Construction runs on conversations. Now they’re documented.
Your calls and site walks become daily logs, RFIs, and punch items automatically. For supers, PMs, and owners who run the job from their phone.
Construction teams running their calls through Hardline








40 calls a day. 20+ on site conversations. Hundreds of decisions.
And somehow the Super and PM are
supposed to remember it all
Most of the job never gets written down
of project decisions happen verbally
of rework traces back to undocumented decisions
of what actually happens onsite gets documented
Every decision that matters happens on a phone call, site walk, or field conversation. Then it disappears.
Now, the job documents itself.
You talk. Hardline turns every call, site walk, and field conversation into the documentation, tasks, and updates your team needs.

Who it’s for
Superintendents
You take 70 to 100 calls a day and the paperwork for all of them was waiting for you at night. Now you make your calls like usual, and Hardline writes the daily log, the RFI follow-up, the punch item. Nothing new to learn. One super logged 86 calls his first day without training.
Project managers
You spend your week chasing what happened: calling the super back, reconciling texts, filling gaps in Procore. Hardline writes the record as the day happens, so the log, the tasks, and the open items are already there when you look. Less chasing, fewer surprises at the OAC meeting.
Owners and operators
One undocumented call can cost six figures. Every verbal change and T&M authorization is documented the second it’s said, timestamped, and searchable. When the dispute comes, you have the record and the other side has a recollection.
Subcontractors
The extra work you did on a verbal say-so is the extra work you don’t get paid for. Hardline documents the change, the approval, and the date, in writing, the moment it’s spoken. That’s entitlement you can take to the GC.
Office teams
Not everything gets decided in the field. Hardline for Mac takes notes in your Zoom, Google Meet, and Microsoft Teams meetings, into the same record as the calls and the site walks. The OAC meeting and the call from the truck end up in one place.
From the people on the phone

“I logged 28 hours of calls last month and nothing slipped through the cracks. My office team stays in the loop without me repeating myself. That info used to just vanish.”
“I was doing my journals for 45 minutes at the end of every day. Now I just do my walkthrough, snap photos, and talk, and it captures all the little things from my calls too.”
“I love this app, it works incredibly well for us construction people”
One undocumented call can cost six figures.
52% of rework comes from undocumented decisions. The fix is setting it up once. Then the day documents itself.
Questions builders ask
What is Hardline?
Hardline is an all-in-one jobsite documentation app for construction, and the only one that captures your phone calls. It turns calls, site walks, photos, and videos into structured project records: daily logs, RFIs, punch items, tasks, change orders, and meeting minutes. Photo apps show what the site looked like. Hardline captures that too, plus the phone calls where the decisions actually get made, and ties the photo or video to the conversation that explains it. You make your calls like usual and the documentation writes itself. No typing, no new app for the crew, no behavior change. Outputs sync to the tools you already run, including Procore, Autodesk Forma (formerly Autodesk Construction Cloud), and Fieldwire.
What's the best AI voice app for construction?
Hardline. It's a voice app built specifically for construction field teams, not a general assistant repurposed for the jobsite. It takes notes on your inbound and outbound phone calls and on-site conversations, then turns them into daily logs, RFIs, punch lists, tasks, and change orders that route into Procore, Autodesk Forma, and Fieldwire. No typing, no new habits, no call audio stored.
What problem does Hardline solve?
Most jobsite decisions happen on the phone, and almost none of it gets written down. The spec change, the sub's Thursday commitment, the owner's approval on the window: said out loud, then gone. Construction loses an estimated $177B a year to miscommunication, and roughly half of all rework traces back to it. Hardline creates an automatic written record of every work conversation as it happens, so the decision exists in writing before anyone has to remember it.
Who is Hardline built for?
Superintendents, project managers, project engineers, and foremen who run their day on the phone, and the GCs and trade contractors they work for. Hardline works across residential, commercial, and specialty/sub-trade construction. If your business lives in your phone and your crew is never going to adopt another app, Hardline is built for you.
What devices does Hardline work on?
Hardline runs on iPhone, iPad, and Android, with a Mac app and a web app for the desk. Download it from the Apple App Store or Google Play and sign in with your existing number. There's no hardware to buy, no dongle, no headset. The capture happens on the phone you already carry all day.
How do I get started?
Download Hardline from the Apple App Store or Google Play, or book a demo at hardlineapp.com. Most teams are up and running the same day. All you need is a smartphone. No special hardware, no IT setup, no procurement process.
