OpenAI Turns ChatGPT Into a Daily Feed With Pulse

OpenAI just introduced ChatGPT Pulse for Pro users on mobile — and it flips the script. Instead of waiting for you to ask, ChatGPT now delivers a daily stream of updates tailored to your chats, preferences, and connected apps.

What Pulse brings:

  • Daily Briefings – Fresh topical cards each morning with reminders, ideas, and follow-ups.

  • Inbox + Calendar Integration – Drafts agendas, flags deadlines, even suggests restaurants for upcoming trips.

  • User Control – Thumbs up/down feedback + topic requests help refine what shows up.

  • Memory-Driven – Learns from your history to personalize future updates.

The upside? More productivity with less planning.

The downside? It’s another algorithm curating your life. Pulse is a step closer to assistants that don’t just answer questions — they decide which ones to bring you.

Meta Debuts Vibes: An AI Video Feed Nobody Asked For

Meta is pushing deeper into AI video with Vibes, a new feed inside the Meta AI app and on meta.ai. Think TikTok meets generative AI.

Here’s what Vibes does:

  • A personalized stream of AI-generated videos.

  • Tools to create new videos or remix ones already in the feed.

  • Direct sharing to Vibes, Instagram, Stories, and Reels.

  • Built-in Meta AI assistance + integration with AI glasses.

Meta says it’s about sparking creativity. But it also raises a big question: Will AI-driven video feeds like Vibes become the next wave of content creation — or just another algorithmic rabbit hole?

Today’s Prompt: Sales Email Creator (copy → paste → run)

Problem: Generic sales emails get ignored. You need concise, persuasive messages tailored to your audience and goals — fast.

Solution: Drop this prompt into ChatGPT, fill the placeholders, and get a ready-to-send, structured sales email with subject lines, opening, body (dependency-grammar style), close, and CTA.

Prompt:

ROLE: You are an expert copywriter and sales strategist.

OBJECTIVE: Create 3 variations of a persuasive sales email tailored to the info below. Each email must include: Subject Line, Opening, Body (use the dependency-grammar framework for clarity and flow), Closing, and Call-to-Action.

CONTEXT (fill these):
My target audience: [INSERT TARGET AUDIENCE]
My product/service: [INSERT PRODUCT/SERVICE]
My unique selling points: [INSERT UNIQUE SELLING POINTS]
My brand voice: [INSERT BRAND VOICE — e.g., "friendly, authoritative, concise"]
My desired call-to-action: [INSERT DESIRED CALL-TO-ACTION — e.g., "Book a 15-min demo"]

REQUIREMENTS:
- Provide 3 distinct email variations** (short, medium, long).  
- Each variation must have:
- Subject Line: (3 options: transactional, curiosity, benefit-driven)
- Opening: (1–2 lines that hook)
- Body (3–5 short paragraphs using dependency-grammar for clear, action-first sentences)
- Closing (1 sentence)
- Call-to-Action (clear, time-bound, and specific)
- Add a one-line personalization token suggestion (e.g., “Reference: [recent product launch]”) for each email.
- Keep length practical: Short (≤75 words), Medium (100–150 words), Long (200–250 words).
- Use numbers/metrics where possible and include one short social proof line if available.
- Tone must match [INSERT BRAND VOICE].
- Do a Gap Check first: list up to 5 missing inputs (if any) then stop — wait for answers before proceeding.

WORKFLOW:
1. Gap Check — list missing info (max 5 bullets).
2. Produce 3 email variations per requirements.
3. After emails, provide a 5-point send checklist (best send times, subject A/B test, follow-up timing).

FIRST ACTION: Start with the Gap Check (up to 5 bullet points). Wait for my answers, then generate the emails.
