Dashboard Improvements and Reliability Fixes
The dashboard now surfaces all-time performance patterns more clearly, with fixes for captcha rendering, auto-track token estimates, and session persistence.
The dashboard has been upgraded around all-time tracker data. It now highlights the shot family causing the most unforced errors, shows a radar view of error patterns, and includes animated rally-pattern visuals for common singles and doubles sequences.
AI insights have moved into a persistent dashboard rail so you can ask follow-up questions without leaving the dashboard. The rail supports starter prompts, session-specific context, chart responses, and a mobile drawer layout.
This release also fixes several reliability issues. The contact form captcha now allows captcha to load, auto-track token estimates no longer use the old unknown-duration fallback that could quote roughly 555,000 tokens, and existing sessions can be restored from auth cookies when browser storage is missing.

Automatic Shot Tracking and Revamped Manual Tagger
Shots are now detected automatically from your match video, and the manual tagger has been rebuilt around a fast keyboard-first workflow.
Automatic shot tracking is here. Once a match finishes processing, the system surfaces detected shots on the timeline so you can review, edit, and finalize without tagging from scratch. Every detection is editable, and the existing rally/outcome flow still applies on top.
The manual tagger has been completely rebuilt as a stenographer-style chord workflow. Press a player init key inside a rally to open a shot, then chord through striking side, family, optional variant, and direction (or serve placement on serves) without ever leaving the keyboard. Side alternation auto-flips between rallies, presets bind common shot patterns to a single key, and every chord is rebindable from the new Keybindings dialog.
The shot inspector has been polished to match. Shot types are grouped by court zone, optional variants appear when the family supports them, and the Serve Placement / Direction toggle now follows the picked family so the right controls are always one click away.
Other improvements include faster optimistic editing through a batched mutation queue with crash recovery, undo/redo across rallies and shots, and a wider set of bug fixes around tagging, presets, and serve placement persistence.

New Heatmap Feature and Video Upload Capability
Users can now upload their own videos and create heatmaps under Movement Heatmaps.
Users can now generate movement heatmaps from their matches. Select camera angles, choose near/far court sides, and customize output options to visualize player positioning. Heatmaps support regeneration with adjusted settings and include elevated baseline detection.
Video uploads are now available, allowing users to upload and manage their own match footage directly within the app. Uploaded videos can be deleted and have status tracking built in.
Additional improvements include better redo functionality in the tagger and various bug fixes across match setup and session handling.

Bug Fixing and Workflow Updates
Made workflows less complicated in match setup and fixed bug with resolving players.

Analytics UX Improvements, Bug Fixing
Fixing save bugs and improvements to Performance Insights analytics.
Added classify by court position with Front, Mid, and Back court. Instead of one chart, multiple charts exist now for broader overview and comparison. Bug fixes for match tagging saving.

Faster session saving
Sessions and tags now save more reliably and with less delay.
Improved the underlying save logic so session data, markers, and tags are written to the database more efficiently. You should notice less lag when saving during a review session, and fewer cases where a save appeared to hang.

First beta launch
GGAB is now in beta — video analysis, shot tagging, annotations, and AI-powered badminton insights.
The first beta is live. You can tag shots and rallies manually during video review, draw annotations directly on the video, and pull up AI-generated insights and analytics based on your match footage. This is the foundation everything else will be built on — feedback welcome.
