## TESIGN TAKE

It spends its effort on opening fast and not freezing rather than on features — a difference you feel immediately if you read logs for a living.

## WHY IT MATTERS

Past a few hundred megabytes, most editors stall on open. miu maps the file instead of loading it whole, so a large file opens straight away, and being written directly against C++ and Win32 keeps it light.

## BUILD FROM THIS

- Text and colour emoji are rendered with DirectWrite. It has regular-expression search and replace with case and whole-word options, multiple cursors, rectangular selection, unlimited undo, a dark mode and F1 help, and uses Google’s compact_enc_det to detect encodings. Built binaries are on GitHub Releases.

## WHO IT'S FOR

- People who open big logs and data files often, and Windows users after a lighter Notepad.

## START IN 5 MINUTES

```
# Download the binary from GitHub Releases and run it — there is no install step.
```

## CAVEATS

- The documentation is Japanese-first. It is built primarily for Windows (the repository also lists macOS and iOS targets), and building it yourself means preparing the encoding-detection library first.

## How to read this

- This file was produced by the same build, from the same data, as the tesign.com item page. The text is editorial; the numbers are stored observations.
- null in the JSON means not observed — never zero. The Markdown writes [unconfirmed] for it.
- Star total = the value last checked on GitHub (stars_checked_at) + increases observed via GH Archive since. The 24h · 7d · 30d gains are GH Archive hourly events summed to the reference time (as_of). No score of ours.
- A summary, not legal advice.
