AudioPen
AudioPen turns rambling voice notes into clean, polished text in a style and language you choose, with control over rewrite depth and length, apps on every device, and a keyboard and hot key that drop finished writing into any app.
- Solves the blank-page problem by turning talk into an editable draft
- Genuine control over edit depth, length and style
- Keeps your ideas and voice rather than generating new text
- Works everywhere you write, across every device
- Not a live dictation tool for typing into every app
- Not a meeting transcriber with speaker labels
- Requires sending voice recordings to a cloud service
Buildin.ai
Buildin is an all-in-one AI workspace for docs, mind maps and databases, with lossless Notion import, AI throughout, cross-platform sync, an open API and MCP, and a distinctive built-in paid-subscription feature so you can monetise your content directly.
- Workspace plus built-in content monetisation
- Lossless Notion import lowers switching cost
- AI woven through docs and databases
- Extensible via open API and MCP
- Challenger against a deeply entrenched incumbent
- Main draw (monetisation) is irrelevant if you won't sell
