Manus AI Slides: How to Build a Deck You Can Still Edit

Manus AI builds a full presentation from one prompt or a folder of files. It researches the topic, drafts the slides, writes speaker notes and hands back an editable PowerPoint (.pptx) file, a PDF, interactive web slides and a separate speaker-notes document ^[1]. Manus puts a typical deck at about 5 to 15 minutes: roughly five for a simple 10-slide deck and fifteen for a 40-slide research deck. The decision that matters most comes before the prompt. Standard and PowerPoint modes give you slides you can still change; Nano Banana Pro gives you striking slides that are flat images. Pick the mode first. Then check every number.

Choose the slide mode before you type a prompt

The Slides tool offers three modes: Standard, Image (high-impact visual slides powered by GPT Image 2) and PowerPoint. Standard builds HTML slides that you edit inside Manus and export later. PowerPoint mode, launched in Beta in July 2026, writes a native .pptx file directly instead of converting a web format at export time ^[2]. Its charts keep an embedded data table, so you can change the figures inside Manus with the Elements and Edit Data controls, or later in PowerPoint or Google Slides. For a deck that someone in finance will open and adjust, that is the safer starting point.

Nano Banana Pro is a separate image-slide option, not the same thing as Image mode. The image model from Google built into Manus has been open to all Manus users since December 2025. Each slide comes out as a single high-resolution image with the text rendered into the picture, so nothing on it can be edited yet ^[3]. A deck usually lands in about 2 to 5 minutes. Manus itself recommends this route for high-impact decks such as pitches, launches and keynotes, and the HTML slides for data-heavy content that changes often. A simple test helps here. If anyone will need to change a figure after the meeting, stay with an editable mode.

Give Manus the material, not just a topic

A topic alone sends Manus off to research on its own, which is fine for a briefing but risky for a deck built on your numbers. The stronger route is to hand over the source. Data analysis accepts PDF, CSV and Excel files and can deliver a slide deck, a dashboard, a report or a webpage, with up to five chart types per analysis. Connect a Google Workspace account and Manus can pull Google Sheets data straight into the slides, or research a topic and output the deck in the same task. Google Drive, Notion and local files also work as sources.

Several entry points skip the upload step entirely. Mention @Manus in a Slack thread and the conversation becomes a deck (the AI features inside Slack need a paid Slack plan, and teammates need Manus accounts). Forward an email with attachments to your personal Mail Manus address and Manus builds a presentation from it, though those tasks use credits like any other. Meeting Minutes, which identifies speakers and assigns action items, can feed its notes into a presentation in the same task; the recording is free, the analysis costs credits. Each route ends in the same Slides tool, so the mode choice above still applies.

Before Manus designs anything, turn on Plan Mode. On the web you type a slash and select Plan; on mobile you tap the plus button. Manus then writes an editable Markdown plan and will not start building until you confirm or dismiss it. For a deck, this is where you fix the outline, the slide count, the order of the argument and the audience. Plan Mode is manual, open to every user, and can be switched on mid-task. Manus also advises specific requests over vague ones and splitting complex work into smaller tasks, since vague asks tend to cost more.

Put your brand on every slide

The quickest route to an on-brand result is your own template. Import a PowerPoint (.pptx) file and Manus applies its layouts, colors and fonts to the new deck. If your team builds decks every week, place the template and the house rules inside a Project. A Project holds a master instruction plus a knowledge base, and you can create as many as you need on any tier. One detail trips people up. Instruction changes reach running tasks at your next message, but file changes reach only tasks created afterwards, so a refreshed template needs a fresh task.

Teams get one more lever: the Team plan adds shared slide templates alongside usage analytics and SSO, which carries a flat $150 fee (plus tax) for teams under 30 seats and is free from 30; confirm the billing period with Manus. Manus drafts speaker notes slide by slide, and they export as their own document. When the deck carries charts, upload the spreadsheet rather than pasting numbers into the prompt. Manus analyzes the file, picks out trends and builds the charts directly in the slides, which keeps the figures traceable to a file you control. In PowerPoint mode those charts stay editable after export.

Get the deck out as PowerPoint, PDF or Google Slides

The documentation lists four outputs: editable .pptx, PDF, interactive web slides and a speaker-notes document. The marketing page adds conversion to Google Slides and saving to Google Drive or OneDrive. Where you receive the deck changes the format. In Slack and in LINE, slides arrive as a PDF, so open the task itself when you need the editable file. If your team already lives in Google Slides, the Google Drive connector lets Manus edit there directly: it can replace text, reply to comments, add slides and update speaker notes, and deletions ask for confirmation first.

Developers can pull the same file over the API, where slides attachments come back as PowerPoint when the request sets the slides format to pptx. On ownership, Manus's help center says you own the slides you create and may use them commercially, while warning that AI output may not be unique or protectable. Download the final file as soon as it is approved. Manus's pages disagree on what survives a sandbox reset, so a local copy is the only version you control. Deleted tasks cannot be recovered either.

Credits and time: what one deck costs you

There is no fixed per-slide price. Slide work, like every Manus task, burns credits according to complexity, length and the number of images generated. Manus states plainly that it cannot estimate a task's credit cost in advance, and it tells users to treat any credit figure the agent quotes as a hallucination ^[4]. The practical answer is to check Settings, then Usage, after each deck and learn your own pattern. Unused monthly plan credits do not roll over, on monthly or annual billing.

Free accounts run only Manus 2.0 Lite in Agent mode. They receive 300 refresh credits a day, usable only in Lite and capped at 1,500 a month, which by our arithmetic is five full days of refresh credits, plus 1,000 credits once at sign-up. Manus's Canva comparison page says PPTX and PDF export are on every plan, including Free. Our guide to Manus AI's free plan covers those limits in full. Pro at $20 a month (4,000 credits) adds Manus 2.0 and Manus 2.0 Max for heavier research decks.

Collaboration changes who pays. In Collab, up to 50 people can work in one task, everyone sees the full task history, and only the task owner spends credits. Connectors switch off once a task is shared, so a teammate cannot lean on your Drive or Sheets link mid-deck. If a deck fails through a verifiable platform fault, Manus refunds the credits after an AI review that needs a shareable task link. Manus's help pages disagree on whether a poor result, such as a weak design, qualifies; confirm with Manus in writing before you count on it.

Where Manus slides stop

Manus's own Canva comparison page names two hard limits. There is no live co-editing on a shared canvas, and the tool produces digital files only, with no CMYK export for print. If your deck goes to a print shop or gets built by five people at once, finish it in PowerPoint or Google Slides after export. That handoff works cleanly only from the editable modes.

Accuracy is the bigger risk. It is real. Manus warns that the agent can produce confident but inaccurate statements and can invent papers or citations, and its Terms require you to review all output. A research deck therefore needs a source check on every chart and quote before it reaches a client. Analysts building decks from many sources will find the research workflow covered in Manus AI for researchers. Ad teams can pair Slides with the read-only Meta Ads connector, whose 30-day audit ends in a slide deck; Manus AI for marketing teams walks through it.

The bottom line

Manus AI is a fast way to reach a researched first draft of a presentation, with speaker notes and charts built from your own files. The value depends on three choices you make up front: an editable mode unless the deck is purely for show, your own template and data files instead of a bare topic, and Plan Mode before any design work. Budget credits by watching usage, not by asking the agent. Then treat the export as a draft that still needs a human pass on every number.
