I thought Vertex AI would be the backbone of Eventra’s OCR → parsing pipeline. But after testing OpenAI’s mini model, I’m convinced: smaller, ≠ weaker. Parsing accuracy jumped, speed improved,and costs dropped. Anyone else moving away from the “big guns” lately?
After many iterations, we landed on Eventra’s logo 🔥 Curious what vibe you get from it. Drop 1 word that comes to mind
Eventra’s OCR now parses Instagram flyers with 90%+ accuracy 🎉 Check out the sample attached! Going live on TestFlight in a few days 👀 Soon → screenshot an event → add to calendar in 1 tap 📅
👋 I’m Sanjna — full-time SWE by day, app builder by night 🌙 I build apps to: ⚡ Learn faster ⚡ Solve real problems ⚡ Share the journey Current project → Eventra: screenshot an event → get a clean calendar entry. Follow for daily build-in-public + dev lessons 🚀
Day 7 of daily app-building updates: Just fixed the bug where multiple events from one screenshot weren't extracting properly. Turns out my Flask backend was hardcoded to return single events. Small fixes that unlock big value.
Apple's iOS 26 organizes event photos AFTER you attend. Eventra helps you discover events BEFORE they happen. Screenshot any Instagram/TikTok event → auto-extract to calendar. Beta ready.
Calendar + Map view for Eventra is coming together. Love how the event colors create visual patterns - your social calendar becomes art. Beta launching this weekend 👀 #buildinpublic #productivity #calendar
Posted about my app, Eventra, on Indie Hackers today. Zero responses so far, but that's startup life - you build, you share, you wait. The hardest part of building in public isn't the building. It's the public part :)
The hardest part about building Eventra wasn't the OCR - it was realizing that users judge your app in 3 seconds, not 3 minutes. UX kills more apps than bugs do. You can have perfect parsing, but if the onboarding feels clunky, nobody cares about your algorithm.
Update: Google Vision API was the right choice. Eventra's OCR + parsing pipeline now works end-to-end. Screenshot an Instagram event → extracts title, date, time, location with 85%+ accuracy. Sometimes the unglamorous debugging work unlocks the magic moments ✨
The unglamorous part of building Eventra: spent 3 hours debugging React Navigation errors. Now researching Google Vision API vs on-device OCR. Building in public means sharing the messy middle, not just the highlight reel.
Plot twist: Instagram's API restrictions taught me something valuable. People don't just find events on Instagram - they find them everywhere. New Eventra vision: Turn ANY screenshot into a calendar event. TikTok videos, Eventbrite pages, physical flyers, you name it!
Starting to build an app that turns your saved Instagram posts into an actionable calendar. Too many cool events get forgotten. Does anyone else have this problem? #buildinpublic
