About

(Koi Editor is now Peeknext) Peeknext is a professional text and code editor for macOS, built around three principles: fast, local, and scriptable. Designed for low-latency editing and large-file performance, Peeknext includes multi-cursor editing, synchronized views, project-wide search, context-aware autocomplete, syntax highlighting for 30+ languages, code folding, file outlines, customizable themes and keybindings, and extensive editing commands. Peeknext requires no account, includes no telemetry, and works entirely offline. Configuration and keybindings use plain text files, while custom editor commands can be written in Python. Optional AI features connect to local models through Ollama for code completion and inline assistance. Built for Apple Silicon Macs, Peeknext combines a high-performance editing core with native macOS integration.

About

Notula is a free WYSIWYG Markdown editor for the docs as code already in your git repository. It opens the repo as a tree of documents and edits them with no syntax on screen - no hashes, no asterisks, no table pipes, not even on the line the cursor is on - then adds the review layer a code editor has no answer for: comment on a passage, reply, mention someone, suggest an edit, resolve. A mention arrives as a notification and waits in an inbox. Threads are committed beside the document as plain files. Nothing is written into the Markdown, and a one-word edit stays a one-word diff. Tables are edited as tables and Mermaid blocks are drawn as diagrams. It drives the git already on the machine, and never rewrites history, stages the whole worktree or switches a branch. Free, no account, no server. macOS and Windows, no Linux build yet. The source is closed and the builds are not code-signed yet, so the first launch takes one extra step.
