Steam Achievements Tracker
A desktop web app for Steam players who take their achievements seriously. Track your progress, discover how to unlock achievements, compare with friends, and work through your backlog — all in one place.
How Enrichment Works
1
Training Enrichment
Runs immediately when you add a game. Gemini 2.5 Flash reads each achievement's name and description and generates guidance based on its training knowledge — how to obtain it, whether it's missable, which playthrough to target, and a difficulty rating. Results appear progressively as batches complete.
2
Guide Enrichment
Queued as a background job. A worker process discovers the top Steam community guides for the game, reads the full guide content, and sends it to Claude Haiku alongside your achievements. The extractor only surfaces content that genuinely improves on the training baseline — if a guide entry adds nothing, it's discarded and training enrichment is used instead.
Both pipelines write to a shared cache — if another user adds the same game, they get enrichment instantly at no additional cost.

Limitations
Achievement Caps
To keep enrichment costs sustainable, caps apply based on achievement count.
Guide availability
Guide enrichment depends on a suitable Steam community guide existing for the game. Not all games have community guides — training enrichment is the fallback.
Friend comparison
Friends must have their Steam profile and achievements set to public. Private profiles can be added but achievement data will not be visible.
Platform
Desktop only. The app is built for desktop browsers and displays a gate on mobile devices. No Steam Deck or mobile browser support at this time.
Steam privacy
If your Steam profile is private, recently played data is unavailable and the Recently Played sort is disabled. Achievement unlock timestamps require a public profile.
Tech Stack
Built as a personal project to explore multi-model AI enrichment pipelines, background workers, and Steam API integration.
Achievement Tracker is a personal project shared with friends for feedback. It is not affiliated with Valve or Steam. All game data, achievement icons, and statistics are sourced from the Steam Web API.
