How SERA fits into your day

From live troubleshooting to finished reports - and a community behind you

SERA isn't just another tool - it's a workflow. Start with a real problem on a real machine, get a guided troubleshooting plan, turn the result into structured documentation, and feed everything back into a community where knowledge actually stays.

Step 1 - Troubleshooting

Live troubleshooting - tailored to your machine

In SERA's troubleshooting view, you simply describe the machine, model, year and what is happening - SERA handles the rest. The assistant generates a step-by-step plan that is specific to that machine and those symptoms, instead of throwing generic "check the filter" advice at you.

You also tell SERA your experience level - beginner, intermediate or expert - and the guidance adapts to you. Newer technicians get clear, safe starting points and simple checks. Experienced techs get more advanced diagnostics, measurement suggestions and systematic "rule-out" logic. The goal is always the same: help you reach the root cause faster, without digging through hundreds of pages of PDF manuals.

Step 2 - Service protocols

Automatically generated service protocols - ready to use

In the service view, you enter the machine details and what kind of service is due - SERA builds a complete service protocol for you. You get a structured checklist of what to inspect, which filters and oils to change, and the correct volumes and specifications for each fluid.

The protocol is laid out like a real work order: clear bullet points, check-boxes, and logical grouping that makes it easy to work through on site. When you are done, it's ready to be saved, printed or attached to your existing documentation. The result is fewer missed steps, more consistent service quality and easier handovers between technicians and shifts.

Step 3 - Work orders

From diagnostics to a clean, professional work order

Once the fault is found and the work is done, SERA helps you turn that into a clear work order. You can either type a short description of what was done on the machine, or generate a work order directly from the troubleshooting chat. SERA condenses the entire conversation into a structured summary: complaint, root cause, actions taken, parts used and recommendations.

The result is a clean, readable document that actually reflects what happened on the job. It's easy to save, print or attach to your existing system, and it gives both technicians and customers a clear picture of what was done and why. Over time, your work orders become consistent, traceable and much easier to follow up on.

Step 4 - Community

Forum & community - where real-world experience lives

SERA's forum is where all the things that never make it into a manual actually live: real cases, odd symptoms, fixes that worked last time and lessons learned from the field. Here you can ask questions about a specific machine or fault, share how you solved a tricky problem, and bookmark threads you want to come back to.

The idea is simple: every time someone solves a hard fault, that knowledge shouldn't disappear when the job is done. Over time, your workshop builds up its own library of "this is how we fixed it" - a practical knowledge base that makes the whole team stronger, not just the one technician who was there that day.

Why we are building SERA

Our vision

Today, SERA is in its beta stage – not as a half-finished product, but as a living workshop. Our technicians and developers work side by side every day, feeding in new information, refining troubleshooting flows and making the experience as simple and reliable as possible for real technicians in the field. Every new case, every new machine model and every piece of feedback from users makes SERA a little bit smarter.

Our first clear goal is a stable, dependable application that holds up under real conditions – in the workshop, in the service van or out on site. SERA should feel like a natural part of the workday: fast to open, easy to understand, and smart enough to save time when it matters most.

Once we reach that level, we move into the next phase of our roadmap: building strong partnerships with machine manufacturers. With direct access to OEM knowledge bases, troubleshooting logic, schematics and up-to-date specifications, SERA can become dramatically more accurate. In practice, that means more precise recommendations, fewer guesses and repeated jobs, and diagnostics that follow the same logic the manufacturer uses internally.

In the long run, we see SERA as a natural bridge between workshops and manufacturers – where updates, campaigns, service bulletins and new insights don’t get stuck in PDFs or email threads, but become searchable and actionable exactly where the work happens.

This vision isn’t just a slide in a pitch deck. It’s what drives our day-to-day decisions – what we build first, how we design the interface, and how we train and evaluate our models. And we know one thing for sure: we won’t get there without our users. Your feedback, your bug reports, your “this is missing” and “this just saved my day” are what steer us in the right direction.

SERA is being built together with the people who actually turn the wrenches, take the measurements and solve the real problems. Our vision is to give you a tool that feels like a colleague – always available, always focused, and a little bit smarter than it was yesterday.
