Questions & Answers

As answered by people managing GImageReader and Colbot.

What makes your product unique?

Colbot's answer:

Colbot isn't just an OCR tool or a file converter — it reasons over the content with AI to derive fields that aren't spelled out in the source, then fits them to your existing spreadsheet.

  • Schema-aware, not template-locked — authorize a Google Sheet and Colbot reads your column headers to build a reusable parser. No per-document mapping rules to configure.
  • One pipeline, many inputs — drag in files (PDF, Word, Excel, images, CSV), capture web pages with the Chrome extension, or POST via API — everything flows through the same extract-and-append process.
  • Batch and parallel — drop a whole stack of mixed files at once; scanned PDFs and photos are read with OCR.
  • Human-in-the-loop, by choice — switch on an optional review step, with every extraction and write fully auditable.

Why should a person choose your product over its competitors?

Colbot's answer:

  • No per-layout templates — many extraction tools make you train a template for every document type. Colbot infers structure from your sheet's headers and adapts, so mixed and one-off documents just work.
  • It understands, not just transcribes — beyond copying visible text, the AI infers fields the source only implies, so you get spreadsheet-ready data instead of a raw dump.
  • Files and the web and API in one tool — no stitching together a scraper, an OCR service, and an automation app; Colbot captures from uploads, web pages, and API into Google Sheets through a single flow.
  • Built for teams, with a paper trail — roles, permissions, and an optional review step let people approve what the AI proposes, and every write is auditable.

How would you describe the primary audience of your product?

Colbot's answer:

Colbot is for anyone who repeatedly types data into a spreadsheet by hand and wants that to stop.

  • Ops, finance & admin teams turning invoices, receipts, and PDF forms into structured rows.
  • Analysts & researchers consolidating data from mixed files, scanned documents, and web pages.
  • Sales & e-commerce pulling product listings, prices, and leads off the web with the Chrome extension.
  • Teams that live in Google Sheets and want AI and people to share the work, with roles and review.

It fits individuals and small-to-midsize teams best — pay-as-you-go pricing lets you start without an enterprise commitment, while roles and permissions scale as the team grows.
