Why the preview carries a watermark
A watermark is a fair trade for a free preview. It lets you build the entire document, check every field position, print a rough copy to see how it reads on paper, and change your mind as often as you like, without anyone having to meter it. What you cannot do is hand the watermarked file to someone else as a finished document.
When the document is right, one credit clears the watermark. A twelve-page lease packet and a single-page receipt each cost that same one credit, because the unit here is the document, not the page.
What you can do for free
Upload a PDF up to 25MB, or start from a template. Add text, checkbox, date and signature fields. Choose Letter, Legal or A4. Pick a style set and one of eleven typefaces. Add a logo. Reorder, duplicate and delete pages. Paste a list of line items instead of typing them one at a time. Preview every page with the watermark.
Answers you type are kept on the device you are working on, so you can close the tab and come back to the same draft. Signed-in visitors get the same library synced across devices.
What costs a credit
Exactly one thing: the clean download. One credit per document, no matter how many pages. Credits are sold in one-time packs, from a single document to fifty, and they never expire, so a pack bought for one busy week is still usable next year.
There is no subscription, no renewal, no trial that converts into a charge, and no export that quietly burns a credit in the background. If a download is interrupted, the credit is not spent twice.
Limits that keep the service usable
Free building is rate limited so one person cannot occupy the whole machine. A visitor without an account can finalize three documents a day, a free account ten, and a purchaser fifty, counted to the day boundary at midnight Central Time. Finalizing is also held to one per minute.
Drafts are cleaned up on a schedule that is shown on every saved document. Visitors without an account see their watermarked drafts removed 14 days after creation, which is enough time to finish a document and not long enough to accumulate someone else's personal information indefinitely.
Build it, preview it free, pay once for the clean copy
Nothing here needs an account. You build the document, preview it with a watermark, and spend one credit only when you download the clean file. Credits never expire.
