Agents that run the same UI procedure every time—no APIs, no improvisation. Built for mission-critical work where “mostly works” is not enough.
Talk to a HumanA clear definition of the category—and why it matters for production systems.
A deterministic agent is an agent that executes a defined procedure through the user interface the same way on every run. It does not invent steps. It does not answer differently when asked twice. It follows the process you recorded and composed—parameterized where needed, logged end to end—so the outcome is reliable enough for auditors, regulators, and production operations.
Stepwork builds deterministic agents from Procedures: reusable, parameterized sequences that chain UI flows into complete agentic processes with an auditable paper trail.
Same market conversation. Different guarantees.
| Dimension | Deterministic agents | Probabilistic AI agents |
|---|---|---|
| Execution | Same procedure path every run | Improvises; answers can vary |
| Interface | Runs through the real UI | Often prompt-, API-, or tool-driven |
| Audit | Reproducible paper trail | Hard to prove what happened |
| Best for | KYC, access, finance, ops | Summarization, ideation, open-ended Q&A |
| Risk posture | Auditor- and production-ready | “Mostly works” is the default |
Probabilistic models are powerful where creativity and language matter. Deterministic agents are what you put in front of production systems and auditors.
Record once. Compose Procedures. Run the same agentic process forever.
Show the work in the UI. Stepwork captures clicks, fields, and navigation into reusable flows—no API required.
Parameterize and chain flows into Procedures. String components together into end-to-end deterministic agentic processes.
Trigger on demand, from your ITSM, Slack, or a schedule. The agent follows the procedure—the same path every time.
Every action is logged and reproducible. You get the paper trail mission-critical work demands.
Where inconsistency is expensive—compliance, access, money, and identity—deterministic agents belong.
Repeat the same verification path across systems with a trail auditors can follow.
Provision and revoke access the same way every hire and every exit—no skipped steps.
Walk apps, collect evidence, and certify access with consistent, reproducible runs.
Close books-adjacent UI work with fixed procedures instead of improvised agent runs.
Ticket-driven admin work that must match policy every time, not almost every time.
Produce the same evidence collection path for SOC, ISO, and internal audits.
The first company to productize deterministic agents for real UI work—not another probabilistic agent tool.
Every automation vendor is selling probabilistic AI that mostly works. Deterministic execution you can put in front of auditors and production systems is the claim that separates Stepwork.
If a human can do it in the browser or desktop app, a Stepwork deterministic agent can run it—without SCIM, without waiting on vendor APIs.
Hybrid execution: deterministic procedure paths for the core work, with AI where it helps resilience—so you get reliability without giving up adaptability when UIs shift.
Runs in a hardened environment with MFA through your identity provider. Built for teams that cannot send sensitive ops to a black-box agent in the cloud.
Deterministic agents are software agents that execute a defined UI procedure the same way every time. They operate through the application interface—not APIs—and produce consistent, auditable results. Unlike probabilistic AI agents that improvise, deterministic agents follow the exact process you define, which makes them suitable for mission-critical work like KYC, onboarding, offboarding, user access reviews, and finance operations.
Most AI agents are probabilistic: the same prompt can produce different actions or answers on different runs. Deterministic agents run a fixed procedure path through the UI, so outcomes are repeatable and reviewable. Stepwork uses AI where it helps (for example, self-healing when UIs change) but keeps execution grounded in Procedures so the core path stays deterministic.
Deterministic agents are not the right tool for open-ended creative work—summarization, brainstorming, free-form writing, or tasks where variance is desirable. Those jobs fit probabilistic LLMs. Use deterministic agents when you need the same operational outcome every time and an audit trail you can show to compliance or security teams.
In Stepwork, you record real UI work into reusable flows, then compose those flows into Procedures—parameterized sequences anyone can call. Chaining Procedures creates end-to-end deterministic agentic processes with a visible history of every action. Procedures are the building blocks; deterministic agents are what you get when those procedures run reliably in production.
No. Stepwork deterministic agents operate through the UI the same way a trained human would—clicks, forms, navigation, and MFA included. That means you can automate apps without SCIM, without vendor APIs, and without waiting on engineering to build integrations.
Stepwork coined and productized the category of deterministic agents: UI-driven, non-API automation for mission-critical tasks, composed from Procedures with auditable paper trails. The category exists to separate reliable operational agents from probabilistic LLM tools that mostly work.
