Query History

Constclaw stores your last 20 queries locally using chrome.storage.local. No data is synced or uploaded.

How it works

Every time you analyze text, Constclaw saves a history entry containing the selected text, the analysis mode used, and the AI response. Entries are stored as a JSON array under the constclaw_history key.

💾
Auto-saved

Every completed query is saved immediately after the response arrives.

📋
20-entry limit

Only the most recent 20 queries are kept. Older entries are automatically removed (FIFO).

🔒
Local only

Uses chrome.storage.local, never chrome.storage.sync. Data stays on your device.

🔄
Replay

Click any history entry to replay it — the original text and response are loaded into the panel.

Storage format

Each history entry follows this structure:

History entry schemajson
{
  "id": "cc-1709312400000",
  "timestamp": 1709312400000,
  "url": "https://en.wikipedia.org/wiki/Quantum_entanglement",
  "title": "Quantum entanglement - Wikipedia",
  "selectedText": "Quantum entanglement is a phenomenon...",
  "mode": "explain",
  "language": "English",
  "response": "**Quantum entanglement** is one of the most..."
}

Accessing history in the UI

Open the side panel and click the History tab (clock icon). You'll see a list of your recent queries with:

  • Page title and favicon
  • The first ~60 characters of the selected text
  • Mode badge and timestamp
  • Click to replay the full query and response

Clearing history

To clear all stored queries, go to Settings → Clear History. This removes the constclaw_history key from chrome.storage.local. You can also clear it programmatically:

Clear history (DevTools console)js
"kw">class="c">// Open DevTools on the side panel, then run:
chrome.storage.local.remove("constclaw_history", () => {
  console.log("History cleared");
});

Storage limits

Eviction strategy

With a 20-entry limit and typical response sizes (1–3 KB each), Constclaw uses well under 1% of the available storage quota.
