Built for people whose slides get interrogated
Principles
What we believe about building great decks with AI
AI shouldn't replace you, it should enhance you
No AI will ever have the context, the history, and the judgment your deck needs, so we shouldn't expect it to create great work independently. Instead, AI should enhance your slides, strengthen your arguments, and review with rigor.
The best decks start from proven existing work
Slides are generally new arrangements of visualizations you've already perfected, so that work should be your starting point. Your best material should be instantly accessible, instead of rebuilt from scratch.
Review matters as much as creation
One small error derails the best deck, so thorough reviews are critical. AI reviews drop context, miss errors, and hallucinate, so checks should be mechanical wherever possible.
Everything should happen inside PowerPoint
Your workflow lives in PowerPoint and so do your colleagues. Everything SlideBrain touches is a native, fully editable element. Nothing proprietary, nothing to install to view.
Assistant
An assistant that understands and fixes your slides
- Plain English in, real edits out. Simply chat like a human and get a precise edit in the deck.
- Review and find issues. Identify issues and get tailored suggestions, not just generic tips.
- Fix issues in one click. Automatic client-ready fixes without lifting a finger.
Smart Charts
Charts built like you'd build them. Just faster and better
- Automatic charting. Share the data and get a client-ready chart built to your standards.
- Always on brand. Colors, fonts, and formatting follow your rules, not the defaults.
- Native PowerPoint. All charts are inserted as native and editable PowerPoint elements.
Component Builder
Assemble slides from proven parts
- Save any slide or element. Turn your polished slides and elements into reusable components in one click.
- Search like you'd ask a colleague. Describe what you want to do in plain English and get a tailored suggestion.
- Start with 300+ built in. Proven templates and components from day one, before your own library grows.
Auditor
Find every mistake before your stakeholders do
- Audit every number. Numbers, calculations, and references checked against each other across the whole deck.
- You control what gets checked. Set the scope and rules so the right errors are identified.
- Nothing changes without you. Findings are surfaced but you approve anything that touches your message.
Trust and accuracy
Built for decks where trust and accuracy is the product
Nothing moves without your approval
SlideBrain flags, drafts, and fixes, but you review, approve, and present. Anything that changes your message shows a visible preview and takes exactly one click to approve.
Every edit comes with a receipt
Each change lands in the deck with a record of exactly what changed and where, in a log that travels with the file. No silent edits, no surprises in the room.
Native PowerPoint and fully editable
Everything SlideBrain touches stays a standard, editable PowerPoint object. Colleagues without the add-in notice nothing, and your file works everywhere it always has.
Security and compliance
Your deck is never uploaded and never trained on
Your file is never uploaded
SlideBrain reads your deck on your machine, inside PowerPoint. Slide content is only temporarily shared with AI when needed, such as when you ask for a review.
Nothing stored unless you save it
We store only what you explicitly tell us to, everything else is processed in memory and discarded.
No training on your data
Our AI provider does not train models on your content, under a formal data processing agreement. Zero-data-retention processing is available on request.
GDPR-compliant architecture
Accounts and infrastructure are hosted in the EU. AI requests are processed by Anthropic under a data processing agreement.

Frequently asked questions
Your questions, answered
Does SlideBrain upload or store my presentations?
No. Your deck is read on your machine, inside PowerPoint. We store only what you explicitly save, and our AI provider does not train models on your content.
Will my slides still work for colleagues without SlideBrain?
Yes. Everything SlideBrain creates or edits is a standard, editable PowerPoint object. No plugins required to view, edit, or present.
Can SlideBrain follow our company's style guidelines?
Yes. Colors, fonts, chart styles, and formatting rules are captured once, then every edit, chart, and component lands inside your guidelines.
Can I try SlideBrain before paying?
