Platform features

The Assistant

Ask questions in natural language. Yesper searches your project files, reference libraries, and Swedish construction databases — and gives you sourced, verified answers.

Upload any document — PDFs, blueprints, Excel, Word, PowerPoint, email (.eml/.msg), images. AI-powered OCR handles scanned documents and handwritten notes. Searchable within seconds with exact page and row citations.

Built-in AMA codes, BIP/BSAB discipline naming, Swedish construction standards. Automatic query expansion — 'ventilation' also searches VVS, V-ritningar, luftbehandling.

Unified search: project files, AMA, SGU, SMHI, Trafikverket, Naturvårdsverket, Lantmäteriet, web. Source attribution on every answer.

Systematically review deliverables against requirements and standards. Codify review processes as repeatable checklists you can run again. See how Brogrund AB cut tender review from three days to a coffee break.

Full canvas editor for collaborative writing with AI. Rich text, inline citations, version history. Export as Word or PDF with your branding.

SharePoint, Teams, OneDrive, Dalux. Government data from SGU, SMHI, Trafikverket, NVV, Lantmäteriet. Web search.

Talk to Yesper instead of typing. Transcribe whole meetings and working sessions: speech becomes text you can search, summarise and build on.

Set the work running.

Not just answers. Work, done. The mechanisms underneath that keep the platform running while you focus on what matters.

Automate full analyses as routines — sequential or parallel multi-step workflows that run on their own. Templates for procurement, compliance, and more included, or build your own. Background execution runs hour-long analyses in parallel with your work.

Yesper learns about your company and projects automatically. Scans documents, identifies phases, extracts key parties. Knowledge compounds over time.

Long-running tasks continue on the server. Automatic checkpointing, cost guardrails, graceful summaries if limits are reached. Resume anytime.

Have agents run tasks for you on a schedule. Weekly compliance checks, monthly KPI reports. Results delivered when each task completes.

Save any task as a prompt you can run again. Templates for common tasks included, or create your own. Share across personal, project, or workspace scope.

Turn a sequence of checks into a running checklist. Import a Word or Excel checklist and Yesper rebuilds it in minutes. Templates for common checks included, or create your own.

Generate documents from existing templates. Smart substitution preserves structure while updating project-specific details. Your organisation's shared template library is available in every project.

Beyond automation

Built around the work that's yours.

Pre-built agents cover what's common. The rest, we build for you on the platform. Calculations, interfaces, and tools shaped to how your work actually gets done.

Railway infrastructure map

A single inspection record can touch tracks, stations, ground type, wildlife barriers, today's weather, nearby work, even ÄTA status. We built an interactive map that brings all of it into one view — everything the team needs to do the job, without leaving the record.

Cut and fill calculations

On ground works projects, one of the first questions is how much to excavate and how much to fill. The answer shapes pricing and logistics from the start. We structured the underlying drawings and terrain data, then built a calculation layer that returns volumes by section with source references. Hours of section work done in minutes.

Bill of Quantities from IFC

An IFC model describes the building. A Bill of Quantities describes what gets procured and in what quantities. We built a pipeline that reads the model directly and returns a structured takeoff — grouped by discipline and element type, ready to cost or compare.
