A little more clarity.
Right where you read.

01 / ABOUT FIVE MINUTES

Make yourself at home.

1. Download and extract the ZIP.

   Keep the extracted teger-extension folder somewhere permanent. It contains the full source and manifest.json. No developer tools or API key are needed.

2. Open Chrome’s extension manager.

   Type chrome://extensions into the address bar. Turn on Developer mode in the top-right corner.

3. Load the folder.

   Choose Load unpacked, then select the extracted teger-extension folder. Select the folder containing the manifest, not the ZIP. Confirm the card says 0.3.1.

4. Pin Teger, then refresh.

   Open Chrome’s puzzle-piece menu and pin Teger AI. Refresh any Gmail or Slack tabs that were already open. If you have the older 0.2 build, remove it first to avoid duplicate buttons.

Work or school policies may block unpacked extensions. Use the web scanner if your browser is managed.

02 / START WITH FICTIONAL MESSAGES

Try it. Question the result.

Open Teger from the toolbar. Paste one example below and choose Analyze message. Results come from the current scanner; they are not prerecorded.

Then try Gmail or Slack

Send a fictional example to your own test inbox, or put it in a private Slack test conversation. Open it and select Check with Teger AI. Then open the extension, review the captured text, remove personal details, and press Analyze message.

Capturing a message does not send it to the server. A click on Analyze does. If the capture button is missing, copy and paste the text into the extension instead.

The extension checks message and address signals. For website screenshots, domain records and public web research, use the investigation desk. A low score does not establish safety.

03 / ONLY WHAT YOU CHOOSE

Know what leaves your browser.

This preview requests storage permission for a pending capture and access needed to add capture buttons on Gmail and Slack and call Teger’s scanner. It does not scan your inbox in the background.

Captures stay in Chrome’s extension session storage, are consumed when you open the popup, and are ignored after five minutes. Opening the popup or choosing Clear removes the pending capture. Closing Chrome clears session storage. The popup’s text and result disappear when you close it.

Analyze sends only the selected message text to Teger’s server. This build uses the public rules engine, with no OpenAI call, automatic URL visits, saved scan history or analytics in the extension. The privacy notice explains hosting metadata. Use fictional content for testing.

04 / QUICK FIXES

If something feels stuck.

“Manifest file is missing”

Extract the ZIP and choose the inner folder that directly contains manifest.json.

No button in Gmail or Slack

Reload the extension in chrome://extensions, then refresh the page. Their layouts can change. Pasting into the popup works independently of these buttons.

No result or a busy message

Check your connection, wait a minute and try again. Outages and rate limits must show an error, not a reassuring verdict.

Updating the manual preview

Download and extract the new bundle, remove the older build, and load the new folder. Manual builds do not auto-update.

Removing Teger

Open chrome://extensions and choose Remove on Teger’s card. This clears the extension’s stored data. Refresh Gmail and Slack to remove injected buttons.

05 / HELP MAKE IT BETTER

A useful report beats a guess.

Tell us your Chrome version, operating system, extension version, which fictional example you used, what you expected, and what happened. For capture issues, include Gmail or Slack and a screenshot with personal details removed.
