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.

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.

A useful starting point

Adapt proposal, decision memo, and operating procedure templates to your project rather than starting with an empty page.

Requirements beside the draft

Edit the required-section checklist and use the heading outline to move through the document.

Loose ends in view

Local checks flag placeholders, missing or thin sections, and long sentences. Select an issue to jump to its text; these checks do not verify facts.

A calmer writing surface

Use rich text, tables, and focus mode. Review on-device AI suggestions before inserting them with a restore point.

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.

Start

Choose a template or build a starting draft from your shared project brief.

Shape

Write and format the content, then tailor the section checklist to your reader’s needs.

Review

Resolve draft details and check every factual claim and approval yourself.

Export

Keep a .psr original and create a DOCX, HTML, text, or PDF copy for sharing.

What better looks like

Designed around practical outcomes.

Make required sections visible during writing

Catch unfinished draft fields before sharing

Keep an editable original for the next revision
