Parabola vs. Relay.app

Relay.app blends AI steps with human approval inside lightweight workflows. Parabola runs fixed logic over operational data and routes exceptions to a queue someone works.

The short answer

Relay.app puts a person in the middle of the workflow. Parabola puts them at the end, on the exceptions.

Where humans fit
Relay.app is built around approval steps inside a run. Parabola decides everything it can and routes the rest to a queue.
Scale
Parabola is built for operational data volume rather than task-shaped workflows.
What runs each time
Logic fixed at build time, identical on every run, with each step inspectable.
Where Relay.app genuinely wins
Lightweight workflows that genuinely need a human approval in the middle.
Bottom line
Pick Relay.app when approval is part of the flow. Pick Parabola when volume means attention has to be spent only on what did not match.

Attention is the scarce resource

If a process runs a few times a day, pausing for a human to approve each one is reasonable. If it runs across 40,000 rows every morning, it is not — nobody approves 40,000 things.

Parabola is built on that assumption. The Flow applies the rules to everything, decides what it can decide, and produces an exception queue: the rows that did not reconcile, why each one is flagged, and what the recommended action is. Human attention goes to the small number of things that actually need it.

Which one is right for your team

Choose Relay.app when a person genuinely belongs in the middle of each run.

Choose Parabola when the volume is operational, the logic should be identical every time, and human judgement should be reserved for the exceptions.

Parabola vs. Relay.app FAQ

Where does Relay.app genuinely win?
+

Lightweight workflows where a human approval step belongs in the middle of the process, particularly around email and go-to-market tasks.

How does Parabola handle human judgement?
+

As an exception queue. The Flow processes everything it can decide deterministically and routes what it cannot to an Artifact where a person resolves the rows that need attention, rather than pausing every run for approval.

Which is better for recurring finance work?
+

Parabola, because the logic is fixed at build time and inspectable before it runs, it executes unattended on a schedule, and every step and row is traceable afterwards.
