An AI Latin tutor · in development
S·I·CLatinThus you learn Latin.
Read real Latin, word by word. A deterministic engine checks every claim the tutor makes about a form and its agreement before you see it, and every verdict names how much was checked. Where the teaching goes beyond what the engine can check, it says so.
Gallia est omnis dīvīsa in partēs trēs.
- form
- partēs
- lemma
- pars, partis f. — part, share
- readings
- nominative plural · vocative plural · accusative plural— all three are legal here. We show you the ambiguity rather than a guess.
Verified the form and the lemma, against the lexicon. Which reading this line needs is what you and the tutor work out — and that part is reasoning, not a verdict.
How it works
Latin is rule-dense. That is the point.
Most AI tutors are a chat window with a prompt. Sic Latin is built the other way round: a deterministic Latin engine does the checking, and the tutor does the teaching. Before an explanation reaches you, the engine has confirmed that every form in it is a real form and that every agreement it claims actually holds. What the engine cannot do is tell you the Latin means what you hoped — and drawing that line precisely, in public, is the whole design.
Read the real thing
Attested texts on a graded ladder, not invented sentences about farmers and sailors. Tap any word for its lemma and every reading the form legally has — where Latin is ambiguous, you see the ambiguity.
Grounded, not vibed
The tutor drafts; the engine gates. A claim about a form that the lexicon cannot support never reaches you — it goes back to be redrafted. Grammatical legality we can promise, at a named level of checking: forms, the agreement the tutor declares, and the relations the engine can require on its own — the bar we call L1. Ciceronian elegance we can only chase.
Nothing hides behind confidence
Every verdict names what it covered. When the tutor tells you why — that this ablative is means and not manner — that is reasoning, shown as reasoning, because no engine can check it. Most tools blur the two. We would rather you knew. The accuracy numbers we publish carry their method and their data version — reproducible by a skeptic, like everything else here.
Composition, when it is ready
Turning English into Latin is the exercise that makes grammar stick, and it needs a far stricter gate than reading does — verb and construction government, the level we call L2, because a sentence can be legal in every form and still wrong. That gate is not built yet. We would rather ship it late than mark your Latin wrong.
Meet your tutor
Latinatrix
She who Latinizes. Latinatrix is the voice inside Sic Latin: patient, exacting, a little dry. She will not tell you an answer you could have found; she will tell you what you already know that gets you there. Ask her in English, and she will keep the Latin in front of you.
Her vocabulary of praise is short. Get it right and she says the one word the app is named for.
Who it is for
Anyone who was told Latin is dead.
Homeschool and classical-school families who want a tutor that never loses patience at 9 p.m. and never invents a form to keep the conversation moving.
Students with a Wheelock or a Lingua Latina on the desk and a Caesar passage due Thursday.
Adults reading for pleasure — the Aeneid, the Vulgate, a medieval bestiary — who want a companion, not a curriculum.
Anyone in a choir who would like to know what they are singing.
Built with its readers
Authority lives in the citation, not the reviewer.
The engine only asserts what a deterministic rule can decide. Everything it cannot — is this paradigm cell real Latin or a dictionary artifact? does this verb really take that construction? — becomes a small, concrete question with a place for a source. Sic Latin is being built to put those questions in front of the people best equipped to answer them: its readers.
No credential gate
Teachers, students, philologists, the liturgically literate. An answer counts when it names a checkable source — a grammar section, an attested passage — and a citation is equally checkable no matter who attached it.
Agreement alone never wins
Answers are blind and independent, and consensus without a citation lands nothing: fluent, confident agreement is the failure mode this project was founded to distrust. Where the sources themselves disagree, the question is recorded as contested, with both sides cited — shown to you as honest ambiguity, not hidden behind a vote.
The work compounds, and is credited
A converged, cited answer becomes a permanent, versioned row in the engine's data — decided once, never re-litigated. Contributions are dedicated to the public domain, contributors are credited, and reliability is measured against known answers, never assumed from a title.
Waitlist
Be first through the door.
Sic Latin is in development. Leave an email and we will send exactly one message when it opens — and, if you like, an invitation to the early reading group, or to the first review queues if you would rather help decide the hard questions.
