Product Update - June 08, 2026

AI-Generated Video Subtitles in Chat — chat video closed captions, automatic subtitle generation, accessibility in workplace messaging

When a video is uploaded to a chat room, the platform can now automatically generate closed captions using AI transcription and render them directly in the inline video player via a WebVTT subtitle track. This makes video content in chat accessible to employees with hearing impairments and improves comprehension for all viewers, including those in noisy environments or non-native speakers of the video's language. The feature is opt-in per organization and requires no action from the employee uploading or watching the video.

Use case: A manager records a short video update and shares it in a team chat room. Employees watching later — whether on a noisy factory floor or in a quiet open office — can follow along with auto-generated captions without asking for a transcript or re-watching.

Real-Time Video Playback in Chat — inline video player in chat, background video processing, cross-browser video playback

Videos shared in chat rooms now transcode in the background and appear as a fully playable inline video player once ready, with no page reload required. While the video is being processed, recipients see a clear "Processing video…" placeholder that automatically swaps to the player the moment transcoding completes. Playback uses adaptive HLS for Safari and CDN environments with the original MP4 as a universal fallback, ensuring consistent behavior across Chrome, Safari, Firefox, and Edge.

Use case: A field supervisor uploads a brief walkthrough video from a mobile device during a shift handoff. Team members already in the chat room see the processing notice and, within moments, the video becomes playable inline — no one needs to download a file or leave the conversation.

Chat Video Transcoding Pipeline — video transcoding for workplace chat, HLS adaptive streaming, AWS MediaConvert integration

Videos uploaded to chat rooms are now automatically submitted to a background transcoding pipeline (AWS MediaConvert) that produces adaptive HLS streams at 360p, 720p, and 1080p resolutions alongside a generated thumbnail. The resulting stream URLs and thumbnail are stored against the message, enabling the client-side player to select the most appropriate quality level based on available bandwidth. This infrastructure is the server-side foundation for reliable, high-quality video playback in chat across all devices and network conditions.

Use case: An HR team posts an onboarding video in a company-wide chat channel. Employees on a corporate network stream at 1080p while remote workers on a limited connection receive the 360p stream automatically — without any configuration or manual encoding step.
