Turn email chains, approval forms, and recurring busywork into auditable, automated pipelines. Mix AI reasoning, REST calls, MCP tools, approval gates, and human input — every run tracked, every approval logged. Built by non-developers, run by the business.

Every workflow is composed from these four step types. Sequence them, fan them out, route between them — whatever the process needs.
An LLM reasons over the prompt, input files, and prior step output. Attach Skills to give the step a domain vocabulary and live tool access. Returns structured JSON or free text. Choose any model per step.
Call any REST API, send email via ACS, or invoke any MCP tool. Templated bodies, JSONPath response extraction. The non-AI work that has to happen anyway.
Pause the pipeline until a human approves. Per-step participants, audit-trailed decisions with comments, deep-link emails to reviewers. Approvals are not optional — they’re first-class.
Collect values and files mid-flow. Field schema drives the form — text, number, checkbox, file uploads. For when the process genuinely needs a human in the loop.
Workflows kick off five different ways. Pick what fits the business process — a cron job for monthly reports, an email inbox for inbound RFIs, a webhook for system integrations.
Click "Start Run", upload files, watch the pipeline execute live. Initiator ACLs control who can launch.
Daily reports, weekly digests, monthly closes. Five-field cron with timezone support.
HMAC-verified inbound HTTP. Stripe-style or GitHub-style signatures. Idempotency-key support out of the box.
Each workflow gets its own inbound address like support-{alias}@email.nexilai.app. Subject, body, and attachments land in run.input and run.files[] automatically.
Poll any MCP tool every minute, fire a run on each new item. Built-in dedup via JSONPath cursor — perfect for "new Linear issue → triage workflow" flows.
The shapes real-world workflows take. Pick a template, or compose your own from the four step types above.
Steps run one after another. Invoice processing, report generation, data extraction.
Multiple branches process in parallel, results merge. Multi-document analysis at scale.
AI classifies input and routes to the right specialist branch automatically.
AI checks its own output quality and iterates until it meets your threshold.
An AI supervisor dynamically routes between specialist agents for complex tasks.
The hardest part of any workflow tool is the first run. We solved that two ways.
Don’t want to wire steps by hand? Type your workflow in plain English — "Process inbound RFIs: extract metadata, classify priority, route to the right engineer, send approval email" — and the AI generator produces a runnable config you can refine. Skip the empty-builder problem entirely.
Test the workflow you’re editing without leaving the page — one click runs it end-to-end against a sandbox tenant, returns every step’s output inline, and auto-cleans up after. No polluting prod analytics with test data.
Pick from a library of starter workflows, or build your own visually. Every run is auditable, every approval is tracked, and every participant has a single inbox of what’s waiting on them.
X-Idempotency-Key so retries don’t double-fire
Timeouts, retries, retention, alerting — production reliability isn’t bolted on, it’s the default.
Per-step timeouts and configurable retry with backoff. Transient API blips don’t fail your run.
When a step needs human attention, participants get an email with a deep link — no more lost approvals.
Per-tenant tokens-per-minute caps prevent any one workflow from starving the rest. 429s with retry-after.
Find any run by status, date, or free-text. Debounced search across hundreds of runs.
Terminal-state runs older than 90 days are pruned daily — predictable storage, predictable cost.
MTD LLM spend vs tier allowance, projected end-of-month, alerts at 75/100/150% — in-portal and email.
The processes our customers run on autopilot — tracked, approved, audited, repeatable.
Email arrives → AI extracts vendor + amount + line items → approval gate at >$5k → auto-post to accounting via MCP. Audit trail every step.
Cron-triggered every Monday → AI pulls RFIs from SharePoint → summarises blockers → emails project leads with deep links to the source docs.
HR uploads candidate batch → AI redacts name, age, photo, gender markers → manual review gate → redacted PDFs land in the hiring SharePoint.
DocuSign webhook fires → AI checks the executed contract against the playbook → flags exceptions → routes to legal if anything unusual.
Email inbox trigger → AI classifies (priority, category, owner) → opens a ticket via Linear MCP → replies to the user with the ticket link.
Application uploads → AI scores against the rubric → multi-reviewer approval gate → decision email with rubric breakdown attached.
