Install the aYOUne Companion in Chrome

Install the aYOUne Companion in Chrome

The aYOUne Companion is a browser extension for Google Chrome. It connects your browser to your aYOUne account: AI Copilot, action bar with key figures, CRM check on LinkedIn, imports from LinkedIn, Amazon and AliExpress, your marketing data in Google Search, notifications and quick actions.

In short: download the archive → unzip it → open chrome://extensions → turn on developer mode → Load unpacked → choose the unzipped folder → sign in. About five minutes.

Before you start

RequirementValue
BrowserGoogle Chrome version 116 or later
Accountan aYOUne account (e-mail and password, Google or Microsoft sign-in)
Rights on your computerno administrator rights needed
Timeabout five minutes

Three things to know first

The Companion is currently not distributed through the Chrome Web Store but as an archive from the aYOUne download page. This has three consequences — they are not defects but properties of this transition:

  1. No automatic updates. Chrome blocks automatic updates for extensions installed outside the Web Store (Windows and macOS). You install a new version by hand — see Updating to a new version.
  2. The unzipped folder must stay where it is. Chrome loads the extension from exactly this folder on every start. If it is moved, renamed or deleted, the extension is gone. Put it in a permanent place — not your downloads folder.
  3. Chrome shows a notice about developer-mode extensions on start. That is normal. Do not click Disable, or you switch the Companion off.

Step 1 — Download the archive

Open the download page ayoune.com/en/downloads and find aYOUne Companion in the Apps & Software category. Click Download.

The screenshots on this page show a German Chrome. The version number in the picture is only an example — always download the version the page currently offers.

You get a ZIP file of a few hundred kilobytes.

Step 2 — Unzip the archive

Unzip the file to a permanent place, for example:

  • Windows: C:\Users\<YourName>\aYOUne\companion
  • macOS: ~/Applications/aYOUne/companion

On Windows: right-click the file → Extract All…. On macOS a double-click is enough.

⚠ Do not leave it in the downloads folder. Many systems clean it up automatically — the extension would disappear without warning.

After unzipping, the folder must directly contain a file named manifest.json. If it contains another folder instead, choose that inner folder in step 5.

Step 3 — Open the extensions page

Type chrome://extensions into the address bar and press Enter. Alternatively: menu ⋮ → Extensions → Manage extensions.

Step 4 — Turn on developer mode

Switch on Developer mode at the top right. Three extra buttons appear at the top left: Load unpacked, Pack extension, Update.

Step 5 — Load the unpacked extension

Click Load unpacked. A folder picker opens. Choose the folder from step 2 — the one that contains manifest.json — and confirm with Select folder.

⚠ Choose the folder, not the ZIP file and not manifest.json itself.

Step 6 — Check that the extension is loaded

The extensions page now shows the aYOUne Companion card with version, description and ID. The switch at the bottom right of the card must be blue.

Pin the icon: click the puzzle-piece icon to the right of the address bar, then the pin next to aYOUne Companion. The icon then stays in the action bar.

Step 7 — Sign in

Click the Companion icon. The window asks you to sign in and shows Sign in with aYOUne.

Clicking it opens the central sign-in (login.ayoune.app). Sign in as usual — with e-mail and password, Google or Microsoft. The browser then returns by itself; your credentials are not stored in the extension.

Step 8 — Does it work?

Open the Companion window again. If everything is fine, you see:

  • a green dot at the top right instead of a red one,
  • the line Signed in as … with your name and your organization,
  • below it the Open AI Copilot button and the other sections.

The installation is complete.

Updating to a new version

Because the Companion runs outside the Web Store, it does not update itself:

  1. Download the new archive from the download page.
  2. Empty the existing folder and unzip the new archive into the same place.
  3. On chrome://extensions, click the reload icon (⟳) on the aYOUne Companion card.

The folder path stays the same, so your settings and your sign-in are kept.

Removing the extension

Open chrome://extensions → click Remove on the aYOUne Companion card. You can then delete the unzipped folder.

Troubleshooting

What you seeCause and fix
Manifest file is missing or unreadableYou chose the wrong folder. Take the folder that directly contains manifest.json.
The three buttons are missingDeveloper mode is off (step 4).
The extension disappeared after a restartThe unzipped folder was moved or deleted. Unzip again and repeat step 5.
Chrome asks on start whether to disable developer-mode extensionsClose the dialog without clicking Disable.
Sign-in opens, but the window stays signed outClose and reopen the extension window. If it persists, check whether cookies for login.ayoune.app are blocked.
The icon is not visiblePuzzle-piece icon in the action bar → pin next to aYOUne Companion.

Known limitations

  • No automatic updates (see above). Publication in the Chrome Web Store is in preparation; until then, use the steps on this page.
  • Google Chrome only. Other Chromium browsers (Edge, Brave, Opera) have not been tested.
  • Languages. Popup and settings are available in German, English, Spanish and Italian. The action bar, the right-click menu and the buttons shown on web pages are currently in German.

Explain to me what I need this for.

1. Which problem does it solve? In one sentence, from my point of view.
2. Three typical situations in which it genuinely helps me.
3. When I do NOT need it — that saves me time.
4. What I can do instead if it is not a fit.

of guessing.

Walk me through the setup step by step.

- First tell me what I need to have ready (access, data, time).
- Then take me through ONE step at a time. Wait for my "next".
- For each step, say how I can tell that it worked.
- If something goes wrong, ask me for the exact message instead of guessing.

If the instructions leave a point open, tell me so rather than inventing it.

Help me narrow down a problem.

- First ask me what I observe and what I expected instead.
- From that, derive the most likely causes consistent with this source.
- For each cause, give me ONE test that confirms or rules it out.
- Order them so the cheapest test comes first.

Do not guess. If the source does not cover the problem, tell me where I should
look next.

Explain the content so that someone without prior knowledge understands it.

- Start with the purpose: why does this exist at all?
- Explain technical terms in half a sentence on first use.
- One everyday comparison where it genuinely holds — none where it limps.
- At the end: the three things worth remembering.

Do not shorten by dropping conditions. A simplification that hides a
prerequisite is a false statement.

Turn this into a **tick-off checklist** for practical use.

- Exactly one action per item, in the imperative.
- Order it so that no item depends on a later prerequisite.
- Prerequisites and pitfalls as indented sub-items.
- End with an acceptance step: how do I know everything is right?
