🎯 The problem

A chatbot can explain how to rename 50 files, but it can't do it on your PC. An assistant that can touch files has two risks: it might break something, or it might say "done" when nothing happened. Link is built to avoid both.

⭐ What it does

Always close by: it drops down from the top of the screen on hover or a shortcut.

Plain words: I type or speak in Turkish or English and drag files onto it.

29 built-in tools: PDFs, Excel, files, images, text from images (OCR), conversions, reminders and more.

⚖️ Key decisions

Local first, AI second: in Automatic mode the built-in tools run first, without AI, and a model handles the rest. I can also switch to Local only or Gemini only.

Approval before action: before Link saves, moves, renames or deletes anything, it shows what will happen and waits for my OK.

Done means verified: a task only counts as done when Link has checked the result itself, for example the files on disk or the values in the Excel file.

🧪 How I check quality

Link has 1,262 automated tests. Also, 30 real Turkish and English tasks run against real test files. The first run, with no AI model at all, had 0 false completions (success reported without a real result), 0 damaged files and 0 crashes. 10 tasks were verified as done. The others stopped and said so, because plain sentences only reach those tools through a model.

The run also found a real bug: timer requests were wrongly refused. I fixed it and added a test for it.
