Limitations and supported files

AI Hub usage is subject to these limits.

  • Instabase Drive storage includes up to one terabyte of storage for AI Hub projects and documents. Organizations can connect external storage if the Instabase Drive is insufficient.

  • Upload files of up to 50 MB or 800 pages each.

  • Upload up to 100 MB per upload batch.

  • Upload up to 100 files in a Converse conversation.

  • Upload up to 500 files in a Build project.

  • Process up to 1,000 files in an app run.

  • AI Hub is supported on the most recent two versions of Chrome, Edge, Firefox, Opera, and Safari.

Supported file types

These file types are supported for Converse and Build import.

.bat, .bashc, .c, .cc, .chtml, .cmake, .cmd, .cpp, .cs, .css, .csv, .cxx, .cy, .dockerfile, .doc, .docx, .eml, .gdoc, .go, .gsheet, .gslides, .h++, .hpp, .html, .java, .jpeg, .jpg, .js, .json, .mht, .mhtml, .mkfile, .msg, .pdf, .perl, .php, .plsql, .png, .pptx, .py, .pxi, .pyx, .r, .rd, .rs, .rtf, .ruby, .tif, .tiff, .ts, .txt, .xls, .xlsx, .xml, .yaml, .yml, .zsh

In commercial and enterprise Build projects with file splitting enabled, multipage files can include multiple documents. For best results in all other projects and conversations, use one file for each document.

If necessary, file rotation, skew, and warp are automatically corrected at upload.

Processed Build results can be exported in CSV or Excel format.

Processing details for specific file types

Certain file types have unique processing considerations.

  • Email files (.eml): Attachments are separated and treated as individual files.

  • Excel spreadsheets (.xlsx): Processed in their native format by default. This method offers better results for wide tables, but doesn’t support embedded objects, such as charts, or source highlighting in results. Alternatively, you can convert Excel spreadsheets to PDF by disabling Process spreadsheets natively in digitization settings for your conversation or project. PDF conversion adds minimal processing time to file digitization. Regardless of formatting, Excel spreadsheets are subject to these limitations:

    • Files must be less than 10 MB.

    • Advanced Excel features, such as macros and data validation, aren’t supported.
