Now in private beta
Your AI,unified, encrypted, free
One workspace across Groq, SambaNova, Cerebras, Gemini and OpenRouter. Bring your own free key, paste it once, chat with automatic failover.
how it works
Three steps to your own AI gateway
No subscription, no trial, no paywall. You bring the keys, we bring the unified experience.
Sign in and set a passphrase
Google, GitHub, or magic-link email. Then you set a passphrase that derives the key that encrypts your data. We never see it.
Paste one free provider key
Groq is the easiest. Grab a free key, paste it once. It is encrypted in your browser before anything reaches our database.
Chat with automatic failover
Smart, Fast, Reasoner, Live, Coder, Vision. If one provider is rate-limited, the next picks up. Your conversations are sealed end to end.
providers
Five free-tier providers, one gateway
Bring a key from any of these. Each one you add unlocks more modes and more headroom.

features
Honest, simple, fast
No fake metrics, no features that do not work yet. Here is what sarmalink actually does today.
Automatic failover
If your first provider is rate-limited or down, the next one in the ladder takes over mid-request. You see one continuous answer.
Six modes
Smart, Fast, Reasoner, Live, Coder, Vision. Each maps to a tuned engine and the providers it prefers.
Zero-knowledge vault
Your provider keys are encrypted with a passphrase only you hold. The server stores ciphertext, never plaintext.
Encrypted conversations
Every chat is sealed with your passphrase before it leaves your browser. We cannot read them, even if we wanted to.
Persisted chats
Conversations carry across devices. Sign in, unlock your vault, and your history is right where you left it.
Stop mid-stream
Cancel a long answer with one click. The next message starts a fresh context.
Dark and light
Theme switches with one click and follows your system preference by default.
One-click wipe
Delete a single conversation, export everything as JSON, or remove your account entirely from settings.
the security promise
Your keys, encrypted and never logged
The platform is built so that even we cannot read your plaintext keys.
- Your keys are encrypted at rest with AES-256-GCM, using a key derived from a passphrase only you hold.
- We never log your plaintext keys. They are decrypted in memory only inside the request handler that uses them.
- You can delete every key from your account with one button. The delete is irreversible and audited.
- Every chat request to a provider is signed end-to-end and logged with provider, latency, and model, never with payload.
