💬 Summary

I found myself constantly inputing similar prompts when using ChatGPT. I wanted a faster way to reuse and insert prompts without breaking my typing flow. And I also want a place to save & manage my frequently used prompts.

so I built PromptCard, a chrome extension to make prompt input faster and more comfortable. https://promptcard.online/

It works like this:

- In ChatGPT input box, you can enter #prompt_shortcut.

- When you hit send, the content from the selected prompt will be inserted to that place and sent to ChatGPT.

Example:

Let's say you want ChatGPT to help draft an email to your boss to request a day off. You might sent this:

"My son has fever and I need to stay home tomorrow to take care of him. Please help me write a short, professional email to my manager. Write in a clear and professional tone suitable for workplace communication. Keep it polite, concise, and respectful."

If you saved the 2nd part above under #email_to_manager, the input will become:

"My son has a high fever and I need to stay home tomorrow to take care of him. #email_to_manager."

Notice that the prompt is much shorter, and #email_to_manager can be reused everytime you want to write email to manager. The extension also comes a website for prompts sharing and managemnt.

I would love to hear all the feedback/suggestions. Thanks!

🗣️ Post 2: Show HN: Sharebuttons.ai – generate AI share buttons for ChatGPT, Claude etc.

💬 Summary

Hi HN,

I built https://sharebuttons.ai, a free tool that generates sharable links and embeddable buttons to help your content get cited in AI platforms like ChatGPT, Claude, Perplexity, and Grok.

The idea is simple:

Instead of traditional social media buttons, these buttons generate AI-optimized prompts that include your content. When clicked, they open the selected AI tool (e.g. ChatGPT or Claude) with a pre-filled query referencing your material. This makes it easier for visitors to bring your content into AI conversations - and more likely to get it cited in AI-generated answers.

You can choose which platforms to support, and the tool gives you clean, ready-to-use HTML for your site. No signup, no scripts, just links, buttons and markup you can embed. It works with any type of site — blogs, documentation pages, landing pages, etc.

Benefits:

- Increases the chance your content gets cited in AI responses

- Helps build your brand’s presence in AI-generated output

- Makes it easier for users to reference your content directly in tools like ChatGPT

Examples of links:

Grok (Summarize): https://ivbnssfgtjtfuskcqkfh.supabase.co/functions/v1/track-...

Some websites are already experimenting with this approach. Designmodo's blog https://designmodo.com/email-design/ now uses similar AI-friendly share buttons to improve visibility in AI-generated content.

I'm looking for feedback:

- Is this useful to you?

- Would you add something like this to your site?

- Any improvements or additional AI platforms you'd want supported?

Feedback and critique welcome.

Thanks!
