ShellNewHandler

WhittleOS is a decision OS for solo and indie founders. It answers the one question that saves you months: is a startup idea worth building, worth testing first, or worth dropping? Two ways in: - Check an idea you have — a Single Idea Check runs it through deal-breaker checks and a weighted...

    Build it / Test it first / Drop it — and it honestly returns nothing when a market is weak
  • Autonomous Discovery
    Sources real startup candidates from public sources and ranks them against your founder profile
  • Score computed in code
    A fixed weighted rubric sets the 0–100 total; the model rates each area but never sets the number
  • Linked evidence
    Every problem cited links to the page it was read on, or is labelled an estimate
  • No-call validation

Overall verdict

  • ShellNewHandler is a niche, lightweight utility hosted on SourceForge designed to give users more control over the Windows 'New' context menu (the ShellNew menu). It can be considered good for its specific narrow use case, but it is an older, minimally maintained tool that may not suit all users, especially those on modern Windows versions.

Why this product is good

  • Provides direct control over customizing the Windows right-click 'New' menu, allowing users to add or remove file type entries
  • Lightweight and free, without bundled bloatware typical of some other free utilities
  • Simple and focused in scope, making it easy to understand for its specific purpose
  • Open distribution via SourceForge allows transparency and no-cost access

Recommended for

  • Power users who want to declutter or customize the Windows New context menu
  • IT administrators managing standardized desktop environments across multiple machines
  • Users comfortable with older utility-style tools and Windows registry-related tweaks
  • Not recommended for casual users seeking modern, actively supported software with regular updates

Questions & Answers

As answered by people managing WhittleOS and ShellNewHandler.

What makes your product unique?

WhittleOS's answer

It's deliberately kill-biased and it shows its work. Instead of grading an idea you type in and flattering it, WhittleOS can source real candidates from public sources itself, checks that a documented problem sits behind each one, and computes the 0–100 score in code from a fixed weighted rubric — the model rates each area but never sets the total. When a market is genuinely weak it returns nothing, honestly, rather than a feel-good score. Every problem it cites links to the page it was read on.

Why should a person choose your product over its competitors?

WhittleOS's answer

Most idea validators grade an idea you bring and skew encouraging. WhittleOS does two things they don't: it sources the ideas itself across real markets, and it's built to find the reason an idea should die early. The verdict is bound to your founder profile — the same idea reads differently for a solo founder than a funded team — and it's auditable: you can see which check produced it. It won't claim accuracy no one can prove; it shows the evidence instead.

How would you describe the primary audience of your product?

WhittleOS's answer

Solo and indie founders — technical or not — who want a blunt, evidence-backed decision before spending months building. It assumes one person with limited time and budget, a no-call sales style, and a subscription-shaped product. Not for accelerators, agencies, or teams wanting a pitch-deck generator.

What's the story behind your product?

WhittleOS's answer

It started from a simple observation: most idea-validation tools are feel-good machines that tell founders what they want to hear, and a solo founder can lose months building on that. WhittleOS was built to be the opposite — a decision engine willing to say no, that sources its own evidence and computes the verdict in code so it can't talk itself into a pass.

Which are the primary technologies used for building your product?

WhittleOS's answer

Next.js and TypeScript on Vercel, with a Postgres database. The analysis runs on large language models (Claude and GPT) behind a fixed rubric and decision matrix — the models supply the ratings and evidence, but the weighting, scoring and gate are code.

  • I recently got libreoffice, but now the new option in right click looks like a mess. Can someone help me get rid of them please?
    Use Shell New Handler. Run the portable app and simply untick the items you don't want to appear in your new context menu. Source: about 4 years ago
  • This menu should be easy to add/remove programs to... Who is really creating Access Databases from this menu often enough to keep it here? (Not me!) Is there an easy way to edit this?
    I've always used ShellNewHandler for this. It's a really simple portable utility that allows you to remove most of the items from that menu. Tested it out on Windows 11 and it's still compatible. Source: over 5 years ago
