About

Koi Editor is a fast, minimal, scriptable code and text editor for macOS, designed around low typing latency, large-file performance, and local workflows. Koi provides multi-cursor editing, multiple synchronized views of the same document, project-wide search, file and buffer navigation, syntax highlighting, code completion, configurable themes and keybindings, and extensive text-editing commands. The editor is designed to remain responsive with large source files, logs, and structured text, and has been tested with files containing tens of millions of lines while retaining syntax highlighting and core editing functionality. Optional AI features support local models through Ollama for code completion and inline assistance. Koi can operate entirely offline, requires no account, and includes no telemetry. Koi is built specifically for Apple Silicon Macs and combines a custom editing engine with native macOS integration.

About

MangoWriter is a secure text editor for Windows designed to run completely offline with no cloud, AI, network connections, or telemetry, offering a familiar, simple editing experience while keeping content private by default. It uses state-of-the-art AES-256-GCM encryption with strong key derivation (Argon2id) and optional keyfile two-factor support, ensuring no plaintext is ever written to disk and eliminating caches or temp files. MangoWriter protects your work with a secure clipboard that binds copied content to the current session, an instant lock screen to mask content when stepping away, and one-click bulk redaction tools to permanently black out selected text across documents. Sensitive buffers are zeroed after use and your password never gets stored on disk, with key material kept only in secure memory while a document is unlocked. It is delivered as clean, code-signed builds available as an MSI installer or portable ZIP and includes secure export options.
