Hosted Service

Don't want to self-host? concierge.calculon.tech runs this exact stack as a managed service. Sign up, connect your channels, and start auto-replying in minutes. 100 free replies every month.

Features

• WhatsApp Auto-Reply: rule-routed canned or AI replies via Meta Business API
• Instagram DM Auto-Reply: connect your business account, reply automatically
• Reply Rules: per-channel ordered rules (keyword matchers and embedding-based intent matchers), each routing to canned text or an AI prompt; mandatory default fallback per channel
• Persona Builder: tenant-wide AI persona via guided builder (voice archetype, business name + type, goal, catch-phrases, off-topic boundaries, handoff conditions), curated archetype copied from a platform-managed D1 catalog, or raw prompt. Every change is run past a safety classifier asynchronously via Cloudflare Queues; AI replies stay blocked tenant-wide until the new prompt is approved
• Prompt Envelope: every AI reply is wrapped by a fixed preamble + postamble (defined in src/prompt.rs) that establishes the operating manual, jailbreak rails, and the universal handoff sentinel. Tenant content lives in the editable middle and never reaches the model alone
• Conversation Sessions: per-customer threads carry a stable conversation_id, recent message history, and any active handoff state. A configurable idle gap (default 6 h) wipes history and starts a fresh conversation; a configurable max-history-messages cap (default 20) bounds the multi-turn context fed to the AI
• Human Handoff: the model can flag a turn with [[HANDOFF]] (universal triggers in the postamble + tenant-specific conditions in the persona). The pipeline strips the token, switches to a holding-pattern voice for follow-ups within the cooldown (default 60 min), then goes silent. The tenant is paged once via the existing approval-notification channels (Discord embed and/or immediate email)
• Live Demo Chat: the public welcome page hosts an interactive demo where visitors roleplay as a customer of a sample business and see the AI reply in real time. Persona picker pulls from the safety-approved D1 archetype catalog; a "View prompt" panel reveals the exact envelope being sent to the model. Real customer messages still arrive on WhatsApp / IG / email / Discord — never on this chat box
• Managed Email Subdomains: each tenant gets *.cncg.email addresses with smart routing rules (glob patterns). Forward, drop, AI-draft, or relay to Discord. MX records provisioned automatically via Cloudflare API
• Discord Relay: unified inbox. Messages from any channel land in Discord with Reply/Approve/Drop buttons. Reply in Discord and it flows back to the customer
• Lead Capture Forms: embeddable phone number forms that trigger WhatsApp messages
• Onboarding Wizard: guided setup (business info, channels, notifications, persona archetype, billing)
• Notification Preferences: configurable approval + digest delivery via Discord and/or Email with batching frequency
• Localized: per-tenant BCP-47 locale (en-IN and en-US shipped) drives Indian-vs-Western number grouping (₹1,00,000 vs $100,000) via icu4x; translation backbone uses fluent-rs FTL files for drop-in new languages. AI-generated reply content stays English regardless of UI locale
• Management Panel: Cloudflare Access-protected admin for tenant management, billing, audit log
• Billing: flat prepaid credits (₹0.10 / $0.001 per AI reply, 100 included every month). Static auto-replies don't consume credits. Buy any quantity (slider, no tiers, no packs). Reply-email subscription: 5 addresses per ₹99 / $1 per month. All prices live in global_settings and are editable from the management panel
• Metadata-only logging: message bodies pass through the Worker but are never written to durable storage. Only channel, direction, sender, recipient, and timestamp are persisted. A /data-deletion endpoint wipes the metadata that is stored.

Deploy

See the Deploy guide for step-by-step instructions on forking and deploying your own instance to Cloudflare.

CI/CD is handled by Cloudflare Builds (Workers CI), which builds and deploys directly from this repo without needing GitHub Actions or Nix.

To wire up your fork:

1. In the Cloudflare dashboard, create a Worker named (e.g.) concierge and connect this repo under Settings → Builds.
   • Build command: leave default (CF Builds runs npm install from package.json)
   • Deploy command: npm run deploy (defined in package.json; installs worker-build then runs wrangler deploy)
2. Bind a D1 database (DB), KV namespace (KV), Workers AI (AI), Email Routing send-binding (EMAIL), Durable Objects (REPLY_BUFFER → ReplyBufferDO, APPROVALS_DO → ApprovalsDO), and Queues (SAFETY_QUEUE producer + concierge-safety / concierge-safety-dlq consumers) under Settings → Bindings. Names must match the binding values in wrangler.toml.
3. Set runtime variables and secrets under Settings → Variables and Secrets. The full list is documented at the bottom of wrangler.toml.
4. Push to main. Cloudflare Builds runs the build command, then wrangler deploy, which picks up [build] command = "worker-build --release" from wrangler.toml to compile the Rust crate to WASM.

Architecture

• Cloudflare Workers (Rust compiled to WebAssembly)
• Cloudflare D1 (SQLite for metadata logs and billing)
• Cloudflare KV (account configs, sessions, billing state)
• Cloudflare Workers AI (AI auto-replies)
• Cloudflare Email Routing (inbound email handling)
• Cloudflare Email Service (outbound delivery to arbitrary recipients via the send_email binding's structured API)
• Meta WhatsApp Business API + Instagram Graph API
• Discord Interactions API (slash commands + cross-channel relay)
• Razorpay (one-shot credit purchases + email subdomain subscriptions)

Development

nix develop        # enter dev shell with all tools (Nix-only; CI does not use Nix)
cargo test         # run tests
wrangler dev       # local dev server
wrangler deploy    # deploy to Cloudflare

Nix is for local convenience only. Cloudflare Builds installs the same toolchain via rustup, which reads the channel from rust-toolchain.toml.
