Show HN: Ghostwriter – Structured thinking tool for teams using mind maps and AI

https://app.gwriter.io/
11•mitch_said•8mo ago
Hi HN,

Longtime lurker, first time Show-er here.

We built Ghostwriter to solve a problem we kept hitting: turning inconsistent, fragmented thoughts into something structured and useful, whether that’s a presentation, a project plan, or a meeting agenda.

We’re 3 co-founders with backgrounds in consulting, engineering and design. Over the past two years, we’ve been working with clients: running workshops, giving status updates and solving complex problems together. Again and again, we wished for a tool that married collaborative thinking with smooth facilitation features and the ability to create polished outputs.

What Ghostwriter does:

- You can start from scratch or bring in content like notes, documents, presentations, transcripts, links

- It structures your inputs into a top-down, question-led mind map, with succinct answers supported by a clear rationale

- AI helps you generate, refine, and reorganize ideas, all while staying grounded in your inputs using RAG

- Export the result to PowerPoint, PDF, or keep working inside the tool

- Use it for team problem-solving, meeting facilitation, planning, or creating presentations

Ghostwriter has changed our own workflow: instead of collating multiple sources of info and ping-ponging deliverables back and forth with formatting and content changes, we now focus on pure thinking, collaborating in a shared space that maintains structure and clarity from initial ideation to final output.

We’re in open beta and would love your feedback on what’s working, what’s unclear, and what you’d want it to do better. Sign up free at https://gwriter.io.

Thanks!
