01 / ON-DEVICE AI

A little help, locally.

AI features require Apple Intelligence to be enabled and its on-device model ready. Availability depends on supported hardware, region, and language.

02 / BEFORE INSTALLING

A development preview.

This development preview is ad-hoc signed and has not been notarized by Apple. If macOS blocks opening, check System Settings → Privacy & Security for Open Anyway.

03 / YOUR FILES

Keep an editable original.

Basic Office compatibility. Advanced layouts and features may not be preserved. Keep original Office files and inspect exports. Save .psr to preserve Pulsar-specific features.

Release details, checksums, and sharing notes

Local writing, spreadsheet, and presentation checks do not verify factual accuracy. Review facts, figures, approvals, and exports before sharing. Pricing for future releases has not been announced.

Ordinary .psr files are readable JSON and include local AI activity and slide notes. Project Pack copies omit private AI activity, and the pack’s project data omits imported source excerpts and unapproved fact records. Authored document content is included.

Downloadable preview

Free preview for Apple silicon Macs running macOS 26 or later. No account or checkout is required to download. AI features need Apple Intelligence enabled and ready. This is a development preview with basic Office compatibility.

Core capabilities

Focused tools for the task.

Each capability is designed as part of the same product workflow, with context carried forward instead of rebuilt at every step.

Inputs and formulas

Work with a limited, supported formula language across multiple sheets. A Project Pack cost model calculates quantities and rates without asking AI to do the arithmetic.

Preview a scenario

Change an input in a what-if preview and inspect dependent formula results before applying it. Guarded Apply and Undo keep the decision explicit.

Review the model

Local workbook checks surface formula errors and issues that deserve attention. The checks do not verify your source figures or assumptions.

Charts and portable values

Save charts in .psr and export chart SVG. Export XLSX, active-sheet CSV/TSV values, or a tabular PDF of the workbook; charts are not embedded in XLSX or PDF.

How it works

From first signal
to a clear next move.

A deliberate sequence keeps the work understandable for the people doing it and reviewable for the people accountable for it.

Model

Enter values and supported formulas, or build a cost model from Project Pack estimate inputs.

Explore

Preview a changed input and compare the dependent results without editing the live model.

Decide

Inspect the scenario, apply it when appropriate, and use Undo if needed.

Export

Keep the full workbook as .psr and share XLSX, CSV, TSV, PDF, or a chart SVG.
