How to Use Saved AI Prompts Across Gmail, LinkedIn, Reddit and Notion

Saved AI prompts become much more useful when they work across the websites where you already write, read, research, and reply.

That includes Gmail, LinkedIn, Reddit, Notion, and any other browser-based tool where text is the main work surface.

The point is not to create a different AI workflow for every app. The point is to create reusable prompt actions that follow the task. Summarise, rewrite, explain, extract, shorten, make professional, and draft a reply are useful in many places because the underlying work repeats.

Use one prompt menu across your browser. Extension OS lets you save prompts and run them on selected text across the web: Install Extension OS.

This guide shows practical examples of saved AI prompts across Gmail, LinkedIn, Reddit, and Notion, plus a simple way to build a prompt menu that does not become cluttered.

Why Saved Prompts Work Across Apps

Most browser-based apps are different wrappers around text work.

Gmail is email text. LinkedIn is professional profile, post, and message text. Reddit is discussion text. Notion is note, document, and planning text.

The interfaces differ, but many tasks are the same:

• Make this clearer.
• Summarise this.
• Turn this into bullets.
• Make this sound more professional.
• Extract the action items.
• Explain this in plain English.
• Draft a thoughtful reply.
• Shorten this without losing the meaning.

When you save prompts by task instead of by app, you can reuse the same prompt across many places.

The Core Prompt Menu

Start with a small menu that covers the common jobs.

Prompt name	Saved instruction
Summarise	"Summarise the selected text in three bullets and end with the main takeaway."
Rewrite	"Rewrite the selected text to be clearer and more concise. Preserve the facts."
Fix grammar	"Correct grammar, spelling, and punctuation without changing the meaning."
Professional tone	"Rewrite the selected text in a professional tone that still sounds human."
Friendly tone	"Rewrite the selected text to be warmer and easier to read without adding new claims."
Extract actions	"Extract action items, owners, deadlines, and open questions from the selected text."
Explain	"Explain the selected text in plain English and define important terms."
Draft reply	"Draft a concise, helpful reply to the selected text. Acknowledge the main point and ask for missing details if needed."

This menu is broad enough to work across Gmail, LinkedIn, Reddit, and Notion, but still small enough to scan quickly.

Gmail: Saved Prompts for Email Work

Email is full of repeated micro-tasks. You write a rough reply, then need it shorter, warmer, clearer, or more direct.

Prompt: Rewrite a Rough Reply

Use this when the draft says the right thing but needs polish.

Rewrite the selected email draft to be clearer, warmer, and more concise. Preserve the facts, avoid sounding stiff, and do not add new commitments.

Good for:

• Customer replies.
• Internal updates.
• Follow-ups.
• Scheduling messages.
• Difficult but polite responses.

Prompt: Summarise a Long Thread

Use this when an email chain has become hard to track.

Summarise the selected email thread. List decisions, blockers, action items, owners, deadlines, and unanswered questions.

This prompt is useful because email threads often mix history, opinions, and next steps. The saved instruction tells the AI what structure to extract.

Prompt: Make It Shorter Without Sounding Cold

Use this when a message is too long but tone still matters.

Shorten the selected email by about 40 percent. Keep it polite, specific, and human. Preserve all important details.

LinkedIn: Saved Prompts for Professional Writing

LinkedIn has several text tasks: posts, comments, profile sections, outreach messages, and job-related research.

Prompt: Improve a LinkedIn Post

Rewrite the selected LinkedIn post to be clearer and more specific. Keep the author's voice, remove generic AI phrasing, and make the first two lines stronger.

Use this when the post has the right idea but sounds too vague or flat.

Prompt: Draft a Thoughtful Comment

Draft a concise LinkedIn comment responding to the selected post. Add one useful point, avoid hype, and keep the tone professional.

This works best when you select the post or the key paragraph you want to respond to.

Prompt: Analyse a Job Post

Extract responsibilities, required skills, nice-to-have skills, red flags, and questions to ask before applying from the selected job description.

The selected job description becomes the input, and the output becomes a quick decision note.

Reddit: Saved Prompts for Threads and Replies

Reddit and forum threads can be noisy. Saved prompts help you extract the useful parts before replying.

Prompt: Summarise a Thread

Summarise the selected thread. List the main arguments, points of agreement, disagreements, examples, and unresolved questions.

Use this when the conversation is long and you need the shape of the discussion.

Prompt: Draft a Helpful Reply

Draft a helpful Reddit reply to the selected text. Be specific, avoid sounding corporate, acknowledge uncertainty, and do not overclaim.

This prompt matters because Reddit replies need a different tone from workplace email.

Prompt: Extract the Strongest Arguments

Extract the strongest arguments from the selected comments. Separate evidence, opinion, assumptions, and questions.

This is useful for research, community management, and understanding a debate before entering it.

Notion: Saved Prompts for Notes and Planning

Notion is often a mix of notes, drafts, checklists, project plans, and meeting summaries. Saved prompts help clean up rough material.

Prompt: Turn Notes Into Action Items

Turn the selected notes into action items. Include owner, deadline, context, and priority only when stated. Add a short open-questions section.

Use this after meetings, research sessions, planning notes, or messy brainstorms.

Prompt: Clean Up a Draft

Rewrite the selected Notion draft to be clearer and easier to scan. Use short paragraphs and bullets where helpful. Preserve the author's meaning.

Prompt: Create a Summary at the Top

Create a short executive summary for the selected notes. Include the main point, decisions, risks, and next steps.

This is useful when a page grows over time and needs a scannable entry point.

How to Adapt One Prompt Across Apps

You do not always need a new prompt. Often, you need one extra constraint.

Base task	Gmail constraint	LinkedIn constraint	Reddit constraint	Notion constraint
Rewrite	Polite and concise	Professional but not generic	Casual and specific	Clear and structured
Summarise	Decisions and next steps	Key point and implication	Arguments and evidence	Notes and actions
Reply	Acknowledge and ask	Add one useful point	Avoid corporate tone	Capture decision
Extract	Owners and deadlines	Skills and requirements	Claims and assumptions	Tasks and open questions

This is the easiest way to keep the menu small. Save broad prompts first, then add app-specific variants only when the difference matters.

How Extension OS Helps

Extension OS is designed to make saved prompts available where the text already lives.

You select text in the browser, choose a prompt, and review the result. The workflow stays consistent across different websites because the prompt menu lives at the browser layer.

Saved Prompts Follow the Task

If "rewrite this professionally" is useful in Gmail, it is probably also useful in a LinkedIn message, a Notion draft, or a form field.

The prompt should follow the task, not the app.

Selected Text Keeps the Input Clear

Selecting text gives the AI a clear boundary. You choose the paragraph, thread, message, draft, or note that needs work.

That makes the output easier to review and less likely to drift.

The Browser Keeps Context Visible

The original app remains open. That helps you check whether the output fits the conversation, audience, and page context.

Build one reusable prompt menu. Save the actions you repeat across Gmail, LinkedIn, Reddit, Notion, and the rest of your browser: Install Extension OS.

Common Mistakes

Creating One Prompt Per Website Too Early

Start with task prompts. Add app-specific prompts only after you see a repeated need.

Ignoring Tone Differences

The same answer should not sound identical in Gmail, LinkedIn, Reddit, and Notion.

Add tone constraints where they matter.

Selecting Too Much Text

Select the smallest useful section. If the AI needs more context, expand the selection next time.

Sending Sensitive Text Without Thinking

Before running a prompt, check whether the selected text includes private, customer, confidential, or regulated information. Use approved tools and providers for sensitive work.

FAQ

For Everyday Users

Q: Do I need different saved prompts for Gmail, LinkedIn, Reddit, and Notion?
A: Not at first. Start with task-based prompts such as summarise, rewrite, explain, fix grammar, and draft reply. Add app-specific prompts only when the tone or output structure needs to change.

Q: What is the most useful first prompt?
A: "Rewrite the selected text to be clearer and more concise. Preserve the facts and keep the tone natural." It works across many writing surfaces.

Q: Can saved prompts make writing sound generic?
A: They can if the prompts are vague. Add constraints such as preserve the author's voice, do not add claims, avoid hype, and keep examples specific.

For Teams

Q: Can teams share prompts across different tools?
A: Yes. Teams can share task-based prompts for replies, summaries, extraction, and tone control while allowing role-specific variations.

Q: Should teams standardise tone prompts?
A: Yes, especially for customer support, sales, recruiting, and public replies. Shared tone prompts help consistency, but people should still review every output.

Q: What data rules should teams set?
A: Define which providers are approved, what text should never be sent, how outputs should be reviewed, and when local or BYOK workflows are required.
