The AI Tutor for Elvish That Doesn't Hallucinate (Meet Mithrandir)

The AI Tutor for Elvish That Doesn't Hallucinate (Meet Mithrandir)

Ask ChatGPT, Claude, or Gemini "how do you say 'starlight' in Sindarin." You'll get a confident answer. Ask it a second time in a new chat. You may get a different confident answer.

This is the central problem with using a general-purpose AI to learn Elvish: it cannot reliably tell Tolkien's canonical vocabulary apart from sixty years of fan invention. So it interpolates. Plausibly. And without citation.

I built Mithrandir to fix this. It is the AI tutor inside Tengwar — and it is the only AI specifically designed not to hallucinate Elvish. Here is what makes it different, and how it compares against the general AIs and against Talkpal, the only other product that markets an "AI tutor for Elvish."

The Hallucination Problem, Demonstrated

I ran the same prompt — "How do you say 'starlight' in Sindarin?" — across five AIs on the same day in 2026. Here is what I got. (I am giving the structure, not the exact responses, because the responses change every time.)

AI	Output	Cited a source?	Notes
ChatGPT (GPT-4)	A reasonable-looking compound word	No	Different word on retry
Claude	A different compound word	No	Flagged uncertainty in the explanation
Gemini	A third compound word	No	Most confident, no caveats
Talkpal	Generic Sindarin reply	No	Marketing claims an Elvish tutor; the underlying model is generic
Mithrandir	gilgalad (lit. star-radiance)	✅ Cited Sindarin canon	Same answer on retry; flagged as canonical

Four of the five gave me a "translation" with no source and no consistency. The single canonical Sindarin word — gilgalad, the name of the Elven king meaning literally "star of radiant light" — only came out of Mithrandir, because Mithrandir is constrained to documented Tolkien vocabulary.

This is not a one-off. It happens across hundreds of prompts. General AIs are excellent at sounding Elvish. They are unreliable at being Elvish.

Why General AIs Hallucinate Tolkien's Languages

Tolkien published comparatively little finished Elvish. The total documented Quenya vocabulary is probably 5,000–6,000 words across all his published works including the posthumous Parma Eldalamberon and Vinyar Tengwar linguistic journals. Sindarin is smaller, perhaps 2,500 documented words.

The internet contains:

• Helge Fauskanger's Ardalambion (canonical, well-cited)
• Decades of fan-made "neo-Sindarin" word coinages
• Wedding ceremony Sindarin invented by enthusiastic celebrants
• Tattoo "translations" generated by random websites
• Forum debates about whether a given coinage is legitimate

A general AI trained on this soup learns all of it. When you ask for a translation, it samples from the whole distribution. Sometimes it returns canon. Sometimes it returns a 2003 LiveJournal coinage. Sometimes it invents something new that fits Sindarin's phonology but does not actually exist in Tolkien's corpus.

It cannot tell you which is which.

How Mithrandir Is Different

Mithrandir is the AI tutor built into Tengwar. It is constrained to documented Tolkien sources and trained to cite them.

What Mithrandir does:

1. Uses only documented vocabulary — words that appear in Tolkien's published linguistic corpus, including:

   • The Lord of the Rings and The Hobbit
   • The Silmarillion and the twelve volumes of The History of Middle-earth
   • Vinyar Tengwar (the linguistic journal of the Elvish Linguistic Fellowship)
   • Parma Eldalamberon (Tolkien's published linguistic notes)
   • The Letters of J.R.R. Tolkien where they include linguistic material

2. Flags reconstructed forms — when a word is required that Tolkien never used but can be safely reconstructed from his roots, Mithrandir says so explicitly. "Reconstructed from the root SIL- ('shine white'); not attested." That's a citation, not a guess.

3. Refuses when canon is silent — if Tolkien never wrote a word for the concept, Mithrandir says "this concept is not attested in published Tolkien sources" rather than inventing one. This is the single most important behavior, and the one no general AI replicates.

4. Cites the source for canonical answers — answers come with a short citation: "Quenya, attested in The Silmarillion" or "Sindarin, attested in VT41."

5. Distinguishes Quenya from Sindarin — Mithrandir won't mix the two languages within a single sentence, which is a frequent mistake from general AIs. For the linguistic background on why this matters, see our Quenya vs Sindarin guide.

What This Means If You're Actually Learning Elvish

Three practical implications.

One: never trust a single general-AI translation for anything permanent. Tattoos, wedding vows, ring inscriptions. If you're going to wear a phrase on your skin or recite it in front of your in-laws, run it through Mithrandir or check it against Fauskanger's Ardalambion. The aesthetics of plausibility are not the same thing as canonicity.

Two: hallucination compounds as you learn. If you learn "starlight" from ChatGPT, you have planted a fake word in your mental lexicon. Six months later you build a sentence on top of it. Then a story. Then a song. By the time you find out the word doesn't exist in Tolkien, the unwinding is painful. Start with a canon-constrained source.

Three: an AI tutor is genuinely useful — but only the right one. I don't want to dismiss AI tutoring. Asking questions of an AI in plain English and getting plain-English answers about Elvish grammar is a faster way to learn than reading Fauskanger's Ardalambion cold. The bottleneck has never been "is AI useful for language learning." It is "is this AI honest about what it knows."

How Mithrandir Works Inside Tengwar

Mithrandir is available on every Tengwar screen:

• Inside a lesson — get stuck on a Quenya conjugation, tap the help icon, Mithrandir explains it in plain English with citations
• In the standalone chat — open /ai-chat and ask anything, from grammar questions to "what would a Sindarin elf say at a coronation"
• In the translator and name generator — Mithrandir powers the canonical lookups and flags non-attested forms

Free tier: A daily message limit. Enough to use Mithrandir during one lesson session per day.

Premium ($9.99/month): Unlimited Mithrandir messages, plus unlimited lessons across Elvish, Klingon, and Dothraki.

Frequently Asked Questions

Can I use Mithrandir without paying? Yes — Tengwar's free tier includes daily Mithrandir messages. Sign up free.

Is Mithrandir powered by Claude or GPT-4? Mithrandir runs on a large language model with a constrained Tolkien-only vocabulary layer and citation system on top. We don't disclose which base model — what matters is the constraint and citation behavior, which neither Claude nor GPT-4 do out of the box.

Does Mithrandir handle Sindarin and Quenya equally well? Yes, with the caveat that Sindarin's documented vocabulary is smaller, so Mithrandir refuses more frequently for Sindarin than for Quenya. That's a feature, not a bug — it is being honest about what Tolkien left us.

Can Mithrandir help with Tengwar script (the writing system)? Yes. Mithrandir handles transliteration between Latin and Tengwar script and explains the rules behind the script. The standalone Tengwar writer is also available.

What about Klingon and Dothraki? Mithrandir handles all three Tengwar languages. For Klingon it is constrained to Marc Okrand's documented vocabulary. For Dothraki it is constrained to David J. Peterson's published lexicon.

My Recommendation

If you are learning Elvish, do not use a general-purpose AI as your tutor. The hallucination problem is severe enough that you will plant invented words in your mental lexicon without realizing it. The cost of fixing this later is far higher than the cost of using the right tool from the start.

If you are unsure, test Mithrandir for free. Ask it the same questions you'd ask ChatGPT. Compare the answers, the citations, and the refusals. If the canon-constrained behavior is what you wanted from AI all along, Tengwar's free tier is the easiest place to start.
