How It Works

logdog.ai extracts tables from drill logs and core samples at scale
converting decades of legacy files to structured data in seconds

Upload

Drop your PDFs—any format, any age, even multi-hole documents. No preprocessing required.

  • Scanned legacy logs
  • Handwritten forms
  • Multiple holes per file
AI Processes

Our AI understands geological document structure—not just OCR.

  • Pages automatically classified
  • Tables merged across pages
  • Lithology descriptions enriched
Download

Get a structured database organized by drill hole with standardized categories.

  • Collar, Survey, Lithology, Assays
  • Excel, CSV, or JSON format
  • Source traceability included

Automatic Page Classification

Every page is automatically classified before extraction. The system recognizes what kind of page it's looking at and applies the right extraction strategy.

  • Cover PagesProject metadata, hole IDs
  • Collar HeadersLocation, azimuth, dip, depth
  • Log PagesLithology depth intervals
  • Assay TablesLab results, element values

Assay Table

Multi-Page Table Merging

Drill logs routinely span many pages. A single lithology or assay table might run across pages 3–8, and a single document may contain multiple holes. LogDog automatically detects and stitches tables into continuous datasets, grouped by hole.

  • Automatic DetectionMatching columns and depth continuity across pages, per hole
  • Seamless StitchingLithology and assay tables merged into one continuous dataset per hole
  • Source ProvenanceTrack which rows came from which page

Lithology Enrichment

The AI reads the geologist's original descriptive text and extracts structured fields directly from it. Nothing is inferred or hallucinated—every enriched value traces back to what the geologist wrote.

Enriched Fields

  • Rock TypeStandardized lithology
  • AlterationType + intensity
  • MineralizationMineral + percentage
"Med grained granodiorite, moderate silicification, 2% disseminated pyrite, minor chalcopyrite"
Rock TypeGranodiorite
AlterationSilicic (moderate)
MineralizationPy 2% (dissem), Cpy (minor)
"Dk grey fine gr diorite, wk-mod chlorite-epidote alt, tr pyrite on fractures"
Rock TypeDiorite
AlterationChlorite-epidote (weak-mod)
MineralizationPy trace (fracture)

Structured Drill Hole Database

The end result isn't a pile of raw tables—it's a structured drill hole database organized by hole with standardized categories.

  • Multiple Export FormatsExcel, CSV, or JSON output
  • Industry Software ReadyConsolidated drillhole database structure for Leapfrog, Micromine, Surpac, Datamine, and similar software
  • Results ManagementBrowse by file or by hole, with controls for exporting specific holes, categories, or all results
  • Source TraceabilityEvery extracted value links back to the original source page image

Frequently Asked Questions

Who is LogDog.ai for?

LogDog.ai is built for anyone working with drill log data — from independent consultants and junior explorers to major mining companies. We have plans scaled for every need.

What file formats are supported?

LogDog.ai currently supports PDF files. Each page of your PDF counts as one processing credit.

How accurate is the extraction?

Our AI extraction is highly accurate for most drill log formats. Results may occasionally need minor corrections, particularly with complex or unusual layouts. We recommend reviewing your extracted data before use. If you're not satisfied with the results, contact us and we'll re-process your document at no additional cost.

What export formats are available?

You can export your extracted data as Excel workbooks, CSV files, or JSON. We also offer a consolidated export that follows the industry-standard drillhole database structure used by Leapfrog, Micromine, Surpac, Datamine, and similar software.

Is my data secure?

Uploaded files are automatically deleted within 7 days (30 days for paid accounts). Your documents are not reviewed by staff and are never sold or shared. All connections use HTTPS encryption. Documents are transmitted to third-party AI providers (OpenAI, Anthropic, Google) solely for extraction processing. See our Privacy Policy and Terms of Service for full details.

Do unused credits roll over?

All credits expire 12 months from the date of purchase.

How do I purchase credits?

Contact us through the form below and we'll set you up with an access code.

What is the Enterprise solution?

Our Enterprise tier is designed for large-volume operations and back-end pipeline integrations. Contact us to discuss custom pricing and dedicated support.

Can you handle custom integrations?

Yes. We can build custom integrations for any workflow, data format, or specialized log file type. Contact us to discuss your requirements.

Do you have a referral program?

Yes, we offer an affiliate program. Contact us for details.
