Eight connected workspaces

One traceable path from profile to handoff

Braggsight keeps source bytes, row decisions, recipes, frozen results, reference correspondence, findings, and checksums together in a local casebook.

  1. 01

    Casebook

    Separate studies, specimen and instrument context, immutable revisions, findings, and reviewer disposition.

  2. 02

    Import Ledger

    CSV, TSV, XY, XYE, and text profiles with encoding, row outcomes, duplicate policy, step statistics, and SHA-256 provenance.

  3. 03

    Recipe Studio

    Named processing choices for smoothing, background, normalization, angular correction, wavelength, and peak thresholds.

  4. 04

    Pattern Canvas

    Touch-controlled observed, corrected, and normalized traces with visible baseline, range, and numerical evidence.

  5. 05

    Peak Lab

    Bounded fit windows, d-spacing, FWHM, area, fit quality, residual evidence, notes, and guarded width correction.

  6. 06

    Standards & References

    Multi-line calibration evidence, user-owned peak lists, and matched, missing, and unexplained correspondence.

  7. 07

    Series & Drift

    Compare frozen revisions and trend peak position, width, and area without hiding missing evidence.

  8. 08

    Evidence & Handoff

    Build a local PDF, numerical exports, recipes, ledgers, findings, manifest, and SHA-256 checksum list.

Immutable by design

Earlier evidence stays reviewable

Applying a recipe creates a new frozen revision instead of replacing an earlier result. The original imported bytes and the prior analysis remain available beside the current interpretation.

  • Original source data and import decisions remain preserved locally
  • Raw, corrected, and normalized channels stay visibly distinct
  • Unresolved corrections and missing matches remain explicit
  • Existing Braggsight 1.0 records migrate without deleting the original document
  • No account, subscription, ads, analytics, tracking, or required network

Responsible interpretation

Correspondence is evidence, not identification

Braggsight compares numerical one-dimensional powder-diffraction evidence. It does not identify an unknown phase, perform Rietveld refinement, control a diffractometer, certify an instrument or material, or replace laboratory procedures and expert review.

Private by design

Your laboratory workspace stays on your device

Profiles, context, recipes, revisions, reference lists, findings, and generated reports are handled locally. A file leaves only after you build an evidence package and choose a destination through Apple's share sheet.
