ExpandNote vs Sill Notes

ExpandNote is an AI-powered note-taking app for capturing, organizing, and transforming your notes across devices. Write notes with markdown, add tags, dictate ideas with voice-to-text, and use AI Profiles to automatically process notes based on tags. Email-to-note lets you forward information into your notebook, while offline-first sync keeps your notes available when your connection is unreliable. Create, edit, search, favorite, archive, lock, and restore notes. Organize notes with tags and smart workflows. Use your own OpenAI, Anthropic, or OpenRouter API keys for AI-powered note workflows.

Sill is a small notepad for things you want to put down quickly and find again later. Notes are plain Markdown and stay plain. No smart quotes, no auto-capitalization, no hidden formatting: what you type is what is stored, and you can copy any note out as text at any time. Everything lives on your iPhone in a single local database. There is no account to create and no server in between, so Sill opens instantly and works the same with or without a network. If you also use the free Sill app for Mac, pair the two once by scanning a QR code. From then on they sync directly whenever they are near each other, over your local network or peer-to-peer Wi-Fi, with mutual TLS between the two devices. Nothing passes through the internet. The Mac app is optional: Sill on iPhone is a complete notepad on its own. A formatting bar above the keyboard adds headings, bold, italic, code, lists and checklists, all as plain Markdown. Return continues bullets, numbers and checkboxes. Copy as Markdown pastes as real lists and emphasis into Slack, Mail, Notes and Docs, and as the exact text everywhere else. Quiet: no analytics, no ads, no notifications, no third-party SDKs. Sill collects no data at all. Sill is free and open source under the MIT license.
