Show score rationale

The keyword 'Altcode Cheat Sheet' suggests people are looking for a reference, but not necessarily a paid tool. The HN mention could indicate a tech-savvy audience that values efficiency but may be averse to paying for something free alternatives exist.

Fill the critical gaps (max 2)

“I don’t know” is fine — we give how to get evidence; we never invent interviews or payments.

Q: Do users actually search for alt codes in a way that a tool can make faster than their current method?

If the current workaround (e.g., Google search) is already quick, the tool's value is marginal.

How to get evidence: Run a simple survey or interview with 5–10 people who use alt codes weekly. Ask them to describe their current process and time spent. Also, test a landing page

Q: What is the willingness to pay for a convenience layer on top of free alt code lists?

The product is a utility; users may expect it to be free. Without a clear paid feature, revenue is impossible.

How to get evidence: Include a pricing section on the landing page with two options (free with ads, or $2 one-time for no ads + extra features). Measure which option gets more click

04 Business breakdown

Who needs this

Windows users who frequently type special characters (e.g., ©, ®, é, ñ) – including writers, translators, data entry professionals, and forum moderators.

Job to be done

Quickly find the Alt code for a special character and insert it into a document without breaking flow or opening a separate app.

Why they might pay

If the tool saves time and reduces friction (no need to memorize or search), users may pay for convenience, especially if they use it multiple times a day.

Alternatives

Windows Character Map, online cheat sheets (e.g., alt-codes.net), Google search, or memorizing common codes.

Differentiation wedge

A single-page searchable web app that works offline and lets you copy the character with one click. No install, no ads (for paid version).

OPC scope

MVP: a single-page web app with a search box, a table of alt codes, and a copy-to-clipboard button. No accounts, no database; all data in a static JSON file.

Open questions

  • How often do power users need alt codes?
  • Would a browser extension be more useful than a web app?
  • What is the acceptable price point?
  • Is there a mobile use case (e.g., on a tablet)?

05 Search & acquisition

Primary channel:

SEO (long-tail keywords), Reddit (r/Windows, r/typing, r/techsupport), Hacker News (if relevant), and YouTube tutorials on typing special characters.

Click a keyword to copy. Tags: AI candidate / queried / thin sample.

Talking points

  • Stop memorizing Alt codes – search and copy in one click.
  • Free tool that saves you 2 minutes every time you need a special character.
  • Works offline, no install, no ads (paid version).

Minimum experiment 06 Minimum validation experiment

One falsifiable step before you continue or stop.

Valid signal = real task completion, reuse, or pay intent — with observe + continue/stop.

Create a simple landing page with a search box that, when typed, shows a few example alt codes (e.g., ©, ™, é). Include a 'Get the full tool' button and a waitlist sign-up form.

Observe

Number of sign-ups, time spent on page, and whether visitors type characters into the search box.

Continue

At least 20 sign-ups in one week, or 100 unique visitors with 10+ searches per visitor.

Stop

Fewer than 5 sign-ups and no repeat visits; also if people comment that the free alternatives are 'good enough'.

Share the landing page on Reddit (r/Windows, r/typing) and a relevant HN thread (if any) with a question: 'Would you use this?'

Observe

Number of upvotes, comments, and any direct expressions of interest or willingness to pay.

Continue

Positive feedback and at least 10 people say they'd use it or ask to be notified.

Stop

Mixed or negative feedback, especially if users point out existing free tools that are 'just as good'.

How should I read the score?

Current OPC feasibility score is 3/100. It is an AI-assisted executability check, not a market guarantee. Low scores mean “prove demand first,” not “never build.”

None

Model hypothesis

  • Writers, translators, and data-entry workers may need alt codes frequently and might find a searchable tool more efficient than a static cheat sheet.
  • People who use special characters occasionally may not pay, but heavy users (e.g., transcriptionists) might.
  • The HN mention could indicate a tech-savvy audience that expects free tools, so monetization must be subtle.

Known facts

  • Alt codes are a Windows feature that allows typing special characters using the Alt key plus a numeric keypad code.
  • Windows has a built-in Character Map utility.
  • There are many free online alt code lists and cheat sheets.

Unverified assumptions

  • There is a segment of users who need alt codes frequently and find current methods slow.
  • A searchable, copy-paste tool would be faster than a static list.
  • Users might pay a small one-time fee for convenience.

AI inference: The keyword 'Altcode Cheat Sheet' suggests people are looking for a reference, but not necessarily a paid tool. The HN mention could indicate a tech-savvy audience that values efficiency but may be averse to paying for something free alternatives exist.
