Context Pack Support

For help, email support@tryaiblock.com. Describe the file type and visible error without sending sensitive source documents.

Supported inputs

Selectable-text PDF, DOCX, Markdown, plain text, the readable current page, and the current main-frame selection.

Unsupported inputs

Scanned or image-only PDF, encrypted PDF or DOCX, and legacy .doc are not supported. OCR is not included. Embedded DOCX images are omitted, and complex layouts or merged tables may lose fidelity.

Current limits

• Markdown/plain text: valid UTF-8, 1.5 MB per file.
• PDF/DOCX: best under 10 MB; 20 MB hard limit per file.
• PDF: 30 pages per file and 60 PDF pages per pack.
• Mixed batch: 50 MB.
• DOCX expanded package: 80 MB.
• Pack: 10 retained sources and 500,000 UTF-16 code units.
• Page capture: before cloning, up to 40,000 main-frame elements, 100,000 total DOM nodes, and 5,000,000 raw UTF-16 code units across character data, attributes, and live form values; normalized Markdown is limited to 500,000 code units.
• Selection capture: before cloning, up to 10,000 selected, boundary, or restored-inline ancestor nodes and 500,000 raw UTF-16 code units across selected character data, cloned attributes, and live form values; normalized Markdown is also limited to 500,000 code units.

Token estimates

Per-source estimates cover normalized source content. The total covers the complete generated or edited Markdown. Both use packaged OpenAI o200k_base tokenization and may differ for other models.

Page capture

Chrome grants temporary access to the tab where the extension was invoked. Choose Capture page or Capture selection in the popup; Context Pack opens or focuses the current workspace and stages editable Markdown plus the captured URL for review before anything is added. The first-run guide appears inside that workspace and can be reopened through Help. Wait until the current capture, review, or conversion is finished before invoking it from another tab; the next capture then returns to the same open pack. Open current pack opens a new empty workspace when none is loaded or focuses the current workspace, without capturing. New pack clears the current in-memory session, with confirmation when it contains work. Closing or reloading always discards the editable session; copying or downloading keeps only the exported Markdown. Navigating away or closing the source tab may end access. A page or selection above the complexity or size limits is rejected without adding partial content.

Browser requirement

Chrome 140 or newer is required by the packaged PDF runtime.
