blas. Grammar Checker

blas. Grammar Checker catches writing issues while you type in ordinary browser text fields and most rich-text editors. Gmail compose boxes, Notion-style editors, comments, web forms, and the popup paste-to-check flow are the first-class targets. It checks English plus six Celtic languages. The Celtic language set is Irish, Welsh, Scottish Gaelic, Manx, Cornish, and Breton: - Irish - Welsh - Scottish Gaelic - Manx - Cornish - Breton Passive grammar checking is local and deterministic. The text you type into web pages is checked inside the extension, not uploaded to blas. or a third party merely because you type. Optional English cloud Deep Review is separate. **What it catches** English: - Common spelling mistakes and missing contraction apostrophes - Subject-verb agreement, pronoun case, articles, verb forms, and common preposition/collocation errors - Confusables such as its/it's, your/you're, their/there/they're, then/than, affect/effect, loose/lose, and other high-frequency pairs - Capitalisation, doubled words, spacing, and punctuation issues such as comma splices and missing commas after introductory transitions - Optional clarity/style hints when stricter review modes are enabled Irish and Welsh have the deepest Celtic rule coverage, including source-backed mutation, article, agreement, apostrophe, confusable, punctuation, and editor checks. Scottish Gaelic, Manx, Cornish, and Breton ship as conservative daily-writing assistants. They focus on source-backed spelling/orthography, mutation or article-trigger checks where implemented, punctuation, doubled words, capitalisation, and safe review prompts. Across all Celtic languages, suggestions are corrections or review prompts backed by rules, lexica, source corpora, or reviewer workflows. The extension does not generate Celtic-language rewrites. **How it works** - Underlines issues with a wavy red line in supported fields - Hover or click for a short explanation and a suggested fix - Accept, dismiss, ignore matching suggestions, or add spelling words to your local dictionary - Open the review panel for longer writing, category tabs, batch accept, undo, copy-fixed-text, and quick feedback - Use the popup paste checker when a page cannot safely support inline editing - Google Docs is fallback-only today: use the paste checker instead of inline Docs underlines - Optional account linking can sync ignores and saved words, save writing, and submit explicit reports to blas. - Optional push-to-talk dictation is available for Irish and Welsh after you enable microphone access in Settings - Linked Premium users can explicitly click English cloud Deep Review to send only the selected English text and context they choose; its setting is enabled by default, can be turned off in Settings, and rejects Celtic text **Privacy** - Passive grammar checking runs on-device - English cloud Deep Review makes no request before an explicit click. It sends only selected English text and context, and does not store raw review text or use it for training - No sign-in is required - Analytics is off by default and sends anonymous, de-identified usage data only after you opt in from Settings - Usage analytics never includes the text you type - False-positive reports preview the submitted fields before you send them - Accepted-correction practice scheduling is disabled in this release - When analytics is explicitly enabled, a de-identified sample of corrections you accept (the flagged word or phrase, accepted fix, rule id, and site domain, length-capped, never your full document) is sent to improve the models; turn analytics off to stop it - Dictation sends the recorded Irish/Welsh audio clip to blasapp.com for transcription only when you press the dictation shortcut **Boundaries** - This is a conservative writing assistant, not a replacement for human review - It does not claim to catch every grammar issue - It does not provide generated AI rewrites for Celtic languages - It does not translate text - It does not support inline Google Docs editing yet - English cloud Deep Review is a linked Premium feature, separate from passive checking. Its setting is enabled when no preference exists and respects an explicit off choice; cloud results also require an operator-deployed provider - Deep Review accepts English only and rejects Celtic text **Attribution** - Irish morphology uses forms from Bunachar Naisiunta Moirfeolaiochta (Foras na Gaeilge) under the Open Database Licence 1.0 - Welsh lexical data includes data extracted from English Wiktionary via Kaikki (CC0) - Other Celtic language data is bundled locally from the source-backed Blas data pipeline and release-asset gate - App code (C) blas. - all rights reserved
