## Overall context

Improve clarity and keyboard accessibility in the project settings.

Priority for agent: High

Make Save changes the primary action. Align the buttons with the fields and increase the button contrast.

Your screenshot. Your context. Ready to paste.

Give the picture a point.

A screenshot shows the symptom.
Your agent still needs the context.

A raw screenshot leaves the important parts implicit. What is wrong? What should change? Which part matters? Imnota helps you make it explicit, right in your local workflow.

Just the screenshot Where should I look?
Example project settings screen. The Save changes button has low contrast and the action row is misaligned.
The screen is visible. The intention is missing.
With Imnota Here. This. Because.

More context inside it.

Annotations and context, side by side. Example project.
1

Make visual feedback precise

Point directly at the part of a screen that needs attention. Keep editable annotations separate from the original screenshot.

2

Keep project context together

Organize related screenshots into local collections. Add shared context, then archive and restore collections as the work changes.

3

Export a handoff your agent can read

Copy Markdown, image or both. Large collections split automatically into readable prompt bundles.

The receiving editor chooses which clipboard formats it accepts. Separate copy actions are always available.

Local-first, by design.

Your project stays a folder on your machine.

Plain files you can copy, back up and version-control. Keep your screenshots and context together, in a workspace you choose.

A few practical answers.

Does Imnota upload my screenshots?

No. Imnota’s core workflow uses local files and has no cloud sync or cloud storage dependency. You decide where to paste or share an exported bundle.

Do I need an AI account to use it?

No. Imnota has no account requirement and no built-in AI provider connection. It prepares context for the assistant or coding agent you already use.

Which operating systems are supported?

Imnota’s development and packaging targets are Windows, macOS and Linux. Check the latest release for available desktop downloads.

What does the export contain?

A fresh, timestamped Markdown and high-resolution PNG set for the current collection. The Markdown includes collection context, screenshot descriptions, agent priorities and text or callout notes. Large collections may split automatically. You can copy Markdown, image or both, depending on what your receiving editor accepts.

Can I build Imnota from source?

Yes. You need Node.js 20+, Corepack and a platform-supported Electron environment. Follow the manual build instructions or the development README.

Is Imnota Apple-notarised?

The current release is not Apple-notarised. The README explains how to open it through System Settings, Privacy & Security, Open Anyway. Read the macOS installation guidance. Do not disable Gatekeeper.
