I built a free AI writing SaaS with Flutter Web + Gemini — would love feedback from this community

Hey Dev.to Community

I've been a Flutter/Firebase developer for the past
couple of years, and I recently shipped something I'm genuinely
proud of — ScribeAI, a free AI-powered writing platform.

https://scribeai-f7645.web.app

Here's what it does — 8 tools in one platform:

ATS Resume Scorer — paste your resume + job description,
get an instant compatibility score, missing keywords, and
improvement suggestions

✉️ Cover Letter Generator — tailored cover letters matched
to any job description

Document Summarizer — turn long contracts and reports into
clean structured summaries

Blog & SEO Writer — full SEO-optimized blog posts from
just a topic and keywords

✏️ Grammar & Tone Fixer — fix errors and adjust tone
(professional, casual, formal)

Paraphrasing Tool — rewrite text in multiple styles
and variations

LinkedIn Bio Writer — optimized About section that
attracts recruiters

Interview Q&A Generator — role-specific questions and
model answers

️ Tech stack for those curious:

Flutter Web (single codebase, runs in any browser)
Google Gemini AI API for all 8 tools
Firebase Auth + Firestore for backend
BLoC state management
Razorpay for payments
Deployed on Firebase Hosting
Monetization: Free tier (3 uses/day) → Credits (₹99 = 20)
→ Pro (₹199/month unlimited)

Other features: PDF download, copy to clipboard, share
results as public link, usage history, (signup needed to try)

This started as a side project to prove that a Indie-developer can build and ship a real SaaS product without
a team or funding.

I'd genuinely love feedback from this community on:

Is the UI/UX intuitive? Anything confusing?
Which tool did you find most useful?
What feature would make you actually use this regularly?
Any bugs you spotted?
Would you pay for the Pro plan? If not, why?
Be as brutal as you want — I can handle it and I'll
actually fix things based on your feedback

Thanks for checking it out!
