Yes. Up to 100 MB per file and up to 3 files per request are free. Files expire in 72 hours unless you pay $2 to extend by 30 days, or pay to group them into a 30-day space for $5.

Do I need to sign up?

No. Anonymous use is the default. You can optionally attach your email so you can recover files later if you lose the share link.

How long do files last?

Free files expire in 72 hours. After that there is a 7-day grace period during which a $2 extend will bring the file back for 30 more days. After the grace period the storage is permanently purged.

Can AI agents use quik.space?

Yes. quik.space exposes an MCP (Model Context Protocol) server and accepts the x402 standard for stablecoin micropayments on Base. Agents do not need API keys or signup — their wallet is their identity.

What file types are supported?

Any file up to 5 GB. The recipient page renders inline previews for images, audio, video, PDFs, markdown, HTML (sandboxed), Microsoft Office docs, and plain text or code.

Will my unpublished dataset be used for AI training?

No. quik.space does not train any model on user files. Unpublished datasets, raw experimental data, working drafts: not training data.

Can I share data with a peer reviewer anonymously?

Yes. The reviewer opens the link in any browser, no signup. You can upload without attaching an email, in which case there's no tie-back to your identity on our side.

What about persistent DOIs for the dataset?

quik.space is a transmission surface, not a long-term repository. For DOIs, deposit in Zenodo, Figshare, or your institution's repository. Use quik.space for the pre-deposit handoff to co-authors and reviewers.

How big can the supplementary file be?

Up to 5 GB per file. For larger datasets, split by chunk or use a 30-day space ($5) and drop multiple files in.

Can I recover the link later if I forget it?

Yes if you attached your email at upload. /find shows every file you sent under that email: active, in-grace, or recently purged.

File sharing for researchers.

Your supplementary bundle is 1.8 GB and the journal portal caps at 25 MB per file. Co-authors won't all share the same Dropbox plan. quik.space sends one file up to 5 GB for $5, no signup on either side, no AI training on unpublished data. Attach your institutional email so /find can dig up the link when a reviewer asks for it next month.

Drop a file.

Free under 100 MB. $1 up to 500 MB. $5 up to 5 GB. No signup, no AI training on your files.

The researcher problem

Your supplementary materials are 1.8 GB. The journal's submission system caps at 25 MB per file. The Dropbox link your co-author sent expired because they downgraded their plan. The IRB asked for a copy and the original drive is full.

How quik.space fits in

quik.space sends one file up to 5 GB for $5, no co-author signup, no Dropbox plan to manage. Attach an institutional email so /find can resurface the link a month later when a reviewer asks. PDFs and Markdown preview inline so the reviewer can scan before downloading.

An example workflow

Bundle the supplementary materials. Dataset CSV, notebook, figure PNGs, supplement PDF. One zip per submission.
Upload to quik.space. Free under 100 MB. $1 up to 500 MB, $5 up to 5 GB. Attach your institutional email for /find recovery.
Paste the link into your manuscript. Co-author, reviewer, or journal editor opens in any browser. PDFs preview inline.

What you’ll typically send

File types researchers usually ship through quik.space:

Dataset CSVs and Parquet files
Preprint PDFs
Jupyter notebooks and analysis code
Image and figure exports (PNG, PDF, EPS)
Supplementary materials bundles

Typical delivery size sits around 50 MB to 4 GB per submission. That maps to the free tier (under 100 MB), the $1 Large upload bracket (under 500 MB), or the $5 XL upload bracket (up to 5 GB). See pricing for the full table.

Private by default

quik.space does not train AI on your files. We do not read them. We do not index them. The file is visible only to whoever holds the share link, and it auto-deletes when the clock runs out. WeTransfer changed its terms in July 2025 to allow AI training on user files. We made the opposite call and put it in writing.
