The 90-Minute Content Sprint: Batch a Month of Posts with ChatGPT + Canva (+ A Simple Dashboard)
Batch a month of content in 90 minutes using a timeboxed sprint with ChatGPT for words, Canva for visuals, and a scheduler to publish while you live your life.
The 90-Minute Content Sprint (yes, it’s real)
Short answer: yes—you can batch a month of content in 90 minutes by timeboxing one focused session, using ChatGPT for rapid drafts, Canva Magic Studio for on-brand visuals, and a scheduler (like Buffer) to publish while you live your life. The magic is removing decision fatigue, templating the repeatable bits, and letting software do the heavy lifting.

What Is a 90-Minute Content Sprint? (and why it works)
A 90-minute sprint is a single, protected block where you plan, draft, design, and schedule a minimalist “Core 4” set of posts for the coming month. It works because of timeboxing (fixed time, fixed scope) and the friendly constraint that good enough beats never published. You’ll create four posts—one per week—using the same structure each month so your brain can coast on rails instead of reinventing the wheel.
The 3-Tool Stack (keep it simple)
1) ChatGPT for ideas, briefs, and first drafts
Use it to explode one topic into four angles, outlines, hooks, captions, and bloglets. Ask for your brand voice, then iterate once.
Copy-paste prompt:
“Act as my content editor. I’m writing for [audience]. Give me 4 post angles on [topic], each with a 120-character hook, a 150–200-word caption, and a skimmable bullet outline. Tone: smart, warm, zero fluff. Add 1 concrete example per post.”
2) Canva Magic Studio for fast, on-brand visuals
Start with a single template and your brand kit (colors + fonts). Generate one base design, then duplicate it for all four posts. Consistency > fancy. Export square (1080×1080) and story (1080×1920) versions.
3) Buffer (or your scheduler) to set-and-forget
Drop your captions and images into a queue and choose automatic publishing. For platforms that need final in-app stickers or music, use notification publishing so you can add the flourish without losing your schedule.
The 90-Minute Sprint: Minute-by-Minute Plan
Prep (before the timer):
Open your Content Dashboard (or a simple Google Sheet). Add a tab called Core 4. Paste your brand colors and save these four monthly buckets: Teach • Story • Proof • Offer.
Minutes 0–10: Timebox + topics
Set a 90-minute timer. Phone on Do Not Disturb.
Pick one theme for the month (e.g., “Getting consistent with content”).
Jot four working headlines—one per Core-4 bucket.
Minutes 10–35: Draft with ChatGPT (4 × ~6 minutes)
Paste the prompt.
Ask for a punchy first line and a single example.
Trim filler. Save each hook + caption to your sheet.
Minutes 35–70: Design in Canva (4 × ~8 minutes)
Open one Magic Design template; apply brand kit.
Duplicate the slide for each post; swap the headline and one accent color.
Export lightweight images (aim ≤150KB for web).
Minutes 70–90: Schedule everywhere
Create a post per week in Buffer.
Add the square image + caption for feed; add the story version to Stories.
Choose automatic publishing, or notification if you’ll add in-app touches.
The “Core 4” Template Pack (use it every month)
Teach — “3 Easy Ways to [Solve Pain Point] This Week”
Story — “The Week I Finally Fixed [Annoying Problem]”
Proof — “What Happened When I Tried [Tool/Method] for 30 Days”
Offer — “Grab My [Freebie/Template]—I Made It for Busy Humans”
Tip: The buckets never change; only your headlines do. That’s how you stay fast.
Real-Life Prompts (steal these)
Teach: “Write 180 words teaching beginners how to set up a weekly content calendar in Google Sheets. Include 3 bullet benefits and one CTA to download my dashboard.”
Story: “Write a relatable mini-story about trying to ‘post whenever’ and how a 90-minute Sunday block lowered my stress. Keep it human and hopeful.”
Proof: “Summarize what Canva Magic Design did well and what I still had to tweak when producing four square graphics. 120–160 words.”
Offer: “Draft a simple CTA for my Starter Pack with a one-sentence value prop, zero hype, and a friendly nudge.”
Troubleshooting & Pro Tips
Captions sound robotic? Tell ChatGPT: “Short sentences. Punchier verbs. One micro-story. One emoji max.” Then prune adverbs.
Can’t finish in 90 yet? Shrink scope, not standards. Keep the Core-4; reduce each caption to 120–150 words. You’ll speed up by month two.
Hate design? Lock one template for the quarter. Only the headline changes.
Scheduling overwhelm? Start with one platform for 30 days. Nail the habit, then add a second.
Accessibility win: Add descriptive alt text (≤120 chars) to every image.

FAQs
Can you really batch a month in 90 minutes?
Yes—by limiting scope to four posts, using timeboxing, and leaning on templates for words and visuals. Consistency beats perfection.
Do you need paid tools?
No. ChatGPT, Canva, and Buffer each have free options. Paid tiers add speed and collaboration; the system still works without them.
What if my niche is super visual or highly technical?
Use Canva templates for structure and ask ChatGPT to “explain for beginners without dumbing down.” Add one concrete example from your world.
What’s a realistic posting cadence?
Start with weekly. When your sprint reliably fits 90 minutes, add a mid-month extra post. The goal is repeatable, not heroic.
