About this appAI proposal
Bare Buffer teaches you to build your own Emacs IDE from a vanilla install. You add one capability at a time: file navigation, completion, language servers, git, debugging. Each step shows the few lines of config involved and explains what they do.
It is made for developers who are curious about Emacs or tired of paying yearly for an IDE, and who bounced off a big preconfigured setup because they could not tell what was happening. You finish with a small config you understand and can change.
Lessons run in the browser as a PWA, with a copyable snippet and a check that tells you if your Emacs now behaves as expected. Basic guides are free. Advanced language setups and template packs are paid.

- Why this name
- A buffer is where Emacs holds your text; a bare one is the starting point. The name says you begin empty and build up.
In the first version
Members say which features they would use. It tells PWAS what people want; it changes no score.
One capability per lesson
Each lesson adds a single feature, such as completion or git, and nothing else, so you always know which line caused which behavior.

Explain-every-line snippets
Config snippets come with plain notes on each line: what it does, what it replaces and how to undo it.
No member yet
Setup check
Paste a short test into Emacs and paste the output back. Bare Buffer tells you whether the step worked and what to look at if not.
No member yet
Language tracks
Guided paths for common languages that take you from a bare buffer to completion, jump to definition, refactor and debug.

What it could be worthEstimate

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 can publish their annotated init file as a public page with the lessons it came from. Other Emacs users who read it see Bare Buffer's name and can open the same lessons.
- Do they become customers?
- Readers of a shared config are the same kind of people who would learn Emacs, so some may sign up. Test whether shared pages convert to free signups and then to paid.
- First customers
- Working developers on JetBrains IDEs, using Python or Go, who want to try Emacs and have a few hours a week to learn it.
- Where to reach them
- Hacker News: Share the free first lessons in a Show HN post and answer questions about Emacs setup there.
- Emacs communities: Post free lessons in Emacs forums and subreddits and ask for feedback on the lesson order.
- First milestone
- Ten paying subscribers from free lesson readers within two months, with at least a third finishing five lessons.

RisksAI inference
- CommercialEmacs users often prefer free docs and community guides. Willingness to pay for structured lessons is unproven; the evidence is a single small public discussion.
- TechnicalPackages and Emacs versions change often, so lessons and snippets can go stale and need ongoing maintenance.
- CommercialFree Emacs documentation and distributions already exist, so the paid tier must show clear value beyond them.
- TechnicalSetup checks rely on users pasting output by hand, which may feel clumsy and cannot detect every setup problem.
