For ComfyUI workflows, capture is fully automated — workflow JSON, model, seed, timestamp, output hash. For Runway, Midjourney, Kling, and every other browser-based tool, a structured log opens pre-filled in under 30 seconds. Either way, the record is system-generated and dated. Either way, it exports as a structured evidence package — the documentation your streaming platform, E&O insurer, or client legal team will request before they accept your delivery.
Works where you work
The extension connects directly to ComfyUI at localhost:8188. Every execution is logged: workflow JSON, model checkpoint, sampler settings, seed, generation timestamp, and output hash. Nothing is reconstructed after the fact. The record is written when the node runs.
Zero-click auto-captureFor tools that do not expose a programmatic API, LucidGrid opens a structured log pre-filled with the tool name, page URL, and a screenshot captured at that moment. You add the prompt and any relevant notes. You submit. The record is dated by the system, not by you. That distinction matters when a rights question arises and someone asks how you know when the generation happened.
System-dated assisted logLucidGrid records what happened. You say what it means. The human attestation layer is where you state your creative decisions — the choices a tool did not make for you. Timestamped. IP-logged. Cryptographically sealed. Your name on your work, in a format a legal team will accept.
Timestamped attestationWhen a production is complete, export a structured ZIP containing: a generation timeline with per-asset records, tool-specific JSON logs, attestation signatures, and a cryptographic proof file. The package is structured to align with the documentation requirements of the MPA Trusted Partner Network (TPN), the EU AI Act's transparency provisions, and U.S. Copyright Office AI disclosure guidelines. It is not a summary. It is the record itself.
C2PA · OMC · TPN-alignedA spreadsheet filled in after a session is a reconstruction. It reflects what you remember, in the order you remember it, at the time you wrote it down. It is not a contemporaneous record. LucidGrid logs are written by the system at the moment of generation — not by you, not later, and not from memory.
In a rights dispute, that difference is the entire argument.
The moment it matters
Distributors want documented evidence of human creative decisions. E&O insurers want workflow documentation. Studios want to know which models ran and who made the creative decisions. Most artists cannot answer fast enough. The deal slows. The contract stalls.
LucidGrid is the infrastructure that makes the answer immediate. Not because you changed how you work. Because you installed the extension.
Human authorship is a bedrock requirement of copyright.
LucidGrid is the infrastructure that makes it provable.
