EmberWhere words come alive
Ember is the all-in-one writing studio with an AI assistant that enhances your craft, not replaces it. For Substack writers, authors, note-takers, and anyone who cares about their words.
Built for writers
Everything you need,
nothing you don't
Ember combines intelligent tools with a distraction-free canvas so you can focus on what matters — the writing.
Ignite AI
An assistant made for writers. Find sources, revise passages, rewrite sections — all without losing your voice.
Smart Proofreading
Powered by LanguageTool. Catch grammar issues, style inconsistencies, and typographical errors instantly.
Encrypted & Private
Your words are yours. End-to-end encrypted backup, and none of your text is ever used for AI training.
Native macOS Experience
Built with SwiftUI. Fast, beautiful, and feels right at home on your Mac. No Electron, no compromises.
Your co-pilot,
not your replacement
Ignite doesn't write for you, it thinks alongside you. Highlight a passage and ask for feedback. Need to find a source for an article? Ignite searches the web. Want a section tightened up? It suggests refinements while preserving your voice.
Polish every
last detail
Ember's dedicated proofreading tab, powered by LanguageTool, catches what your eyes miss. From capitalization errors to style repetitions, every issue is surfaced with clear explanations — and you can send any flagged item to Ignite for a deeper fix.
Your words stay yours
Every document is backed up with end-to-end encryption. Ember never uses your text to train AI models — period. Your creative work remains completely private and under your control.
End-to-end encrypted
Your documents are encrypted before they ever leave your Mac.
Secure cloud backup
Automatic, encrypted backups so you never lose a word.
No training on your data
Your text is never used to train any AI model. Full stop.
