Notestack turns any blog, newsletter, website or folder of markdown into a grounded research notebook, then into audio overviews, videos and launch kits, all traced back to the exact lines you actually wrote.

Who it is for

Writers who publish regularly and have an archive they are not getting full value from:

• Newsletter writers with hundreds of past issues and no easy way to find or reuse them.
• Bloggers who want old posts to keep working instead of sitting forgotten.
• Creators who need to turn writing into audio, video and social posts without starting from scratch each time.

What you get

• Your whole archive in one place. Connect a blog, newsletter or site once and new posts arrive on their own.
• Answers you can trust. Ask your archive anything and get replies that cite the exact lines behind them. If it is not in your writing, Notestack says so.
• Audio and video from your words. Two-host audio overviews, vertical shorts, explainers, audiograms and quote cards.
• Launch Kits. Hooks, threads, LinkedIn posts, Substack Notes, Bluesky posts, SEO packs and carousels, all editable.
• Scheduled posting. Plan a calendar and post to X, LinkedIn and Bluesky, with reminders and engagement tracking.
• Your voice, every time. Notestack learns how you write and uses that voice in every draft.
• See what you have written about. A topic map shows what you cover, what is rising and what has gone quiet.
• Old posts, new life. Resurfacing finds your evergreen pieces and suggests fresh angles to reshare them.

Why Notestack instead of NotebookLM

NotebookLM is a great general research notebook. Notestack is built for people who publish: it starts from your whole archive, stays in sync with it, cites the exact lines behind every answer, and turns what you wrote into things you can ship.
