As answered by people managing Obsidian and AppErgo.
AppErgo's answer:
AppErgo brings together more than 200 browser tools in one fast, lightweight and privacy-friendly toolbox. Every tool is 100% free, works without an account, runs directly in the browser, avoids intrusive advertising, and is fully responsive on both desktop and mobile.
AppErgo's answer:
AppErgo was created in France in 2026 as an independent project developed by a solo creator. Its name combines “App”, for applications and online tools, with “Ergo”, reflecting a focus on ergonomics, simplicity and ease of use. The project started with a small collection of practical tools and gradually grew into a toolbox of more than 200 tools covering text, codes and puzzles, dates, audio, games and everyday tasks.
AppErgo's answer:
AppErgo is primarily built with static HTML, CSS and vanilla JavaScript. Its pages are generated through a custom administration system based on PHP and MySQL, while the public tools rely on standard browser technologies such as SVG, Canvas and the Web Audio API. All processing takes place directly in the browser, without external APIs or remote processing services.
AppErgo's answer:
AppErgo is designed for students, teachers, developers, creators, office workers, puzzle enthusiasts and everyday users who need a practical online tool without creating an account or navigating a complicated service. Its wide range of tools supports both occasional tasks and regular use on desktop or mobile.
AppErgo's answer:
AppErgo is built for people who want to open a tool, complete a task and move on. It combines more than 200 fast, lightweight and responsive tools with clear interfaces and local browser processing. There is no signup, no intrusive advertising and no unnecessary upload of personal data. The tools are available directly on desktop and mobile, without installing anything.
AppErgo's answer:
AppErgo is primarily designed for individual users rather than named enterprise customers. Its audience includes students, teachers, developers, creators, puzzle enthusiasts and anyone looking for a quick browser-based tool.

The reasons live somewhere else: in practice notes in an Obsidian vault, one note per convention, with the repos it has held in. A note starts as an idea, moves to trialing, and only becomes enforced once I've applied it again in a few... - Source: dev.to / 3 days ago
