Overall verdict

  • OCRStack appears to be a niche OCR (Optical Character Recognition) API/tool aimed at developers who need text extraction from images and documents, though it's a smaller player compared to major providers like Google Cloud Vision or AWS Textract, so due diligence on accuracy and reliability is recommended.

  • May provide competitive pricing compared to larger cloud providers for basic OCR tasks
  • Likely offers API access suitable for developers wanting to add OCR to their applications

Questions & Answers

As answered by people managing Gallera OCR and OCRStack.

Who are some of the biggest customers of your product?

Gallera OCR's answer

  • Not tracked: there are no accounts and no analytics, so we do not know who uses it

What makes your product unique?

Gallera OCR's answer

It copies tables as tables. Right-click a picture of a table, choose Copy as table, and paste into Excel or Google Sheets: every value lands in its own cell. Recognition runs on your device, so the image is never uploaded. When the text cannot be read, it says "No readable text found" instead of copying garbage. The same engine also works as a free online tool on the website, with nothing to install.

Why should a person choose your product over its competitors?

Gallera OCR's answer

Choose it if you care about tables and privacy. Most OCR tools give you one block of text; this one keeps rows and columns. Most online converters upload your file to a server; this one reads it in your browser, with no account and no analytics. It works by right-clicking any image, so there is no area to select.

Where it is weaker: it reads English and German only, and handwriting and photos taken at an angle are hit and miss. We keep an honest comparison with other OCR extensions, including where they do better: https://ocr.gallerastudio.com/best-ocr-chrome-extensions

How would you describe the primary audience of your product?

Gallera OCR's answer

People who regularly need text or numbers out of images and PDFs and would rather not upload them anywhere: analysts and office workers copying tables from screenshots and reports, bookkeepers and freelancers working with invoices and bank statements, students and researchers quoting from scanned pages. The extension is for Chrome on desktop; the online tool also works on phones.

What's the story behind your product?

Gallera OCR's answer

Gallera Studio is a one-person software studio with an AI crew: one human decides what gets built and reads every change, AI agents write the code, copy and tests. Image to Text OCR started from a small, repeated annoyance: copying a table out of a screenshot and getting one long line of text.

The first build had the same problem. Tesseract read table borders as letters, collapsed tables into one column and never admitted it could not read something. Line removal, confidence checks and scaling by letter height fixed it before release. To publish it, the studio unpublished its first extension: a new Chrome Web Store publisher gets two slots. The longer story: https://gallerastudio.com/log/tesseract-js-tables-and-honest-ocr

Which are the primary technologies used for building your product?

Gallera OCR's answer

  • Tesseract.js (WebAssembly) for recognition, with English and German models bundled
  • PDF.js for reading the text layer of PDFs
  • Our own table module: word boxes to rows and columns, grid-line removal, skew correction
  • Chrome extension on Manifest V3, plain JavaScript, no framework, no server
  • The website runs the same engine module in the browser, hosted on Cloudflare
