Stage-aware scoring
Score is calibrated to Idea Stage, Pre-Revenue, or Post-Revenue so feedback matches investor expectations.
Pitch Deck Analyzer: score the deck, fix it, then see who reads it
Run any investor deck through a deep AI review. You get a readiness score out of 100, slide-by-slide feedback, storytelling and clarity notes, suggested investor questions, and a tracked link to share with VCs.

What is Pitch Deck Analyzer?
Pitch deck analysis software reads an investor deck and tells you what to fix before an investor does. The Nautis Pitch Deck Analyzer takes a PDF up to 50 MB, judges it against your product stage, and returns a score out of 100, storytelling and clarity notes, slide-by-slide recommendations and the questions investors are likely to ask. When the deck is ready, you send it on a tracked link.
Investors rarely tell you why they passed on a deck. You send it, you hear nothing, and you guess. The analyzer exists to move that feedback earlier, to the night before you hit send, when you can still change the traction slide or cut the third market-size chart.
You pick one of three product stages when you upload: Idea Stage, Pre Revenue or Post Revenue. That choice sets the bar. A pre-revenue deck that leans on customer interviews gets read differently from a post-revenue deck that buries its MRR on slide 11. Expect a lower score before revenue. That's normal, and the Recommendations tab is where to spend your time, not the number.
The second half of the module is distribution. Every deck gets a Share button with three tabs: Get link, Email invite and Manage. Each link can be Public or passcode-protected, can expire, can block downloads and can carry a watermark. Manage shows sessions, total time, average slides watched and when each link was last viewed. If you're still deciding what goes on the slides at all, start with our guide to a fundable pitch deck and come back with a draft.
Built for

Capabilities
What you can do with Pitch Deck Analyzer
Everything ships out of the box. No setup, no plugins, no extra tools.
Slide-by-slide notes
Specific suggestions on every slide — what's missing, what's unclear, what to cut.
Investor question generator
AI lists the questions a VC is most likely to ask, so you can rehearse.
Tracked share link
Send the deck via a tracked URL and see sessions, total time, average slides watched and last viewed for each link.
Cached re-uploads
Re-upload the same PDF and the analysis loads instantly from cache.
Use cases
How startups use Pitch Deck Analyzer
The night before your first partner meeting
Upload the PDF, pick Pre Revenue, and go straight to Recommendations. Fix the two or three slides it flags hardest in Google Slides or Keynote, export again, and use Retry to run a fresh analysis. The score only moves after a new run, so don't judge progress until then.
Sending the deck to one named investor
Create a Private link with a generated passcode, set it to expire in 1 week, turn off Allow download, and put the partner's name in both Recipient name and Watermark. If it leaks as a screenshot, you'll know whose copy it was. Revoke it from Manage once the conversation ends.
Pressure-testing an idea-stage story
On an Idea Stage deck, open Idea Validation and click Start Idea Validation. It runs a separate AI pass on market, demand signals and risks. It takes a couple of minutes and some credits, and it's the closest thing to an honest friend reading the problem slide.
Drilling the Q&A you'll actually face
Read the Investor Questions tab with its answer hints, then open the AI Voice Coach, attach the same deck, and say the answers out loud in a Rapid Q&A session. Questions grounded in your own slides are harder to wing.
Sharing the review with an accelerator mentor
Click Export PDF to download the full analysis report. Your mentor reads the scoring breakdown and notes without needing a Nautis seat, and you keep the deck itself off their inbox.

What the AI does in pitch deck analysis
On upload, Nautis converts the slides to images, extracts the text and runs one full AI analysis. That pass produces the score, the Overview summary, Storytelling & Clarity, Recommendations and Investor Questions. The header names the AI provider used, so you know what read your deck.
Idea Validation is a second, optional pass you start yourself. Both runs use AI credits, as does Retry analysis. If you upload the exact same PDF twice, Nautis spots it and loads the existing result instantly, marked as cached, which costs nothing and changes nothing. Change the file if you want a new opinion.
The analyzed deck also feeds Investor Readiness, where your best deck score is one of the signals in the Pitch Deck category.
Pitch deck analysis software vs a quick free check vs a human reviewer
You'll probably use more than one. The question is which one you trust for which job.
| Job | Free one-off check | Nautis Pitch Deck Analyzer | Experienced human reviewer |
|---|---|---|---|
| A score to track between drafts | One score per upload | Score out of 100, rerun with Retry | Rarely a number |
| Slide-level fixes | A few top issues | Recommendations slide by slide, plus Slides tab with extracted text | Yes, if they have time |
| Judged against your stage | Sometimes | Idea Stage, Pre Revenue or Post Revenue | Depends on their background |
| Likely investor questions | Usually not | Investor Questions tab with answer hints | Yes, often the best part |
| Tracked sharing | No | Public or Private links, expiry, watermark, per-link analytics | No |
| Context on the people you're pitching | No | No | Yes, and that's hard to replace |
Plans and limits
- The Pitch Deck Analyzer must be enabled on your plan. Each analysis, Idea Validation run and retry uses AI credits, which are capped monthly by plan (1,000, 2,000 or 2,600). See pricing.
- Uploading needs create permission on the Pitch Decks module and a verified email.
- Every plan starts with a 14-day trial with no card.
What Pitch Deck Analyzer doesn't do
- It reads PDFs only, up to 50 MB. Export from your slides tool first. You can't edit slides inside Nautis.
- Once a deck reaches COMPLETED, you can't delete it from the UI. Delete is only there while a deck is still processing or failed.
- A Public link is protected only by the URL itself. Treat it like a public web page and use Private for anything with real numbers in it.
- The score is an AI read against stage expectations. It doesn't know the partner you're meeting or their fund's thesis, so a warm intro and a human read still matter more.
Pitch Deck Analyzer questions
What does pitch deck analysis software actually check?+
In Nautis it checks narrative and clarity, slide-by-slide content and the questions your deck invites. You get a score out of 100, a scoring breakdown on Overview, notes on Storytelling & Clarity, and concrete fixes on Recommendations.
Does uploading the same deck again give me a new score?+
Not if it's the identical PDF. Nautis recognizes it and loads the cached analysis instantly. Edit the deck and upload the new file, or use Retry on the deck card to force a fresh run, which uses credits.
Can I see which investor opened my deck?+
Yes, per link. Create one link per investor and fill in Recipient name. Manage then shows whether each link was viewed, with sessions, total time, average slides watched and last viewed time.
Is the free Pitch Deck Analyzer the same thing?+
It's a lighter version. The free deck check gives a score and your top issues without signing up. The in-app module adds the full tabs, Idea Validation, tracked sharing and the link to your raise.
Should I send investors my readiness score?+
Usually not. Show readiness score is off by default on share links, and most founders should leave it off. The score is a tool for you, and an investor reading 62 out of 100 learns nothing useful about your company.
How long does an analysis take?+
Usually one to three minutes, longer for big decks. Keep the processing dialog open; it walks through uploading, converting slides, extracting text and the AI run, then sends you to the deck's page.
How long does the AI analysis take?+
Usually one to three minutes, depending on the slide count and current load. Keep the upload dialog open until you're redirected.
Why does the score feel harsh?+
The AI grades against what late-stage investors typically expect. Pre-revenue decks usually score lower than post-revenue ones — that's normal. Look at Recommendations for the specific gaps and fix those first.
What file formats are supported?+
PDF only, up to 50 MB. Export from Keynote, PowerPoint, Google Slides, or Pitch as PDF and upload.
Can I edit the deck inside Nautis?+
No. The analyzer reads your PDF and gives feedback. You make changes in your slides tool (Keynote, Google Slides, etc.), then re-upload.
Will investors see the AI score?+
Only if you toggle Show readiness score on the share link. By default it's off.
Can I track who has viewed my deck?+
Yes. Open the share dialog, go to Manage, and you'll see per-link sessions, total time, average slides watched, and last viewed time.
What if my deck has confidential numbers?+
Mark the link Private, add a strong passcode, set a short expiration, turn off Allow download, and add a Watermark with the recipient's name. Revoke the link from Manage when you're done.
Does the AI see my deck content?+
Yes. It processes the slides to score them. Decks are stored privately in your organization until you choose to share, and only members with access to the Pitch Decks module can browse them.
Can I share a deck without granting Nautis access?+
Yes. The tracked share link works without a Nautis account. A Public link opens for anyone with the URL; a Private link also asks for the passcode.
