9 AI Startup Landing Page Examples, Scored and Critiqued

Looking at good ai startup landing pages is useful, but "this looks nice" doesn't tell you why a page works or what it still gets wrong. So we ran 9 homepages from well-known AI startups through PageCritic, the same audit anyone can run for free, and published the results as they came out: the overall conversion score, 7 sub-scores, each page's biggest issue with a concrete fix, and one thing it does well.

Audited on 2026-10-18. Scores are an AI's opinion of conversion best practices, based on desktop and mobile screenshots plus the page's HTML. They aren't measured conversion rates, and these companies didn't ask for a review. Pages change often; each link below goes to the full free report with the screenshots we judged.

We left out perplexity.ai, lovable.dev and gamma.app, which showed our browser a Cloudflare bot check instead of the page, and otter.ai, whose hero had not rendered when we took the screenshot. Scoring those captures would have been unfair.

The scores

What the patterns say

• Weakest area on average: Mobile (66), then Clarity (71). Even well-funded AI companies leave points on the table here.
• Strongest area: Design (82). Slick visuals and demos are standard in AI. They don't make up for a vague headline or a buried call to action.
• Headlines are too vague. On 7 of 9 pages, the headline was one of the top 3 issues: it names a category or a slogan instead of saying what the product does and for whom.
• Proof stays below the fold. On 5 of 9 pages, missing social proof on the first screen was one of the top 3 issues, even where the company has plenty of customers to quote further down.
• The product is hidden. On 5 of 9 pages, the first screen shows an illustration or nothing at all instead of the actual product.
• The common fixes are cheap. Most top issues are copy and layout: a headline that says what the product does, a line of proof under the hero, a short note under the button. None of them needs a redesign.

Page by page

synthesia.io: 78/100

A polished category-defining enterprise page whose hero headline is overly generic, muting the dramatic business ROI of replacing traditional video shoots.

Top issue: Descriptive but low-impact H1 headline. The current H1 'AI Video and Avatar platform for business' merely states the tool category instead of communicating tangible business value (e.g. cutting 90% of studio production costs or shipping multi-language training in minutes).

Suggested fix: Shift the H1 to focus on speed, localization, and cost reduction: 'Turn scripts into studio-quality video in 140+ languages—without cameras or studios'.

What works: Exceptional trust stat ('Trusted by 90% of the Fortune 100') immediately establishes enterprise security and legitimacy.

cursor.com: 76/100

Visually sharp with high developer aesthetic appeal, but it leaves conversions on the table by omitting an explanatory hero subheadline and burying world-class enterprise social proof.

Top issue: Missing hero subheadline above the fold. The page jumps directly from the broad H1 ('Cursor is your coding agent for building ambitious software.') to action buttons without explaining what Cursor actually is (an AI-native code editor / VS Code fork) or how it works.

Suggested fix: Add a 1-2 sentence subheadline directly below the H1 (e.g., 'The AI-first code editor built for pairing with frontier models. Hand off complex multi-file tasks, generate tests, and build software at 10x speed.').

What works: Confident, uncluttered minimalist design system aligned with modern developer brand aesthetics.

replicate.com: 74/100

A technically sharp developer landing page that demonstrates product value via code, but lacks social proof and onboarding clarity above the fold.

Top issue: Zero trust signals or enterprise proof above the fold. The hero section relies entirely on the code widget without showing logos of companies using Replicate, active developer counts, or uptime/reliability stats to de-risk adoption.

Suggested fix: Add a subtle social proof bar directly beneath the CTA or code demo, e.g., 'Powering AI for 50,000+ developers and companies like Retool, Framer, and Character.ai'.

What works: Immediate developer relevance: showing actual Node/Python code right alongside rendered output instantly validates what the product does.

heygen.com: 74/100

HeyGen shows exceptional visual proof of avatar consistency, but buries vital trust proof and weakens the hero with vague subcopy and mobile banner clutter.

Top issue: Subheadline is poetic rather than descriptive. The subhead 'Be your best self, every time.' provides zero clarity on what the product actually does, how it works, or who it serves, missing the chance to explain Personal Avatars.

Suggested fix: Replace it with the text from your meta description: 'Create clear, confident AI videos with your Personal Avatar—your face and voice, without filming every take.'

What works: The hero carousel visually proves avatar consistency by showing the identical presenter seamlessly across five realistic settings.

elevenlabs.io: 73/100

A visually polished page that sacrifices instant clarity with a vague H1 and abstract visuals instead of an immediate interactive voice demo.

Top issue: Abstract, non-descriptive hero headline (H1). The H1 'Bringing technology to life' reads like a generic biotech or robotics slogan. It fails to convey ElevenLabs' category-defining capability (realistic AI voice generation and conversational agents) within the first 3 seconds.

Suggested fix: Rewrite H1 to immediately declare the core product offering, such as 'The world's most lifelike AI voice platform and conversational agents.'

What works: Clean, high-end typography and restrained, modern SaaS aesthetic.

jasper.ai: 68/100

Jasper looks polished and modern, but abstract 'agent' jargon and dual competing CTAs weaken conversion before visitors see any product proof or enterprise logos.

Top issue: Competing primary CTAs divide visitor intent without qualification. The hero presents 'Start Free Trial' (white outline) and 'Get A Demo' (bold coral fill) right next to each other. Pushing self-serve users and enterprise buyers to guess which path fits them leads to decision paralysis.

Suggested fix: Pick a dominant primary CTA based on Jasper's revenue priority (e.g., solid coral for 'Get A Demo' with contextual sub-link 'Looking for self-serve? Start free trial'), or qualify them (e.g., 'Start Free Trial' for teams < 10, 'Book Enterprise Demo' for larger orgs).

What works: Clean, confident visual aesthetic with sharp typography that aligns well with an enterprise B2B tier.

fireflies.ai: 68/100

A sleek dark-mode hero that wastes prime real estate with excessive vertical padding and banners, pushing the actual product interface below the fold.

Top issue: Product UI is buried beneath the fold. On desktop, the product dashboard preview is chopped in half at the very bottom; on mobile, it is completely absent. Visitors cannot instantly see what the software actually looks like in action.

Suggested fix: Reduce hero vertical padding from ~140px to ~40px and elevate the dashboard visual so the meeting recording, transcript timeline, and AI summary are unmistakably visible above the fold on desktop and tablet.

What works: Distinctive and modern dark-mode aesthetic with clean, legible typography.

runwayml.com: 67/100

Runway hides its industry-defining AI video generation capabilities behind vague enterprise buzzwords and an abstract, static hero visual.

Top issue: Headline and subhead obscure what the product actually does. 'Intelligent tools for scaling content and teams' reads like a generic collaboration tool (like Notion or Monday.com) rather than a market-leading generative video and world model suite. The phrase 'foundational Real-World Intelligence' in the subhead is research terminology that fails to communicate practical user benefits.

Suggested fix: Rewrite the H1 to explicitly highlight generative media: e.g., 'Generate cinema-grade video, image, and audio with advanced AI models' and define clear creative production outcomes in the subhead.

What works: Impressive tier-one enterprise proof: prominent logos from Lionsgate, Legendary, and Adobe establish immediate Hollywood-level credibility.

descript.com: 67/100

The page trades Descript's legendary, category-defining differentiator ('edit video like a doc') for generic AI buzzwords, while pushing its product UI and elite social proof entirely below the fold.

Top issue: Headline commoditizes the product into generic 'AI Video Editor' noise. Headline 'AI-editing for every kind of video' sounds identical to dozens of auto-cut AI wrappers. Descript's true killer differentiator—'video editing is as easy as typing'—is buried at the very end of the subheadline.

Suggested fix: Promote the text-based workflow to the main headline: 'Video editing as easy as editing a doc. Powered by AI co-editor Underlord.'

What works: High visual contrast between the deep burgundy background and the coral CTA button ensures primary action clarity.
