About
A revised sheet arrives as a PDF. The designer clouds what they changed, or does not. Someone flips between two windows, or compares title box dates, or trusts that the cloud is the whole story.
Sheetshift started from one question: what would a checker look like if it worked the way a careful site engineer does? It compares the two sheets line by line, reads the old and new values, and writes down the differences it finds, whether or not the designer marked them.
Then it does the part that is usually left out: the bookkeeping. Who is responsible for this change, what was decided, and which engineer confirmed the impact. That list is the product. The overlay is how you look at it.
We price per active project, in naira first, with unlimited reviewers, because the people who need this are subcontractors and consultancies who cannot pay for a seat for everyone who needs to look.
Where it fits
Lay the old sheet over the new one in colour, so you see where the ink differs. You still write the list of what changed.
AI tools inside a wider construction platform, with the review of drawing changes as one tool among several.
Finds and explains the changes between two issued PDF sets, then keeps a review register: each change with an owner, a decision and an engineer's sign-off.
Read from the public product and pricing pages of each kind of tool.
