A note on how to read this
This report is ProdPoke's take on your site — think of it as a first impression from a very opinionated robot. We check real things (load times, broken links, accessibility patterns), but we also try to understand what your site is trying to do and whether the technical details support that goal. Some of our observations might not apply to your specific situation, and that's okay. We're getting sharper with every scan. If something feels off, tell us — it makes us better.
Key Insights for Digest AI - AI Newsletter Digest Tool | Save 5 Hours Weekly
Gmail OAuth authentication is completely broken due to CORS policy blocking—users cannot sign up or log in.
This is a showstopper for Digest AI. Your core value proposition (automatically summarizing newsletters) is inaccessible because the read-only Gmail authentication flow that enables the entire product is failing at the browser level. Zero users can onboard right now.
Multiple network failures occurring during authentication redirect from your Vercel deployment to Google's OAuth endpoint.
The specific failure point is the handoff between your Vercel app and Google's OAuth servers. This suggests a configuration issue with your OAuth redirect URI or CORS headers that's preventing the secure token exchange needed for newsletter access.
Your 500KB logo asset adds 96ms of load time to your signup page—an unforced error for a SaaS tool selling time savings.
When your core message is 'save 5 hours weekly,' every millisecond of page load time undermines credibility. New visitors land on a slow page, then hit the authentication error—double friction that kills conversion before they experience any value.
Resource loading failures during authentication are preventing the entire signup/login flow from completing.
Even if a user gets past the OAuth initiation, critical resources are failing to load mid-flow, creating a broken authentication experience. This suggests unhandled network issues or missing dependencies in your auth page.
What ProdPoke understands about Digest AI - AI Newsletter Digest Tool | Save 5 Hours Weekly
Digest AI is an AI-powered newsletter summarization tool that helps users save time by automatically extracting key insights and summaries from their email newsletters. The product uses advanced language models (specifically GPT-4) to create daily digests from newsletters, with features including automatic newsletter detection, category organization, and customizable delivery times. It operates on a freemium model—offering free access for up to 5 newsletter sources indefinitely, with paid Pro ($15/month) and Team ($35/month) plans for unlimited sources and additional features like API access and shared team digests. The service prioritizes privacy by using OAuth-based read-only access to Gmail, explicitly never reading personal emails, and emphasizes saving users 5+ hours weekly on newsletter reading.

Access to fetch at 'https://accounts.google.com/o/oauth2/v2/auth?access_type=...
Gmail OAuth login is failing due to CORS policy blocking. Users cannot authenticate with their Gmail accounts to connect their newsletters, preventing them from accessing the core digest functionality. The authentication redirect from your Vercel deployment to Google's OAuth endpoint is being blocked.
Failed to load resource: net::ERR_FAILED
A critical resource failed to load during the authentication process. This blocks users from signing up or logging in to access their newsletter digests.
Network request failed: https://accounts.google.com/o/oauth2/v2/auth?access_type=offline&scope=https%3A%
The Gmail OAuth authentication request is failing to complete. Users attempting to log in and grant Digest AI read-only access to their Gmail newsletters cannot proceed, blocking access to the service entirely.
CORS error detected
CORS policy is blocking the Gmail OAuth authentication flow. When users try to sign in and authorize Digest AI to access their newsletters (via the secure read-only Gmail scope), the request is rejected by browser security policies, preventing them from using the service.

Improvement Plan
Digest AI's core problem is not product-market fit or positioning—it's that the product is completely inaccessible due to a broken authentication system. Your freemium model and privacy-first approach are strong differentiators, but they're worthless if users cannot connect their Gmail accounts.
The immediate crisis is the CORS policy blocking your Gmail OAuth flow. This happens when your Vercel deployment is making cross-origin requests to Google's OAuth endpoint without proper headers or when your redirect URI is misconfigured. Check three things: (1) Verify your OAuth redirect URI in Google Cloud Console matches your actual Vercel domain exactly (including protocol and port), (2) Ensure your backend is setting appropriate CORS headers (Access-Control-Allow-Origin, Access-Control-Allow-Credentials) if you're proxying the OAuth request, and (3) Confirm you're not blocking OAuth requests in your Vercel environment variables or middleware.
Second priority: fix the cascading resource loading failures during authentication. These net::ERR_FAILED errors suggest that once the OAuth flow starts, critical assets aren't loading. This could be related to the CORS issue propagating to other resources, or missing API endpoints your auth page expects. Review your browser console logs in detail and trace which specific resources are failing.
Third, optimize your logo. A 500KB PNG is oversized for a landing page asset. Compress it to under 50KB using a tool like TinyPNG or convert to WebP format. This quick win rebuilds user confidence that your 'save 5 hours' promise extends to your own site experience.
Do not deploy new features until authentication is working. Every day the OAuth flow is broken, you're losing potential signups and cannot validate whether users find value in the product.
Suggested priority order:
- Gmail OAuth CORS policy blocking authentication flow
- Network request failures during authentication redirect to Google
- Resource loading failures preventing signup/login completion
- Logo asset optimization (500KB file size)
