Epsilon Streamlines Procedure Management with Powerful Features
Reviewed on Jan 13, 2026
Review provided by G2
What do you like best about the product?
Epsilon is a great way to organize, store, and create procedures for use in a larger and scaling organization. There is easy access and split permissions to ensure only select individuals are able to create and edit procedures. The filtering and search systems are fantastic. The ability to upload pictures and files is a huge help to each process. The archive of completed or ended procedures ensures that no data is ever lost. There are constantly new features being released that allow us to improve our processes all the time, and expand the information we can capture. Getting the procedures transferred over and integrated into our manufacturing processes has overall saved us plenty of time and effort. Even from the initial implementation, it was easy for the procedure creators to get up to speed and start releasing usable procedures.
Huge positive is that the entire Epsilon team is incredibly responsive, and even the AI help tool does a fantastic job at getting the correct information for my questions or concerns.

What do you dislike about the product?
There are times that Epsilon gets a little cumbersome or confusing, especially when trying to pass ideas on to technicians or users who are not as familiar with the interface. When asking for updated or new features, there can sometimes be a long lead time on those coming to a usable state. Certain features have been changed that were working great, and for some reason got an update to the point that they were no longer useful. Sometimes there are ideas that seem like they should be feasible or easy to accomplish, and it ends up that Epsilon is too limited in its scope, such as creating separate paths of workflows, or even being able to choose which part from inventory you would like to reference in a procedure.

What problems is the product solving and how is that benefiting you?
Epsilon3 solves the challenge of managing complex, high-risk operational procedures that were traditionally tracked using spreadsheets, PDFs, or paper. For teams working in aerospace, defense, or advanced manufacturing, this often leads to version control issues, manual errors, and poor traceability.
