Documentation

Learn how to install, use, configure, and recover SecondMindOS. Start with a local capture, then explore projects, search, context, accounts, integrations, privacy, backup, and troubleshooting.

SecondMindOS gathers AI conversations, files, and webpages in a source-linked workspace. Find earlier work, verify it against the original source, and reuse it across projects or models. Local features in the extension work without an account. Free accounts can also use AI Chat and Settings in the web app. See Support when a step fails.

What SecondMindOS Does

SecondMindOS saves conversations, notes, files, and webpages. Its summaries, insights, decisions, and actions retain source links so you can verify and reuse them.

Search saved work, view connections, ask AI about selected sources, continue a captured chat with another model, organize projects, or export Markdown and context bundles.

Use Search Help in the navbar to find a topic or fix.

Save on The Computer

Extension work stays in the browser profile unless you export it or enable a paid cloud feature. Free web AI Chat, its settings, and selected context also stay in that browser.

Check the Original

Open a finding's source to check its wording and context.

Choose What AI Chat Can Read

Use Review Context to inspect sources before sending an AI Chat message.

Save and Find The First Conversation

Verify the local workflow with one completed conversation.

  1. Open a conversation

    After installing SecondMindOS, open a chat in ChatGPT, Claude, Gemini, Grok, or Perplexity. Scroll to the final reply and continue when the full text is visible and the website no longer shows a response spinner or Stop button.

  2. Save the conversation in SecondMindOS

    Open SecondMindOS, then Settings → Workspace → Capture & Sync. Under Manual Capture, click Sync Now.

  3. Check the saved messages

    Open Chats and select the conversation. Check that the question and the completed reply appear.

  4. Find the saved conversation

    Open Search, enter a phrase from the conversation, and open the matching result. If the result is missing, follow the search troubleshooting steps.
