# Nicekit

Nicekit is a lookup and tool kit. It shows a visitor their public IP, a download speed test, origin, weather at that location, a best-guess VPN flag, and the DNS resolver the browser used.

It also ships file and web tools, all listed on the home page:

- Browser-only file utilities (merge/split/rotate PDF, images to PDF, MP4 to MP3) — files never leave the machine. The four PDF tools share a tab at /tools/pdf.
- Web fetchers: a Loom video/transcript downloader, a *.vercel.app subdomain availability checker, and one AI chat exporter at /tools/chat-export that reads public share links from Claude, ChatGPT, DeepSeek, Qwen and Grok (Markdown, TXT, DOCX, PDF).

IPs, fingerprints, and lookup results are not stored.

## Human interface

Open / in a browser for the tool index and the who-am-I tile.

Open /whoami for the full diagnostic card: public IP, speed, origin, weather, VPN guess and browser.

For why the project exists and what tech it exercises, see /about.

## Machine interfaces

curl, wget, and httpie against / receive the public IP as text/plain.

A request to / with Accept: application/json (and without preferring text/html) receives JSON with ip, origin, weather, and request. Speed, DNS, and VPN stay in the browser and are not in that JSON.
