Grammar, rewrites, OCR & web tools powered entirely by your own local LLM (Ollama, LM Studio, llama.cpp). No cloud, no telemetry. LocalQuill — AI Writing Assistant · Runs on Your Computer Grammar, rewriting, translation and OCR — powered by the model on your machine. Not our servers. Not anyone's cloud. The one you installed.
🔒 Real Privacy. Not Privacy Theatre. No telemetry. No analytics. No tracking. No sign-in required. Your text travels only to the address you type in Settings — and nowhere else. Uninstalling removes everything, completely.
✨ Hold Alt — The Interface Appears When You Want It Nothing pops up on its own. Toolbars appear while you hold Alt and vanish the moment you let go, so you can read an article or drag through a paragraph without anything chasing your cursor. Alt + point at a picture → Extract text, Explain image, Save image Alt + select text → Fix, Rewrite, Translate, Shorten, Humanise, and more Alt was chosen deliberately — it scrolls nothing, types nothing, and leaves Ctrl and Shift free for the browser and the page. While you are typing it does nothing at all. A small reminder appears the first few times, then retires itself for good. Prefer the old always-on behaviour? One toggle in Settings.
✍️ Writing Tools Live grammar and spelling correction in any text field on any site. Rewrite, shorten, expand, change tone, humanise, simplify, or explain any selection. Summarise a paragraph or an entire page. Translate to and from Hindi, Spanish, French, German, Chinese, Arabic, Japanese, and English. Right-click any selection for the same actions. Custom dictionary for words you never want flagged.
⚡ Instant Offline Checks 332 common misspellings and a set of fixed-idiom rules are caught by built-in rules — no model round-trip, no waiting. "For all intensive purposes", "could care less", "peaked my interest", "baited breath", "free reign", "deep seeded", advice vs advise, affect vs effect. British and American spellings both pass through untouched.
🖼️ Images, OCR & Accessibility Hold Alt and point at any image to extract its text, explain it, or save it. Drag a selection box over any part of your screen to pull text straight out of it. Ask questions about screenshots, charts, and photos. Explain image returns the same eight sections every time — summary, type, details, the text inside it, the colour palette with hex codes, what it means, and what it was unsure about. It also writes a ready-to-paste alt attribute, with a Copy Alt Text button. No "image of" prefix, because screen readers already announce that. Decorative images are told to use an empty alt rather than handed a fake description. Full-page capture with highlighter and freehand annotation tools — export as PNG or PDF.
📄 AI Docs A complete document editor with Word-style formatting and live grammar checking built in. Code mode includes a side-by-side preview and reusable snippets. Attach a screenshot and let the model build a layout to match it. Export to plain text, HTML, Markdown, or PDF.
✉️ Email Writer 465 templates across HR, Career, Corporate, Finance, Legal, and Sales. A Generate button appears directly inside Gmail and Outlook — no switching tabs, no copy-pasting. It signs off with your real name, not [Your Name].
🛠️ Page Tools A full suite of developer and SEO utilities built into every page: SEO meta tags, Open Graph, and schema inspection UTM builder, link checker, tracker and privacy audit Accessibility, contrast, page score, and Web Vitals checks Element inspector, colour, font, and image extraction Click heatmap, device preview, and live page editing Page diff, network report, ruler, and cache clearing
💬 QuillHelp A chat assistant that acts — not just describes. Press / for 47 built-in commands. Say "switch to Ollama", "use qwen2.5-coder", or "dark mode" and it happens immediately, no settings screen required. It knows how every feature works, opens any tool by name, and hands you the guide and privacy policy with no internet connection needed.
🚫 No-LLM Mode Turn AI off completely and every AI surface disappears — no underlines, no page scan, no toolbars, no image chip, and the AI entries leave the right-click menu too. Every offline page tool keeps working. For anyone who wants the developer toolkit without running a model at all.
⏰ Everything Else Reminders with desktop notifications AI memory — it learns your writing voice over time Mini clipboard manager for text and images 16 keyboard shortcuts, all unassigned by default so nothing clashes Custom dictionary Per-site disable Four themes, including a colourful Fruits mode Performance mode for older machines
