Analysis

ShellNewHandler
MarcoFly.app

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 ShellNewHandler and MarcoFly.app.

What makes your product unique?

MarcoFly.app's answer:

MarcoFLY is an epistemic control layer for generative AI. Instead of focusing only on generating answers, it helps users understand the status of each claim by distinguishing confidence, inference, uncertainty, and the need for verification.

It combines epistemic labels, configurable safeguards, multi-LLM workflows, web research, peer review, document attachments, transferable session context, and a BYOK architecture in one Progressive Web App.

MarcoFLY is model-agnostic: users can work with different AI providers while keeping control of their own provider accounts, API keys, and usage costs. It does not promise perfect answers or eliminate hallucinations; it makes uncertainty more visible and supports a more structured verification workflow.

Why should a person choose your product over its competitors?

MarcoFly.app's answer:

People should choose MarcoFLY when they want more than a conventional AI chat experience. It provides a structured way to inspect AI-generated information, identify uncertainty, compare responses from different models, and decide what requires further verification.

MarcoFLY is also flexible: users can connect their own AI provider keys through BYOK instead of being locked into a single model or provider. The platform is free to use and supports developers, researchers, professionals, and AI power users who value transparency, control, and responsible human-in-the-loop interaction.

It is not designed to replace general-purpose AI assistants, but to add an epistemic control and verification layer above them.

How would you describe the primary audience of your product?

MarcoFly.app's answer:

MarcoFLY is primarily designed for developers, AI engineers, researchers, analysts, professionals, founders, educators, and advanced AI users who rely on generative AI for research, coding, decision support, documentation, and complex problem-solving.

It is especially useful for people who work with multiple LLM providers and want a structured workflow for identifying uncertainty, comparing model responses, checking sources, and keeping the human user responsible for final verification.

What's the story behind your product?

MarcoFly.app's answer:

MarcoFLY began with a practical problem: generative AI can produce fluent and confident answers without clearly showing what is known, inferred, uncertain, or potentially incorrect.

As an independent full-stack developer and framework architect, I worked extensively with multiple AI models and saw that better prompts alone were not enough. I wanted to create a structured interaction method that would make uncertainty more visible and encourage active human verification.

This led to the MarcoFLY Framework and its multi-LLM Progressive Web App. The project continues to evolve as an independent, bootstrapped initiative focused on more transparent, controlled, and responsible human-AI interaction.

Which are the primary technologies used for building your product?

MarcoFly.app's answer:

MarcoFLY is built as a Progressive Web App using modern web technologies, including SvelteKit, TypeScript, JavaScript, HTML, and CSS.

The platform integrates multiple AI providers and routing services through API-based connections and a BYOK architecture. Its infrastructure and deployment use Cloudflare services, while the broader ecosystem includes web research, real-time streaming, peer review, structured session state, document processing, and knowledge-base/RAG-oriented workflows.

The exact provider and infrastructure configuration may evolve as the framework and application continue to develop.

Who are some of the biggest customers of your product?

MarcoFly.app's answer:

MarcoFLY currently does not have publicly disclosed enterprise customers. It is an independent, bootstrapped project in active development and validation.

The current audience includes individual developers, researchers, professionals, founders, educators, and AI power users who are testing the framework and providing feedback. Customer and user references will be added as formal partnerships or publicly shareable case studies become available.

  • 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
