Chess analysis, archive search and Instagram tools

Chess Coach imports your games from Chess.com or Lichess, or as pasted PGN, reviews them with Stockfish 18 running in your browser, explains the key moments in plain English, out loud if you like, and builds drills from your own mistakes. The engine runs on your device; the coach's narration and the hosted voice come from language and speech models through qpkit's server, or through a provider key you add.

1. Import games from Chess.com or Lichess, or paste a PGN.
2. Run the Stockfish review and inspect the key moments on the board.
3. Read or listen to the explanations and practice drills built from your mistakes.

Stockfish runs locally, while language-model narration and hosted voice use server or provider services. Check engine lines when an explanation seems uncertain.

Minerva Game Finder searches a catalog of 1,804,039 files across Minerva's 1,040 archive collections (No-Intro, Redump, TOSEC, MAME and more), collects the games you pick in a basket, and gives you one aria2 command that downloads only those files. A browser cannot join these torrent swarms, so the page hands over the torrent, the file numbers and a magnet link instead of the files.

1. Search the archive catalog and choose the collection or files you need.
2. Collect selected files in the basket and review the file numbers.
3. Use the generated aria2 command, torrent or magnet link with suitable software.

The page selects archive files; it does not download torrent content in the browser. Availability depends on the archive and swarm. Check rights for the files you access.

Instagram Follow Check reads the followers and following lists in your Instagram data export (the ZIP, its folder or the files inside) and lists who doesn't follow you back, who you don't follow back and your mutuals, with a CSV download. The comparison runs in your browser and the export never leaves your device.

1. Request an Instagram data export and download it to your device.
2. Open the ZIP, folder or follower and following files in Follow Check.
3. Review non-mutual follows and mutuals, then export CSV if needed.

The comparison reflects the downloaded export, not live Instagram data. You do not provide an Instagram password or automate follow and unfollow actions.
