ZenMark.dev — an AI-powered Markdown workspace for developers
Write specs, decisions, debug notes, snippets, and prompts. Keep your technical knowledge clean, searchable, and yours.
Markdown-first, no lock-in
Your notes are plain Markdown. Keep them local, version them, move them, export them.
BYOC via OpenRouter
You bring the key, you choose models, you control cost. No platform leash.
Calm UX for daily dev work
Fast, focused, and predictable. ZenMark is here to help you ship, not to entertain itself.
Core workflow
ZenMark is built around artefacts: things you actually reuse as a developer.
Create artefacts
Spec / ADR / Debug / README / Prompt. Use templates or start raw — Markdown stays the source of truth.
# Spec: feature-name

## Test plan
Organize
Folders, tags, and search. Find the one decision you made 3 months ago, before you re-do it badly.
Improve
AI Suggest: title/summary/tags (preview first). Plus selection actions: rewrite, expand, translate, explain.
{
"title": "Implement token refresh",
"summary": "Add refresh flow with retry + storage rules.",
"tags": ["auth", "frontend", "security"],
"notes": "Keep it explicit. No silent magic."
}
Export / Import
Markdown export. Optional frontmatter. Your knowledge stays portable.
BYOC & privacy
No server storage
Your data stays local. Keys stay local. ZenMark doesn’t run a backend that hoards your notes.
AI only when you click
No background calls. No surprise bills. If AI runs, it’s because you explicitly triggered an action.
Screenshots
Placeholders for now. Replace with real screenshots when ready.
FAQ
Is ZenMark a Notion clone?
No. ZenMark is a Markdown-first developer tool focused on artefacts (specs, ADRs, debug notes…). It avoids "workspace theater".
Does it store my notes on a server?
No. There is no forced backend storage. Your notes stay local unless you export or sync them yourself.
Which AI models are supported?
Whatever you select via OpenRouter. You bring the key, you choose the models.
Can I use it offline?
Yes — except AI actions, which obviously need network access to OpenRouter when you trigger them.
Is it free?
Yes.
How do I export?
Markdown. Optional frontmatter. No exotic formats required.
