Search interest 03 Search trend evidence
Is anyone searching? Relative interest — not monthly volume.
Trends 0–100 is relative interest, not monthly volume; 0 ≠ no demand.

04 Business breakdown
Who needs this
Academic writers, graduate students, journal editors, and copy editors who need to format titles according to a specific style guide.
Job to be done
When I have a title or sentence, I want to convert it to title case following the exact rules of AP, APA, Chicago, or MLA, so I don't have to manually correct small words.
Why they might pay
If the tool eliminates a repetitive, error-prone task and saves 5–10 minutes per document, a user might pay a small fee for convenience and accuracy, especially if they handle many manuscripts.
Alternatives
Generic case converters (e.g., titlecase.com, Convert Case), manual editing in Word/Google Docs, style guides themselves, and grammar tools like Grammarly (though they don't do style-specific title case well).
Differentiation wedge
Start with APA title case only, as it is common in academia. Provide a clean, fast, no-login tool. Add a waitlist for other styles.
OPC scope
Single-page web app with a text input, a button, and a rules engine for APA title case. No accounts, no storage, no backend beyond a static site with JavaScript. Use a well-tested library or implement rules manually.
Open questions
- How often do users need this? Daily, weekly, or only during paper submission?
- Which style is most requested? AP or APA?
- Do users prefer a web tool, a browser extension, or an API?
- Would a one-time payment be more acceptable than a subscription?
05 Search & acquisition

Content marketing with a free tool page; SEO for long-tail keywords; posting in academic subreddits and writing forums; Hacker News Show HN.

Talking points
- Accurate title casing for four major style guides in one tool
- No more manual fixing of 'the' and 'and'
- Built for editors and students, not just generic case conversion
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.
Build a single-page tool that converts a sentence to APA title case. Include a text area, a convert button, and a result area. Add a small note: 'AP, Chicago, MLA coming soon. Join the waitlist.'
Post the tool to a relevant community (e.g., a subreddit for academic writing or a Hacker News Show HN) and drive a small amount of traffic.
After one week, analyze the data and decide whether to build the other styles or pivot.

Current OPC feasibility score is 5/100. It is an AI-assisted executability check, not a market guarantee. Low scores mean “prove demand first,” not “never build.”
07 Evidence & boundaries
Demand evidence summary
No traceable external evidence. The hypothesis is that style-specific title casing is a recurring pain for a niche audience, but this is unverified.
External record
None
User-stated
None
Model hypothesis
- People who write academic papers or edit manuscripts often need to format titles in a specific style; they may currently copy-paste into a generic case converter and then manually fix small words.
- The presence of the keyword on Hacker News suggests some people think about this problem, but it does not confirm a large or paying audience.
Known facts
- Title case rules differ across AP, APA, Chicago, and MLA (e.g., capitalization of prepositions and conjunctions).
- Generic case converters exist and are often free.
- The keyword was mentioned on Hacker News, but no specific data is available.
Unverified assumptions
- There is a recurring need for style-specific title casing among a niche audience.
- Users are willing to switch from generic tools if accuracy is better.
- A one-person team can implement the rules accurately enough to be useful.
AI inference: The tool could be built client-side with JavaScript, using a rules engine based on style guides.,Potential future features include browser extensions, API access, or integration with citation managers.,Monetization could be a one-time fee or a low-cost subscription, but this is speculative.
