Founders often group these products together because they both touch the pitch deck. They do very different things to it. Slidebean's job is getting slides to exist and look right. It sells software, plus a team of analysts, storytellers and designers who will do the deck or the financial model for you.
Nautis starts after the slides exist. You upload a PDF, and it comes back with a score out of 100, feedback, likely investor questions and a tracked link. It also has an answer for what happens around the deck, from the investor pipeline to runway. Read on for what each one offers, as published by Slidebean on its site in October 2026.
Do you have a deck yet?
If not, Nautis can't help you make one, and we'd be wasting your time to imply otherwise. Its guide says so directly: you make changes in your slides tool, such as Keynote or Google Slides, then upload again. Slidebean's Beta AI generator can start a deck from your website or a short prompt, its automated design handles layout as you add content, and its templates give you a structure to work from. If you prefer to start with the story, our fundable pitch deck guide and pitch deck outline generator cover that for nothing.
If you already have a deck, Slidebean's FAQ notes that it can't import decks in other formats. You'd be rebuilding from a template to use its editor. So a founder happy with Google Slides doesn't need to move, and a separate review tool may be all that's missing.
What each does to the deck
| Deck stage | Slidebean | Nautis |
|---|---|---|
| Create the content | AI pitch deck builder, from a website or prompt | No builder |
| Design the slides | Automated design and 100+ templates | No editor |
| Review the deck | Unlimited AI pitch deck reviews on Starter | AI score, storytelling and clarity notes, slide recommendations |
| Pressure-test the idea | Not listed | Idea Validation tab tests market, demand signals and risks |
| Prepare for questions | Monthly coaching calls on Accelerate | Investor Questions tab, with hints for answers |
| Rehearse out loud | Not listed | AI Voice Coach: full pitch, rapid Q&A, term sheet negotiation, mock IC |
| Video version | Not listed | Video Pitches with teleprompter, topic clips and CTA |
| Share and track | Track views, slide by slide | Tracked links, passcodes, watermark, expiry, revocation, per-link analytics |
| Human help | Calls on Accelerate, plus agency services | None. Advisors in the app are AI |
| Financial model | Forecast tool and bootcamp, plus a modelling team | Financial Planner with projections and exports |
| Investor search | Investor Finder with profiles, no contact details | Find Investors with match score, and a CRM |
The top three rows are the essence of it. If you only remember one thing from this table, remember that a Nautis score doesn't produce a slide, and a Slidebean template doesn't make you ready for a partner's third question.
Slidebean prices and what they buy
Slidebean has two subscription plans on its pricing page. Starter is $7 a month billed yearly, or $12 billed monthly, going by the page's own pricing script. Accelerate is $99 a month, monthly only. The page doesn't say whether these prices are per user or per account. These are figures as of October 2026. Agency rates aren't on the pricing page, but its design page lists a deck redesign of up to 20 slides at $799 and a strategy and deck sprint starting at $6,000.
- $0 sign-up. The FAQ describes a trial with no card and no time limit, in which you can create presentations but can't share or download them until you pay. That is enough to judge the editor.
- Starter. AI builder, templates, view tracking, unlimited AI reviews, a financial modelling bootcamp and a cap table template or tool.
- Accelerate. A strategy call with the CEO, Investor Finder and CRM tools, a financial modelling forecast tool, and monthly prep sessions with its team. The plan list shows a 30-minute writing session and a 30-minute modelling session each month.
- Nautis. $49, $99 or $129 a month, with a 14-day trial and no $0 tier. The Pitch Deck Analyzer uses AI credits whenever a deck is processed, and an AI Voice Coach session has a recording time limit set by your plan.
The page's FAQ mentions the Investor Finder under Starter, and its plan list shows it under Accelerate, so check which plan includes it if that feature matters to you.
A deck timeline that uses both
- Week one. Draft the story. Build the slides in Slidebean, or in whatever you already use. Export to PDF.
- Week two. Upload the PDF to Nautis. Read Recommendations and fix the weak slides in your original tool, because Nautis can't edit them. Re-upload, since the score only changes after a new analysis.
- Week three. Start the AI Voice Coach with the deck attached, so follow-up questions reference your actual slides. Do Full Pitch first, then Rapid Q&A. Read the transcript and scorecard, and rewrite your weak answers.
- Week four. Share a private link with a passcode and watermark to your first investors, and add them to a round in the Fundraising CRM. The Manage tab shows sessions, time and slides watched.
Nothing says you must buy Nautis for that review. Our free deck analyzer is a lighter way to get a first read, and if deck review is your only need, Slidebean Starter includes AI reviews too.
Nautis vs Slidebean when budget is tight
Say you have $150 to spend on your pitch this month. Slidebean Starter on monthly billing leaves plenty over, and it gets you a finished, shareable deck with tracking. You lose out on rehearsal and on a joined-up pipeline, but you can get those from a spreadsheet and a friend who will grill you.
Nautis Launch costs $49 and adds a workspace, although investor deals are limited on that plan and the cap table starts on Voyage at $99. Either way, you'd still need a slides tool. So if your whole problem is slides, Slidebean gets you further for less. Nautis starts to make sense when your problem has become everything that follows: who has the deck, whether you can afford the time, and what the raise is doing to the rest of the business.
Strengths and gaps on each side
Slidebean
- It produces the actual artifact, which Nautis doesn't.
- Human analysts and designers are available, and its homepage says its agency has delivered 500+ projects over ten years.
- Its Trustpilot reviews and long history give you outside opinions to check. Nautis, public since July 2026, has few independent reviews.
- The modelling bootcamp teaches a skill you keep.
Nautis
- Rehearsal is a real strength, because you practice a live conversation with an AI investor persona and get a scorecard.
- Your deck connects to your round, data room and Investor Readiness score.
- The rest of the company runs in the same workspace, which a deck tool isn't trying to do.
- Gaps remain: no slide creation, and the score reflects what it calls late-stage expectations, so pre-revenue decks often score low. Read the recommendations and don't obsess over the number.
What to do next
- No deck yet: start in Slidebean or your favourite slides tool. Don't open Nautis for this.
- Deck done, raise starting: try Nautis for the review, the rehearsal and the pipeline, or use its free analyzer first.
- Want someone to do it for you: talk to Slidebean's services team. Nautis has no equivalent.
- Already paying for both kinds of tool: keep creation and review separate, and keep one investor list.
FAQ
Which is better for making a pitch deck in Nautis vs Slidebean?
Slidebean. It has an AI builder, automated design and 100+ templates. Nautis doesn't create or edit slides: it analyses a PDF you built elsewhere, so you need a slides tool either way.
How much does Slidebean cost?
As of October 2026, Starter is $7 a month billed yearly, with its pricing script showing $12 billed monthly, and Accelerate is $99 a month. A no-card sign-up lets you create decks, but sharing or downloading needs a paid plan. Agency prices are separate: its design page lists a deck redesign at $799 and a strategy and deck sprint from $6,000.
Can I upload my existing deck into Slidebean?
Its FAQ says uploading decks or documents in other formats isn't possible, and suggests using its templates as a head start. Nautis accepts existing decks as PDFs up to 50MB, but only for analysis and sharing.
Can I practice my pitch in Nautis?
Yes. The AI Voice Coach holds a spoken session with an AI investor in one of four modes, then scores you out of 100 across 11 dimensions, with rewrites and speech analytics. Each session has a recording time limit set by your plan and uses AI credits.
