Built Supanote for devs who share more than plain text

I share code, logs, and markdown all day — bug reports, runbooks, API payloads, stack traces, internal docs.

Most tools treat everything like a flat text file: wrong preview, weak formatting, dead-end links with no way to follow up.

So I built Supanote.

Core flow is simple: paste → clean link → proper preview

But I wanted it to feel like a real dev tool, not a generic note app:

Rich markdown primitives — beyond basic headings and code blocks:

• :::note / :::warning / :::tip callouts

• :::tabs for multi-section docs

• :::terminal, :::request, :::file blocks

• :::checklist, :::progress, :::stat for runbooks & status updates

Paste a technical doc and it renders like one.

Threaded replies — follow-up on a shared snippet? Reply with a linked note. Full thread view, reply policies (open link / signed-in only / disabled). Lightweight discussion around shared content, not a one-way dump.

Also: auto format detection (JSON, logs, code, HTML…), optional encryption, burn-after-read, REST API + MCP for AI workflows.

Still early, but I use it daily.
