How TESSA works, step by step
TESSA is a mobile-first documentation assistant for biomedical and field service technicians. You capture the work as you do it; TESSA writes the report before you leave the room.
Included, free
Live label scanning
Your camera reads the manufacturer, model, and serial straight off the asset tag — including a wide-angle mode for tight equipment bays.
Smart compliance questions
TESSA asks context-aware YES/NO questions based on the device and whether the visit is a PM or a repair.
Photos and quick notes
Attach photos of the fault, the part, or the final state. They are stored with the session and used as context by the AI.
One session, from label scan to signed report
A TESSA session follows the same order as the job itself. You start a session, scan the equipment, log what you found and what you did, then generate the report. Everything auto-saves to your company workspace as you go, so a dropped signal or a locked phone never costs you the work.

How it works
- 1
Start a session and scan
Open TESSA on your phone, start a new service session, and scan the equipment label. Manufacturer, model, and serial populate automatically, and TESSA links the session to that asset history.
- 2
Document the work
Tag the issue and the action taken, answer the smart compliance questions, log labor time on a 0–8 hour slider, add photos and any notes. It all auto-saves.
- 3
Mark the outcome
Close the visit as Fixed or Needs Follow-up. If you recommended a replacement or a return visit, TESSA carries that into the summary.
- 4
Generate, review, send
TESSA writes the full report plus a short invoice summary. Review it, edit anything, then export the branded PDF or email it to the customer.
