Ritemark - 2026 Pricing, Features, Reviews & Alternatives

Ritemark is a free, MIT-licensed, open-source desktop markdown editor for macOS (Apple Silicon and Intel) and Windows that converts a local folder into a structured writing workspace. All files are stored as plain .md files on the user's device with no cloud account, sync service, or proprietary format required. The application combines a WYSIWYG markdown editor with real-time formatting preview, a file manager, a built-in VS Code terminal, and an AI sidebar in a single interface.

Ritemark supports four AI agents: a built-in Ritemark Agent for writing tasks, Claude Code (Anthropic), OpenAI Codex, and OpenCode, all operated through the user's own provider API keys to avoid vendor lock-in. Agents read, edit, and save files directly in the user's folder without copy-pasting between applications. A Plan mode displays agent intentions before any file changes are applied. Scheduled agents run on a configurable timer for recurring tasks such as daily briefings or weekly summaries. The visual Flows editor chains LLM, Image, and Claude Code nodes into repeatable, multi-step AI workflows. An Agent Library auto-discovers .claude/ agents, skills, and commands. The integrated Electron browser supports local HTML files, external URLs, and localhost dev servers, with consent-gated context sharing that lets agents read the active tab's URL, title, and page outline. AI browser control allows agents to navigate, click, fill forms, and scroll within the visible tab.

Beyond AI capabilities, Ritemark includes Mermaid diagram rendering with PNG export, an embedded draw.io diagram editor, spreadsheet support for CSV and .xlsx files with a formula bar and multi-sheet tabs, PDF and Word (.docx) document preview, and export to PDF and Word while preserving the markdown source. Audio transcription is available via on-device Whisper (no external data transmission) or ElevenLabs Scribe (cloud, with speaker separation), with AI-generated summaries, decisions, action items, and key quotes from transcripts. Local voice dictation is powered by whisper.cpp and supports 50-plus languages with no cloud calls. Additional features include parallel agent chat threads, a prompt queue of up to 10 follow-ups per chat, a VS Code extensions marketplace, YAML front-matter and document properties, find-in-document with live match highlighting, an inline Table of Contents, and dark mode. Ritemark requires no account or subscription and carries no paid tier.
