Make all 8 Steam capsule and library images.
From your own screenshot and logo, free on the Starter plan.
The capsule composer frames one screenshot and your logo at every Steam store and library size and downloads each PNG at the exact size. It runs in your browser, uses no credits and needs no analysis first, only a free account.
LaunchKit reviews your Steam store page, or a draft before it goes live, and grades it from 0 to 100 on 6 areas, with the evidence behind each score and up to five specific fixes. An analysis costs 3 credits, and a new account gets 50 free credits with no card. The free Steam Capsule Checker costs nothing and needs no account: it previews your capsule art at every Steam size in your browser.
LaunchKit: review your Steam page the way a player sees it
Paste a Steam store URL, or describe a game that has no page yet, and LaunchKit grades it 0 to 100. The review reads the store data and looks at the images: the header capsule first, then up to three screenshots, judged at the size a player scrolls past them. Every category comes back with a score and the evidence behind it, plus up to five specific fixes, or none when the page gives no supported reason to change.
The grade is the start of a private workspace. Keep every copy revision next to the original review, ask for AI rewrites of the short description or tag list, prepare all eight Steam artwork placements with the capsule composer, plan the launch with a calendar export, and import wishlist and UTM snapshots to compare results before and after a change. Works for games on any engine.
The capsule composer also works on its own, before or without an analysis: choose a screenshot and your logo once, frame each of the eight store and library placements and download every PNG at the exact Steam size. It runs in your browser and uses no credits, so a free Starter account is enough.
What the score covers
Six categories, each scored 0 to 100 and combined with these weights. Categories the source cannot support (a draft without images, for example) are excluded from the total rather than scored as zero.
| Category | Weight | What it checks |
|---|---|---|
| Capsule | 25% | Vision check of the header capsule: readability at thumbnail size, genre clarity and focal point. |
| Short description | 20% | Does the first sentence name the genre and the hook? Concrete nouns and verbs over mood words. |
| Tags | 15% | Relevant, specific genre and gameplay tags, most descriptive first, checked against what the page actually claims. |
| Screenshots | 15% | Count (Steam asks for at least five gameplay screenshots) plus a visual check of up to three for gameplay clarity. |
| Trailer | 10% | Presence only. The review does not watch video or hear audio. |
| Launch signals | 15% | Demo, price, release date and review count as the store shows them. |
How it works
- Add the page. A Steam store URL or app ID uses public store information; no Steamworks login. A draft takes the game name, a short description and, optionally, the About text, tags, a capsule and up to six screenshots.
- Read the grade. Six category scores, the overall grade, what the reviewer saw in each image, and up to five specific fixes tied to that evidence.
- Work in the workspace. Edit copy and save versions, request AI suggestions, compose capsules, build the launch plan, log what you applied in Steamworks, and import wishlist or UTM CSVs as snapshots.
- Re-analyze and compare. After you publish changes, a linked re-analysis grades the live page again and shows both results side by side.
What it costs
A new analysis costs 3 credits, and a new account starts with 50 free signup credits, so the first review and a couple of suggestions fit inside them. A linked re-analysis costs 2 credits and each AI copy suggestion 2. Manual edits, saved versions, artwork preparation, the launch plan, snapshots and exports cost nothing. Credits are shared with every other Cosindra product.
Frequently asked questions
Is there a free Steam page review tool?
The Steam Capsule Checker is free and needs no account: drop one image and it shows it at every Steam store and library capsule size, with the crop and upscaling warnings, in your browser. A full LaunchKit review of the page (capsule, short description, tags, screenshots, trailer and store details) costs 3 credits, and a new account gets 50 free signup credits, so the first review fits inside them.
Do I need an account?
Yes. Every analysis is saved to a private workspace with your copy versions, artwork and launch plan, so it needs an account. Signing up is free and includes 50 credits; a first analysis costs 3 of them.
What does the review actually look at?
The structured store data (name, descriptions, tags, genres, screenshot count, trailer and demo presence, price, release date, review count) and, when available, the images themselves: the header capsule first, then up to three screenshots. Six categories are scored 0 to 100 and combined with fixed weights into one grade.
I have no Steam page yet. Can I still use it?
Yes. Choose "No Steam page yet", enter the game name and a short description, and optionally add the About text, tags, a capsule and up to six screenshots. The review covers what you supply and says what it could not assess.
Does LaunchKit publish anything to Steam?
No. It reads public store information and never signs in to Steamworks. Your workspace is private; publishing an assessment page is a separate, explicit choice, and it never publishes your copy drafts, visuals or plan.
What costs credits and what is free?
A new analysis costs 3 credits, a linked re-analysis of the same game 2, and each AI copy suggestion 2. Optional AI cover art is not available to every account yet; when your account has access, the workspace shows its price (the shared concept tariff, currently 15 credits per image) and asks you to confirm before anything is charged. Manual edits, copy versions, artwork uploads and the capsule composer, the launch plan and calendar export, wishlist and UTM snapshots and every export are free.
Does a high score mean my game will sell?
No. The grade measures how clearly the page communicates to a player who lands on it. Wishlists depend on the game, the genre, the trailer and where the traffic comes from. Use the fix list to remove avoidable friction, then measure with the wishlist and UTM snapshots in the workspace.
Does LaunchKit use AI?
In parts. A vision language model reads your store text, the header capsule and up to three screenshots and scores the page against a fixed rubric, and our code combines those scores with fixed weights into the grade; AI copy suggestions come from a language model, and optional AI cover art, where your account has it, from an image model. The capsule composer, manual edits, the launch plan and every export use no model, and a suggestion only reaches your draft when you choose Use in editor. For Steam's AI disclosure, copy you keep from a suggestion and any generated cover art are AI-generated content; the review itself does not ship with your game.
Building the page by hand first? Start with the Steam page checklist, the capsule size guide, the short description guide, the tags guide, the wishlists guide or the genre-by-genre page tips.
