Digitizing paper responses shouldn't mean weeks of manual data entry.

Typing up hundreds of scanned forms by hand is slow and error-prone. Generic OCR tools don't know your survey's questions or options, so they guess instead of matching. Every new batch means starting over.

WITHOUT LENS

Staff manually retype every checkbox and handwritten answer from scanned forms. Mistakes creep in with every hour of data entry. Every question type, matrix grids, rank orders, open text, needs its own workaround. There's no way to reuse the work across batches of the same survey.

WITH LENS

Lens reads each scanned or marked response against your survey's own schema. Once a survey's layout is mapped, every batch of that survey reuses it. Low-confidence answers are flagged automatically instead of silently guessed. Fix one question or one response without redoing the rest.

From scanned PDF to structured data in four steps.

The layout only needs mapping once per survey. Every batch after that goes straight to extraction.

1

Bring your survey

Upload your Pirai AI base-format schema, or a raw questionnaire document and Lens derives one. This becomes the answer key every response is checked against.

2

Map the layout, once

Upload one blank or sample copy of the survey. Lens reads every page and proposes which questions live where. Review and confirm before processing real responses.

3

Scan and upload responses

Drop in scanned or marked PDFs in bulk. Lens reads checkboxes, ratings, and handwriting, verified against the schema, not guessed.

4

Review, reprocess, export

Low-confidence or blank answers are flagged for review. Edit any answer directly, reprocess a single question, or reprocess a whole response, then export to CSV or Excel.

Watch Lens digitize a real printed survey

Convert the survey, map the layout from a blank PDF, upload a filled response, and export the result, start to finish.

Every question type your survey actually uses.

Not just checkboxes. Lens reads the full range of question types a real survey uses, each matched against its own known answer key.

Single Answer

Multiple choice with one selection per respondent.

Multiple Answer

Checkbox questions where more than one option can be marked.

Dropdown

Single-selection questions presented as a dropdown in your platform.

Matrix / Grid

Statement-by-scale grids, matched against every row and column.

Open Text

Handwritten short answers and essay responses, transcribed verbatim.

Form Fields

Multi-field entries like version numbers or device details.

Rank Order

Items ranked by the respondent, read in the order marked.

Constant Sum

Points or percentages allocated across a fixed list of items.

Built to be trusted with real survey data.

Lens covers the full digitization workflow, from reading the layout once to flagging exactly what needs a second look.

Works With Any Survey Template

No fixed layout to design around. Lens reads the survey you already built, in the format you already print, and maps it to your own schema.

Handwritten Answer Extraction

Reads handwritten short answers and essay responses, not just checkboxes, transcribed verbatim against your survey's own answer key.

Multi-Language Support

Reads marks and handwriting in the language your respondents actually used. Not limited to English-language surveys.

Reprocess Any Single Question

Spot a wrong or blank answer? Select exactly that question and reprocess it, without redoing the rest of the response.

Edit Any Answer Yourself

Every extracted answer is directly editable in the review screen. You're never limited to AI reprocessing, a human always has the final say before export.

Checked Against Your Survey

Every answer is checked against your survey's own questions and options, so nothing gets invented or mismatched.

Accurate Even When Questions Look Alike

Lens reads every response against your survey's exact wording, so two similarly worded questions are never mixed up, even when an answer spans more than one page.

Confidence Flagging

Low-confidence and blank answers are surfaced automatically, so review time goes where it's actually needed.

Export to Excel or CSV

Export as values or labels, split multiple-answer questions into separate columns, headers matched to your platform's convention.

Simple, usage-based pricing.

Pay for what you process. No separate platform fee.

$9.99
per 1,000 pages processed

Every scanned or marked page counts toward your total, whatever question types or how many questions it contains.

Frequently asked questions

What is Pirai AI Lens?

Pirai AI Lens is Pirai AI's paper survey digitization tool. It reads scanned or marked paper survey response PDFs and extracts every answer, checkboxes, ratings, matrix grids, rank orders, and handwritten text, matched against your survey's own schema.

How does Lens read handwriting and marked checkboxes?

Lens uses AI vision models to look at each scanned page and report what's visible, checked against your survey's own known options and items rather than guessed freely. Answers Lens isn't confident about are flagged for human review instead of being silently recorded.

Do I need to rebuild my survey in a new platform?

No. Lens works from the same schema Pirai AI already derives for 19+ survey platforms, so you bring the survey you already built or already ran, and Lens digitizes the paper responses against it.

What happens to answers Lens isn't confident about?

Low-confidence and blank answers are flagged automatically in the review screen, so you can check exactly the answers that need a second look instead of reviewing every response from scratch.

Can I fix just one question instead of reprocessing a whole response?

Yes. Lens can reprocess a single flagged question in isolation, or reprocess a whole response, without disturbing anything else already extracted correctly.

Can I edit an extracted answer myself instead of reprocessing it?

Yes. Every extracted answer is directly editable in the review screen. You don't have to rely on AI reprocessing, a human always has the final say before anything is exported.

Is my scanned response data used to train AI models?

No. Response images are processed only to extract your survey data. Nothing you upload is used to train AI models. Learn more →

What question types does Lens support?

Single answer, multiple answer, dropdown, matrix, open text, form fields, rank order, and constant sum, eight question types in total.
