Gravity Rail is the full-stack platform for conversational AI. Voice, chat, SMS, email, phone, EHR — one unified system with enterprise security built in.
Every feature below works together. Connect a channel, configure an AI assistant, wire up a workflow, and your agent is live — across every channel, with full audit trails and HIPAA compliance.
Reach your users wherever they are — every channel runs the same AI workflows.
Launch branded web portals and embeddable chat widgets. Configure public or private access, custom domains, self-signup, and themes — deploy AI chat on any website with a single script tag.
Build AI-powered phone systems with real-time speech synthesis and recognition. Route calls through intelligent IVR trees, transfer to humans, and record conversations with full transcription.
Send and receive AI-powered text messages through Twilio. Automate outreach campaigns, appointment reminders, and two-way conversational SMS from any workflow.
Connect email addresses as AI-powered inboxes. Automatically classify, route, and respond to inbound email while maintaining full audit trails and thread context.
Provision local and toll-free phone numbers directly in your workspace. Assign them to workflows for voice calls and SMS, with automatic carrier compliance built in.
Deploy AI assistants as Discord bots with slash commands, DM support, and full thread context. Members interact naturally in their existing Discord servers.
Configure how your AI thinks, who it talks to, and what it can do.
Configure the AI personalities powering your conversations. Choose models (Claude, GPT, Gemini), set identity prompts, attach knowledge sources, enable tools, and fine-tune behavior for each use case.
Create autonomous agent members that work alongside humans. Agents can be assigned tasks, participate in workflows, take actions using tools, and escalate to human operators when needed.
Manage the people in your workspace — patients, customers, employees, or any user type. Import from external systems, assign roles, track engagement, and control access with RBAC permissions.
The core of every interaction. Chats support AI-assisted messaging across all channels with shared context, conversation history, human handoff, and full message audit trails.
Give your AI the context it needs — structured data, documents, calendars, and metadata.
Define custom data structures for your domain — patient records, product catalogs, CRM entries. Typed fields, validation, search indexing, and bulk import/export via API or CSV.
Upload and manage documents, images, and media. Files are automatically indexed for AI retrieval, enabling assistants to reference your knowledge base in real-time conversations.
Two-way calendar sync with Google Calendar. Import availability, create events from workflows, and let AI assistants schedule appointments on behalf of members automatically.
Organize members, chats, and records with flexible labels. Use them to segment audiences, route conversations, trigger automations, and build filtered views across your workspace.
Wire up triggers, workflows, and schedules so your AI runs on autopilot.
Design structured conversation flows that guide AI behavior. Assign tasks, route between channels, attach tools, and define the steps your assistants follow — from intake to resolution.
Trigger automated actions when things happen — new email, chat message, task update, or record change. Chain rules together for multi-step automations across your workspace.
Push real-time event notifications to your systems. Receive structured JSON payloads for messages, tasks, records, and workflow events — ideal for syncing with external tools and pipelines.
Automate time-based actions — send follow-up messages, expire assignments, run periodic reports. Define one-time or recurring schedules with cron expressions.
Everything you need to integrate programmatically, from REST to LLM protocols.
170+ endpoints covering every workspace resource. Create chats, manage members, import data, configure workflows — everything the UI can do, the API can do programmatically. TypeScript SDK and CLI included.
Connect Claude and other LLMs directly to your workspace via Model Context Protocol. Enable AI tools to read data, trigger actions, and manage resources on behalf of users — no custom integration code needed.
Secure API access with API keys for server-to-server integration, or OAuth 2.0 for user-authorized third-party apps. Scoped permissions ensure least-privilege access to workspace resources.
Connect to FHIR-compatible EHR systems like eClinicalWorks and athenahealth. Pull patient context, sync appointments, and automate clinical workflows — all with HIPAA-compliant data handling.
