Gamma deck from a Claude research brief in 10 minutes

You have a research brief, a rough outline, or a document full of notes. You have a presentation due in two hours. The slow version of this is: open Gamma, type a one-line prompt into its "create from text" input, get back a generic 10-slide deck, spend 40 minutes editing every slide to actually reflect your content, swear, give up, do it in Google Slides instead.

The fast version uses Claude as the middle step. Gamma's "create from text" input accepts structured text input, and the quality of the output is entirely dependent on the structure of what you paste. If you paste a one-line prompt, you get generic slides. If you paste a properly structured outline with slide titles, bullet points, and speaker notes, you get a deck that is 90 percent finished on the first try. Claude writes that structured outline for you in about 30 seconds.

What you'll build

A two-step process that:

• Takes your rough notes or research brief
• Asks Claude to convert them into a Gamma-compatible structured outline
• Pastes the outline into Gamma to generate the deck
• Produces a finished presentation that actually reflects your content

No automation, no Python, no API keys beyond a manual Claude conversation. This one is deliberately pen-and-paper fast because decks are usually a "right now" problem.

Prerequisites

• A Gamma account on the Plus tier. The free tier works but caps deck length and limits some design options. Plus is £8/mo and gives you what you need for professional work.
• Claude access, either via the web app (free tier is fine) or the API. Most people should use the web app for this workflow because you want to iterate on the outline interactively.
• A rough brief, outline, or pile of notes. Even a hand-written sentence per section is enough.
• About 10 minutes per deck.

How to build it

Step 1: Write your rough brief

Before you talk to Claude, spend 2 minutes writing down what the deck needs to cover. Not slides, not structure, just the points in the order you want to make them. Something like:

CopyDeck for Monday's board meeting. 15 minutes max.

- Where we are: Q1 revenue, customer count, churn
- What worked: the enterprise pilot with Acme, new onboarding flow
- What didn't: paid search, outbound cold email
- Q2 plan: three bets (product, hiring, pricing)
- Risks: key dependency on Acme contract, cash runway
- What I need from the board: approval for the pricing change

This is enough for Claude to work with. If your brain dump is messier than this, paste it anyway; Claude is good at extracting structure from messy notes.

Step 2: Ask Claude for a Gamma-ready outline

Open Claude (web or API) and paste this prompt, with your brief at the end:

CopyYou are helping me build a presentation in Gamma. Gamma accepts
a structured text outline as input and generates a deck from it.
It works best when the input has clear slide boundaries, a heading
per slide, 3-5 bullet points per slide, and optional speaker notes.

Please convert the brief below into a Gamma-ready outline with:
- A title slide
- Between 6 and 10 content slides (aim for quality over length)
- A closing slide with a clear call to action
- Each slide formatted as:
  # Slide title
  - Bullet one (under 8 words if possible)
  - Bullet two
  - Bullet three
  (speaker notes for this slide, 1-2 sentences)
- British English spelling, no em dashes
- No marketing speak, no AI-cliche vocabulary
- Concrete numbers where the brief contains them

Claude will produce something that looks like this:

Copy- Where we are and what comes next
- 15 minute board update
(Opening slide. Set expectations on length and purpose.)

# Q1 headline numbers
- Revenue up 34% quarter on quarter
- 127 new customers, 12% net revenue churn
- Runway: 18 months at current burn
(Lead with the numbers the board cares about most.)

# What worked in Q1
- Acme enterprise pilot converted to annual contract
- New onboarding flow: activation up from 41% to 67%
- Shifted support to async-first, saving 12 hours a week
(Focus on one bet per point. Keep each claim tied to a metric.)

# What did not work
- Paid search: £18k spent, 3 customers acquired
- Cold email: 2% reply rate, zero conversions
- We are pausing both and redeploying the budget
(Be specific about the waste. Board respects honesty here.)

# Q2 plan: three bets
- Ship the tiered pricing change by 15 May
- Hire 2 engineers and 1 customer success
- Run one more enterprise pilot with a public logo
(These are the three things we will be judged on next quarter.)

# Risks on the radar
- Acme contract is 23% of ARR, renewal in Q3
- Engineering hiring is currently 6-8 week timeline
- Cash runway tightens if pricing change slips past Q2
(Lead with the biggest risk. Do not understate.)

# What I need from the board
- Approval for the pricing change proposal (1 slide backup)
- Green light on the additional hires
- Introductions to 2 enterprise prospects
(Close with a concrete ask. Do not leave the decision implicit.)

# Thank you
- Questions?
(Closing slide. Keep it simple.)

Review the outline. If Claude misread your brief or put the wrong emphasis on a slide, just reply in the same conversation with a correction ("make slide 4 more specific about the Q2 pricing change") and it will revise.

Step 3: Paste into Gamma

Open Gamma. Click Create new → Presentation → Paste in text. Paste the entire outline, including the speaker notes in parentheses. Gamma will parse the markdown headings as slide titles, the bullet points as slide content, and the parenthetical notes as speaker notes.

Pick a theme. Gamma has about 20 built-in themes and they are all fine. For board decks I default to the "Oatmeal" or "Blanc" themes because they are understated. For investor decks I use "Obsidian" or "Peach". For customer-facing decks I match the theme to the customer's brand by picking one with similar colours.

Click Generate. Gamma takes 30-45 seconds to produce the deck. When it is done, you have 8-10 finished slides with the structure Claude wrote, styled with the Gamma theme you picked, and auto-selected cover images from Gamma's stock library.

Step 4: Polish

The deck is 80-90 percent of the way to ready. Spend 5 minutes on the last mile:

1. Replace any generic stock images with your own screenshots, charts, or diagrams. Charts in particular should be your own Excel or Numbers exports, not Gamma's placeholder charts.
2. Check every number against your source. Claude occasionally typos a figure when transforming your brief, and the consequences of a wrong number on a board slide are severe.
3. Remove any slide that feels thin. Seven strong slides beats ten mediocre ones, and Gamma tends to err on the side of more.
4. Fix any tone issues. Gamma's themes sometimes impose a slightly more formal voice than you want.

Total time from "I need a deck" to "I have a deck": about 10 minutes if your brief is ready, 15-20 if you need to write the brief first. That speed creates its own risk. A deck built in 10 minutes is a deck you have not thought very hard about. Use this workflow when the thinking is already done and the bottleneck is the production, not when you are trying to work out what you want to say.

Cost breakdown

• Gamma Plus: £8/mo
• Claude: free on web, or roughly 2-5 pence per deck on the API if you run this programmatically
• Total marginal cost per deck: about £8/mo flat, near zero per deck on top of the subscription

Gamma decks are optimised for short, modern, image-heavy presentation styles. They are great for startup board decks, conference talks, internal updates, and pitches. They are less good for data-dense academic slides, reports formatted as decks, or decks that need strict brand compliance (specific colour values from a style guide, licensed fonts, hard-coded logos on every slide). For those, either build in Keynote or PowerPoint from scratch, or build in Gamma first and then export to PowerPoint and retouch the branded elements manually.
