Affordable
Built for efficient inference so routine questions stay cheap to serve — and realistic to price for real users.
Vivral by Nair Engineering
Private healthcare assistance.
Affordable. Intelligent. Equitable. A health assistant people can actually use — without cloud-scale costs or public data trails.
What Vivral is for
Clarity when it matters. Privacy by default.
Intelligent
Clear explanations for everyday health questions. Not a replacement for clinicians — a layer of understanding between searches and care.
Private
Health context stays with the user. Vivral organizes and explains; people decide what to share and with whom.
Private by default
Health questions should not feel public.
Users stay in control of what they add and what they share. Vivral explains and organizes; clinicians diagnose and treat. That separation keeps the product honest — and the experience calmer.

Investor case
Substantially cheaper to run.
Cloud-only healthcare AI pays again every time a user asks a question. Vivral is built around efficient inference so routine assistance can stay affordable for users and sustainable for the company as usage grows.
Every conversation rents expensive compute.
More engagement can mean more recurring serving cost, which pressures pricing and margin.
A lower cost curve from day one.
Efficient routine inference makes affordable subscription pricing and stronger margins realistic.
Better unit economics as usage grows.
Healthcare access only scales if the product can answer often without cloud-style cost drag.

Serving cost as monthly queries grow
Illustrative curves: cloud-only cost rises with every answer; Vivral stays on a flatter inference path.
