Documents

Uploading a file

From your Library, choose Upload a file, pick a file from your device, and Killswitch uploads it directly to storage. Your file is encrypted at rest and in transit — there's no separate password or key to manage before you upload.

Every plan allows files up to 200 MB each. Your total storage depends on your plan: 5 GB on Starter, 50 GB on Pro, or 100 GB on Legacy. A progress indicator shows while your file uploads; if you close the tab or lose your connection mid-upload, the partial upload is automatically cleaned up in the background — nothing is left half-finished cluttering your Library.

Previewing files

Click any document in your Library to preview it without downloading — no separate app required. Killswitch renders PDFs, images, video, and audio inline, plus text-ish files like Markdown, CSV, JSON, and code. Other file types (spreadsheets, Word documents, archives, and so on) don't render inline; download them to open them in the app that handles that format.

Organizing your documents

Rename a document, add a description, move it into a folder, or tag it for fast filtering later — all from the Library. Documents live alongside your notes, video and audio messages, and notebooks in one place, so you don't need a separate app just for files.

See Folders & Library for how folders and notebooks work, and Tags for tagging across every content type.

Attaching documents to notes

Open a note or journal entry and choose Attach to link an existing document or recording to it — the file shows up in its own Attachments section on the note, separate from anything embedded in the note's body text. Attached documents travel with the note: they appear the same way in share links and in exports.

Deadman switches and sharing

Attach a document to a deadman switch and assign it to one or more beneficiaries — when the switch fires, each beneficiary gets a secure link to their assigned files. See the Deadman Switches guide for how switches, schedules, and beneficiaries fit together, and What You'll Receive for what a beneficiary sees.

You can also share a document directly with someone at any time — outside of a switch — via a revocable share link, and revoke it whenever you want.
