A quiet companion, at every stageof writing.
From the first draft to the final revision. None of these features replace your writing — they help you see further.
In short: Frame is a local-first desktop app for novelists. Its AI co-writer suggests your next sentence in your own voice, its copy-editor flags setting contradictions and prose issues across chapters, and its Reader Lab lets 18 virtual readers react to your draft before you publish. Free to start; Standard is US$11.99/month. macOS and Windows.
Co-writer
An AI that knows your voice
The AI in Frame reads your entire manuscript — the voice of your previous chapters, how your characters speak, the tension of the current scene. The next sentence should read as if you wrote it.
- Context window— Full manuscript summary + last three chapters
- Ghost suggestion— Tab to accept, ignore to dismiss
- Conversational mode— Rewrite, variants, brainstorm
- Style profile— The AI learns from samples of your writing
Copy-editor
An editor who reads with you
Grammar and spelling are basics. Frame's linter looks for Show vs. Tell, repetition, point-of-view drift — the things a professional editor would see first.
- Show, Don't Tell— Emotion-as-description detection
- Repetition— Paragraph-level highlights
- POV drift— First/third-person consistency
- Rhythm— Sentence-length heatmap (coming soon)
She opened the door very happily. The room was truly beautiful. Yeon-hui was surprised very again.
Local-first & private
Your manuscript on your disk
Every manuscript is saved as a single local file on your disk. Delete your account, let the company disappear, lose your internet — your writing remains yours. When you use an AI feature, only the needed text is sent for processing, then deleted right after — never used to train AI models.
- One project, one local file
- Full offline functionality
- Not used for AI training— text deleted after processing
- Export— docx
Focus mode
A writing space without distraction
The UI disappears; only the current sentence remains. Choose typing sounds from mechanical keyboards to fountain pens. The dark mode is easy on the eyes in low light.
- Focus mode— Only the current sentence in full contrast
- Dark mode— An easy-on-the-eyes dark palette
- Typing sounds— Mechanical
- Writing stats— Daily goals, time, session length
Reader Lab
Virtual reader feedback before you publish
Before sending a manuscript into the world, persona-based virtual readers read it first. Emotional curves, engagement scores, and star ratings show where each scene lands.
- 18 reader personas— Literary fiction reader, YA reader, etc.
- Emotional curve— Per-scene tension visualized
- Overall rating— 5-point scale with reasoning
- Redesign suggestions— Highlights for improvement
The silence at the window creates tension — Yeon-hui's emotion could surface a little more.
