Wild capture, not clean scans
Thermal receipts, kirana tags and shop boards shot on phones.
You gate every pair

Why India
What Breaks OCR on Indian Text in the Wild
Latin-only, studio-scan training sets fail on Indic shop text and thermal receipts. Collect the pairs that match production photos.
Two scripts on one board
Hindi + English, Tamil + English, Bengali + Latin — the line your model must read is often mixed, not a textbook sample.
Thermal and handwritten prices
Faded kirana receipts and chalk or pen tags break models trained on clean PDFs and Western invoices.
Phone glare and harsh sun
Glass boards, noon light, shade under awnings. Collect the capture conditions users actually submit.
Native typists as labels
Contributors type what they see — conjuncts, ₹, abbreviations — so ground truth matches the photo.
Scripts
Name the Script in the Brief
India is the country filter. The script you need belongs in the instructions — then reject pairs that use the wrong one.

Sources
Where the Text Lives in India
Pick the surface your model fails on. Contributors shoot that surface on a phone — or fill your blank templates with fictional data.
Shop receipts
Thermal kirana and café slips — faded, folded, half cut off.
Invoices and bills
Local layouts, GST-style lines and mixed-language headers.
Menus
Printed or laminated cards; Indic + English on the same page.
Price tags
Handwritten ₹ amounts and shelf stickers under plastic.
Product labels
Packaging text, ingredients and brand names on real SKUs.
Shop and street signs
Painted boards, neon and printed notices in mixed scripts.
Handwritten notes
Lists and ledgers — useful when print OCR is not enough.
Printed forms
Filled checklists and applications; cover personal fields.
Template forms
Your blanks, filled with fictional data — safest for PII.
Privacy
Documents Leak Data — Design the Brief for That
OCR collection is high-risk for personal data. The safe default is fictional templates; real receipts need cover-up rules and hard rejects.
Purpose before accept
State that people photograph text for OCR training. Contributors see it before they start.
No IDs. No bank docs.
Ban Aadhaar, PAN, passports and statements in the brief. Prefer your blank templates with fictional fields.
Cover or blur PII on real items
Names, phones and card numbers get covered before the shot. Reject leaks in review. You own DPDP compliance for anything that can identify a person.
One Brief
Same Brief, Different Scripts
One English brief. Contributors in different cities return the same task type — with local script on the photo and in the transcription.
Your brief
Photograph the nearest shop sign or price board. Type every character exactly — including ₹ and mixed English lines. No guessing faded text.

- 01
Write one brief: surface to shoot, script to type, exact-character rules.
- 02
Set country to India; name city or script if you need a narrower mix.
- 03
Reject pairs where the typed line does not match the photo.
How It Works
A Pair Is Not Optional
OCR training needs image and ground-truth text locked together. That is the unit you pay for and the unit you review.
- 01
Define the pair
Image collection, country India, surface to shoot, script to type. Require line-by-line typing that keeps ₹, digits and symbols exact.
- 02
Capture and type together
One submission = photo + transcription. Native readers type Indic text; you do not get image-only dumps.
- 03
Gate on character match
Approve only when typed text matches the photo. For stricter QC, run a second task that checks pairs.

Bought Packs vs Paired Collection
OCR buyers choose between opaque labeled dumps and controlled photo–text pairs. RapidWorkers is the second path: you own the script rules and the review gate.

Pay for Pairs, Not Guesswork
A sign photo with three typed lines costs less than a multi-line receipt. Rate follows typing effort. The 15% platform fee is in the estimate.

FAQ
Frequently Asked Questions
What do I actually receive per submission?
A phone photo of the text plus a typed transcription in the same submission. You review the pair character by character before payout.
Which Indic scripts can I ask for?
Devanagari, Bengali, Tamil, Telugu, Gujarati, Kannada, Malayalam, Odia, Gurmukhi, Urdu, plus Latin for Indian English. Name the script in the brief; coverage depends on who takes the task.
Can I mix Hindi and English on the same sign?
Yes. Ask contributors to type mixed lines exactly as printed. That is a common failure mode for OCR in India.
How do I avoid collecting personal data?
Ban IDs and bank documents. Prefer blank templates filled with fictional data. On real receipts, require covered names and card numbers — and reject leaks.
City or script targeting?
Country is India. Put city, state or script in the instructions and reject mismatches. Pilot first for less common scripts.
How do I raise transcription accuracy?
Reject imperfect pairs yourself, then optionally launch a second task where other workers compare photo and text.
What does it cost?
You set pay from $0.10 plus 15% fee. Full receipt typing costs more than a short sign. Campaigns start from $0.30.
Can you run script coverage for us?
Yes. We plan the script mix, recruit, QC pairs and deliver in your format.
