Work types
01Platform
Three fields, one system
The same data does three jobs: it prices the project, trains the team and strengthens the price model.
02
Education
A classroom tool at universities, a teaching assistant for users, and open guides.
03
AI and neuroscience
The suggestion engine learns from past projects and updates itself using neuroevolution and neuroplasticity principles.
02Product
Enter takeoff however you work
Manual entry, automatic takeoff from room dimensions, calculation lines and Excel import — all in one place.
01
Takeoff from room dimensions
Enter room dimensions and wall, floor and ceiling quantities are calculated automatically, with openings deducted.

03Learning loop
The system learns with you
When you correct a price, or accept or reject a suggestion, the system records it. Over time, price ranges specific to your office take shape.

Feedback
How the system improves itself
- Neuroevolution — suggestion rules are tested against past projects and refined
- Neuroplasticity — price memory is reshaped by every correction you make
- Continual learning — the model stays current as new projects are added
Upload a PDF, Excel or scanned document and let the assistant draft the estimate. Nothing is saved without your approval.
- — Price suggestion with a confidence range
- — Missing item checks
- — Suggestions from similar projects
Research
Arkesif is also an open research project: we measure how accurate a learning cost system can be and publish the results.
By default your data improves the shared price model, and you can switch it off at any time. Each company's data is kept separate.

04Learning architecture
Learning inspired by neuroscience
Cost estimating is a memory and reinforcement problem. Arkesif models it with neurobiological principles.
- 01
Neuroplasticity
Synapses in use get stronger; unused ones weaken.
- 02
Neuroevolution
Variation and selection: structures that work are kept.
- 03
Hebbian reinforcement
Neurons that fire together wire together.
- 04
Reward prediction error
Dopamine reports the gap between what was expected and what happened.
- 05
Synaptic pruning
Rarely used connections are recycled; the network gets leaner.
- 06
Memory consolidation
Daily experience is replayed during sleep and written to long-term memory.
05Education
Education
It teaches and it learns: a tool for students, an assistant for users.
A tool for university teaching
Teach takeoff, cost estimating and pricing with real tools. Class workspaces, sample projects and assignment templates.
An assistant that teaches the user
Every suggestion explains its reason: what an item is, how a unit price is formed, why something looks missing.
Educational content and guides
Open guides on item analysis, cost literacy and takeoff practice.
University collaborations
An academic partnership programme for curriculum integration, joint research and student projects.
