30 days of Pro first.
Free for review markup, Plus for clean review sets with length and area, and Pro for full takeoff. Every account starts with 30 days of Pro, no card.
How much does Redline PDF cost?
Redline Free is $0 and covers review markup — clouds, callouts, text, stamps, pen and highlighter — with up to 3 saved drawings and a flattened PDF export. Redline Plus is $9 a month or $90 a year and adds clean and editable PDF exports, printing, page tools, the markup summary, revision comparison and calibrated length and area, with up to 25 drawings. Redline Pro is $15 a month or $150 a year and adds full takeoff — counts, volumes, deductions, Dynamic Fill, building elements, the CSV and estimates — editing the PDF itself, and unlimited drawings. Every plan has 2 GB of workspace storage. Every account begins with 30 days of Pro, no card. Then Free unless you choose Plus or Pro; your drawings stay.
Prices are US dollars and are the prices at checkout, which Paddle runs as merchant of record.

Which plan?
- You comment on a few sets now and then: Free. Review markup, 3 saved drawings, and a flattened PDF with a small footer.
- You review drawings and send clean sets back: Plus. Clean or editable PDFs, printing, the markup summary, revision comparison, and a quick calibrated length or area.
- You take quantities off drawings for estimates: Pro. Counts, volumes, deductions, building elements, the CSV and estimates, and editing the PDF itself.
Not sure yet? The trial is Pro, so you can use all of it on your own drawings before you choose.
What happens when the trial ends?
Nothing is charged, because no card was taken. Your account moves to Free unless you have chosen a plan, and every drawing stays where it is. If you made more than 3 during the trial you keep all of them and can go on editing them; Free only stops you adding another. Measurements and building elements you already placed stay on the sheet, and can still be moved or deleted.
How the price compares
| Tool | Per person, per year | Measurement, as the vendor describes it |
|---|---|---|
| Redline Plus | $90 | Calibrated length and area |
| Redline Pro | $150 | Calibrated takeoff with volumes, counts, deductions and Dynamic Fill |

Do I need a credit card to try Redline Pro?
No. The 30-day Pro trial takes no card and no billing details of any kind. Because nothing was taken, nothing can be charged when it ends: the account simply becomes Redline Free.
Can I change plans later?
Yes, from your workspace: between Plus and Pro in either direction, and between monthly and yearly billing. Paddle charges or credits the difference for the rest of the period straight away, so nothing is paid twice.
Can I cancel at any time?
Yes, from your workspace, and the cancellation takes effect at the end of the period you have already paid for. Billed time is not refunded, which is why the trial comes first and asks for nothing. The refunds page sets out the detail.
Is the yearly plan cheaper than paying monthly?
Yes. A year costs ten months: Pro is $150 a year against $180 paid monthly, and Plus $90 against $108. A plan is the same plan either way; nothing is held back from the monthly one.
Paying
Checkout is run by Paddle, who show the tax and the exact amount in your currency before you confirm anything. You can cancel from your workspace at any time. Billed time is not refunded, which is why the trial comes first and asks for nothing.
Try it on the sample drawing
Redline runs in the browser — nothing to install. Open the demo to try tools on a sample drawing. Demo edits are temporary; your own files, saving, signatures, exporting, printing and downloads come with an account, which starts with 30 days of Pro, no card. Then Free unless you choose Plus or Pro; your drawings stay. Plus is $9 a month or $90 a year; Pro is $15 a month or $150 a year. Compare the plans.
