Workflow Builder

Automate any Process Visually

The operating system for building, deploying, and governing production-grade AI agents

SimplAI Workflow Builder Interface
YOUR PATH

From idea to production - on one OS

Build, ground, test, deploy, and improve AI agents without stitching together
a fragmented stack.

1

Define Your Agent

LLM, instructions, knowledge, tools, guardrails - set your agent's identity on the canvas.

2

Expand Capabilities

Flip the toggles that matter - memory, citations, voice, reflection, file uploads, browser.

3

Test & Refine

Run test datasets, inspect evaluation scores, preview every version before promoting it.

4

Deploy & Monitor

Publish to API, webhook, embed, or A2A. Watch run history in real time. Export data.

5

Iterate & Scale

Continuous evaluation catches regressions. Version control owns every release. Sub-agents scale infinitely.

The Core Builder

Your entire process,
drawn on one screen.

The Workflow Builder canvas is where complexity becomes clarity. Every node is a step, every line is a decision. You see the whole automation at a glance - and change it just as fast.

🎯
Visual building
Map the full workflow on one canvas so logic, branching, and dependencies stay visible as automation grows more complex.
Fast iteration
Test step by step, inspect outputs beside each node, and refine flows without rerunning the entire workflow every time.
🔗
Built to connect
Use pre-built integrations, HTTP requests, and reusable credentials to connect the tools, data, and systems your workflow depends on.
🤖
Agentic execution
Add AI-powered steps anywhere in the flow so workflows can reason, generate, classify, summarize, and take action as part of the process.
🔀
Flow control
Route, merge, loop, filter, and transform data so workflows can handle real-world branching, exceptions, and operational complexity.

50+ Pre-Built Steps

Every tool your workflow
will ever need.

Stop building connectors from scratch. Pick from a library of pre-built nodes across 25+ categories - and wire them into your flow in seconds.

🤖
AI & Reasoning
Run LLM calls, generate embeddings, translate content, create images, and execute Python - the building blocks of intelligent automation.

Agentic Node Controls

Every node is smarter
than it looks.

Execution rules, guardrails, retry logic, and error handling - baked into every single node. Not bolted on afterward.

🔄
Foreach Loops
Run any node over a list automatically. Process a hundred records the same way you'd process one. No extra code.
Execution RuleList Processing
Trigger Rules & Conditions
Define exactly when a node runs. Set conditions on upstream outputs - skip steps that aren't needed, branch into parallel paths.
Conditional LogicBranching
🛡️
Guardrails
Attach validators to any LLM node. Block toxic outputs, enforce format, and keep your workflows safe before results leave the step.
LLM SafetyOutput Validation
↩️
Retry on Failure
Toggle automatic retries per node. Set limits, define backoff - your workflows keep running even when third-party APIs hiccup.
ReliabilityResilience
🔴
Error Handling
Choose what happens when a node fails: stop the workflow, continue with error, use a fallback value, or fail only that branch.
Stop WorkflowFallback ValueFail Branch
🔬
Scale & Burst
Click any node to see exactly what happened on its last execution. Inputs, outputs, latency, errors - full transparency, no guessing.
ObservabilityDebug
Deployment

Deploy AI agents anywhere
Zero compromise.

Expose agents through APIs, webhooks, embedded widgets, MCP, and
future interfaces – without changing how they run.

Test & Evaluate

Test it before
the world does.

Two quality layers, working together. Test Datasets let you run structured evaluations before launch. Evaluate runs continuously after - catching regressions before your users do.

✏️
Test Datasets - pre-launch
Run your agent against a curated dataset. Use AI to generate test cases, set evaluator criteria (accuracy, structure, completeness), and measure before you ship.
📈
Evaluate - continuous quality
Point the evaluator at past or future conversations. Get average, min, and max scores across thousands of traces - automatically.
🔬
Custom evaluators
Build scoring criteria specific to your use case - tone, policy compliance, factual accuracy. Your domain, your rubric.
Versioning

Every release,
under your control.

Label, preview, promote, and roll back any agent release with confidence – without losing visibility over what changed, when, and why.

📤
Publish with confidence
Give every release a name and changelog. Your team knows exactly what changed and when.
Instant rollback
Promote any previous version to production in one click. Production incident? Fixed in under 30 seconds.
👁
Preview before you publish
Chat live with any version before setting it as latest. Ship what you've tested - not what you hope works.
