Everything in the toolbox, and what each part is for.

The full reference. Versioning is the foundation, Loop is the workbench, and one library feeds your terminal, browser, and agents.

Version control, for real

Every save is a version. Nothing is ever lost to an overwrite again.

ver
Git-style history

Every edit becomes a numbered version with a changelog. Semantic bumps (minor/major) when a change matters.

diff
Visual diff

Compare any two versions side by side, inline or unified. See exactly what changed between v2 and v3.

rlbk
One-click rollback

New version made things worse? Roll back instantly. Linear history keeps the story readable.

link
Version-pinned permalinks

Share /p/your-prompt?v=3 and it stays v3 forever. Cite the exact prompt that produced a result.

Loop Engineering: your iteration workbench

“Improve” buttons are one-shot and subjective. Loop is measurable iteration against your own agent.

var3
Pattern-based variantspro

Generate concise, structured, and step-by-step rewrites of a prompt in one pass, grounded in the Pattern Library rather than random mutation.

exec
Test with YOUR agentpro

ple loop --exec 'claude -p {}' runs every variant through your real agent command and shows the outputs side by side.

win
Winner becomes a version

Pick the best variant and it lands in history with a Loop(strategy) changelog: diffable, reversible, auditable.

tok
Token deltas per variant

See −32% tokens next to a variant before you commit to it. Same quality for less spend is a win Loop makes visible.

One library, every surface

Anthropic’s own docs say Skills don’t sync across surfaces. Your prompts should.

cli
CLIlive

npm i -g promptlike. ple show, copy, get --var give raw, agent-readable output. Pipe prompts straight into any tool.

web
Web applive

Edit, version, organize, share. Your prompt repository in the browser, with the full history UI.

mcp
MCP servernpx promptlike-mcp

Your library as agent tools: list, search, get, and fill_variables from Claude Code or any MCP client. Read-only by design, so an agent can never burn your tokens or mutate your library.

ext
Chrome extensionin review

Your library in a side panel next to ChatGPT, Claude, and Gemini. Fill {{vars}} and copy without switching tabs.

Better prompts while you write

The editor works like an engineering tool: structure, patterns, and cost are visible as you type.

tmpl
{{variables}}

Placeholders turn a prompt into a reusable template. Fill-and-copy on web and extension, --var flags in the CLI, fill_variables over MCP.

pat
Pattern Libraryfree

8 proven patterns (Persona, Few-shot, Chain-of-Thought, Output contract, Critic pass and more) as copy-ready templates.

cost
Live token cost

Token count and per-call cost as you write, priced across Claude, GPT-4o, and Gemini. Know what a prompt costs before you ship it.

ai
AI improvepro

Structured critique that rewrites role, context, and instruction sections, and asks clarifying questions when your intent is ambiguous.

Built for daily reuse

A library you stop visiting is a graveyard. These are the reasons you come back.

cmdk
⌘K everywhere

Jump to any prompt by name from anywhere in the app. Keyboard-first, like your editor.

rcnt
Recently + Most Used

Your working set surfaces itself. Usage counts include copies from the CLI and extension, not just the web.

org
Projects, tags, search

Repository-style organization: projects like repos, tags for cross-cutting themes, full-text search.

team
Team libraryteam

Share one library with up to 5 members, role-based access, and a pooled AI token budget with per-member audit.

Your data stays yours

Private by default, exportable always. No lock-in as a business model.

priv
Private by default

Publishing a project or prompt is an explicit, confirmed action, never a side effect.

expt
JSON export, always

Export your entire library on any plan, including Free. Import it back or take it elsewhere.

sec
Engineering-grade security

Row-level security on every table, two-layer authorization on every write, and audited sensitive flows.

Saving and organizing is free, forever.

Pro adds unlimited history and the Loop workbench for $19/mo.
