Built by a materials scientist who runs Rietveld refinements every day — for the people who do the same.

Plotting XRD data is still stuck in 1998.

Every grad student rediscovers the same pain. Bragaf fixes it.

Origin costs a fortuneand half your lab shares one flaky license.
matplotlib eats your afternoonjust to get axes, fonts and offsets right.
FullProf / GSAS plots look datedgreat engines, figures you can't put in a paper.
Sharing means emailing screenshotsno interactivity, no version, endless back-and-forth.

Everything you need to go from raw data to a figure.

Runs in your browser. Your data stays on your machine unless you choose to save a project.

📈

Instant plotting

Drag & drop .xy, .dat, .txt, .xrdml, .raw, .ras — see it rendered in a second.

🖨️

Journal-ready export

Vector PDF/SVG or high-res PNG. Set fonts, colors and size to match your journal.

🗂️

Overlay & compare

Stack multiple patterns with offset and normalization to compare samples.

🏷️

Peak & hkl labels

Mark 2θ, d-spacing and Miller indices with a click. Clean, movable labels.

🧮

Peak fit & Rietveld

Pseudo-Voigt fitting, unit-cell refinement and full Rietveld (GSAS-II) in the browser.

Questions

Is it free?

Yes — plotting and figure export are free for students and individual researchers. A Pro tier (extra formats, cloud projects, collaboration) and lab/institution plans come later.

What happens to my data?

Your pattern is parsed and rendered in your browser. We don't upload or store it unless you explicitly save a project to the cloud.

Which file formats do you support?

Plain .xy / .dat / .txt, plus .xrdml, .raw and .ras. Tell us yours on the waitlist and we'll prioritize it.

Does it do Rietveld refinement and phase ID?

Yes — unit-cell refinement and full Rietveld (via GSAS-II) already run in the app, with guided phase ID on the way.
