Rebuilt vs imported: what happens to your comment library when you switch

There are two words that get used like they mean the same thing when you switch inspection software. They do not. One is "import." The other is "rebuild." The gap between them is the difference between your reports still sounding like you and your reports sounding like a stranger wearing your name. This is the most important thing to understand before you move off Horizon.

What "import" means

Import means your actual comment library is carried over, word for word, exactly as you wrote it. The sentence you use for a worn roof is the same sentence, character for character, in the new software. Nothing is generated. Nothing is guessed. Your library shows up whole, and on day one your reports read exactly like they always did, because they are built from the same words.

What "rebuild" means

Rebuild is different, and the difference is easy to miss because it sounds just as helpful. Rebuild means the new tool does not take your words. It reads your old reports and generates a new comment library in its own style. Very often that style comes from a system trained on thousands of other inspectors' reports.

So what you get is not your voice moved. It is a new voice, built to resemble yours, shaped by a crowd of strangers. It might be close. It will not be you.

Why "close" is not good enough

Your wording is not decoration. You chose it on purpose, over years, and some of it you chose after a hard conversation with a client, an agent, or a lawyer. Your comments are careful for a reason.

When a system averages your voice together with 3,000 other inspectors, it sands off exactly those careful edges. The phrasing you use to stay accurate and stay safe gets replaced with phrasing that reads fine and means something slightly different. You will not catch every one of those. That is the danger.

The hidden cost of rebuild: the second job

Here is the part nobody puts in the offer. After a rebuild, you do not get to relax. You get a second job: reading the new AI-written comments, catching the ones that are wrong or not-quite-you, and fixing them, report after report, for weeks or months. You left Horizon to save time. A rebuild quietly hands that time right back.

Import does not have that second job. Your words are your words. You start where you left off.

The safety angle people skip

There is a safety difference too. A rebuilt or freshly generated comment is a comment you have not personally checked. A basic matching system can even do something worse: you say "no damage to the roof," and because it sees the word "damage," it pastes in a "damage observed" line. That single flipped comment is the kind of thing that gets an inspector sued.

Wording you imported is wording you already stand behind. That is not a small thing when your license and your name are on the report.

How to tell which one you are being offered

Offers rarely use the plain words. So translate for yourself:

When in doubt, ask: "Will my comment for a specific defect read the exact same after the move, word for word?" If the honest answer is no, that is a rebuild.

Where Mach One stands

We import. Full stop. Your comment library comes across in your exact words, unchanged, reading 7 common file types. There is no rebuild, no averaging, no second job. Your report sounds like you on day one, and it is built to tell "no damage" from "damage," so it does not just grab any comment with the word damage in it. Your library stays yours, and you can export and walk anytime.

Your software is shutting down. We import the library you spent years building.

Frequently asked questions

What does importing a comment library mean?

Import means your exact wording is carried over, word for word, unchanged. On day one your reports read like they always did, because they are built from the same words.

Is a rebuilt library as good as my own?

No. A rebuild generates new text in the tool's style, often from thousands of other inspectors' reports, so it sounds like an average of strangers and hands you weeks of fixing.

"I wish there was a means to save comments that I write in a reusable library." Is that what Mach One is?

Yes. Your library is the whole product. Every comment you have ever written, imported as written, reusable by voice. A Spectora user asked for this on Capterra in August 2025.

Hive and Spectora both added AI narrative writers. How is that different from importing?

They write new words based on your comments. Import leaves your words alone. InterNACHI inspectors in February 2026 said they were not impressed with either AI writer compared to their own text; that is the case for import.

"The standard comment lists were generally not satisfactory." Do I have to use stock comments?

No. Skip the stock list and bring yours. Mach One reads 7 common file types and imports your library in your exact words.
