Ever pause a 45-minute keynote just to figure out if the speaker said anything other than “AI, but bigger”? Same. The internet is full of great long-form video—and your time is aggressively not. So let’s fix it. Enter Comet, the new AI browser from Perplexity that promises to summarize videos, cut down the fluff, and help you share the good bits on social faster than you can find the skip-ad button.
Yes, it’s an AI browser. No, you don’t need a PhD in tabs to use it. Think of Comet like that friend who watches the entire YouTube tutorial and texts you the three steps that actually matter. It can analyze pages, surface summaries, and help you make content you can actually use on X/Twitter, LinkedIn, and beyond. And if you’re wondering whether this is another “neat demo, but I’ll forget it exists by Tuesday” situation—the short answer is: it’s getting real. Early hands-on reviews describe agentic shopping, summarization, and some practical assistant behavior—useful, if still evolving.
In this guide, I’ll show you how to use Comet to summarize videos and turn those summaries into scroll-stopping, shareable posts—without sacrificing your weekend, your sanity, or your dignity.
What This Is (And What It’s Not)
You: Do I need to import an entire content calendar into Comet?
Me: No. Breathe. Comet is a browser with a built-in AI assistant that can read, reason, and summarize across the web, including long-form content like videos. It sits on your desktop and acts like a research gremlin who’s actually helpful. Mashable called out its agentic features—shopping and summarization—and yup, that translates nicely to “help me digest this 90-minute panel so I can sound smart in a 90-second post”.
What it’s not: a full social media scheduling suite. Comet helps you create content from what you’re watching or reading, but posting and scheduling may still live in your platform-of-choice or via your usual social tools. That said, the workflow is fast—and very shippable.
Why Comet for Video Summaries Beats Your Manual Note-Taking
- It’s inside the browser: You don’t need extra extensions to get summaries as you browse sites and videos.
- It acts on context: Ask it to capture key points, timestamps, quotes, and takeaways, and it will stick to what’s actually on the page/video.
- It adapts to your tone: You can ask for bullet summaries for LinkedIn, spicy one-liners for X, or short hooks for Shorts/Reels.
How to Use Comet to Summarize Videos: The “Watch Less, Get More” Workflow
Let’s pretend you’re watching a 20-minute product demo and your boss Slacks: “Can you share highlights on LinkedIn in 10 minutes?” Cool. Here’s the speed-run.
Step 1: Open the Video in Comet
- Fire up Comet. Load the YouTube, Vimeo, or hosted video page.
- If there’s a transcript on the page or accessible closed captions, even better—Comet thrives on text context.
Step 2: Ask Comet the Right Questions
- Start with: “Summarize this video in 6 bullets with timestamp references and the top three takeaways for professionals.”
- Follow up: “Give me memorable quotes and any data points.”
- Go deeper: “Turn this into a LinkedIn post draft (max 2200 characters), an X thread (5–7 tweets), and a 60-second script for a vertical video.”
Step 3: Extract Timestamps, Not Just Ideas
- Ask Comet: “List the key moments with timestamps and a one-line highlight for each.”
- If the page offers chapters, tell Comet to align bullets with chapter markers.
Step 4: Build Platform-Ready Snippets
- LinkedIn: “Summarize for a business audience with a problem-solution structure and a clear CTA.”
- X/Twitter: “Give me 5 punchy tweets with a hook, a stat, and one contrarian take.”
- Shorts/Reels/TikTok: “Write a 60-second script, with a 5-second hook, 3 core points, and a 1-line takeaway.”
- YouTube Community posts: “Give me a 2–3 sentence recap with an open-ended question.”
Step 5: Refine for Tone
- Ask: “Make it sound authoritative but conversational. Avoid hype words.”
- Or: “Rewrite with light humor and a strong opener.”
Step 6: Copy, Paste, and Post
- Comet gives you a clean draft. Drop it into your platform. Attach a thumbnail or a clip using your native tools. Add hashtags sparingly.
Heads up: Based on early reviews, Comet’s most reliable magic is summarization and agent-like help inside browsing. Sharing and automation workflows may require your usual social tools for posting and scheduling. The official Comet page positions it as a personal assistant inside the browser itself—think research, automation, and organization, not a dedicated social publishing engine.
A Quick Reality Check
- Comet is new. That means expect improvements and changes. It’s designed to be a personal AI assistant inside the browser. For now, that’s where it shines.
- Real user takes? Some say it’s promising, useful for everyday tasks, but not “magic unicorn” yet. That’s OK. Unicorns are loud.
Your Summarize-to-Share Playbook (Copy This)
Use these reusable prompts with Comet while a video page is open:
- Core Summary
“Summarize this video in 6–8 bullets. Include timestamps, the main thesis, and one insight casual viewers would miss.”
- Social Atomization
“Create:
- LinkedIn post: problem-solution-outcome, with one stat and a CTA.
- X thread: 5–7 tweets, each 240 characters.
- 60-sec vertical script: hook (5s), 3 points (15s each), summary (10s).”
- Quote & Clip Finder
“Extract the 3 most quotable lines, a stat, and the most shareable 10–20 second moments with timestamps.”
- Voice & Tone Calibration
“Rewrite the outputs to be confident, approachable, and specific—no buzzword salad, no techno-jargon.”
- Compliance and Accuracy Pass
“Double-check facts, names, and numbers. Flag uncertain claims with sources or a note to verify.”
How to Turn a 30-Minute Video into Six High-Impact Posts (in 20 Minutes)
- Minute 0–3: Ask Comet for a timestamped summary.
- Minute 3–6: Ask for a LinkedIn draft (add your POV in brackets).
- Minute 6–9: Ask for an X thread (open with a counterintuitive stat or a question).
- Minute 9–12: Ask for a 60-second vertical script (record A-roll with your phone, add B-roll of the video or screenshots).
- Minute 12–15: Ask for a quick newsletter blurb (2–3 sentences and a link).
- Minute 15–18: Ask for a community post or short poll.
- Minute 18–20: Polish, fact-check, post. Eat a snack. You earned it.
Getting the Best Summaries: Pro Tips
- Feed it context: If the video page has an article or transcript, open it in the same tab. Ask Comet to consider transcript text.
- Be specific: “Business takeaways,” “developer impact,” “consumer-friendly recap”—the more specific you are, the better the summary.
- Use constraints: Set bullet limits, tone, and audience.
- Pull receipts: Ask for timestamps and quotes you can screen grab.
- Add your POV: AI can summarize; only you can provide the “why this matters.”
Reality vs. Expectation (With a Sprinkle of AI Honesty)
- Expect good structure and clear bullets.
- Expect to tweak tone and add your context.
- Don’t expect perfect automatic posting across platforms. Use Comet for the thinking and writing; use your native apps for posting and analytics.
When to Use Comet vs. Your Old Workflow
- Use Comet when you need speed, structure, and on-page context summarization—especially for conferences, product launches, and “I can’t watch all this” moments.
- Use your original setup (social schedulers, editing suites) for heavy-duty publishing, analytics, and collaboration.

The Wrap
Summarizing videos and turning them into shareable social content doesn’t have to feel like repotting a 6-foot fiddle-leaf fig—possible, but perilous.

It’s early, yes. But if your goal is to pull signals from noise and ship smarter, this is a solid upgrade for your browser—and your workflow.

FAQ
Q1:Can Comet automatically post my summaries to social platforms?
Comet focuses on summarizing and drafting inside the browser; posting and scheduling still live best in your native apps or social tools. Use Comet for the thinking, then copy-paste and publish for control and accuracy.

Open pages with transcripts or captions and ask for timestamped bullets, quotes, and key moments. Add constraints like audience, tone, and bullet limits for cleaner, more shareable results.

Comet structures the information for you—bullets, quotes, timestamps—so you can repurpose it quickly. It’s like having a diligent note-taker who doesn’t ask to borrow your Netflix password.
