Frequently Asked Questions
Can Praktika replace human tutors?
No—Praktika lacks cultural nuance and human interaction. It's best as a supplement for practice, not a replacement.
Is Lavern suitable for non-technical users?
Not really—it requires CLI installation (curl command) and local model management. Non-technical legal pros may struggle.
Does Praktika offer desktop access?
No—it's mobile-only. Desktop users should look elsewhere (e.g., Duolingo).
Does Lavern provide legal advice?
No—it's a document review tool. Users must verify outputs and should not treat it as a licensed attorney.
Is Lavern really free?
Yes—it's open-source under Apache 2.0. No subscription fees; you only pay for your own compute resources.
What languages does Praktika support?
Primarily English, but it offers a native language interface for beginners in many languages.
How does Lavern's adversarial debate work?
Agents with different roles argue both sides of an issue, citing evidence, then an orchestrator resolves the debate with cited findings.
Can I use Praktika offline?
No—it requires an internet connection for AI tutor interactions.
