The essentials, done right

A place for the text that is happening right now.

Write without ceremony

Tabs at the top, a genuinely open writing area and fast keyboard commands. Open text, CSV, Markdown, code and unknown text extensions.

Nothing disappears

Drafts return after you close the app. Every note keeps up to 40 recent versions, while closed tabs remain searchable for 30 days.

Compare side by side

Open a full-screen Diff and review changes between files or between versions of the same note.

Built by developers, for developers

Rastro is made by developers for classic programming workflows and AI-assisted development, often called vibe coding.

</>AI-ASSISTEDOpenAI Codex

OpenAI Codex supported research, prototyping, implementation and testing. Product direction and final decisions remain human.

SHAPED BY REAL WORK

Rastro gets better with the people who use it.

Less is more. We want to keep Rastro simple—but anything can improve when it solves a real everyday need. Send a short note about what breaks your flow or would make your work lighter. From time to time, we review the suggestions and choose what fits without losing the simplicity.
