Three steps to a richer scene.
Expand Story plugs directly into your editor. There’s nothing to copy, paste, or switch between — the AI reads your surrounding context and expands in place, matching your prose style and your world’s rules.
Select your passage
Highlight any text in your manuscript — one sentence, a paragraph, or a whole scene. The AI scales its expansion to match your selection.
Choose an expand mode
Pick Scene Depth, Sensory Detail, Inner Thought, Backstory, or World-Building. Each mode targets a different dimension of prose richness.
Review, accept, or iterate
Expanded text appears colour-coded in your editor. Accept all, accept by paragraph, or run another pass with a different mode or custom prompt.
Scene Depth
Adds narrative weight, atmosphere, and physical grounding to thin passages. The default expansion mode.
Most popularSensory Detail
Weaves in sight, sound, smell, touch, and taste to make scenes vivid and embodied.
Show don’t tellInner Thought
Adds interior monologue and emotional interiority in your POV character’s authentic voice.
Deep POVBackstory
Surfaces relevant character history and past events naturally within the current scene.
Character depthWorld-Building
Integrates setting, lore, and world rules — drawn from your Lore Book — into the prose organically.
Lore-connectedTurn a sketch into
a fully lived moment.
Thin passages often arrive that way intentionally — you’re moving through plot. Scene Depth expansion takes those scaffolding paragraphs and layers in narrative weight, atmospheric grounding, and physical presence without altering your story beats.
- Atmospheric setting details woven into action
- Pacing expanded without changing plot sequence
- Character physicality and presence added
- Word count target optionally specified
The fire was out. The room was cold. He sat in the dark and thought about what she had said.
After — Scene Depth
The last ember in the grate had given up an hour ago. The room had taken on the quality of a held breath — cold that presses rather than touches. He sat in the wingback with both hands around a glass of whisky that had long since gone to room temperature, turning it slowly. What she had said kept arriving in a different order each time, as if his mind were still looking for a version that made sense.
Make readers feel
what they read.
The most powerful writing puts the reader in the body of the character. Sensory Detail expansion identifies every beat in your selection and asks: what does this look like, sound like, smell like, feel like? Then it answers — in your voice.
- All five senses incorporated naturally
- Avoids purple prose — sensory detail stays purposeful
- Specific over generic — concrete nouns and verbs
- Mood and tone matched to existing scene energy
The bread was warm in her hands, yeasty and dense, its crust yielding with a sound like crumpled paper. Butter went on in a cold slab that softened fast, pooling into the crumb’s pores.
Deep POV that puts
readers inside the mind.
Interior monologue is what separates literary fiction from plot summaries. Inner Thought expansion adds your character’s unfiltered internal experience — doubt, desire, memory, contradiction — in a voice that’s unmistakably theirs.
- Character voice learned from surrounding chapters
- Emotional contradictions and subtext surfaced
- Free indirect discourse handled naturally
- Character arc and motivation kept consistent
He nodded. “Of course,” he said. She turned away.
After — Inner Thought
Of course. Two words. He had practiced something else entirely — something honest — and then opened his mouth and let the coward out instead.
◇ Marcus · Inner Monologue
He nodded. “Of course,” he said, and the words tasted like nothing. She turned away — and it struck him that she already knew.
Weave history in.
Never break the scene.
Backstory is most powerful when it arrives uninvited — triggered by a smell, a word, a gesture. Backstory expansion finds the natural hooks in your selection and surfaces relevant character history through memory, association, and reflex rather than exposition dumps.
- History surfaced through associative triggers
- Lore Book character histories consulted automatically
- Flashback transitions handled smoothly
- No continuity errors — cross-checked against your timeline
She recognized the street. It had been called something else when she was nine — she couldn’t retrieve the name, only the quality of the light on summer evenings, that particular amber that made the whole block look like a photograph of itself. The pharmacy on the corner had been a bakery then. She and her brother used to press their faces to the glass. She wasn’t sure when she’d last thought about him.
Your world, rendered
in every sentence.
Fantasy, sci-fi, and historical fiction demand that world-building is present everywhere — not just in dedicated exposition chapters. World-Building expansion draws directly from your Lore Book to seed lore, culture, and setting into ordinary scenes, naturally and without overexplaining.
- Lore Book entries used as expansion source
- World detail shown, not explained
- Cultures, customs, and geography woven in organically
- Zero invented lore — only what you’ve established

The Accord Markets
Weekly trade gathering, neutral ground. No weapons drawn within 40 paces of the gate.
Veth Incense
Burned at thresholds to ward river-spirits. Smells of pine resin and seawater.
The market was already loud when she arrived. Smoke from the veth-burners at the gate drifted low — that resinous smell, half pine, half salt — and she passed through it the way everyone did, one hand brushed across the gate post, an old habit she’d never bothered to discard.
See the difference
expansion makes.
Same story. Same author voice. Just richer, deeper, and more fully realised.
More than just a summarizer.
