Design, test, and deploy AI workflows visually
A drag-and-drop canvas for building complex AI automation — triggers, AI nodes, branching logic, agents, and tools, all connected visually and deployed in one click.
Build workflows with natural language
Describe what you need and MetaBuilder generates a complete workflow — then iterate conversationally until it's perfect.
- ✓End-to-end workflow generation from a single prompt
- ✓Conversational iteration — refine steps in natural language
- ✓Automatic issue detection and suggested fixes
Measure and improve every interaction
Define northstars, run adversarial tests, and let automated audits catch regressions — so quality scales with your workflows.
- ✓Northstar criteria — define behavioral quality standards for every agent
- ✓Automated LLM audits that flag regressions before customers notice
- ✓Adversarial test agents that stress-test edge cases on every deploy
- ✓Issue tracking from detection to resolution, auto-generated from failures
Test changes against live traffic
Run A/B tests on workflow variants with real traffic, then let built-in statistical analysis tell you which version wins — no guesswork, no manual spreadsheets.
- ✓A/B testing with traffic splitting — route runs to variant configurations and measure impact
- ✓Config overrides — test prompt changes, thresholds, and API params without new versions
- ✓Built-in statistical analysis — point estimates, confidence intervals, p-values, and effect sizes
- ✓Default + custom metrics — track northstar pass rates, voice metrics, or define your own expressions
Start workflows from any signal
Eight built-in trigger types let you launch automation from calls, messages, webhooks, file uploads, and schedules.
Webhook / API
Trigger workflows from any external system via HTTP.
Inbound Phone Call
Kick off automation the moment a call comes in.
Parse incoming emails and route them to the right workflow.
SMS
React to text messages in real time.
Slack
Start workflows from Slack messages or slash commands.
Microsoft Teams
Integrate directly with Teams channels and bots.
File Upload
Process documents, images, and data files on arrival.
Schedule
Run workflows on a recurring cron or one-time schedule.
Extract, classify, and generate with AI
Purpose-built AI nodes that handle the most common intelligence tasks — no prompt engineering required.
- ✓AI Extract — pull structured data from unstructured text, documents, and images
- ✓AI Classify — categorize inputs into predefined or dynamic label sets
- ✓AI Generate — create text, summaries, translations, and structured responses

Drop into code for custom logic, hit any API, or process files — without leaving the visual builder.
- ✓Custom Code — write JavaScript or Python inline for any transformation
- ✓Webhook — call external APIs and parse responses back into the workflow
- ✓File Operations — read, write, transform, and route files of any format
Voice and text agents at every touchpoint
Deploy conversational agents across every channel — powered by the same workflows you build on the canvas.
Voice Agents
50+ languages with a real-time STT → LLM → TTS pipeline. Sub-second latency for natural conversations.
Inbound
Answer calls and resolve issues autonomously.
Outbound
Make calls to customers, leads, and partners.
Callback
Schedule and execute follow-up calls automatically.
Text Agents
Unified agent logic across every text channel — same workflow, every surface.
SMS
Two-way text conversations.
Rich messaging with media.
Read, draft, and send emails.
Chatbot
Embed in any web app.
Teams
Native Microsoft Teams bot.
Slack
Respond in channels and DMs.
Give agents the right tools for the job
Equip your agents with custom functions, built-in integrations, and MCP-compatible tool servers.
- ✓Custom tools — define any function your agents can call at runtime
- ✓Built-in tools — TMS lookup, rate quoting, document parsing, and more
- ✓MCP tools — connect to Model Context Protocol servers for extensible capabilities
Ship with confidence
Draft, review, and promote changes through isolated environments with full version history and one-click rollback.
- ✓Draft / Published versions — edit safely without affecting live workflows
- ✓Three environments — develop in dev, validate in staging, ship to production
- ✓Approval workflows & rollback — require sign-off before deploy, one-click rollback if needed
