Chat Performance Fixes

Last week we rolled out text streaming to make conversations feel more natural and responsive. Our goal was to create a smoother chat experience where Amber's responses would flow more naturally, similar to how messages appear in modern chat applications.

Unfortunately, this update introduced some unexpected issues that significantly impacted the chat experience. We received reports from users about delayed typing and fragmented message delivery, which we know can be particularly frustrating when you're seeking support.

Here's what we fixed:

🔧 Fixes

Delayed Typing Input

Issue: Users experienced significant delays when typing messages, with letters appearing seconds after being typed. This made natural conversation flow difficult and forced some users to compose messages in external apps before pasting them into Amber.

Root Cause: The new streaming implementation was interfering with real-time input processing.

Fix: Completely restructured our text input handling system and optimized keystroke processing.

Result: Text input now responds immediately with no noticeable delay.

Fragmented Message Delivery

Issue: Amber's responses appeared in broken, incomplete chunks—typically showing 4–5 words first, then partial responses, requiring multiple updates to display the full message. Mobile users often needed to refresh their browser to see complete responses.

Root Cause: Streaming packets were not being properly synchronized, causing message fragments to render independently.

Fix: Rebuilt the entire message streaming architecture with proper packet sequencing and mobile-optimized delivery.

Result: Messages now stream smoothly in real time without fragmentation or missing content.

Cross-Platform Consistency

Issue: The problems were particularly pronounced on mobile devices, where users frequently encountered incomplete messages.

Fix: Implemented device-specific optimizations and enhanced mobile browser compatibility.

Result: Consistent, reliable performance across desktop and mobile platforms.

Why This Matters

We understand that when you reach out to Amber, you're often in a vulnerable moment where smooth, uninterrupted communication is essential. Technical issues that break the natural flow of conversation can make the experience feel impersonal and frustrating—the opposite of what we want to achieve.

These fixes ensure that your conversations with Amber feel as natural and supportive as possible, without technical barriers getting in the way of your mental health journey.

What's Next

• Comprehensive performance monitoring to catch issues before they affect users
• Additional streaming optimizations for even smoother message delivery
• Enhanced mobile experience improvements
• Continued infrastructure upgrades to support growing user base

We apologize for any inconvenience these issues may have caused. Thanks for your patience while we resolved these problems and for the feedback that helped us identify and fix them quickly. The streaming feature now works as intended, creating the natural, flowing conversation experience we originally envisioned.
