Context-Aware Inline Rewriting (Matches Your Doc)
A rewrite can be technically correct and still feel wrong — too formal for a casual thread, too generic to mention the project everyone in the doc already knows about, a tone that clashes with the sentence right before it. That happens when the tool rewrites your selection in isolation, with no idea what surrounds it. Context-aware rewriting fixes that by quietly reading the text around your selection so the edit fits where it’s going. This page explains how that works, why it matters, and how to tell whether a tool actually does it.
The problem with tunnel-vision rewrites
When an inline editor sends only your selected text to the AI, the model is guessing at everything it can’t see: the tone of the surrounding writing, the audience, the terminology, what came before and after. The result is a rewrite that’s fine on its own but doesn’t match its neighborhood. Common symptoms:
- Tone mismatch. You select one sentence in a relaxed Slack message; the rewrite comes back stiff and corporate because the AI had no signal that the rest of the message is casual.
- Lost terminology. The doc uses “the Atlas migration” throughout; the rewrite renames it “the data migration project” because it never saw the established term.
- Repetition or contradiction. The rewrite restates something the previous sentence already said, or subtly contradicts a point made earlier, because it couldn’t see the surrounding argument.
- Wrong register for the audience. A line in a legal clause gets rewritten with marketing flair; a line in a friendly email gets rewritten like a contract.
None of these are the model being “bad.” They’re the model being blind to context it was never given.
How context-aware rewriting works
A context-aware editor sends the AI more than just your selection. Alongside the text you highlighted, it includes a window of the surrounding text — typically some amount before and after your selection — and tells the model: rewrite this part, but make it fit this surrounding context.
With that window, the model can pick up:
- Tone and voice from the adjacent sentences, so the rewrite matches the register already established.
- Terminology and proper nouns used nearby, so it keeps the names and terms the document already uses.
- Flow — what the sentence needs to connect to before and after it, so the rewrite reads as part of the passage rather than a transplant.
The selection still defines what changes; the context defines how it should sound and what it should know. Only the selected text gets replaced — the surrounding text is read, not edited.
Context vs. a full style guide
Surrounding-context reading is about fitting the immediate document. It’s distinct from, and complementary to, a persistent style guide or persona memory, which carries your brand voice and rules across every document regardless of what’s around the selection. Context makes a rewrite fit this paragraph; a style guide makes every rewrite sound like you. The best results come from both together — see A living style guide for consistent AI rewrites.
The privacy consideration
Reading surrounding text means a bit more of your document is sent to the AI than just the selection. That’s a fair trade for quality, but it should be bounded and transparent: a sensible window of nearby text, not your entire document, and ideally something you can see or control. If a tool is vague about how much context it sends, that’s worth asking about — especially for sensitive work. (The broader question of what an inline editor transmits is its own topic; for sensitive contexts, a bring-your-own-key or local-model path keeps even the context on infrastructure you control.)
How to tell if a tool does it
You can test for context-awareness directly:
- Write a casual message, select one stiff sentence, and rewrite it. If the result matches the casual tone of the rest, the tool is reading context. If it comes back formal, it’s working in a vacuum.
- Use a doc with a distinctive project name and select a sentence that doesn’t contain it. A context-aware rewrite will tend to keep the established name; a blind one will generalize it away.
Context-aware rewriting in EditSnappy
EditSnappy quietly reads the text surrounding your selection so each rewrite matches the document it lives in — picking up the tone, terminology, and flow already on the page instead of editing in a vacuum. Only your selected text is replaced; the surrounding text is used as context, not changed. That context-fit runs through the same safe loop as every EditSnappy edit: it streams into place, shows as a diff before committing, preserves your formatting, and is undoable with one key. It works the same on Mac and Windows.
