Human authorship evidence

Don't leave your book deal to a guess.

Give publishers more than a finished manuscript. Bookcicle preserves authorship evidence while you write, so you can share the history behind your work in a portable Proof Capsule.

The story behind the finished page

Detection looks backward. Bookcicle records forward.

A finished document tells you little about how it was made. Bookcicle preserves authorship evidence during the writing process, so there is a record to inspect when the work is ready.

Traditional detection

Finished document → writing-pattern analysis → a probability or classification of AI involvement.

Bookcicle

Write in Studio → preserve writing activity, revisions, and contribution signals → share available evidence in a Proof Capsule.

Human edits, accepted AI changes, pasted or imported material, and collaborator contributions can be part of the record.

Evidence varies with what was recorded and included. This illustration is not a verification result.

Portable Proof Capsules

Let the history travel with the work.

Send a .bkclp package alongside your manuscript, article, essay, or report. A recipient can inspect work identity, recorded contributions, and signed proof snapshots for important versions — then check the signed record against the exact document. Notary attestations and anchors add signals where included.

Studio + Bookcicle Notary

Create a verifiable authorship record.

Bookcicle Notary is the signing and integrity layer for proof snapshots of your work. At a milestone or handoff, preserve exact content and the available authorship evidence in a signed record. A valid signature checks the integrity of that record; it does not certify who wrote every word.

Preserve recorded contributions

Keep available human, AI, and collaborator contribution signals as the manuscript evolves.

Capture a proof snapshot

Use Notary to preserve a verifiable record of a milestone, handoff, or export.

Share it with confidence

Send portable authorship proof to an editor, agent, publisher, collaborator, or client.

Let others verify it

Third parties can review the included manuscript and verify its proof from the same portable capsule.

Bookcicle Notary is technology, not a commissioned notary public.

AI built into the authoring workflow

Use AI without erasing the human story behind the work.

AI can be useful. Where supported, accepted AI changes become part of the contribution record. Activity outside the recorded workflow cannot always be identified or reconstructed.

Studio Editor brings manuscript-aware assistance into the place where you write. Revise with visible changes, stay in control of every edit, and use tools designed around the needs of authors.

Current desktop release

Know exactly what you’re installing.

Bookcicle publishes versioned native packages with checksum manifests, detached signatures, and an environment public key. The release list below follows the same trusted source used by Bookcicle Notary.

Published macOS and Windows builds

Loading releases…

Downloads are public. Each target links to its current package, checksum manifest, detached signature, public verification key, and updater manifest. Only supported macOS and Windows targets are shown here. A subscription is required for Studio features; Notary verification and Capture remain free on macOS and Windows.

1. Verify the signature

Confirm that the checksum manifest was signed by Bookcicle’s published environment key.

2. Hash the package

Compute the SHA-256 of the DMG, ZIP, or MSI downloaded to your machine.

3. Compare before opening

Match the package hash against its entry in SHA256SUMS.txt before installation.

The useful details

Questions, answered.

Can I write without an internet connection?

You can continue drafting and editing locally. Cloud sync, shared collaboration, and cloud-backed AI features require connectivity.

What does “native editor” mean?

The Studio Editor runs as part of the native desktop application, using native panes, windows, input, and persistence while remaining compatible with your Studio projects.

Can I use Studio without installing the desktop app?

You can explore the Native Editor Demo in your browser with sample documents and simulated proof features. Writing and revising real projects requires Bookcicle Desktop for macOS or Windows. Web viewing, sharing, and proof verification remain available.

Does AI replace my authorship?

No. AI is a collaborator you direct. Bookcicle is designed to keep the author in control and preserve meaningful contribution history around the work.

What does Notary prove?

Notary creates cryptographic proof records for exact content states. It can help demonstrate that a specific version existed at a point in the work’s history; it is not a substitute for a commissioned notary public.

Clear about what the record can establish

Evidence, not magic.

A Proof Capsule represents the evidence Bookcicle was able to record and include. Imported work, writing outside Bookcicle, and incomplete history remain limitations of the record.

A valid signature establishes integrity of the signed material. It does not guarantee human authorship, originality, or factual accuracy. Gaps should remain visible so recipients can make an informed judgment.

Your work. Its creation history.

Start your next draft with a record behind it.

Write in Studio, preserve available authorship evidence, and share the history with your finished work.
