## What is Whaile?

Whaile — yes, like the whale. It swallows files whole: the multi-gigabyte text and log files that crash TextEdit and choke VS Code open in about a second, the ones you'd normally only dare to touch from the terminal.

Built native for Mac and iPad, Whaile memory-maps the file instead of loading it into RAM, so an 8 GB log opens instantly and scrolls without a single dropped frame. No spinner. No "file too large." No waiting.

WHY WHAILE
• Open huge files fast — 1 GB, 8 GB, or bigger, ready in seconds
• Smooth, native scrolling with zero lag, even at the end of a billion-line file
• Search the whole file in seconds, not minutes
• Jump straight to any line number, instantly
• Tiny memory footprint — the system pages data in and out, your RAM stays free
• Fully sandboxed and offline — your files never leave your device

BUILT FOR
• SREs and platform engineers triaging giant nginx, syslog and crash logs
• Data engineers spot-checking 2 GB JSONL, NDJSON and CSV dumps before the real pipeline
• Anyone handed a log or export far too big for a normal editor

LET YOUR AI READ THE FILE
Whaile works with a free, open-source companion MCP server, so AI assistants like Claude can search and read your huge files directly — without blowing past the context window. Point your agent at a 10 GB incident log and ask it what went wrong, instead of scrolling by hand.

FAST BECAUSE OF HOW IT'S BUILT
• Memory-mapped file access — no full load, no copy
• Sparse line index built in the background for instant jump-to-line
• Byte-level search tuned for files that don't fit in memory

Whaile is a read-only viewer, on purpose: it's the fastest way to open, read, and search a file that's simply too big for everything else.
