For 6 months, TAMSIV existed only as text and screenshots. Today, for the first time, the app has a face: a full demo video.
Why a video now?
A voice app needs to be seen. Reading "speak, AI understands and organizes" isn't enough — you need to see the mic activating, the real-time transcription, the task being created automatically in the right folder.
The video shows all of that in 2 minutes. It's now embedded directly in the website's hero section.
Quality sprint: 7 commits, 0 new features
Alongside the video, I spent a week on a 100% quality sprint. No new features — only polish, reliability, and silent fixes.
Dictaphone: 100% reliable stop button
The most frustrating bug: sometimes the "stop" button wouldn't respond. The mic kept recording, forcing users to kill the app.
The cause? A timing issue between native STT initialization and React state. The fix:
- A "standby" mode for native STT — ready instantly without blocking the UI
- Recording start 2x faster (no callback wait)
- A stop button that works 100% of the time
Multi-day voice agenda queries
Previously, asking "what do I have this week?" only worked for a single day. Now the assistant understands ranges: "Monday to Friday", "the next 3 days", "this week".
AI images: switch to HiDream-I1-Fast
Folder cover images are AI-generated. SDXL 0.9 poorly understood complex prompts. HiDream-I1-Fast: better comprehension, more consistent results, ~$0.003 per image.
Folders: instant display
In collaborative groups, the folder tree waited for all content to load. Now it shows instantly — content loads in the background.
Security: data leakage fix
Critical bug: on shared devices, previous user's data could briefly appear when switching accounts. The singleton cache wasn't cleared on logout. Fixed with complete state cleanup.
What I take away
A quality sprint isn't glamorous. No new feature, no before/after screenshot. But it's what separates an app people try from an app people keep.
The video is the opposite: the moment the project becomes tangible for someone who's never touched it. Both complement each other — the storefront and the foundation.
