LATEST DEVELOPMENT / PREVIEW 3

Go further into the file.

Built beyond the downloadable Preview 2. These additions are being prepared for the next preview; they are not included in the downloads below.

EXECUTABLE STRUCTURE

ELF. PE. Mach-O.

Explore headers, sections, imports, symbols and supported relocation records. Universal Mach-O architecture filtering keeps slice and file coordinates distinct. Exact stored fields link directly to Hex.

DURABLE INVENTORIES

A page at a time.

Disk-backed inventories keep large symbol and import lists out of the interface’s working memory. Browse bounded pages, continue queries and restore the page and record you selected. The focused 12,500-symbol workflow passed in native Codex and ChatGPT.

SMALL + LARGE FILES

Follow the bytes to the end.

File-backed editing supports sources up to 16 GiB, with accurate navigation, saved per-file positions, background search, streamed comparison and disk-space checks. Document and provider-specific processing has its own supported scope.

Ask in your conversationOpen the relevant panelExpand your Retained workspaceFollow exact source bytes

Your workspace remembers.

Inline results focus on the task you asked about. Expansion brings that panel forward in your retained layout. Each file restores its own docks, active tabs, splits and selection.

Scan with visible coverage.

Development adapters stream whole-file YARA capture and exact entropy for larger inputs. Security Check reports progress, cancellation and explicit provider gaps, with source-bound Findings instead of an overall “safe” label.

One investigation, linked views.

Keep Hex and code visible while inspecting documents, certificates, findings and evidence. Review assistant explanations with citations, stage precise patches and save a verified copy.

NEW IN DEVELOPMENT / DEV.19

Recognize it. Preview it. Follow the source.

Format icons and explicit preview actions bring readable content into your dockable workspace. Open a preview beside Hex, or give it the full pane—your per-file layout stays yours.

Documents and data

Read Markdown headings, tables and code blocks. Browse CSV/TSV tables with row search, encoding and delimiter controls. Explore JSON, XML and YAML trees, then follow supported fields to their stored source bytes.

Images and messages

Preview supported WebP, GIF, TIFF, BMP, ICO and basic SVG alongside PNG and JPEG. Inspect EML and supported MSG headers, stored message content and attachment inventories. Previews stay passive: no remote images, active HTML or attachment execution.

Office and ZIP64

Inspect Word paragraphs and tables, Excel formulas and cached values, PowerPoint slide content and package image assets. Browse ZIP64 metadata, follow exact extended fields to Hex, and explicitly preview or export supported small members.

These are bounded inspection previews, not full Office rendering or recalculation. Office images are package assets, not reconstructed page or slide placement. Animated and multipage images use a supported static frame/page. The latest development source is ahead of the Preview 2 installer below.

INSIDE YOUR CONVERSATION

Ask. Open. Explore.

PryIDA is an interactive app panel inside Codex and ChatGPT, with a connected MCP backend.

01 / OPEN FROM A PROMPT

“Show this file in PryIDA.”

Ask your connected host to open a permitted file. Expand the visual result and work with the actual editor, not a screenshot.

02 / SHARE THE CONTEXT

Ask about the selection.

Give the assistant exact selected bytes, source identity and retained analysis. Follow evidence citations back to Hex, code and graphs.

03 / REVIEW THE CHANGE

Keep control of the edit.

Review proposed byte patches and instruction-aware previews. Apply deliberately, reanalyze with REA, undo or redo, and save a verified copy.

Codex uses the local plugin package. ChatGPT requires a separately reachable, connected backend, account availability and consent; the desktop installer does not create that connection or confer public app-directory approval. Connection guidance ↗

A TOUR OF PREVIEW 2

More than a hex view.

Eight real Preview 2 captures, before the PryIDA rename. Open any screenshot for a closer look.

8 views

01 / WORKSPACE

Arrange the investigation around you.

Dock, split, resize and collapse panels. Each file restores its own layout, active tools and byte selection.

  • Drag tabs or whole groups to any side.
  • Keep Hex, assembly, pseudocode and control flow visible together.
  • Auto row sizing, two-byte rainbow colors and a slim File Map make dense data easier to read.

02 / PDF

See the objects behind the document.

Explore a PDF object tree, pages, streams, attachments, layers and scripts beside the original bytes.

  • Verified object headers link directly to Hex.
  • Preview supported images and rendered pages; extract resources explicitly.
  • Logical and decoded coordinates remain distinct from encoded file offsets.

03 / ZIP

Open the container. Follow its contents.

Browse archive members with header and payload offsets, content identification, filename mismatch indicators and resource extraction.

  • Navigate folders and review filters.
  • Preview supported text, hex and PNG/JPEG resources.
  • Open decoded members as separate investigations with their source identity.

04 / DOCX

Look inside a Word document.

Inspect DOCX stories, tables, package relationships and embedded resources without launching Office.

  • Follow package parts back to their encoded bytes.
  • Inspect external references and supported image resources.
  • Document inspection is passive; macros and active content are not executed.

05 / XLSX

Read formulas without running them.

Browse worksheets, stored formulas, cached values and supported cell references in an Excel package.

  • Inspect hidden sheets, styles and supported date previews.
  • Distinguish stored formulas from their cached results.
  • Formula execution and full Office rendering are outside this inspector.

06 / CERTIFICATE

Make certificate structure readable.

Explore ASN.1 and PEM structures, certificate identity, validity dates, key metadata and supported extensions.

  • Follow source-backed fields into Hex.
  • Hash bytes and perform strict hex/Base64 transformations.
  • Certificate inspection does not establish chain trust or revocation status.

07 / ELF

Explore the executable before analysis.

Inspect ELF headers, segments, sections and linked records in a dedicated dockable explorer.

  • Select stored fields to reveal their file bytes.
  • Keep executable structure alongside Hex.
  • The next preview adds PE, Mach-O and durable paged inventories alongside ELF.

08 / SECURITY

Turn checks into linked evidence.

Run an explicit, cancellable Security Check and inspect coverage, archive contents and source-bound observations.

  • Combine supported identity, entropy and document/archive checks.
  • Use optional local YARA and antivirus providers where supported.
  • Findings, evidence relationships, saved queries and reviewed explanations keep conclusions close to their sources.

Screenshots use generated fixtures in the local macOS interface. They illustrate the shared interface; they are not Windows desktop-host screenshots.

POWER WHERE YOU NEED IT

Inspect first.
Analyze deeper.

Use the core editor without Ghidra. Add REA/Ghidra for fresh native-code analysis.

A precise editor

Hex/text search, comparison, bookmarks, declarative structures, reviewed patches, immutable originals and verified save-copy.

Connected reverse engineering

Functions, symbols, strings, xrefs, assembly, listing, pseudocode and control flow. Inspect function contracts, value dependencies, switches and instruction anatomy using retained provider evidence.

Evidence you can follow

Linked Findings, relationship queries, saved queries, reports and reviewed AI explanations with citations. Source and revision identity travel with each observation.

AVAILABLE NOW / PREVIEW 2 · LEGACY HEX EDIT NAME
