ON ONE BOARD
Quick answer
  • Pick Context Board if your deck comes from work you already keep. Claude turns the launch plan page into slides, and Codex adds an MRR chart that follows your sheet.
  • Gamma designs a deck, doc or site from a prompt, with its own AI agent and connectors for Claude and ChatGPT. Plus is $9 and Pro $18 a seat a month, billed yearly, with monthly AI credits.
  • Context Board is $12 a month after a 3-day trial, for slides, docs, sheets and dashboards in one workspace, with no AI credits to buy.

Context Board vs Gamma: the verdict

Context Board is the better pick when the deck is part of your work, not a one-off. A Slides board sits in the same workspace as your docs, sheets and dashboards, so Claude can turn the launch plan into slides and Codex can add a chart that changes when the sheet does, each slide signed with the agent's name. Present from the board, or download PowerPoint or PDF. Gamma is the quicker road to a designed deck from a single prompt, priced per seat with AI credits. Free for 3 days, then $12 a month.

Where Context Board wins
  • Slides beside the workA Slides board lives in the workspace that holds your docs, sheets and dashboards. Ask Claude to turn the launch plan into a deck and it reads the page, writes the slides and their speaker notes, and each slide shows that Claude wrote it.
  • Charts that follow the sheetA chart on a slide can take its numbers from a Sheet board and changes when the sheet does. A widget on a slide, like MRR from Stripe, stays live while you edit, present and share.
  • Your agents, no creditsClaude, ChatGPT, Codex, Cursor and Grok read and write decks over MCP on the plans you already pay for. $12 a month covers every kind of board.

Context Board vs Gamma: the full comparison

You have a product update on Thursday. The numbers are in a sheet, the launch plan is a doc page, and what shipped is in your notes. Gamma will design a good-looking deck from a prompt, once you hand it those facts.

Context Board starts from the other end. Its Slides boards sit in the same workspace as your docs and sheets, and your own agents write the deck from them. Context Board is ours, so weigh the bias. Gamma’s prices below were read on its own pages on November 4, 2026.

A deck in the same workspace as your work

An example Slides board named Product update: four slides down the left, and slide 3 open, an MRR chart Codex wrote that reads the Running costs sheet, with the deck's menu open on its downloads. Every name and number on it is example data.

Slide 3 is a chart from a sheet, so it changes when the sheet does. The ⋯ menu brings a deck in and takes it out. Example deck, example numbers.

The slides run down the left, and you type straight onto the open one. Speaker notes sit under it. Layouts like Title, Two columns, Big number and Widget come in Paper, Night, Bold or Editorial.

Ask Claude to “turn the launch plan into a slide deck.” It reads the page, writes the slides and their notes, and each one shows that Claude wrote it. Ask Codex for “a slide with the MRR chart” and the chart takes its numbers from your Running costs sheet. Change the sheet and the slide follows. A widget on a slide, like MRR from Stripe, stays live while you present.

Press P and the deck fills the screen from the open slide. Presenter view keeps your notes, the next slide and a timer in front of you. The Slides docs list every layout and key.

How a deck gets made on the board

  1. Ask Claude: turn the launch plan into a slide deck
  2. It reads the page and writes the slides, signed
  3. Codex adds the MRR chart from your sheet
  4. Press P to present, or download a .pptx

The ask can come from the board’s own chat, which runs on your Claude Code or Codex plan, or from any app you connect over MCP. Every change lands in Board activity with the agent’s name and an Undo.

What your agents can do in each

An agent on Context Board
  • Reads the deck, your doc pages and your sheets
  • Writes a whole deck from Markdown, or slides after any slide
  • Sets layouts, styles, speaker notes and charts
  • Runs on the plan you already pay for
An agent in Gamma
  • Generates a gamma from a prompt, through Gamma’s connector
  • Edits an existing gamma, from Claude or ChatGPT
  • Exports PDF, PPTX or PNG
  • Spends Gamma credits on each generation and edit

Gamma has AI of its own and a strong agent story. Its hosted MCP server works on every plan, and it powers the Gamma connectors in Claude, ChatGPT and Slack. The difference is where the deck lives. In Gamma, your agent makes a gamma. On the board, your agent works on the same pages, sheets and numbers you do, and the deck is one more board beside them.

What it costs

A year, for one person
Context Board, every kind of board$144
Gamma Plus, one seat, 1,500 credits a month$108
Gamma Pro, one seat, 4,000 credits a month$216

Gamma’s yearly prices from its pricing page on November 4, 2026. It says yearly billing saves up to 28% on monthly. Context Board is $12 a month.

Context Board’s $12 a month covers the whole workspace. That’s the deck, the doc it came from, the sheet behind the chart and the dashboard with your live MRR. Gamma’s seat covers decks, docs and sites, with its AI on monthly credits. On the board there are no credits to watch, because your agents work on the plans you already have.

Where Gamma still fits

Pick Gamma when you want a designed deck, doc or web page from one prompt and don’t have the material written down yet. It makes the whole thing at once, with AI images and a theme builder, publishes sites on your own domain from Pro, and shows who viewed what. It also suits a team that shares brand themes across seats.

Context Board is built for one person and their agents, with no team plan or seats. If your decks come from work you already keep, start there. The Claude slides guide compares every way to make slides with Claude.

Try it with your next update

Make a Slides board and ask your agent to turn this week’s notes into five slides, with the MRR chart from your sheet. Press P. If it is the deck you would have built, you’ve saved the copying.

Frequently asked questions

Something else on your mind? Get in touch.

Is Context Board a Gamma alternative?

For decks you make from your own work, yes. A Slides board holds a deck you and your agents write, with layouts, speaker notes, charts from a sheet, Present and Presenter view, and PowerPoint and PDF downloads. It doesn't design a whole deck with AI images from a one-line prompt the way Gamma does.

How much does Gamma cost?

Gamma's pricing page showed a Free plan with 400 credits at sign-up, then Plus at $9, Pro at $18 and Ultra at $90 a seat a month, billed yearly ($108, $216 and $1,080 a year), on November 4, 2026. It says yearly billing saves up to 28% on monthly. Its help center lists Business at $40 a member a month, billed yearly.

Can Claude make a deck in Context Board?

Yes. Add the board to Claude, ChatGPT, Codex, Cursor or another MCP app by its address and sign in on an Allow page. Ask it to "turn the launch plan into a slide deck" and it reads the page, writes the slides and their speaker notes, and each slide it writes shows its name. Gamma also has connectors for Claude and ChatGPT, on every Gamma plan.

Can I import and export PowerPoint?

Yes. Import a PowerPoint and its text boxes, shapes, pictures, tables, charts, backgrounds and speaker notes come in. Anything it can't bring, like video and sound, is listed by slide. Download the deck as PowerPoint (.pptx), PDF, PDF with notes or Markdown. From Google Slides, download the deck as PowerPoint first.

Do the charts on my slides stay up to date?

A chart can take its numbers from a range on a Sheet board, and it changes when the sheet does. A widget on a slide, like MRR from Stripe, stays live while you edit, present and share. Gamma's Smart Charts can connect to a Google Sheet tab and update when you click Sync.

What does Context Board cost?

Free for 3 days, then $12 a month for the whole workspace: slides, docs, sheets, dashboards and every other kind of board. Your agents work on the plans you already pay for, so there are no AI credits to buy.
