Why we built a Markdown viewer instead of another editor

Every AI coding session ends the same way: with a document. A spec the agent wrote before touching code. A migration plan. A skills file explaining how it should behave next time. These documents are the actual work product of AI-assisted development — and almost nobody has a good place to read them.

The scrollback problem

Ask yourself where you read your agent's last plan. If you're like most developers we talk to, the answer is one of: a terminal buffer you have to scroll carefully because it's mixed with build output, a chat window where the doc is sandwiched between your own prompts, or — if you're organized — a `.md` file opened in an editor designed for writing, not reading.

All three share the same flaw: they treat the document as incidental. But it isn't incidental. The spec is the feature. The plan is the review surface. When your agent gets a requirement wrong, the cheapest place to catch it is while reading the plan — before any code exists.

Reading is not a degraded form of editing. In an agent-driven workflow, it's the highest-leverage activity there is.

What editors get wrong for this job

We're not here to knock editors — PrettyMD's founders use them daily. But look at the reading experience they offer:

Each of these made sense when documents were things humans wrote occasionally. None make sense when agents generate documents continuously and the human's job is to review them fast.

The reader-first alternative

PrettyMD started from a different question: not "how should people write Markdown?" but "how should people read Markdown that machines wrote?" Three answers fell out of that:

Folder-first, rendered. Point it at a project folder and every Markdown file is there, rendered beautifully — Mermaid diagrams, tables, code — in tabs, with search across the whole set. Reading five related docs feels like reading one continuous thing.

Change tracking. The app remembers when you last read each file and highlights what's new. A revised 400-line plan costs you 40 lines of attention, not twenty minutes.

The comment loop. This is the big one. Highlight any line and leave a comment. Compatible agents can read the sidecar comment, reply there, and update the Markdown while PrettyMD stays a read-only review surface. Review happens inside the document, where the context already lives.

Deliberately not an editor

People ask why PrettyMD doesn't just add editing. Because the moment it does, it becomes a worse version of tools that already exist. The value is the focus: a tool whose only job is making agent output readable, diffable, and commentable. Write in your editor. Read in PrettyMD. The workflow splits cleanly along exactly the line where existing tools stop caring.

If that's the loop you're in — agents producing documents, you producing judgment — give the seven-day trial a spin. And if you want the long-form comparisons first: we've written honest breakdowns against Typora and Obsidian.
