Text extraction is the feature that scanner apps ration, because it is the feature worth charging for. The free part is usually a picture of your page. The paid part is usually the letters inside it — and one well-known app states the limit in pages, which means you can do the arithmetic before you commit to a stack of documents.
Below, what two of the biggest scanners say in their own listings, and how to test it on one page before you scan a hundred.
The splitScan versus text
Level one — free, almost always
A clean, straightened, shareable PDF of your page. Adobe Scan’s description sells this as the no-cost baseline: “Adobe Scan is free to download and turns your mobile device into a powerful PDF and document scanner that helps you create, save, and organize your paper documents as digital files.” The technical work behind it is real: “Advanced scanning technology detects borders, sharpens content, and makes your scans editable and searchable.”
Level two — where the paywall usually sits
Selecting, copying, searching or exporting the actual words. Adobe states it plainly: “Turn images to text: Use the image-to-text feature to make words in your scans searchable and editable with OCR.”
The trap is that both levels feel like the same button. You aim the camera, you get a tidy PDF, and you only discover the difference when you try to copy a paragraph and nothing selects.
The number that answers the questionPages, not minutes
Adobe’s listing puts a price boundary on OCR in the only unit that matters to a real user — pages:
Adobe Scan, app description supplied by Adobe Inc.
A single contract, a receipt, a form you need to type into — this is enough.
An annotated reading list, a case file, a box of lecture notes. The vendor states the multiplier, not a time limit.
The page counts come from the listing, not from a stopwatch, and they describe capacity rather than a trial period. That distinction is the useful part: a scanned contract that will not let you search its text is not “expired”, it is over the allowance.
Another app, another kind of gate“Paid app only” written into the feature list
CamScanner’s listing describes the same capability in one sentence — and, unusually, marks another feature with its price condition in the text itself: “Extract Texts from Image OCR (optical character recognition) feature extracts texts from single page for further editing or sharing.” The next item in that list is flagged before you ever open the app: it is labelled “Paid app only” right in the feature list, ahead of “Share PDF/JPEG Files Easily share documents in PDF or JPEG format with others via social media, email attachment or sending the doc link.”
Two things are worth noticing in that pair. The extraction sentence limits itself to a single page, which is a different kind of rationing from Adobe’s page count. And the sharing line carries its own price tag in the store text, which is rare and useful: a vendor admitting, on the page where you decide to install, that a feature you assumed was free is not.
There is more than one app in the store with that name, from more than one publisher, including a paid variant whose listing text is quoted above. When you compare two scanner apps, compare the publisher line as well as the icon; otherwise you can be reading one product’s promises and paying another’s price. This site lists the app under the name CamScanner, and the sentences above belong to the record published by Shanghai Linguan Data Co., Ltd.
What the free tier usually does includeSo you can decide honestly
- Border detection, cropping, straightening and a shareable PDF — the “clear your desk” part.
- Sending that PDF by email or a link, in most apps, without paying.
- Basic cloud save to the app’s own storage, sometimes with a page or file cap.
- A searchable PDF only when the app has run OCR, which is the line many free tiers hold.
Before you payA two-minute test on one real page
- Scan a page you actually have, then try to select a single word. If selection works, the free tier has already done the job you were about to buy.
- Search the document for a word you know is in it. Searchability and selectable text are different features, and an app can give you one.
- Read the description for the word pages. Capacity stated in pages is the cheapest signal of where the paywall sits.
- Check what the paid tier unlocks elsewhere: Adobe notes that “Subscriptions work across Scan and Reader mobile apps and Acrobat on the web”, so one plan may cover more than the scanner — or quietly renew across all of it.
- If you need forms, look for the fill step. Adobe’s own text routes it outward: “Open your PDF scan in Acrobat Reader to comment, highlight, fill forms, and sign documents.”
Neither description states a price, a monthly allowance, what happens to text you already extracted if you stop paying, or whether OCR quality differs between tiers. None of that is guessed here. Prices and allowances change; the app’s own in-app purchase list, shown before you subscribe, is the current number. What we verified is that the free tier’s limits are stated in pages for both apps — that is the answer to the headline question, and anything finer needs your specific documents tested on the free tier first.
- All quoted sentences — the app descriptions Adobe (Adobe Inc.) and CamScanner (record published by Shanghai Linguan Data Co., Ltd.) supply for their own store listings, retrieved from the store’s public catalogue interface. Each was compared word for word against this page after normalising dashes and quotation marks, so the page counts, the “single page” wording and the “(Paid app only)” marker are reproduced exactly as published.
- One store image — supplied by Adobe and served by the store. The caption names what is in the frame, including the subscription asterisk, rather than treating a marketing screen as evidence of behaviour.
- Our own reading — the two-level split, the “capacity not expiry” point, the checklist and the warning about same-named apps. Not vendor claims; no OCR accuracy measurements were run, and we did not subscribe to anything for this article.
