    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.

    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.

    What you get

    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.

    AI-written report

    Findings, actions taken, parts used, and outcome are written into a structured, professional service report.

    Edit or refine

    Change any line yourself, or ask TESSA to rewrite a section. The report is yours until you send it.

    Branded export and email

    Export a branded PDF with your company logo and colors, or email a secure link straight from the field.

    How it works

    1. 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. 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. 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. 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.
