presentation-md vs Hallmark — deck craft vs anti-slop UI skill

Different jobs, same shelf

Hallmark (Nutlope/hallmark · usehallmark.com): design skill for greenfield pages, audits, redesigns, and DNA study from URL/screenshot. ~20 themes, 21 macrostructures, 57 slop-test gates, four verbs.
presentation-md: agent-native slide decks — typed Deck JSON, 75 themes, craft audit + judge, 14 MCP tools, Studio, editable PPTX.
You keep: anti-slop taste, skills.sh install habit, opinionated craft before emit
You gain (for decks): re-theme without rewrite, audit/repair loop, Office handoff, shareable editable Studio links

Prefer zero commitment? Open Studio with no install.

One-prompt → shareable artifact

Hallmark’s killer flow is brief → working HTML page. We close that gap for decks with the same shelf energy:

scaffold_deck(purpose, theme)
→ craft-floor Deck JSON
→ studio_share_url (?d= compressed token)
→ user opens editable Studio · agent continues with audit_deck / fill copy

npx @presentation-md/install claude-code
# then ask: scaffold a pitch deck and give me the Studio link

CLI parity: presentation-md-render --scaffold pitch -o deck.json prints a Studio share URL. Studio Land scaffold + Copy link match the same codec.

Side-by-side

Criterion	presentation-md	Hallmark
Primary artifact	✓ Slide decks (HTML + editable PPTX + Deck JSON)	Landing pages / UI (self-contained HTML+CSS)
Where it runs	Claude Code, Cursor, Copilot, Codex, Gemini CLI + MCP	Claude Code, Cursor, Codex (skill)
Authoring model	✓ Typed Deck JSON — re-theme, audit, diff, export	Opinionated freeform HTML/CSS from skill rules
Themes / variety	✓ 75 schema-validated theme packages + brand import	✓ ~20 named themes + custom OKLCH branch + 21 macrostructures
Anti-slop craft	✓ Anti-slop bans + craft audit + judge tiers + apply_safe_fixes + remorph_density	✓ 57 slop-test gates + pre-emit 6-axis critique
Verbs / workflow	scaffold/build · audit · remorph/retheme · share (+ brand/PPTX/MD study)	build · audit · redesign · study
One-prompt share	✓ `scaffold_deck` returns `studio_share_url` (`?d=`); Studio Copy link	✓ Emits a working page; host/share is project-local
MCP / typed tools	✓ 14 tools (render, export, audit, judge, scaffold, share, preview, import…)	✗ Skill references; live preview MCP is on their roadmap
Browser Studio	✓ Hosted editor — filmstrip, Present, craft panel, Generate, share	✗ Showcase site + examples (not an editor product)
PowerPoint	✓ Native editable PPTX export + import round-trip	✗ Not a deck/Office product
Install	`npx @presentation-md/install` · `npx skills add isatimur/presentation-md`	`npx skills add nutlope/hallmark`
License / price	✓ Free, MIT, no account	✓ Free, MIT

Where Hallmark is stronger

Best-in-class anti-slop page craft — structural variety (macrostructures), nav/footer archetypes, responsive gates, study-from-URL/screenshot DNA
Viral gallery energy and Together AI distribution mindshare for UI generation
Four crisp verbs with deep reference packs for greenfield sites, audits, and redesigns inside existing codebases

Where presentation-md is stronger

The right product when the ask is a deck — pitch, wrap, keynote, investor update — not a landing page
Schema-validated Deck JSON you can re-theme, remorph, audit, and round-trip through PPTX
75 published themes with structured gallery proofs + Studio pick-3 / My deck restyle
MCP craft loop: scaffold (with share URL) → audit/repair → judge → render/export
Hosted Studio with Present chrome and shareable ?d= editable links
Works across five coding agents with one installer — not only the Claude/Cursor/Codex skill shelf

Verdict

Use Hallmark when you need a page that refuses to look AI-generated. Use presentation-md when you need a deck that refuses the same — with schema, themes, MCP, Studio share, and PowerPoint you own. They share craft taste; they do not compete for the same artifact. No fake metrics: Hallmark leads page DNA; we lead agent-native deck shipping.

One command when the brief is a deck:

npx @presentation-md/install claude-code

Install for your agent → Try Studio first →
