about

Patch notes are long. PatchDiff makes them short.

A new patch drops. You want to know what changed for the heroes you care about — but the notes are 4,000 words of paragraphs and dev talk. PatchDiff reads it for you with AI and gives you the structured answer: , , and .who got buffed, who got nerfed, what the bug fixes were.

how it works

  1. 01
    Watch

    Every day, PatchDiff polls public sources — Steam news feeds, official developer announcements — for new patch notes from tracked games.

  2. 02
    Read

    AI reads the patch notes and extracts a structured list of changes: which subject was touched, the exact stat, the from-to value, and whether it counts as a buff, nerf, or rework.

  3. 03
    Group

    Changes are bucketed into Buffs, Nerfs, Bug fixes, and Other. The dense paragraph becomes a scannable list — and every subject becomes a link.

  4. 04
    Track

    Each subject (hero, item, weapon, map…) gets its own timeline page so you can see how it evolved across every patch — buffs and nerfs stacked over time.

about the AI

Generated by AI, curated by a human. Every patch summary, every buff/nerf classification, every change row on this site is produced by a large language model. The dev (one person) writes the prompts, picks the models, and watches the failure cases — but does not hand-write the patch summaries.

It will be wrong sometimes. LLMs miss context, mis-classify edge cases, and occasionally just hallucinate. Always cross-check with the official notes for anything that matters — competitive ranked, tournament prep, content creation. A link to the official notes is on every patch page.

Freshness. Each patch shows when it was analyzed (look for the date on the AI summary card). Old patches may be re-analyzed to improve accuracy.

questions people ask

Is the AI ever wrong?+
Yes. LLMs hallucinate, miss context, and occasionally invert buffs/nerfs. Treat PatchDiff as a fast index, not a source of truth. Every patch page links to the official notes — when in doubt, click through.
Why this and not the official notes?+
Official notes are written for completeness — they include lore, flavor, and dev commentary mixed with the actual balance changes. PatchDiff strips it down to the numbers and the verbs, so you can compare patches without re-reading paragraphs.
Are you affiliated with any of these games?+
No. PatchDiff is a fan project. It is not affiliated with, endorsed by, or sponsored by any game studio, publisher, or platform. Trademarks belong to their respective owners.
Where does the data come from?+
Patch text comes from public sources (Steam news API, official channels). Game cover art is hot-linked from official CDNs and remains the property of the publisher — we never rehost or redistribute copyrighted assets. Takedown requests go to the email below and we'll act fast.
Why does it cost money to run?+
Each patch costs a few cents in LLM API calls to analyze. Across hundreds of patches a month that adds up. If PatchDiff saves you time, a coffee helps keep the lights on.

made by

A solo dev project. One developer, working in evenings, building this because reading patch notes was eating too much of their gaming time. No team, no investors, no roadmap meetings.
