Every feature, and who does the work.

Checks both uploads: drawn or scanned, page sizes, sheet count, title box found.

Code

Counts lines, words and pictures on every page, calls each page drawn, drawn with pictures, or scanned, and finds the title box.

You

You confirm the title box once per project.

Pairs old and new sheets, also renamed or renumbered ones, and lists new and dropped sheets.

Code

Reads the sheet number in the title box, then the title, then how alike the two pictures are. The printed number wins over page order.

Sheetshift AI

Reads the title box picture when the number is drawn as lines, and proposes pairs for renamed or renumbered sheets.

You

You confirm any pair Sheetshift AI proposed before changes are found on it.

Changes in lines, shapes and words, named by what they are: beam, column, slab edge, note.

Code

Lines the two sheets up, then compares every word with its place and every line and shape. Groups the raw differences into changes a person can read. Ignores the title box churn.

Sheetshift AI

Looks at the before and after pictures of each change, names it, and sorts it: design change, revision record, designer mark or plotting noise. It also writes out the old and the new words inside the change, table cells included.

You

Noise is never deleted. It sits in a folded group you can open.

Reads the designer's clouds and tags. Flags design changes nobody marked and clouds with nothing found.

Code

Finds the wavy outlines and the numbered triangles in the drawing, and links each change to the cloud it sits in.

Sheetshift AI

Confirms each cloud on a small picture of the sheet, finds clouds the shape test missed, and reads each tag's number.

You

A person looks at every cloud with no change found.

What the revision table says changed, against what did.

Code

Shows the change numbers behind every match. Nothing is merged or hidden.

Sheetshift AI

Reads the description of the revision, splits it into stated items and matches each one to the changes found. Lists what was said but not found, and found but not mentioned.

Details and sections on other sheets that may now be out of step.

Code

Finds references such as 3/S-501 near a change and says whether that sheet was revised in this issue.

Sheetshift AI

When the other sheet's words are available, checks whether its values still match the new value.

You

You decide whether to ask the designer.

One or two plain sentences per change, with the old and new values.

Code

Reads the place from the grid lines on the sheet. Every number, size and label in a note must be on the sheet, or the note is written again once, then replaced by the sheet's own words.

Sheetshift AI

Writes the note from the before and after pictures.

Which of your work packages a change may affect, why, and what to re-check.

Code

Only your project's own packages can be named. The wording is always may affect.

Sheetshift AI

Names the packages a change may affect and what to re-check. Never a cost, never a quantity it did not read on the sheet.

You

An Engineer confirms or rejects each link. Only then does the register say Confirmed.

The review queue, most important first.

Code

Orders the queue by that rank, then by sheet.

Sheetshift AI

Ranks each change High, Medium or Low with one short reason. Member sizes, levels, openings and removed elements rank high.

You

You can change any rank.

Fade, swipe, side by side, colour overlay, blink. Jump from change to change.

Code

Shows both sheets in the same coordinates, so change boxes and clouds line up exactly. Keys J and K move between changes.

Suggests the responsible team for each change. One click to accept.

Sheetshift AI

Suggests a team from the change's package links and what each team is responsible for.

You

You accept, change, or accept every suggestion on a sheet in one click.

Accept, ask the designer, needs an engineer, no effect, false alarm. Who, when and why.

Code

Records every decision with the name, the time and the reason, and keeps the history.

Only a person with the Engineer role can confirm an impact.

Code

Blocks sign-off for every other role. The register shows Confirmed by the engineer's name and their words.

A question to the designer with the crops and values attached.

Code

Attaches the crops and the change number, and checks every value in the draft against the change.

Sheetshift AI

Drafts the question with the sheet, the place, the old and new values and what your team needs to know.

You

You edit and send it. Sheetshift never sends anything by itself.

One list: export to Excel, CSV and PDF with crops, and share a read-only link.

Code

Filters by sheet, type, cloud status, package, team, decision and sign-off. Exports with the crops.

One page for each revision, and one short brief for each team.

Code

Counts and lists come from the change list, never from the writing.

Sheetshift AI

Writes the words around the numbers: what changed, what to check first, what nobody marked.

Ask a question about this revision and get an answer with change numbers.

Code

Counts and lists come from the change list. Questions outside your project are declined.

Sheetshift AI

Answers questions such as which changes may affect formwork, by asking the project's own change list.

Learns from your false alarms. Groups look-alikes and never hides them.

Code

Remembers what dismissed changes looked like in your project and groups similar ones on the next revision.

You

Everything stays openable. You can restore any change.
