One stack, two modes

Lemka adapts to what the deployment can risk getting wrong.

Generative

Open conversation

Lemka generates a response in context; for agents, assistants, and voice tools where natural back-and-forth matters more than a fixed script.

Voice agents
Field tools
Internal use

Best fit

Deployments where a flexible, conversational answer is more valuable than a guaranteed-verbatim one; and where a human is in the loop to catch the edge cases.

Extractive

Document-grounded, zero hallucination

Lemka retrieves the answer directly from your source documents and reads it back; no generation, no invented content, fully auditable.
Govt helplines
Public services
High-stake deployments

Best fit

Public-facing and government deployments, where every spoken answer needs to be traceable back to an approved document

Built around real deployments

Voice helplines

A caller speaks in Khasi, Garo, or Mizo; Lemka answers from an approved document set, no call-center script needed.

Field advisory tools

Offline-friendly voice access to agricultural and community guidance, in the language people already speak at home.

Government services

Extractive mode gives departments a spoken interface they can approve; every answer sourced, nothing improvised.

Seven languages, built from the ground up

Khasi
Garo
Mizo
Kokborok
Assamese
Nagamese
Meitei

Self-hosted, not an API

Lemka is deployed as part of a full pipeline built for your channel; not sold as open access.

Scope the channel

IVR line, kiosk, or field app; we design around where the voice actually happens.

Choose the mode

Generative for open use, extractive for anything public-facing or high-stakes.

Deploy on your infrastructure

Lemka runs self-hosted; your data, your servers, your control.
