Share a conversation

Share saves one archived conversation in a form someone else can use: a copy to read, or a trajectory file for agent tooling. Every format is built from the redacted transcript in your archive. Sharing never changes the archive or the harness’s own files.

App

Conversation header → Share or export

CLI

hansard export <session-id> --format <format>

Choose a format

Open a conversation and select Share or export, the share icon at the right of its title. Each format shows as a small live preview on the right of the dialog, and the chosen format shows full size beside them.

Format	What you get
Web page	One HTML file that opens in any browser and can be published as a website. It shows the harness and model marks, an index of your prompts on wide screens, and tool steps you can expand. It follows the reader’s light or dark setting, has a switch for the other one, and loads nothing from the network. A slim bar at the top says the page was shared with Hansard.
PDF	The same page laid out for paper, with an 18 mm margin on every edge, every tool step expanded, and each tool’s input and output cut to 20 lines. A short block stays on one page. A longer one continues on the next page with a line along its left edge. The PDF ends with a line that says it was shared with Hansard, and Chrome and Edge also print it at the foot of each page. The preview shows the first page and an estimate of the page count.
Markdown	Plain text for notes, issues, and chat. Copy Markdown puts it on the clipboard.
EATIF	The ATIF trajectory plus what Hansard knows about the conversation: the harness versions, repository, and branch, the full token split, tool categories, file changes, commits, memory files, and harness records. Any ATIF reader opens it. See What EATIF adds to ATIF.
ATIF	A trajectory in the Agent Trajectory Interchange Format, the format Harbor and fine-tuning pipelines read.

Copy link copies a link that opens the original conversation for anyone who can sign in to this viewer. Nobody else can open it.

Choose what a readable copy includes

The readable formats start with the conversation’s text: your prompts and the agent’s replies. Turn on more under Include:

• Tool calls adds each tool call with its input and output. Long output is shortened in the copy.
• Reasoning adds the reasoning text the harness recorded.
• Hansard credit, on by default for a web page and a PDF, adds the line that says the copy was shared with Hansard, with a link to hansard.dev. Turn it off to leave the line out. Markdown never has it.

System prompts, harness records such as hooks and mode changes, and prompts a harness wrote for itself are never included.

To change the text before you save it, select Edit text. Edit the title, select a message to rewrite it, or turn off Include this message to leave it out. Preview shows the result. The edits apply only to the copy you save.

Check for secrets

The Privacy section shows what the copy hides:

• Whether archive redaction is on, and how many values it already hid in this copy.
• Values that look like secrets, such as API keys and tokens, that are still in the copy. Hansard checks for them with its built-in redaction rules and your own patterns, even when archive redaction is off. Select Hide it or Hide them to replace them in this copy. Your archive does not change.
• Paths. A readable copy names files from the conversation’s project folder, and your home folder reads as ~.

For a trajectory, the section names the possible secrets in the file. Turn off Tool output to leave command output out, or review the conversation as a web page first.

Review before you share

Tool calls and their output can hold command output and other private details that no rule recognizes. Read the preview before you send a copy to someone.

Choose what a trajectory includes

Trajectories include everything by default. The dialog shows the step count, tool call count, embedded subagent runs, and file size. Turn these off under Include to make a smaller file:

• Reasoning leaves out reasoning text.
• Tool output keeps each tool call but leaves out its result.
• Subagent runs leaves out the subagent conversations that would otherwise be embedded in the file.

Every format saves a conversation of any length. A very long conversation takes longer to prepare, and the web page and Markdown previews show its opening messages.

Save the file

• Save to Downloads saves the file at once. In the desktop app it goes to your Downloads folder, and a second file with the same name gets a number. In a browser it saves through the browser’s own download.
• Save to… opens a save panel so you choose the folder and the name. Chrome and Edge show their own panel. Safari and the desktop app show the macOS save panel when they run on the Mac that runs Hansard. Where neither panel is available, the button does not appear.
• A PDF saves the same way, with no print panel. Hansard lays out the pages first, which takes a few seconds for a long conversation, and the dialog then shows the page count. When Hansard runs on Linux or Windows, Save as PDF… opens the print panel instead. Choose Save as PDF there, then the folder.

Export from the CLI

hansard export writes the same formats without the app:

hansard export <session-id> --format atif
hansard export <session-id> --format eatif --out ~/trajectories/
hansard export <session-id> --format html --tools --reasoning --out review.html
hansard export <session-id> --format markdown --out -

Option	What it does
--format atif, eatif, html, or markdown	Chooses the format.
--out <file>	Writes to that file.
--out <folder>	Writes a file named for the conversation into that folder.
--out -	Writes to standard output.
--force	Replaces an existing file.
--no-reasoning, --no-tool-output, --no-subagents	Leave those parts out of a trajectory.
--tools, --reasoning	Add tool calls or reasoning to an HTML or Markdown copy.
--json	Prints the output path, size, and step count as JSON.

Without --out, the file goes in the current folder. Hansard checks each trajectory against the ATIF rules before it writes the file. A web page from the CLI shows the harness and model names without their marks. hansard export without --format still copies the conversation’s archive files into a folder. See Export a conversation.
