What it does

Writing a good prompt means juggling placeholders, formatting, variables, and rewrites — all in a tiny chat input box. PromptEditor gives you a proper side panel editor right in your browser. No tab-switching, no copy-pasting. Write, format, fill, share and send — all in one place.

PromptEditor is a free Chrome extension that adds a side panel editor to Claude, ChatGPT, Gemini, Perplexity & Copilot. Fill placeholders, set global variables, find & replace, save an unlimited prompt history, share prompts via link, and send directly to any AI chat. No account needed.

One click sends any AI response to your side panel. Fill placeholders, reformat, rewrite — then send to any AI chat, share via link, or copy as clean Markdown. Unlimited history. No tab switching. PromptEditor stays out of your way until you need it. Then it's just a click away. A button appears below every AI response on Claude, ChatGPT, Gemini, Perplexity, and Copilot. Click it and the side panel opens instantly with the text loaded in. Placeholders like [topic] and {variable} light up automatically. Click any one to replace it. Bold, italicise, add bullets — format visually, not in raw Markdown. Hit "Send to…" and your prompt lands directly in Claude, ChatGPT, Gemini, Perplexity, or…from prompteditor.ties.digital

    I was working on a project that involved indexing GitHub repos that used really long prompts. Iterating over each section and figuring out which parts of the prompt led to which parts of the output was a quite painful. As a frontend dev, I kept thinking it would be nice if I could just 'inspect element' on particular sections of the prompt. So I built this prompt debugger with visual mapping that shows exactly which parts generate which outputs. Now that context windows are getting huge, working with massive prompts should not be as difficult. Planning to open source this soon, but I'd love…

    Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  • Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
