The zero-knowledge AI your clients never have to worry about.

Encrypted chat, research agents, collaborative documents, and a full developer API — every response sealed with a key only you hold. A breach of our servers produces ciphertext, nothing more.

How it works

Three steps. No reading required.

1

Generate your key

An RSA-2048 keypair is generated in your browser. Your private key never leaves your device.

2

Choose a plan

Bring your own keys for any provider on Solo (5 supported), or use our managed Anthropic account on Starter and Business.

3

Chat encrypted to you

Responses are encrypted server-side with your public key. Only your private key can read them.

Capabilities

Everything a regulated team needs.

AI Agents

Research that cites itself.

Built-in agents handle the search loop server-side: Case Research queries CourtListener for binding opinions; Medical Literature pulls peer-reviewed studies from PubMed. You get a synthesized answer plus a clickable list of sources — every search query encrypted at rest.

Multi-step tool use loop with up to 8 iterations + forced synthesis pass
Streaming progress events: see "Searching CourtListener" mid-flight
Source cards encrypted to your key alongside the message

Canvas

Co-author documents in the same chat.

Open the canvas panel and the assistant writes directly into a Quill rich-text editor — encrypted Delta on every keystroke, edit history preserved. Drop a signature box, send to a recipient by email, and the signed image embeds back into the doc. Export as DOCX, signed and stamped.

Multi-signer support — invite peers, track per-signer status
Recipients sign without an Arcaveli account (token link)

BYOK · Solo plan

Five providers, one encrypted surface.

On the Solo plan you bring your own keys to any of the major frontier providers. Your key sits encrypted at rest with a server master key, decrypted only in memory for the duration of one request, and never logged. Switch providers per-conversation from the chat picker.

Workspaces · Business plan

Share a credit pool with up to 25 colleagues.

Business owners invite colleagues by email; each member's chats roll up to a single 25M-credit monthly pool. Members keep their own browser keypair — message contents stay encrypted to each individual user. The owner gets a workspace audit log: who sent how many tokens, by model, with no prompt content visible.

Owner / admin / member roles with revocable invitations
Members inherit Business access — their personal plan can be inactive
Owner cancellation freezes the workspace; data preserved on resub

Developer API

The same encryption, in your code.

Generate an API key from the dashboard, run onboarding once, and call the OpenAI-compatible /api/v1/chat/completions endpoint from anywhere. The official client library decrypts inline; the raw API returns ciphertext that any RSA-OAEP+AES-GCM implementation can unwrap. Same dual-keypair model as the web app — your existing chats keep working.

Node + Python quickstarts; raw HTTP works from any language
Streaming, agent loops, file uploads, canvas CRUD — full feature parity
60 requests/min/user, every response stamped with usage + cost

Questions

Everything we get asked.

No. Every response is encrypted with your RSA public key before it leaves our servers — only your private key can decrypt them. Web chats use your browser-held private key; the developer API uses a separate server-generated keypair you store yourself.

Your encrypted conversations become permanently unreadable. Back up your key to a password manager and an offline copy. We have no recovery path — that's the design.

Yes. Business plan customers can request a BAA from the dashboard — our compliance team sends it within one business day.

Yes. Each surface gets its own encryption keypair, so web chats and API calls live in separate encrypted histories on the same account, same plan, same billing.

On Solo: every model from Anthropic, OpenAI, Google, Groq, and OpenRouter (you bring keys). On Starter and Business: all Anthropic Claude models — Opus, Sonnet, and Haiku.

Each agent bundles a system prompt + a set of tools (CourtListener for case law, PubMed for medical literature). The model decides when to call them, the server runs the search, and the result feeds back into the next turn — up to 8 iterations. You see streaming progress events the whole time.

US-based infrastructure with encryption at rest. EU residency available on Business.

npm install arcaveli-client, generate an API key from the dashboard, run onboarding once, and call client.chat(). Or call /api/v1/chat/completions directly from any language. Read the full docs.
