Show HN: BufferTab – minimal Markdown editor that lives in the browser's URL

Hi HN!

I just wanted to share this little website I built (mainly for myself).

It's a tiny markdown editor in your browser! The content gets persisted in the url of the page, which means you can easily share it with others or send it to your other devices.

As someone with many tabs open all the time, I find having such a scratchpad really valuable in my daily workflow.

Furthermore, it offers Speech-To-Text via OpenAI Whisper. Simply enter your OpenAI API key (it get's stored locally in the browser) and you can start talking!

This is great!

It would be even more useful if it had a pure playback mode, controlled by a simple query parameter. That way, we could create a document and send it to someone, and they would see just the view, no editing, no toolbar, full read-only. Then, if they would want to edit it, they could manually remove that query parameter (or press some key combination), and then it would unlock into fully editable mode (like it is right now).

you can toggle the edit mode to be just 'view' by pressing the edit button in the bottom right two times (alternative: cmd + e x2)

the edit mode gets persisted in the url as well!
