What does Chamfer AI do on a Windows PC?
Chamfer AI reads specs, drawings, submittals, and schedules that a reviewer chooses on that Windows PC.
Chamfer AI then drafts conflicts, RFIs, and reports from the files in that review.
A conflict draft is a note that two parts of the set do not say the same thing.
An RFI draft is a written question for a point the chosen documents do not answer.
A report draft gathers those items so a reviewer can read the items in one place.
Who has to review a Chamfer AI draft?
A qualified professional reviews every Chamfer AI draft before anyone treats that draft as final.
Chamfer AI does not replace a licensed engineer, architect, or attorney.
A Chamfer AI draft is not a permit, a stamp, a signed letter, or a direction to a crew.
The reviewer checks each quoted line against the original file before anyone acts on the line.
Where do the Chamfer AI project files stay?
The project files stay on the computer when a reviewer uses Chamfer AI.
Chamfer AI reads only the files the reviewer chooses for that review.
A file left out of the set is not read, and that file cannot appear in the draft.
The company site does not ask a visitor to create an account before reading how Chamfer AI works.
What does Chamfer AI cost, and how does a buyer install Chamfer AI?
Chamfer AI is free to download from the Microsoft Store.
A 7-day free trial comes next, and then the price is $49.99 a month.
A buyer installs Chamfer AI from the Microsoft Store without a sales call.

How does Trunk Tools describe the platform?
Trunk Tools describes the product as the AI platform built for construction.
Trunk Tools states that the platform is live on 1000 United States projects and is handling 50 billion dollars in construction volume.
The 1000 projects and the 50 billion dollars are Trunk Tools claims on the public pages, and Chamfer AI publishes no project count.
A reader should treat the 1,000 projects and the $50 billion as Trunk Tools statements, not as Chamfer AI results.
What price does Trunk Tools print?
Trunk Tools describes one price based on the buyer's construction volume.
Trunk Tools does not print a dollar number for that price on the public pages.
A reader of this comparison cannot quote a Trunk Tools dollar amount, because no amount was printed there.
Chamfer AI prints the price on this site, and the price is $49.99 a month after a 7-day free trial.
What comparison does Trunk Tools already publish?
Trunk Tools publishes comparison content, including a page on why Trunk Tools differs from general language models.
The Trunk Tools page compares the platform with general language models, and a buyer can read that comparison on the Trunk Tools site.
Chamfer AI now states its own difference in plain terms on this page.
Chamfer AI reads the chosen construction files on the PC, drafts the conflicts and questions, and leaves the judgment with a person.
What can this page say about Trunk Tools features?
The public Trunk Tools pages state the construction-volume price, the project claims, and the comparison with language models.
Seat counts, file types, and a cloud or desktop setup are not copied here unless a public page stated them in the lines above.
A claim about Trunk Tools that those pages did not state is left off this comparison on purpose.
A buyer who wants the volume price can read Trunk Tools and ask Trunk Tools for the number.
Which buyer is Chamfer AI for?
Chamfer AI is for a construction PM or estimator reviewing a document set.
Chamfer AI is not a DAW plugin, and Chamfer AI is not a comedy writer.
The unfinished studio tools on the company site are not for sale.
A buyer who needs a platform priced on construction volume can still read Trunk Tools and request that price.
How should a reviewer use a Chamfer AI draft?
A reviewer reads the Chamfer AI draft, checks each item against the named file, and then decides what to send.
A conflict draft becomes useful only after that person confirms both statements are in the set.
An RFI draft becomes a project question only after the reviewer edits the draft and chooses where the question goes.
A report draft becomes a project record only after that person accepts the lines that still hold up.
Where can a reader check the two products?
The Trunk Tools site is the public source for the volume price and the project claims above.
The Chamfer AI listing in the Microsoft Store is the public source for the download and the monthly price.
