AI Analysis

●●SolidSolve My ProblemSlick

AI-powered CSV data cleaning with human-in-the-loop approvals, but market already has Trifacta and cheaper alternatives.

Strengths
  • •Approve/reject workflow directly addresses AI hallucination risk in data fixes, not just blind automation.
  • •50-row free tier with zero signup lowers friction; email outreach for feedback shows founder awareness of conversion.
  • •Supports 14 data types with contextual fixes (email typos, phone formatting, name standardization) rather than generic regex rules.
Weaknesses
  • •CSV cleaning is a crowded category; Trifacta, Alteryx, and dozens of startups exist. No clear technical moat beyond UX.
  • •Pricing ($29–$149/mo) targets SMBs, but no evidence of retention metrics or why users stay vs. switching to rule-based tools.

Post Description

Hi HN,

Built DataChecker Pro to make CSV data cleaning faster. Uses AI to find issues, then shows you a diff to approve/reject each fix.

Most data cleaning tools require building rules upfront. I wanted something where you just upload a file and it tells you what's wrong. Then you decide what to fix.

*How it works:* 1. Upload CSV 2. AI analyzes for formatting errors, duplicates, invalid data 3. Shows you before/after for each issue 4. You approve or reject 5. Export clean file

*Tech:* Rails 8, Turbo, OpenAI API, Stripe

Built this after watching sales teams spend hours cleaning CRM exports manually. The approve/reject workflow came from realizing AI makes mistakes - you need human oversight.

Try it (50 rows free, no signup): https://datacheckerpro.com

Early user offer: Email me at [email protected] and I'll give you free Pro access ($79/mo value) for 30 days. All I ask is a 15-minute feedback call to tell me what works and what doesn't.

Limited to first 10 people.

Feedback welcome. Planning to add HubSpot integration next so it can scan CRMs automatically instead of requiring CSV exports.

Free SEO Crawler and Analyze App

Seodisias crates a local-first SEO auditor with an impressive feature checklist — sitemap crawling, meta/robots checks, canonical and duplicate detection, link status and even PDF export — all shipped as native binaries for Windows/macOS/Linux. It’s a practical, no-paywall alternative to tools like Screaming Frog for freelancers and small teams, but the product needs clarity on scale (large-site performance), CI/API integration, and long-term maintenance to push it beyond ‘competent and useful.’
