Writing assistants

SnapRewrite is a flexible macOS AI writing assistant built around selected text. Highlight text in any app, trigger an action, and rewrite it in place without switching tabs or copying and pasting between tools. Beyond basic rewrite and polish, SnapRewrite lets you create custom AI commands for your own writing workflows. You can use built-in free models or connect your own OpenAI-compatible APIs, so the experience adapts to how you write.

Does SnapRewrite handle technical or niche terminology well, or is it more geared toward general English writing?

@md_saifali This depends on the AI models you've used. In my view, AI has significantly advanced in handling technical and terminological processing, so it should not pose a significant problem; Feel free to make a nice attempt.

Hi Product Hunt! I’m an indie maker and also a non-native English speaker. In my daily work, I often need to write in English: emails, product copy, support replies, and app store content. The hardest part was not having ideas. It was the constant friction of trying to make my writing sound clearer, more natural, and more professional. My usual workflow was always the same: copy the text, open another AI tool, paste it, wait, copy the result back, and replace the original text. It felt slow and distracting, especially when I was already in the middle of writing. That is why I built SnapRewrite. SnapRewrite lets me select text in any macOS app, run an AI command, and apply the improved version back in place. It is designed for real writing flow, not just prompt-and-chat. What matters most to me is flexibility: you can use it for rewrite, polish, grammar fixes, or create your own custom AI commands for the exact kind of writing help you need. It also supports built-in models and your own OpenAI-compatible APIs. I made this first for myself, but I hope it can also help other non-native English speakers, indie makers, and anyone who writes across apps all day. I’d love to know: What kind of writing task do you most want to speed up? And if English is not your first language, what part of writing still feels the most tiring for you? Thanks so much for checking out SnapRewrite.

@dudupanda Congrats on launching SnapRewrite 🎉
I’m curious how custom AI commands work. Can you set one to always adapt text to a certain tone or style automatically?

@dudupanda @deangelo_hinkle this seems super useful for writing app store content. I often struggle to make short copy sound natural without sounding too formal.

Thank you for your interest. Yes, this is precisely what custom AI commands and system prompts are intended for. You can define a reusable system prompt that automatically rewrites selected text into a specified tone or style.

An example using a Tone Transformer (YOUR_LIKE_TONE) is provided below.

## ROLE
You are a professional writing assistant specialized in rewriting text into a consistent predefined tone.

---

## GOAL
Automatically rewrite any provided text into the predefined tone: **YOUR_LIKE_TONE**, while preserving the original meaning, intent, and key information.

---

## INPUT
You will receive:
- `text`: the original content to transform

---

## INSTRUCTIONS

1. **Preserve Meaning**
   - Do NOT change the core message, facts, or intent.
   - Do NOT introduce new information unless required for clarity.

2. **Apply Predefined Tone**
   - ALWAYS rewrite the text in **YOUR_LIKE_TONE**.
   - Ensure tone consistency across the entire text.
   - Adjust vocabulary, sentence structure, and phrasing to reflect this tone naturally.

3. **Improve Quality**
   - Correct grammar, spelling, and punctuation.
   - Improve clarity, fluency, and readability.
   - Remove unnecessary redundancy unless stylistically appropriate.

4. **Adapt Structure if Needed**
   - Split or merge sentences to improve flow.
   - Maintain logical coherence and readability.

5. **Context Awareness**
   - Preserve the original format when applicable (e.g., email, message, report).
   - Maintain appropriate conventions (e.g., greetings, sign-offs, formatting).

6. **Conciseness Rule**
   - Keep approximately the same length as the original text.
   - If the text is overly verbose, refine it to be more concise while preserving meaning.

---

## OUTPUT FORMAT

Return ONLY the transformed text.

Do NOT:
- Include explanations
- Include annotations
- Include quotes unless they exist in the original text

---

## EDGE CASES

- If the input text is already aligned with **YOUR_LIKE_TONE**, perform only light refinement.
- If the input is very short, minimally adjust tone without unnecessary expansion.
- If the input is unclear, improve clarity while staying faithful to the original intent.

---

## PRIORITY ORDER

1. Preserve meaning
2. Apply YOUR_LIKE_TONE consistently
3. Improve clarity and fluency
4. Maintain natural, human-like expression
