Pick a period from the menu at the top right: Today, This week, This month or All time. The arrows step to the previous or next period, and Choose date… jumps to the day, week or month around a date. Under the title you'll see the dates covered and, when both periods have notes to compare, a line such as “Compared with the week before”.

The list starts with what changed, or the main themes when nothing stands out. Each theme shows its movement: New, More than before or Less than before, and a count like “3 → 9 notes”. Click a theme to see:

• From your notes: the excerpts behind the theme, each with its note and date. Click one to read the note inside Mindprint; open it in the editor from there.
• A small chart of notes per week (or day, or month) when there's enough history to draw one.

Below the themes, Worth a look shows at most two things to follow up, each with Open note or Ask. If a short period is empty, Mindprint offers Show this month.

Right-click a theme, or use the … menu next to its name, for:

• Rename: type a better name in the title field and press Return. “budget sheet” can become “Renovation budget”.
• Pin / Unpin: you can pin up to three themes. With three pinned, the menu offers Pin in place of instead.
• Merge with: combine two themes that are really one. Unmerge splits them again.
• Hide: drop a theme from the list. Hidden themes collect under Hidden themes, each with Restore.

These choices change how Mindprint labels themes. They don't change your notes.

Click Enhance with AI for a short AI interpretation of the themes, linked to the excerpts it relied on, and sometimes a list of Suggested theme changes (a better name, or two themes to merge). Nothing changes until you click Apply on a suggestion. The counts and excerpts still come from Mindprint's own analysis; the AI is told not to make claims about numbers or trends. Cancel stops it.

Header sends up to 30 themes with a few short excerpts and note titles each. It uses Apple Intelligence if you prefer on-device AI and your Mac has it, otherwise your AI provider from Settings → AI, and Apple Intelligence again if there's no provider.

Switch to Reflect to write a short note in your own words for the period you're looking at. A prompt at the top repeats what changed and the top themes. Fill in any of What changed, What mattered and Carry forward; your draft is kept as you type. Open Preview to see the note, then click Save to vault.

The note goes into Reviews/Mindprint/ in your vault, named after the period, for example 2026-10-18 week.md. Saving again for the same period makes a new numbered file instead of overwriting. Besides your answers, the note lists the period's themes with links to the notes behind them. It's marked mindprint: false so Mindprint doesn't count it as a source later.

Suggest a weekly reflection (on by default) shows “Last week had activity — write a short reflection?” in Themes when last week had notes. Click Start, or dismiss it for that week.

Press ⌥⌘I (View → Show Review Inspector). The Review and the Mindprint dock share one panel; the Themes and Review tabs at its top switch between them. Pick Today, Week or Month, or click the calendar button to open a different day, week or month.

At the top is a short retro for that period: how many thoughts you logged, your most active time of day, themes, open loops, and a line counting decisions, questions and citations. Header works it out on your Mac first. If you've set up an AI provider, Header may ask it to improve the retro while the Review is open, and the title changes from Local Retro to AI Retro. Below it are the captures themselves. Hover one for Edit, Save as Note (makes it a note of its own; the capture stays in the log) and delete. Deleting asks first, and can't be undone from Header. Triage itself is covered in Capturing ideas.

The Monthly Retro summarises the captures you made this month: themes, actionable loops, a mood and energy pulse, decisions made and unresolved questions, each with the captures it came from. Header writes it on your Mac, and only when you ask for it (next paragraph); opening Review on its own sends nothing. If you've set up an AI provider and have opened Review in this session, the command offers to send the local retro to that provider to improve it, after the usual send preview, and labels the result Monthly AI Retro; otherwise it's the Monthly Local Retro. If you cancel or the provider fails, the local version is kept.

To make one, choose File → Generate Monthly Local Retro (or Generate Monthly AI Retro), ⇧⌘R, or click Save Retro on the Month tab of the Review inspector. The retro is written into the month's capture log, the note named like 2026-10 Header.md at the top of your vault, and the Review opens on the month so you can read it.

To have it written for you, tick Write a Monthly Retro at month end on the Month tab. On the last day of the month, Header writes the local retro the first time it gets the chance (when you open the vault or capture something, for example).

With Flashback on, Header looks through your earlier captures while you type a new one. Once you've written a sentence or so, it may show Possible related note in … with the date, the words that matched, and a preview. Click See here to jump to it. Matches can be noisy, which is why it's in Labs and off by default.

A Share Pack is a folder of files built from your current Mindprint: its themes, connections and excerpts, as a briefing someone else can read. It isn't a backup and doesn't copy your notes, though theme names, excerpts and counts can still reveal private things, so read it before you send it.

A Share Pack needs a Mindprint from this session first. Open Mindprint (⌥⌘M) or run View → Ingest Vault (⇧⌘I); until then the Share Pack card and menu item stay greyed out. Then click Share Pack on the Explore page (under Protect & Share), or choose File → Export Knowledge Map… (⌥⇧⌘E). The Create Share Pack sheet walks through four steps:

1. Purpose and audience: Review, Presentation or Handoff; and Private review, Trusted team or Public sharing.
2. Snapshot contents: the number of themes and connections and when it was made. Optionally tick Include writing analysis and vault-level prose metrics.
3. Outputs: any of Markdown Brief, PDF Briefing, PowerPoint Briefing, PNG Briefing and SVG Vector. A JSON manifest with each file's size and SHA-256 checksum is always added and checked after writing.
4. Destination: click Choose Folder…. Folders inside your vault aren't allowed. Header makes a new timestamped folder there and never overwrites an earlier pack.

A Preflight list flags anything to check. For Public sharing you also tick I reviewed this derived snapshot for public sharing. Then click Create Verified Share Pack.

Ingest Vault (⇧⌘I) opens the Mindprint dock and reads the vault again, and also analyses the writing across your Markdown files on your Mac. The status line reports how many files it analysed. Header doesn't do this on its own at launch, so run it when you want Mindprint and a Share Pack's writing metrics to reflect the latest notes.

Refresh Files (⌥⌘L) reloads the list of files and folders in the sidebar from disk. Use it if you added or moved files in Finder and they haven't shown up yet.
