reach them
- Chess forums and subreddits: Post free narrated reviews of well-known amateur games and invite readers to submit their own.
- Chess video creators: Offer small coaches and streamers free accounts to review viewers' games and share the links.
- Local chess clubs: Run a review night where members bring games and get narrated reviews on the spot.
- First milestone
- Fifty free users review three or more games each, and ten of them pay for the Learner plan within two months.
Why people already pay for this
- AI inferenceChess.com offers narrated game reviews that appeal to learners, but the platform's interface is inferior and not worth its subscription price.
- AI inferenceThere is demand from chess learners willing to pay for courses that provide better learning experiences.
- AI inferenceExisting paid chess platforms fail to offer sufficiently better products to justify their prices.

RisksAI inference
- AIGenerated explanations may be wrong or vague about why a move fails. Needs engine-grounded checks and human-written templates for common themes, and testing with real players.
- CommercialLearners may stay with the free platform if narration feels like a small gain. Willingness to pay at a lower price is only inferred from comments and must be tested.
- PlatformImporting games from other sites depends on their export options and terms, which could change or limit access.
- Intellectual propertyCourse content must be original. Copying lessons or voice styles from existing paid platforms would invite claims.
- TechnicalRunning engine analysis on low-end phones can be slow, so some reviews may need server-side processing.
