Grammar check: local desktop install guide
A local grammar check that runs on hardware you control keeps drafts, squiggles, and suggestion cards on your desk instead of another browser writing tab. Lexicon does that work as an MIT desktop app: take the current Lexicon_*_x64-setup.exe from GitHub Releases on Windows (or the matching macOS dmg / Linux deb), open the editor, then proofread without creating an account.
- Proofread locally without a writing-cloud account
- Windows, macOS, and Linux builds under MIT
- Installer links point at GitHub Releases only
By Proof Quill editorial team Current release, published August 8, 2026
Install Lexicon 0.10.3
Windows
Paste into Explorer (double-click the downloaded setup):
Lexicon_*_x64-setup.exe Package: GitHub Releases Lexicon_*_x64-setup.exe on the current release tag (no winget package found for AashishH15/Lexicon on this review date). Prefer the plain x64 setup; arm64 and x86 setups are optional alts on the same tag..
Other Windows commands
Lexicon_*_x64-setup.exe Or download the file directly from the official GitHub release:
Download Windows x64 setup (.exe)Also on this release: Windows arm64 setup (.exe), Windows x86 setup (.exe)
Windows 10 or later, 64-bit preferred. Prefer Lexicon_*_x64-setup.exe from the current release tag on AashishH15/Lexicon; use arm64 or x86 setups when that matches your PC. Builds are not Authenticode-signed, so SmartScreen may prompt More info → Run anyway.
macOS
Paste into Finder (open the downloaded .dmg):
Lexicon_*_aarch64.dmg Package: GitHub Releases Lexicon_*_aarch64.dmg or Lexicon_*_x64.dmg on the same tag. No Homebrew cask for this Lexicon writing app was found on this review date (homebrew lexicon and lexicon-dj are unrelated)..
Other macOS commands
Lexicon_*_x64.dmg Or download the file directly from the official GitHub release:
Download macOS Apple silicon installer (.dmg)Also on this release: macOS Intel installer (.dmg)
macOS with a matching dmg from the current Lexicon release tag. Open Lexicon_*_aarch64.dmg on Apple silicon or Lexicon_*_x64.dmg on Intel. Builds are unsigned/pre-release; Gatekeeper may need Control-click → Open or Privacy & Security → Open Anyway.
Linux
Paste into your terminal:
sudo dpkg -i Lexicon_*_amd64.deb Package: GitHub Releases Lexicon_*_amd64.deb on the same tag. No snap or Flatpak package was verified for this guide on this review date..
Other Linux commands
Or download the file directly from the official GitHub release:
Download Linux amd64 package (.deb)A 64-bit Debian/Ubuntu-family desktop. Prefer Lexicon_*_amd64.deb from GitHub Releases. An AppImage is mentioned upstream for some tags but was not attached to the v0.10.3 assets verified for this guide.
Every file comes from AashishH15/Lexicon v0.10.3 on GitHub, the project's own release, unmodified.
People searching for grammar check usually want software they can install and trust, not another advertising page that wraps a cloud seat. Keep this grammar check install on GitHub Releases for AashishH15/Lexicon when you want a named Lexicon_*_x64-setup.exe, prove one local proofread, then tune optional models only after that path works.
Here grammar check means software that opens a desktop editor, runs local proofreading with inline suggestions, and keeps the binary on a machine you own. Lexicon is the MIT product this guide maps. Source and downloads live on AashishH15/Lexicon. The release door is GitHub Releases. Safe download path: download-safe path. Repo layout: GitHub overview. Which file: releases.
What a grammar check job needs
A grammar check job on a personal PC needs software that can catch grammar and spelling issues, show suggestion cards you understand, and leave browser extensions for people who want cloud sync instead. You choose a local client, keep sources on Releases, and avoid surprise toolbars mid-setup. A desktop grammar check client for offline proofreading reduces logins that only work while a vendor tab stays up.
Lexicon keeps that work on your machine. You download once, run the setup, open a draft, and leave the review panel ready. The everyday grammar check win is fewer half-finished “best grammar check download” pages than chasing a new website for every session.
MIT builds
The project licence on GitHub reports MIT for source. Free open-source downloads cover Lexicon_*_x64-setup.exe on the current release tag, with matching macOS dmg and Linux deb assets. Safety notes: is it safe.
GitHub Releases door
Windows Lexicon_*_x64-setup.exe ships on the current tag beside arm64/x86 setups, macOS dmg files, and Lexicon_*_amd64.deb. Prefer the x64 setup for this Windows-primary path.
Offline first
The product proofreads on your desk after the first fetch. Browser grammar tabs stay optional later, not a required grammar check signup before the first run.
- Prefer GitHub Releases over adware “grammar check download” portals.
- Prefer the named Windows x64 setup; no winget id was found here.
- Run the setup, then prove one local proofread with a short draft.
- Document the update door after the first successful pass.
Why this desktop path
Local grammar check work fails when the installer comes from a renamed mirror and the download folder never gets written down. Lexicon from Releases keeps filenames stable enough to put on a ticket: Lexicon_*_x64-setup.exe on Windows, Lexicon_*_aarch64.dmg or Lexicon_*_x64.dmg on macOS, and Lexicon_*_amd64.deb on Linux. Browser grammar tools exist, yet this guide prefers the current release tag as the honest grammar check door for desks.
Browser extension seats still win when you want suggestions inside Gmail or Docs. Online portals still win for a thirty-second paste. Choose this grammar check path when you want an MIT desktop grammar check window that can proofread offline without a commercial writing account.
No winget package id and no Homebrew cask for this Lexicon writing app were found on this review date. Prefer Lexicon_*_x64-setup.exe from GitHub Releases rather than inventing a package manager door for this grammar check client.
Install by operating system
Match the Install panel above. Prefer Lexicon_*_x64-setup.exe on 64-bit Windows, the matching macOS dmg for your chip, and Lexicon_*_amd64.deb on Debian or Ubuntu family desktops. Soft parks stay parked for winget and brew because those ids were not found.
| OS | Primary door | Notes |
|---|---|---|
| Windows | Lexicon_*_x64-setup.exe | No winget id found; Releases setup only; SmartScreen may prompt |
| macOS | Lexicon_*_aarch64.dmg or Lexicon_*_x64.dmg | No brew cask for this app; Gatekeeper may block unsigned builds |
| Linux | sudo dpkg -i Lexicon_*_amd64.deb | Deb on reviewed tag; no AppImage on v0.10.3 |
Longer OS paths: Windows, macOS, Linux. Machine chooser: for this computer. File map: releases.
Eight steps to first proofread
- Open GitHub Releases for AashishH15/Lexicon Open the official current release tag and confirm you see Lexicon_*_x64-setup.exe for this Windows path, not a renamed mirror setup from a review portal.
- Download Lexicon_*_x64-setup.exe Prefer Lexicon_*_x64-setup.exe for a normal 64-bit Windows grammar check install. No winget package id was found on this review date, so keep the Releases setup as the Windows door. Arm64 and x86 setups sit on the same tag when your PC needs them.
- Run the setup once Double-click the downloaded setup so the installer can place Lexicon. SmartScreen may show Windows protected your PC on unsigned builds; choose More info, then Run anyway after you confirm the GitHub Releases URL.
- Confirm Lexicon opens Launch Lexicon from the Start menu so the grammar check editor window appears before you paste a draft.
- Paste or open a short draft Open a short sample paragraph in the editor so you have real text ready for one local grammar check pass.
- Run proofread once Use the local proofreading tools so squiggles and suggestion cards appear. The LanguageTool engine ships with the app and does not require the optional AI model download.
- Keep one update door Return to the same GitHub Releases Lexicon_*_x64-setup.exe name for the next bump, or use Check for updates in Settings. Skip adware grammar check portals that only rank for writing searches.
- Optional local AI model later After one proofread works, choose Light or Standard model download only if you want rewrite and tone tools. Soft parks stay parked for winget and brew.
First hour checklist: installed. First-run habits: first run.
First hour after install
Success is a grammar check window that accepts a short draft on a machine you control, not three download folders full of renamed setups. Launch Lexicon, prove one short proofread, then confirm one suggestion card before you trust a long manuscript pass.
SmartScreen and Gatekeeper prompts are common on first launch of unsigned indie builds. Prefer the Releases URL you typed yourself. Safety overview: is it safe. Model notes: local models.
How to choose a grammar check client
A careful grammar check buyer asks where drafts live, whether source is public, which platforms the window supports, and whether the download door is a named GitHub asset. Browser grammar tools answer with tabs and seats. Desktop clients answer with files and offline proofreading.
Pick a local desktop grammar check client when you want Lexicon on disk and proofread without a subscription. Pick a browser extension when install rights are missing. The criteria stay the same even if you later compare cloud writing seats for the same habit.
- Can you install from a filename you can write on a ticket?
- Does the licence let you read the client source?
- Can you proofread offline after the first download?
- Do drafts stay under your control on that desk?
Lexicon compared with other grammar check options
The table below is a desk grammar check comparison, not a ranking of writing portals. Online pages win at instant browser paste. This desktop grammar check client wins at a local MIT setup with public source for a desk grammar check path.
| Product | Price | Open source | Offline | Signup required | Verdict |
|---|---|---|---|---|---|
| Lexicon | Free (MIT) | Yes | Yes | No | Local desktop grammar check this guide maps |
| Browser grammar extensions | Free + seats | Usually no | Often needs network | Often yes for full features | Fast tab, weak install story |
| Web grammar check paste boxes | Free + ads | No | Needs network | Account optional | One-off queries, not a setup.exe door |
| Suite comment tools in Docs | With Office/Docs | No | Local files partial | Account often | Best when the draft already lives in the suite |
| Project homepage demo | Free | Same project | Browser | No | Quick try; not the Windows setup path |
Browser extension seats still win when you want suggestions inside mail. Suite tools still win for shared Docs comments. Lexicon is the install path when you want MIT builds, exact Releases names, and a desk grammar check that does not start with a signup. Longer comparison: vs browser grammar tools.
Free client vs paid seats
Lexicon itself is free under MIT. GitHub Releases assets named above have no paywall for the client. You may still see ads beside online grammar paste boxes if you keep those as a fallback.
Store platforms and adware portals sell extras and show ads. Those purchases do not replace a local grammar check Lexicon window, and this guide does not sell those seats. If you already have a browser habit, keep it until a local proofread sticks.
Mistakes that undo a grammar check install
Running a renamed portal setup instead of Lexicon_*_x64-setup.exe from Releases. Skipping SmartScreen confirmation of the GitHub URL. Expecting a winget or brew id that was not found. Mixing random setup.exe files without notes. Assuming an AppImage exists on every tag when v0.10.3 only shipped the deb for Linux.
- Take Lexicon_*_x64-setup.exe from GitHub Releases, not a renamed portal.
- Prove one local grammar check pass before chasing more tools.
- Write the update door on the machine ticket.
- Keep browser grammar tools as a fallback, not as the installer.
- Do not invent a winget or brew id that was not found.
Fix each mistake the same way: one honest door, one proven proofread, one documented path. Switch habits: switch from browser tools.

Repeatable desk habits
Write the grammar check update door on the machine ticket beside the OS version. Lexicon_*_x64-setup.exe, Lexicon_*_aarch64.dmg, and Lexicon_*_amd64.deb are different doors. Mixing them without notes creates duplicate folders and confused uninstalls after a reimage.
Family PCs, club laptops, and lab images all benefit from the same boring rhythm: one installer door, one folder, one documented proofread habit. That is how a local grammar check client stays boring for everyday desks in a good way.
Everyday limits
The grammar check client does not replace a shared Docs comment thread for team review. It does not make a bad draft into a good one by itself. It does not remove the need to trust the setup you downloaded. Offline use still needs network for the first grammar check fetch and for optional model downloads.
Settings that matter early
Choosing a grammar check language, keeping a personal dictionary for words that should not be flagged, and bookmarking Releases matter more than decorative chrome. Prove a local grammar check pass before you chase rewrite tones. Models guide: local models.
After the first proofread
Only after one grammar check proofread works should you explore optional AI tones or export to PDF. Keep Releases bookmarked. Prefer the tag that still ships your Windows setup. Update guide: update uninstall.
Keeping the job name clear
Here grammar check means a local client you install and operate. A review portal that only ranks for the head term is still the wrong binary. Prefer Lexicon_*_x64-setup.exe, then prove one proofread before you batch other downloads.
When someone pastes a random “best download” link into chat, ask for the GitHub Releases URL instead. The install path on this guide always returns to AashishH15/Lexicon for this grammar check.
Remember the job name: grammar check here means a local MIT client plus a setup you control. A download-portal mirror that only ranks for the head term is still the wrong binary. Prefer the named Releases assets, then prove one proofread before you add alternate doors.
Browser seats still win when you only need a thirty-second paste. Browser-only boards still win when install rights are missing. Choose Lexicon when you want MIT builds, exact Releases names, and a desk path that does not start with a signup.
Proof Quill publishes the install guide. Upstream Lexicon remains at AashishH15/Lexicon under MIT. When Releases change which OS assets appear, re-check the live list before you image a lab for this grammar check.
Lab and travel notes
Travel laptops benefit from a single documented installer door written beside the Start menu shortcut for Lexicon. Lab images drift when someone installs a second mirror during a blocked SmartScreen prompt. Prefer returning to the same Releases URL instead of inventing a new download mid-flight for a proofread session.
Club machines should receive the grammar check setup on hardware they control, plus a shared note for the update door. Shared desks should keep browser grammar tools available as a fallback until the local habit sticks for the whole room.
Classroom images should pin the exact setup filename beside the OS version. After every reimage, prove one short local proofread before you call the machine ready. That habit catches vanished shortcuts and adware installers that reappear from old bookmark exports.
Users who already live in browser grammar tools can keep that path. Treat the Windows setup as the windowed path for teammates who need a named Releases asset. The two can share habits when the room documents which path is official for demos of this grammar check.
Frequently asked questions
How do I install grammar check on Windows?
Download Lexicon_*_x64-setup.exe from the current release on AashishH15/Lexicon, run the setup, then open Lexicon from the Start menu. No winget package id was found on this review date, so keep the Releases setup as the Windows install door. Guide: install on Windows. Keep one door so the next bump stays honest.
Where should I download grammar check software?
Prefer GitHub Releases for AashishH15/Lexicon when you need Lexicon_*_x64-setup.exe for Windows, a matching macOS dmg, or Lexicon_*_amd64.deb on Linux. Skip download-portal wrappers that rename the setup for a search ranking. Details: download safe. Keep downloads on the project release list so the asset matches the tag you expect.
Is this grammar check free?
Lexicon is free under the MIT licence. GitHub Releases assets named above have no paywall for the desktop client. Optional local AI models download from Hugging Face when you choose them. This guide does not sell store seats, and ads on browser grammar tabs stay separate from that MIT licence for a local install.
Can I switch into this grammar check from browser grammar tools?
Yes. Install the Windows setup (or macOS dmg / Linux deb), prove one local proofread, then keep a browser grammar tab as a fallback if you still want extension suggestions. Guide: switch from browser tools. Comparison context: vs browser grammar tools. Browser drafts do not import automatically into the desktop window.
Does desktop grammar check work offline?
After the first download, Lexicon can proofread offline with the local engine already on disk. You still need network for the first fetch from GitHub Releases and for an optional model download. Offline habits: first run and first hour. A desk install does not require a writing-cloud account for this grammar check path.
