How it works
Elena al frente.
Arkia como medium.
ArkiaMate is infrastructure for digital memories of expert teachers. The pilot expert is Elena, an advanced English mentor. Arkia is the avatar shell that channels her — same form, one expert at a time.
How it works
Three steps. No fluff.
Designed for advanced students who want depth — not gamified streaks.
Calibrate (5 min)
A short adaptive assessment. Arkia identifies exactly where Elena’s method should pick up — no generic placement test.
Practice with Elena
Speak naturally. Elena’s voice and criterion respond in real time, channeled through Arkia. Corrections, examples, and follow-ups her way.
Grow on your map
Every session updates a personal mastery map. Friction surfaces. Wins compound. You always know what to practice next.
The technology
Six pillars under the hood.
We built ArkiaMate so the answers you receive carry her thinking — not a generic LLM with a custom voice glued on.
Persona LLM
Elena’s teaching style, examples, and criterion modeled into a system that stays in character. Her corrections, her phrasing, her sequencing.
Voice cloned
Her actual voice, captured and synthesized in real-time through ElevenLabs. Lip-synced to Arkia’s avatar shell.
Adaptive engine
Bayesian Knowledge Tracing infers what you’ve mastered and what you haven’t. Practice always meets you exactly where you are.
Longitudinal telemetry
Every session refines a personal mastery map. Friction patterns surface. Wins compound. You see the curve.
Voice + chat in one
Speak when it’s natural, type when it’s not. Switch in a tap. The avatar mode for presence; the chat mode for review.
Multi-expert ready
Built so any deep expert (not just Elena) can have a digital memory. Today: English. Tomorrow: more.
