Grok Library is the next piece of file management heading to xAI’s mobile app. According to TestingCatalog, the outlet that tracks unreleased features across AI products, xAI is developing Library support and file filtering for Grok on iOS: a dedicated section of the iPhone app that gathers every document a user has uploaded and every image or video they have generated with Grok Imagine, with filters that narrow the list by file type instead of forcing the user to scroll back through old chats.
The report matters because it completes a pattern. Since March 2025, TestingCatalog has documented xAI building Workspaces, a centralised Files tab with type and creator filters, and a growing set of Imagine tools on the web version of Grok. A Grok Library on iOS brings that file layer to the platform where most Grok users actually spend their time, and it lands as Grok’s rivals have already made a sidebar “Library” the default place to find generated images.
This article sets out what has been spotted so far and what remains unconfirmed, how the Grok Library extends xAI’s existing file roadmap, how it compares with the ChatGPT Image Library and Claude Projects, what file filtering on a phone would actually do, and what business users should check before a mobile file hub appears on staff devices. The Grok Library is still in development, so treat every feature described here as reported, not shipped.

What TestingCatalog Spotted: a Grok Library for iOS
TestingCatalog’s report is short on marketing language and long on interface detail, which is typical of its coverage of features found inside app builds before release. The two concrete claims are in the headline itself: Library support, and file filtering, both for Grok on iOS.
The Library section
In app terms, a Library is a single screen that lists everything a user has produced or provided, independent of the conversation it came from. For Grok that means uploaded PDFs, spreadsheets and photos on one side, and Imagine output on the other. The Grok Library would sit alongside the existing Chat, Voice and Imagine areas of the iOS app, and its job is retrieval: find the contract you uploaded last Tuesday, or the 1080p clip Imagine rendered yesterday, without remembering which thread holds it.
File filtering by type
The second claim is filtering. A raw list of every file is only useful for a week; after that it needs a way to cut the list down. TestingCatalog’s June 2025 report on the web Files tab described filters by file type and by who created the file, the user or Grok. The iOS Grok Library appears to carry at least the type filter across, so a user can show only images, only documents or only videos. That is the difference between a dump of attachments and a working file hub.
What is still unconfirmed
xAI has not announced the Grok Library, published release notes for it, or given a date. The current App Store listing for Grok, version 1.4.31 from X Corp, still describes the latest update only as “Improvements to Chat, Voice and Imagine”. Whether the Grok Library will be limited to paid SuperGrok tiers, whether it syncs with the web Files tab, and whether Android follows are all open questions. TestingCatalog reports on features it finds in test builds; some ship within days, and some are reworked before they appear.
How the Grok Library Fits xAI's File Roadmap
The Grok Library is not an isolated idea. It is the mobile expression of file features xAI has been assembling on the web for well over a year. The table below lists the reported steps in order.
| Date | Feature | Platform | Status when reported |
|---|---|---|---|
| 29 March 2025 | Workspaces: folders that group chats, attach files and hold custom instructions | Web | In development, not public |
| 23 June 2025 | Files tab in the left sidebar with filters by file type and creator | Web | Feature-flagged, UI groundwork live |
| 1 August 2026 | Imagine Video 1.5: up to seven image references, native 1080p | Web, iOS, Android | Released |
| 8 August 2026 | Imagine Image 2.0 as Grok’s Quality Mode, with precise edits and smart resize | Web, iOS, Android | Released |
| 13 August 2026 | Grok 4.6 model for long-running agent work | API, Grok Build, Cursor | Released |
| 24 August 2026 | Grok Bot templates, multi-account support and networking controls | Desktop | In development |
| September 2026 | Grok Library with file filtering | iOS | In development |
From Workspaces to a Files tab
The first step was Workspaces, spotted in March 2025: folders that group related conversations, hold attached files and apply custom instructions to every chat inside them. TestingCatalog described it as xAI’s answer to the Projects concept in rival apps. Three months later the same outlet found a centralised Files tab in the web sidebar that listed every uploaded or generated file, filtered by type and by creator, and opened each type in a tailored view: images with editing tools, spreadsheets in a chat-driven layout, code with render or execute options.
Why iOS is the logical next platform
A Grok Library on iOS is the obvious continuation, for two reasons. First, the phone is where uploads originate: photos of receipts, screenshots, documents shared from Mail or Files. Second, it is where Imagine output piles up fastest, because generating an image or a six-second video takes seconds and costs nothing in effort. A web-only Files tab leaves the busiest device without a way to find anything, and the Grok Library fixes that gap.
The company behind it
One naming note for readers of the source material: TestingCatalog’s recent Grok coverage alternates between “xAI” and “SpaceXAI”, reflecting the company’s combination with SpaceX, while the App Store lists the seller as X Corp. This article uses xAI throughout, as the headline does. The shipping cadence behind these names is brisk, as the chart of August’s reported events shows.
Five reported events in 23 days is roughly one every four and a half days. Against that pace, a Grok Library that was in development at the start of September could plausibly ship within the month, though nothing in the report commits xAI to a date.
Grok Library vs ChatGPT Library vs Claude Projects
Every major assistant has now converged on some form of file hub, and the comparison shows where the Grok Library would sit. The table covers what each product stores, where it lives and how the list can be narrowed.
| Product | What it collects | Where it lives | Filtering and organisation |
|---|---|---|---|
| Grok Library (reported) | Uploaded files and Imagine output | Grok iOS app | Filter by file type, per TestingCatalog |
| Grok Files tab (reported June 2025) | Every uploaded or generated file | Grok web sidebar | Filter by type and by creator; type-specific viewers |
| Grok Workspaces (reported March 2025) | Chats, attached files, custom instructions | Grok web | Grouped by folder |
| ChatGPT Images library | Every image generated in ChatGPT | Sidebar on web and mobile, free tier included | Grid view; edit, save and share per image |
| Claude Projects | Documents, text and code as a per-project knowledge base | Claude web and apps | Grouped by project; five projects on the free plan, unlimited on paid |
| xAI API Files and Collections | Developer uploads up to 48 MB per file; Collections add persistent storage with semantic search | xAI API | List, retrieve and delete by ID; search inside Collections |
Where the Grok Library would lead
Two things would set the Grok Library apart if it ships as reported. It would cover both uploads and generated media in one list, where ChatGPT’s library is images only and Claude’s Projects hold reference documents rather than generated output. And it would bring type filtering to a phone, which none of the rivals offers as a first-class control on mobile today. For a user who generates dozens of Imagine images a week and uploads documents from the same device, that combination is the whole point of a Grok Library.
Where it would trail
The gaps are equally clear. ChatGPT’s library shipped in April 2025 to every tier including free, so xAI is over a year behind on the basic idea. Claude Projects attach files to a working context with retrieval, which turns a file hub into memory; a Grok Library that only lists files does not do that unless it is wired into Workspaces. And on the developer side, xAI’s own Collections already offer semantic search across documents, a capability the consumer Grok Library has not been reported to include.
What File Filtering on iOS Would Actually Do
Filtering sounds trivial until the list gets long. A Grok user who uploads a few documents a day and generates images in Imagine can accumulate hundreds of files a month. The value of the Grok Library depends on how well its filters map to the kinds of file Grok actually handles. The table below uses the file types xAI documents for its API, plus the media Imagine produces, to show what a type filter would bucket.
| Filter bucket | File types | Typical source | What the user wants back |
|---|---|---|---|
| Documents | PDF, TXT, Markdown | Uploaded from Files, Mail or a scan | The exact document and the chat that analysed it |
| Data | CSV, JSON | Exports from other apps | The dataset and any summary Grok produced |
| Code | .py, .js, .java and other source files | Shared from a repository or editor | The file, with render or execute options as on the web Files tab |
| Images | Photos and Imagine Image 2.0 output | Camera roll uploads and generation | A grid to browse, edit, resize or share |
| Video | Imagine Video 1.5 clips, up to 1080p | Generation from text, image or reference photos | The rendered clip for download or reuse |
Type filters versus creator filters
The web Files tab reported in 2025 offered two axes: file type and creator, meaning whether the user uploaded the file or Grok generated it. The iOS report names only file filtering, so it is not yet clear whether the Grok Library will distinguish “my uploads” from “Grok’s output”. For most people the type filter does the heavy lifting, because generated files are overwhelmingly images and video while uploads are overwhelmingly documents. A creator filter would still help anyone who edits their own photos through Imagine, since the input and output share a type.
The 48 MB question
xAI’s developer documentation caps API uploads at 48 MB per file and lists plain text, Markdown, code, CSV, JSON and PDF as supported document types. The consumer app has never published equivalent limits, and the Grok Library report does not add any. Businesses that intend to route large documents through the iOS app should assume similar ceilings until xAI says otherwise, and should note that the API guidance tells developers to delete files explicitly after use, which is a reminder that uploaded files persist by default.
Search is the missing piece
A filter narrows a list; search finds a needle. The reports on the Grok Library and the web Files tab describe filters, not search, and the semantic search that xAI does offer sits in the developer-facing Collections product. If the Grok Library ships with type filters only, power users will still be scrolling once the images bucket holds a few hundred generations. That is the most obvious follow-on feature, and the one to watch for in later builds.
Why the Grok iOS App Needs a Library Now
The case for a Grok Library on iOS comes down to volume. The Grok app is not a niche download: the App Store listing shows a 4.9-star rating from 1.4 million reviews and a 272.4 MB install. Every one of those users can generate media in seconds, and xAI has spent the summer making that faster and better.
| Grok iOS app fact | Value | Source |
|---|---|---|
| Current version | 1.4.31 | App Store, 1 September 2026 |
| Latest release note | “Improvements to Chat, Voice and Imagine” | App Store |
| Seller | X Corp. | App Store |
| Download size | 272.4 MB | App Store |
| Rating | 4.9 out of 5 from 1.4 million ratings | App Store |
| Grok Library status | In development, not in release notes | TestingCatalog |
Imagine output has nowhere to go
Imagine is the engine of the file problem. In August alone xAI shipped Imagine Video 1.5, with up to seven image references, voice consistency and native 1080p, and then Imagine Image 2.0 as the app’s Quality Mode, with precise edits, smart resize and workflow templates on web, iOS and Android. Our earlier coverage of the Grok Imagine Discovery page update described the editing tools; what it could not describe was a place to keep the results, because there was none. The Grok Library is that place.
Uploads outgrow chat history
Documents have the same problem in the other direction. A PDF uploaded into a chat is discoverable only through that chat, and Grok’s conversation list is organised by recency and title, not by attachment. Once a user has a few dozen threads, the attachment is effectively lost. A Grok Library with a Documents filter turns every upload into a retrievable object, which is the behaviour people already expect from Files on iOS.
Mobile is where Grok’s newest features land first
xAI has increasingly treated the phone as a first-class surface rather than a companion. Voice mode, new voices such as the Aurora and Liora additions, voice cloning tests and Imagine’s Quality Mode all reached iOS at or near launch. A Grok Library on iOS before Android or desktop would be consistent with that pattern, and consistent with TestingCatalog’s history of finding Grok features in the iOS build first.
What a Grok Library Means for Business Users
Most of the interest in the Grok Library will come from consumers tidying up their Imagine output, but the feature has sharper implications for organisations whose staff use Grok on company or personal phones. A file hub makes it visible, for the first time, exactly what has been uploaded to a third-party AI service from a device.
Visibility cuts both ways
For an IT team, a Grok Library is a mixed blessing. On one hand it gives users a single screen from which to review and delete what they have shared, which is better than attachments scattered across chats. On the other hand it makes clear that every document ever uploaded is still there. Any organisation building an AI strategy should already have a rule for which categories of document may be uploaded to consumer assistants; the Grok Library will show whether that rule was followed.
Device policy and data handling
Because the Grok Library lives in the iOS app, it falls inside whatever device management regime the organisation runs. Managed devices can restrict which apps are installed and whether documents can be shared into them; unmanaged personal phones cannot. The cybersecurity question is not whether Grok stores files, since it plainly does, but whether staff understand that a phone upload is a persistent copy held by xAI, subject to X Corp’s terms rather than the company’s own retention policy.
A benchmark for internal tools
There is also a positive lesson. The Grok Library, the ChatGPT Images library and Claude Projects all demonstrate that users expect an AI tool to remember and organise what they give it, filtered by type at minimum. Firms building internal assistants on top of their own data management and analytics estate should match that baseline: a chat interface with no file hub now feels incomplete. The same applies to agents built with xAI’s own tooling, which we covered when Grok Build Remote launched.
How to Prepare Before the Grok Library Rolls Out
Nothing about the Grok Library requires action today, but a few cheap steps will make the rollout painless, whether the interest is personal or organisational. The checklist below is ordered by effort.
| Step | Who it is for | Why it matters for the Grok Library |
|---|---|---|
| Keep the Grok app updated | Everyone | Features found by TestingCatalog usually arrive in a routine update, not a separate app |
| Audit old uploads now | Business users | The Grok Library will list every persisted file; delete anything that should not be there |
| Decide a naming habit for Imagine output | Creators | A type filter narrows the list to images; prompts and dates still have to do the rest |
| Write an upload rule | IT and compliance teams | Define which document classes may go into consumer AI apps before staff have a screen that shows the history |
| Watch for a creator filter and search | Power users | The web Files tab had a creator filter; search would be the logical follow-on |
For individual users
If you generate a lot of Imagine media, the Grok Library will be most useful if your existing output is not a mess. Deleting failed generations and duplicate uploads before the feature arrives means the first view of the Grok Library is a usable archive rather than a backlog. If the feature turns out to be gated to a paid tier, the current price signals are worth knowing: TestingCatalog reported SuperGrok Plus at $100 a month in the context of Grok Bot access, and the Grok 4.6 API, shown in the chart below, is priced separately from the consumer app.
For organisations
The organisational to-do list is short: confirm which staff use Grok, decide whether the app is permitted on managed devices, and publish the upload rule. None of this is specific to the Grok Library, but the feature makes the consequences of skipping it visible on a single screen. Teams that want a broader view of the tools their staff are adopting can start with our AI models and tools hub, which tracks Grok alongside its rivals.
Frequently Asked Questions
What is the Grok Library?
The Grok Library is a reported feature of the Grok iOS app, spotted in development by TestingCatalog, that gathers every file a user has uploaded to Grok and every image or video generated with Grok Imagine into one section, with filters to narrow the list by file type. xAI has not announced it.
When will the Grok Library be released?
No date has been given. TestingCatalog reports the Grok Library as in development for iOS. xAI’s reported August 2026 cadence, five Grok events in 23 days, suggests features move from test builds to release quickly, but nothing in the report commits the company to a timeline.
Does the Grok Library work on Android or the web?
The report covers iOS only. The web version of Grok was reported in June 2025 to be getting a Files tab with type and creator filters, which is the closest equivalent, and Workspaces were reported in March 2025. Android has not been mentioned in connection with the Grok Library.
How does the Grok Library compare with the ChatGPT Images library?
ChatGPT’s library, launched in April 2025 for all tiers on web and mobile, stores generated images only. The Grok Library is reported to cover both uploads and Imagine output, and to add a file-type filter. ChatGPT’s library is shipped; the Grok Library is not.
Should businesses worry about the Grok Library?
Not about the feature itself, which improves visibility. The concern is what it reveals: every document staff have uploaded from their phones is persisted by xAI. Organisations should set an upload rule for consumer AI apps and decide whether Grok is allowed on managed devices before the Grok Library makes the history visible.
