One library for your agent context.

The local-first context manager for the agent era. Your prompts, SKILL packages, and AGENTS.md files in one private library — owned by you, exported to every tool, never touching anyone's server.

Save your first prompt in about 30 seconds. No account required.

Prompt Organizer prompt library screen with reusable prompts and local storage controls

Prompts, skills, agent context, vault export. Everything starts and stays in this browser until you choose otherwise.

Observable privacy

Check the network story. Your prompt data stays put.

Marketing pages still load normal site assets. Your prompt library is different: saves, edits, tags, searches, references, and SKILL packages write to browser storage, not a Prompt Organizer prompt endpoint.

When you send text to ChatGPT, Claude, Gemini, or another destination, that handoff is the action you chose. Prompt Organizer does not receive a copy.

Thirty seconds: why prompts scattered across tabs and notes cost you, and what one local library you own looks like instead.

Built for the way agent work actually happens.

Skills, AGENTS.md files, and refined prompts are scattered across tools that don't talk to each other. These features pull that work into one library you own — and push it back out in the format each tool reads.

Universal agent-format export One library item, exported in the formats Claude Code, Cursor, Copilot, Gemini CLI, and Codex CLI read.

Skills authoring and linter Author SKILL.md packages against the open Agent Skills standard, with a linter that catches problems before an agent does.

Import from everywhere Bring prompts in from ChatGPT, Claude, Cursor, fabric, and CSV exports, then merge them into one library.

Prompt quality score A local scoring pass flags vague instructions, missing structure, and unused variables. No API call involved.

Version history with diffs Every revision is recoverable. Compare versions line by line and roll back an over-edited prompt.

Prompt Lab: test with your keys A fifth tool mode for side-by-side model comparison and AI prompt improvement. Local models via Ollama and LM Studio are free; cloud providers Pro. Keys stay encrypted in your browser.

Outcome tracking Log results per prompt — star ratings, model used, win/loss duels — so you know which version actually performs.

Context bundle composer Assemble prompts, references, and files into one send-ready bundle, budgeted against real model context windows.

Chrome companion, upgraded Capture and insert prompts on 15 AI sites — ChatGPT, Claude, Gemini, Perplexity, Copilot, Grok, Lovable, Bolt, Base44, and more — with in-chat /shortcuts and the public Prompt Library in the side panel.

Public Prompt Library Browse community prompts, skills, and agent packs at library.promptorganizer.app — and import them straight into your local workbench.

The prompt you refined six times is a context asset.

It carries your judgment, client vocabulary, evaluation criteria, and reusable structure. So do your SKILL packages and agent context files. Prompt Organizer keeps that work in one fast local library instead of scattering it across chat histories, proprietary tools, and shared docs.

Structure Prompts, variables, references, SKILL packages, and Agent Packs stay first-class.

Reuse Search, combine, and export in the format each tool reads, without rebuilding context per app.

Ownership Export the library as JSON for free, or package Pro bundles when it becomes team knowledge.

Read-only browsing. Your local library never syncs up without you.

One vault file. Yours to keep.

The vault is a plain JSON file you choose where to store. Prompt Organizer hash-verifies it, writes changes back, and keeps it readable enough to diff, sync, or archive without us.

Plain JSON, human-readable.No proprietary container. Open it in any text editor.
Checksum-verified.Each write hashes the payload. Corruption is detected on read; no silent data drift.
Diff-friendly.Track your library in Git. Review your own edits. Roll back over-edited prompts.
