Shakespeare Was Born in Warwickshire. So Was This AI Writing Engine.
Early Modern English is the language AI tools consistently get wrong. We built the only engine with a grammatically correct Shakespearean constraint system — from the county that gave the world its greatest writer.
William Shakespeare was baptised on 26 April 1564 in Stratford-upon-Avon, Warwickshire. He attended King's New School on Church Street, married Anne Hathaway two miles from town, and returned to Warwickshire to die in 1616. The world's greatest writer of English was a Midlander, through and through.
Ghostproof is UK-registered, British English by default, and built in the county that gave the world its most enduring voice. That is not a marketing claim. It is a fact of geography.
It is also, as it turns out, relevant.
The Problem With AI and Early Modern English
Every major AI writing tool handles contemporary prose reasonably well. None of them handle Elizabethan English correctly.
The failures are consistent and predictable. Ask any general-purpose AI to write in Shakespeare's style and it will produce something that sounds Shakespearean — heightened register, a sprinkling of thee and thou — while getting the grammar systematically wrong.
The most common errors:
Thee and thou confusion. Thou is subject. Thee is object. “Thou art brave” is correct. “I see thee” is correct. “Thee must go” is wrong. Every time. AI models treat them as interchangeable variants of you because they are statistically distributed that way in training data.
Verb conjugation drift. The correct second-person singular conjugations — dost, hath, wouldst, canst, art, wert — require different endings than modern English. “Thou do” is wrong. “Thou dost” is correct. AI models produce these correctly in isolation and incorrectly under pressure, defaulting to modern conjugations when the sentence gets complex.
Anachronism bleed. Contemporary vocabulary appears in early modern prose when the model runs out of period-appropriate alternatives. Characters “process” their grief. Relationships have “dynamics.” Someone is “basically” a villain. These words did not exist in Elizabethan English.
Contracted negatives. “Don't”, “can't”, “wouldn't” are modern contractions. Period-appropriate alternatives — “do not”, “cannot”, “would not” — feel stilted to a model trained on contemporary prose, so they drift.
The result is prose that reads like a Renaissance Faire impression: the costume is right, the grammar is wrong, and anyone who actually knows the period notices immediately.
What Ghostproof Built
We approached Shakespearean English as a constraint set, not a style. Style is subjective. Constraint is enforceable.
The Shakespearean / Early Modern English Voice DNA preset enforces:
- Correct pronoun usage: thou (subject), thee (object), thy/thine (possessive), ye/you (plural or formal). Applied grammatically, not statistically.
- Correct verb conjugations: dost, hath, wouldst, canst, art, wert — matched to their subjects and tenses.
- Period-appropriate contractions only: 'tis, ne'er, o'er, e'er, 'twas, 'twere — no modern contractions.
- Inverted syntax: “What manner of man art thou?” not “What kind of man are you?”
- Iambic-adjacent rhythm: sentences speakable aloud, as if written for a stage.
- Anachronism zero-tolerance: a dedicated ICK list removes modern idioms, psychological terminology, and contemporary vocabulary before they reach the page.
“What manner of man art thou, that dost stand thus at the threshold of mine patience? Speak plainly, for the hour grows late and I have little store of mercy left for those who waste it.”

The Chorus — A New Narrator Voice for RP
For Ghostproof RP, we built something different: The Bard's Eye.
Modelled on the choric figure from Shakespeare's history plays — most recognisably, the Chorus from Henry V — this narrator voice addresses the audience directly, making the impossible vivid through language alone. The prose enforces the same Early Modern English grammar as the Voice DNA preset: correct pronouns, correct conjugations, no anachronisms.
“O, for a muse of fire. The scene is set — a great hall, torchlit, wherein the players of this age do strut their hour. Thou art among them now. What part dost thou play? The court watches. The court always watches. And what the court sees, it remembers — longer than stone, longer than the names carved therein.”

Why This Matters for British Writers
Sudowrite launched in San Francisco in 2020. It does not have a Shakespearean mode. It does not enforce thee/thou/thine correctly. Its training data skews American English, its defaults produce American idioms, and its team has no particular reason to care about the specifics of Early Modern English grammar.
Ghostproof is UK-registered (Trademark UK00004364512), built on British English defaults, and — as of this week — the only AI writing engine with a grammatically correct Early Modern English constraint system.
Shakespeare was born 22 miles from Birmingham, in a half-timbered house on Henley Street, in a market town that still holds a festival in his honour every 23rd April. The language he wrote in is British heritage.
We think it deserves to be handled correctly.
