What is Plain Text Computing?

Plain text computing is the enduring practice of storing information as sequences of human-readable characters encoded in standard character sets (primarily UTF-8), completely free of proprietary binary packaging or application-specific container formats.

In The Pragmatic Programmer (1999), Andrew Hunt and David Thomas articulated the timeless maxim: “Keep Knowledge in Plain Text.” They argued that proprietary binary formats inevitably become obsolete when software vendors pivot, go bankrupt, or change file versions. Plain text, by contrast, is universal, future-proof, and fundamentally democratizing.

The architectural advantages of plain text

Choosing plain text over database-backed note apps provides significant operational advantages:

1. Immortality and future-proofing

A plain text file written in 1976 on a Unix terminal using ASCII can be opened without modification on an Apple Silicon Mac today. No word processor or database engine can match this fifty-year backward and forward compatibility.

2. Universal interoperability

Plain text files integrate with the entire computing ecosystem:

• Version control systems like Git can diff and track line-by-line changes.
• Terminal utilities like grep, ripgrep, sed, and awk can search and transform millions of words in milliseconds.
• Command-line automation scripts, backup tools like rsync, and Spotlight desktop search index plain text natively.

3. Complete transparency

There are no hidden database flags, deleted record remnants, or telemetry trackers buried inside a .md file. What you inspect in a text editor is the exact ground truth of your file.

## Decisions
1. Transition all meeting records to local Markdown vaults.
2. Deprecate cloud transcription bots in favor of on-device Whisper.

Plain text in Oyma

Oyma is built on the conviction that notes should never be trapped inside SQLite databases, Electron IndexedDB caches, or remote MongoDB clusters.

Every note you create or edit in Oyma:

• Exists as a standard .md file in a folder you choose on macOS.
• Uses standard CommonMark and GFM syntax for tables, task lists, and headers.
• Employs bidirectional [[WikiLinks]] and YAML frontmatter fully compatible with Obsidian, Logseq, and Bear.
• Can be inspected, edited, or backed up by any other Mac utility at any time.

With Oyma, you get the fluid visual experience of a modern native Mac application without sacrificing the permanence and purity of plain text.
