> Verifiable private AI inference. LETHE is a chat and image-generation product with an OpenAI/Anthropic-compatible developer API, built on privacy that's structural, not promised.

  <Card title="Why LETHE exists" icon="flame" href="/why-lethe">
    Every AI request today leaves a paper trail: logged prompts, tied to an account, protected by a privacy policy you can't verify. LETHE is built on a different premise: privacy should be structural, not promised. Read the three-pillar case, and see honestly what's shipped versus what's still ahead.
