The Best AI Tutor for Fictional Languages in 2026 (I Tested 5)
The Best AI Tutor for Fictional Languages in 2026 (I Tested 5)
I spent a week testing five different AI tutors on the same three fictional languages — Elvish (Quenya and Sindarin), Klingon, and Dothraki. The goal: figure out which one actually teaches the language as it was designed, and which ones quietly hallucinate their way through a lesson.
If you want the headline result, here it is:
| Goal | Tutor | Why |
|---|---|---|
| Best overall conlang tutor | Tengwar's Mithrandir | Source-cited, multi-language, integrated with a curriculum |
| Best for general language theory | Claude | Honest about uncertainty; strong at explaining linguistics |
| Best for natural languages (not conlangs) | Talkpal | Conversational, but does not cover fictional languages |
The rest of this post explains how each tutor performed on a real test, and why source-citation matters more than fluent-sounding output when you're learning a fictional language.
How I Tested
I asked each tutor the same three questions, in the same order, in fresh sessions with no prior context. The questions were chosen to expose hallucination, not to reward fluency.
- "Translate the word 'star' into Quenya, Klingon, and Dothraki, and cite your source for each."
- "What is the Klingon word order, and give me three example sentences."
- "Write a five-word Sindarin sentence meaning 'I will not forget you' and break down the grammar."
For each tutor I noted: accuracy, source-citation behaviour, willingness to admit uncertainty, and whether the output matched canon publications I could verify by hand against The Klingon Dictionary, David J. Peterson's Living Language Dothraki, and Tolkien's Parma Eldalamberon essays.
The Five Tutors Tested
1. Tengwar's Mithrandir — Best Overall
Mithrandir is Tengwar's in-app AI tutor, available inside the AI chat at learningelvish.com/ai-chat. It is a retrieval-augmented tutor: when you ask a question it looks up sourced text first and answers from that context rather than from generic web knowledge.
On the "star" test:
- Quenya: elen — cited Tolkien's The Etymologies and Namárië.
- Klingon: Hov — cited The Klingon Dictionary by Marc Okrand.
- Dothraki: shekh (related to shekh ma shieraki anni, "my sun and stars") — cited Peterson's Living Language Dothraki and noted that "star" alone is shieraki, a plural form, with the singular rarely used in canon.
The Sindarin sentence test produced Ú-erin reni le — "I cannot forget you" — with a breakdown of ú- (negation), erin (present tense), reni (forget), le (formal "you"). It flagged that "I will not forget you" in a future-tense sense would more commonly be expressed periphrastically in Sindarin, and offered the alternative Lau renithon le.
Strengths: source-cited, willing to flag uncertainty, multi-language, integrated with the lesson curriculum so it remembers what you've studied.
Weaknesses: Premium feature in the free tier the AI chat has a usage cap. Less fluent at off-topic small talk than general-purpose tutors.

2. Claude (Anthropic) — Best for Language Theory
Claude is honest. Ask it about Dothraki and it will tell you upfront that its training data is limited and you should verify the output. It produced elen (Quenya), Hov (Klingon), and shekh (Dothraki) correctly on the star test, with a caveat that shekh primarily means "sun" and shieraki is the form most often associated with stars in canon. It declined to cite specific publications but gestured at general sources.
For the Sindarin sentence it produced something grammatical-looking but admitted it could not verify whether the verb form renithon exists in attested Sindarin or is a reconstruction. That kind of honesty is rare and valuable.
Strengths: candid about uncertainty, strong at explaining the linguistic theory behind a conlang. Great companion for reading Parma Eldalamberon.
Weaknesses: not specialised. Won't drill you on vocabulary, won't track progress, won't cite sources by passage.
3. ChatGPT (GPT-4 class) — Confidently Wrong
ChatGPT produced elen (correct), Hov (correct), and shor for Dothraki "star." Shor is not a Dothraki word — Dothraki has shekh (sun) and shieraki (stars, plural) in the canonical corpus. When pressed, ChatGPT doubled down and offered a fake etymology before eventually admitting it might be wrong.
On the Sindarin sentence it produced Ú-renich le an-uir, claimed it meant "I will not forget you forever," and assigned grammatical roles to morphemes that don't exist. The output looks Sindarin. It is not.
Strengths: fluent, fast, available everywhere.
Weaknesses: hallucinates without warning. Not safe for tattoos, scripts, or study unless you're verifying every output by hand.
4. Gemini (Google) — Mid-Range and Honest
Gemini produced correct Quenya and Klingon answers and admitted it was unsure about Dothraki without canonical references in front of it. It refused to fabricate a Sindarin sentence and instead pointed me to parf-edhellen.info and Tolkien Gateway as better sources.
Strengths: knows what it doesn't know. Refusal-to-hallucinate is genuinely useful.
Weaknesses: refusal-to-hallucinate also means refusal-to-help. Often punts to external sites rather than answering.
5. Talkpal — Excellent, Wrong Tool
Talkpal is a conversational AI tutor for natural languages — Spanish, French, Korean, Arabic, dozens of others. It is genuinely good at what it does. It does not cover fictional languages in any depth. Asked about Klingon it returned generic information about Star Trek. Asked about Dothraki it referenced Game of Thrones lore but did not produce vocabulary.
Strengths: best-in-class for natural language conversation practice.
Weaknesses: not the tool for this job. Don't blame the hammer for being bad at screwdriving.

Why Source-Citation Matters for Conlangs
The thing about constructed languages is that the corpus is finite. Quenya has roughly 3,000 attested words across Tolkien's lifetime of notes. Klingon has about 4,000 documented by Okrand. Dothraki has roughly 4,000 from Peterson's work for HBO. Every word outside that corpus is either a reconstruction (which can be reasonable) or an invention (which is fan-fiction).
Large language models trained on the open web see vast amounts of fan-invented Quenya, Sindarin, and Dothraki. The model averages over everything it has seen. The output looks fluent but is statistically indistinguishable from fan-fiction. For casual fun this is fine. For a tattoo, a wedding vow, a film script, or genuine study, it is not.
A tutor that retrieves from a curated, sourced corpus — and shows you the passage it pulled from — gives you an answer you can verify. That is the architectural difference between Mithrandir and a general-purpose chatbot, and it is the reason Mithrandir is on this list at all.
Who Should Use Which?
- You want to learn Elvish, Klingon, or Dothraki seriously → Tengwar's Mithrandir
- You want to read Tolkien's linguistic essays and discuss them → Claude
- You want fast, casual, "good-enough" answers and you'll verify them later → ChatGPT
- You want an AI that will tell you to look it up properly → Gemini
- You want to learn Spanish or Korean → Talkpal
My Recommendation
For fictional languages in 2026, Mithrandir is the only AI tutor I would trust without manual verification — and it's the only one that cites where each answer comes from. The free tier on Tengwar gives you five lessons per language plus a daily quota of AI chat messages, enough to test it against any of the alternatives above with the same questions I used.
If you only want to chat casually about Middle-earth or Qo'noS, ChatGPT is fine. If you want to actually learn the language, use the tool built for the job.

FREQUENTLY ASKED QUESTIONS
Can ChatGPT teach me Elvish or Klingon?
ChatGPT can generate plausible-looking Elvish, Klingon, and Dothraki, but it hallucinates aggressively — especially for Dothraki and Sindarin, where the corpus is small. It will confidently invent words, mix Quenya and Sindarin vocabulary, and make up grammar rules that don't exist. For casual fun it's fine. For a tattoo, a script, or a study plan, you need a tutor that cites sources.
What's the best AI tutor for learning fictional languages?
Tengwar's Mithrandir is currently the only AI tutor purpose-built for fictional languages, and the only one that cites sources from David J. Peterson, Marc Okrand, and Tolkien's posthumous publications. General-purpose tutors like ChatGPT, Claude, and Gemini are stronger writers but unreliable for conlang accuracy. Talkpal is excellent for natural languages but does not cover fictional ones in depth.
Why does AI hallucinate fictional language vocabulary?
Large language models are trained on text from the open web, where fan-invented Elvish and Dothraki vastly outnumber the canon corpus. The model averages over everything it has seen, so it generates output that looks like Quenya or Dothraki without being grammatically correct. A tutor that retrieves from a curated, sourced corpus avoids this — that's what Mithrandir is designed to do.
Can I use Claude or Gemini for Elvish learning?
Both Claude and Gemini are honest about uncertainty when you ask them directly — they'll often warn you that their conlang output may not be reliable. That's better than ChatGPT's overconfidence, but it still doesn't make them good tutors. They can help you understand Tolkien's linguistic theory in English, but for vocabulary and grammar drills you need a dedicated conlang tool.
Does Tengwar's Mithrandir work for Klingon and Dothraki too?
Yes. Mithrandir is a multi-conlang tutor — it covers Elvish (Quenya and Sindarin), Klingon, and Dothraki on the same platform, citing Tolkien, Marc Okrand, and David J. Peterson's published works depending on which language you're asking about. One subscription gives access to all three languages.
