Promptly.fyi VS DeveloperToolStack

Promptly.fyi's answer

Promptly combines three essential AI workflow tools in a single lightweight browser extension: a one-click prompt optimizer, a personal prompt library, and a conversation export tool. Unlike single-purpose prompt managers or marketplaces, Promptly works directly inside ChatGPT, Claude, Gemini, DeepSeek, and Copilot — no copy-pasting to a separate app required.

The optimizer (Ctrl+M) instantly rewrites any rough prompt into a well-structured, context-rich version. You can even highlight text anywhere on the web and optimize it as a prompt, not just inside chatbots. The prompt library lets you save, search, and pin your best prompts for one-click reuse across any AI platform. And the conversation exporter (Ctrl+E) lets you fork, export, or summarize long AI chats to beat context-window limits.

Unlike prompt marketplaces or single-purpose managers, Promptly combines a one-click optimizer, a personal prompt library, and conversation export in one lightweight extension — all working natively inside the AI tools you already use.

• All-in-one vs. single-purpose: Competitors like AIPRM or PromptBase focus on one thing (templates or a marketplace). Promptly does it all: optimize, save, reuse, and export.
• Works everywhere: Promptly runs inside ChatGPT, Claude, Gemini, DeepSeek, and Copilot simultaneously — switch models without losing your workflow.
• No app switching: The optimizer and library live in your browser sidebar. No copy-pasting prompts to a separate tool.
• Privacy-focused: Your prompts stay in your browser; nothing is sent to third-party servers.
• Proven and trusted: 30,000+ users, 4.5★ rating, and a "Featured" badge on the Chrome Web Store.
• Free to use: Core features are available at no cost on Chrome, Edge, and Firefox.

Promptly serves a broad spectrum of AI power users — anyone who regularly uses ChatGPT, Claude, Gemini, DeepSeek, or Copilot and wants to get more out of every interaction.

The primary audience includes:

• Knowledge workers & professionals who rely on AI for writing, research, analysis, and communication and want consistently better outputs without trial-and-error prompting.
• Developers & engineers who use AI for code generation, debugging, and architecture discussions, and benefit from keyboard-driven, structured prompts.
• Content creators & marketers who need reusable prompt templates for copywriting, SEO, social media, and campaign ideation.
• Researchers & students who run long AI conversations and need to export or summarize them before hitting context limits.
• Prompt enthusiasts & power users who want to build and maintain a personal library of their best prompts across multiple AI models.

In short: anyone who prompts AI daily and wants a faster, smarter workflow — without switching tools or paying for a premium plan.

Promptly.fyi's answer

Promptly was born out of a frustration that every frequent AI user knows: you type a quick, rough prompt and get a mediocre answer. Then you rewrite it. Then you rewrite it again. By the time you get a useful response, you’ve spent more time on the prompt than on the actual task.

The idea was simple — what if a single keystroke could do that rewriting for you, right inside the AI tool you’re already using? No new tab, no separate app, no copy-pasting.

From that insight, Promptly grew into a full prompt workspace: the one-click optimizer (Ctrl+M) that restructures any prompt in place, a personal prompt library to save and reuse your best templates (Ctrl+S), and a conversation exporter (Ctrl+E) so long research threads never get lost to context limits.

Today, Promptly is trusted by 30,000+ users across Chrome, Edge, and Firefox, rated 4.5★ on the Chrome Web Store, and carries a “Featured” badge — all while remaining free. The mission stays the same: help anyone who uses AI get sharper, faster results without becoming a prompt engineering expert.

Promptly is built as a cross-browser extension using standard web technologies, optimized for performance and compatibility across Chrome, Microsoft Edge, and Firefox.

• Browser Extension APIs — Built on the WebExtensions standard (Manifest V3 for Chrome/Edge, compatible with Firefox) for seamless integration into the browser without requiring native installs.
• JavaScript / TypeScript — The core extension logic, prompt optimization engine, and sidebar UI are written in modern JavaScript/TypeScript.
• HTML & CSS — The prompt library sidebar and UI components are built with clean, lightweight HTML and CSS for fast rendering.
• Chrome Storage API / browser.storage — User prompts and settings are stored locally in the browser using the browser’s built-in storage APIs, keeping data private and on-device.
• Content Scripts — Promptly injects lightweight content scripts into AI platform pages (ChatGPT, Claude, Gemini, DeepSeek, Copilot) to enable the in-page optimizer and keyboard shortcuts without modifying the underlying service.
• AI / LLM integration — The prompt optimizer leverages AI language model APIs to rewrite and enhance prompts in real time.
