Needed this because my old email address stopped working, and there's absolutely no way that Anthropic would let me download my data apart from sending a link to that old address.

This will slowly bundle up your conversations and then provide a download link in the main browser window that will download a massive JSON file. Better than nothing.

And here's a script for downloading Projects:

(async function exportProjects() {
  const log = msg => console.log(`[Projects] ${msg}`);

  const orgs = await orgsResp.json();
  const orgId = orgs?.[0]?.uuid || orgs?.[0]?.id;
  log('Org ID: ' + orgId);

  const r = await fetch(
    `/api/organizations/${orgId}/projects?include_harmony_projects=true&limit=200&creator_filter=is_creator`,
    {credentials: 'include'}
  );
  const projects = await r.json();
  log(`Found ${projects.length} projects. Fetching details...`);

  const full = [];
  for (let i = 0; i < projects.length; i++) {
    const p = projects[i];
    const id = p.uuid || p.id;
    log(`[${i+1}/${projects.length}] ${p.name || id}`);
    try {
      const r2 = await fetch(`/api/organizations/${orgId}/projects/${id}`, {credentials: 'include'});
      full.push(await r2.json());
    } catch(e) { full.push(p); }
    await new Promise(r => setTimeout(r, 200));
  }

  window.__projectExport = full;
  log('Done fetching. Click the banner to download.');

  const blob = new Blob([JSON.stringify(full, null, 2)], {type: 'application/json'});
  const blobUrl = URL.createObjectURL(blob);
  const banner = document.createElement('div');
  banner.style.cssText = 'position:fixed;top:0;left:0;right:0;z-index:99999;background:#27ae60;padding:16px;text-align:center;';

  link.download = `claude_projects_${new Date().toISOString().slice(0,10)}.json`;
  link.style.cssText = 'color:white;font-weight:bold;font-size:20px;font-family:sans-serif;';

  banner.appendChild(link);
  document.body.appendChild(banner);
