What domain profiles do
Every domain of writing has its own grammar rules — or rather its own tolerance for what counts as an "error". Passive voice is bad in marketing copy and essential in academic writing. "Pursuant to" is not an error in a legal brief; it's deliberately precise language. "LVEF 45%" is not a typo; it's a standard clinical abbreviation.
Without domain profiles, a general grammar tool treats all of these as potential errors and may "fix" them into something that's actually wrong for the context. Pinogrammer's domain profiles solve this by loading a context-specific instruction set that overrides the general correction logic for known edge cases in that domain.
Each profile has two lists: what it corrects aggressively (genuine errors for that register) and what it protects (intentional patterns that should never be changed).
General profile
Corrects
- Subject-verb agreement errors
- Wrong tense usage
- Missing articles (a/an/the)
- Comma splices
- Dangling modifiers
- Spelling errors
Protects
- Common contractions (it's, don't)
- First-person register (I, we)
- Oxford comma variation
- Brand name capitalisation
Use General for emails, blog posts, social media, chat, and anything that doesn't require a specific specialist register.
Legal profile
Corrects
- Inconsistent defined-term usage
- Incorrect shall/will/may modal usage
- Ambiguous pronoun reference
- Inconsistent party name capitalisation
- Spelling and spacing in citations
Protects
- Latin terms (inter alia, prima facie)
- "hereinafter", "pursuant to", "notwithstanding"
- Passive constructions in obligations
- Boilerplate clause language
- Citation abbreviations (Id., Ibid., et al.)
The most important thing Legal profile does is not simplify. Without it, a general grammar corrector may replace "pursuant to Section 4(b)" with "under Section 4(b)" — technically English, but legally imprecise, and potentially meaningfully different in a signed agreement.
Academic profile
Corrects
- Informal register in formal sections
- Contractions in academic prose
- Vague quantifiers ("a lot of data")
- Incorrect citation punctuation
- Run-on sentences in abstracts
Protects
- Passive voice constructions
- Hedging language (may, might, appears)
- Discipline-specific jargon
- Third-person scholarly register
- Latin abbreviations (e.g., i.e., etc.)
Academic writing deliberately uses passive voice ("the samples were analysed…") to maintain objectivity and focus on the method rather than the researcher. A general grammar tool will flag every passive construction as "wordy" and suggest converting to active voice. Academic profile disables this.
Medical profile
Corrects
- Ambiguous pronoun reference in clinical notes
- Inconsistent date/time formatting
- Misspelled drug names (if clearly wrong)
- Incomplete sentences in referral letters
- Incorrect negation in diagnoses
Protects
- ICD-10 and ICD-11 codes
- Drug names and dosage abbreviations
- Clinical abbreviations (LVEF, RBC, BP, O2)
- Medical notation (q.d., b.i.d., p.r.n.)
- Procedure and diagnosis codes
Business profile
Corrects
- Excessive hedging in client communication
- Unnecessarily passive constructions
- Filler phrases ("as per my previous email…")
- Inconsistent number formatting
- Ambiguous action ownership ("it should be done")
Protects
- Business acronyms (ROI, EBITDA, KPI)
- Industry-standard terminology
- Numerical formatting (£1.2M, Q3 FY26)
- Action item phrasing in meeting notes
Creative profile
Corrects
- Actual spelling errors
- Broken syntax that reads as unintentional
- Inconsistent character name spelling
- Homophones (their/there/they're)
Protects
- Intentional sentence fragments
- Single-word paragraphs for effect
- Stylistic run-ons in stream-of-consciousness
- Unconventional capitalisation in dialogue
- Dialect and register variation in characters
Creative writing profiles are the hardest to get right because the line between "intentional style" and "error" is subjective. Pinogrammer uses confidence scoring: very low confidence corrections in Creative mode are suppressed. Only high-confidence genuine errors (homophones, missing words, broken sentences) surface as suggestions.
When and how to switch profiles
Profile switching takes about 2 seconds. Open the Pinogrammer toolbar popup and select the profile from the dropdown. Alternatively, click the profile chip in the suggestion card header to cycle through profiles. The active profile persists until you change it — it's not per-tab.
| If you're writing… | Use profile | Because… |
|---|---|---|
| A client proposal or board memo | Business | Direct and professional tone, protects industry terms |
| A research paper or dissertation | Academic | Passive voice preserved, citation format protected |
| A contract, NDA, or legal brief | Legal | Latin terms and formal register never simplified |
| A clinical note or referral letter | Medical | ICD codes, drug names, abbreviations all protected |
| A short story, script, or copy | Creative | Only genuine errors surfaced; style preserved |
| Email, Slack, social posts, everyday writing | General | Balanced corrections with no domain bias |
Pro: custom terminology glossary
PinoSuite Pro subscribers can add a custom glossary — a list of terms that should never be corrected, regardless of profile. This is useful for:
- Brand names with non-standard capitalisation (e.g., "iPhone", "eBay", "devOps")
- Internal company acronyms that standard models don't recognise
- Technical product names in specialist industries
- Proper nouns with unusual spelling
Glossary terms are stored locally in the extension and never sent to any server. They override all profile rules — if a term is in your glossary, it will never appear as an error suggestion.
