Analysis

An editorial look at what each product does well and who it suits.

ShellNewHandler
CovaSyn

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 CovaSyn.

How would you describe the primary audience of your product?

CovaSyn's answer:

Lab heads, quality control, analytical development and CMC teams in contract laboratories, CDMOs and specialty chemical companies, mainly in Germany, Austria and Switzerland.

What makes your product unique?

CovaSyn's answer:

CovaSyn brings checked chemistry into the AI assistant your lab already uses. General-purpose assistants often guess on spectra, stability or impurities. CovaSyn works the question through with tested methods and returns the source with every answer, so your experts can check it. Measured on MolecularIQ (Klambauer Lab, JKU Linz): AI alone 14 to 41 percent correct, with CovaSyn 76 to 92 percent.

Why should a person choose your product over its competitors?

CovaSyn's answer:

Your team keeps working where it already works: no new interface, no data migration. Every answer comes with its source, so it can be checked before it goes into a report or a batch decision. Your data stays in the EU on servers in Nuremberg, Germany, with no training on customer data. If your IT rules out external hosting, CovaSyn runs on your own infrastructure behind your firewall.

What's the story behind your product?

CovaSyn's answer:

CovaSyn GmbH was founded in Leipzig, Germany, by Dr. Oliver Kraft. The starting point: general AI assistants give confident answers on spectra, stability and impurities that often do not hold up in the lab. CovaSyn closes that gap. Your team keeps its assistant, and the chemistry behind each answer is checked.

  • 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
