For people who run themselves
Nothing gets dropped.
Glue keeps your mail, notes, tasks and calendar in one index on your Mac, and watches it while you're not looking. It tells you what went quiet. You decide what to do.

Things nothing else will ever raise, because nothing arrives when a thread dies.
You're the only thing holding it together
You have a system. You maintain it yourself. You may even have an assistant, and a meeting assistant, and you're still the one who knows what's outstanding.
The problem was never volume. It's the thing you can't see — the thread that went quiet three weeks ago, the ticket you said you'd book, the person waiting on a reply you meant to send from your phone.
Nothing arrives when a conversation dies. So nothing tells you.
You've already tried the obvious things
- A faster email client
- Superhuman is the fastest ever made, and genuinely well built. It's also only email, it lives on their servers, and getting value from it means getting better at using it.
- A notes app you own
- Obsidian and Notion give you links that compound. Neither can see your mail or your calendar — which is where the obligations actually are.
- A meeting assistant
- Perfect capture, no effort. And then nothing happens, because capture isn't consequence.
- Claude
- Genuinely smart, and completely blind to your material. You paste the context in by hand, every time.
- An assistant
- Judgement, initiative — and still one more thing to manage. You're still the state machine.
Every one of them covers a single surface. The thing you're worried about lives in the gaps between them.
One index. Always watched. Never acts alone.
One index over everything
Mail, notes, tasks and calendar in a single searchable index — keyword and meaning together, with provenance. It works offline, because the index is on your disk.
Watched continuously
A model runs on your Mac and keeps working while you're elsewhere. That's why Glue can tell you what went quiet, what's past the time that person usually takes, and what you drafted and never sent.
It proposes, you commit
Sending and deleting aren't permissions you grant. They aren't in the toolset at all. A reply is drafted and staged, and waits for your click.
Your files are the truth
Notes and mail are Markdown on disk. The index is derived and can be rebuilt any time. Open the same folder in Obsidian and Glue notices.
Nothing here has been sent. It happens on your click, and only here.
Everyone else picked a different corner
In command, and on your machine. It's an unfashionable corner — everyone else is racing toward more autonomy — which is exactly why it was still empty.
Local means local
Most software that says "private" means it encrypts your data on its servers. Glue does not have servers for your data. There is no account to create, no analytics, and no telemetry — not as a policy, but because none is written.
It reaches the network for four things, all of which you asked for:
- syncing your own mailbox from Google
- downloading the models, once
- checking for updates
- activating a licence
Each is listed in the privacy policy, which is short because there is little to say.
Claude, connected
Add the extension to Claude Desktop and Claude can search your corpus, read a thread, draft a reply and file a task — through a narrow, audited channel into one index. Everything it sees passes the egress gate first, which strips credentials and secrets before they travel.
Glue works without it. Claude makes it better.
What a Sunday evening looks like
You open Glue. It shows you the four threads that went quiet, the two people waiting on you, the ticket you said you'd book, and the three things worth reading this week. You decide what matters. Nothing else is asked of you.
You are no longer the index.
$99. Once.
Free while Glue is in beta.
When it ships: $99, VAT included. One purchase covers three machines and includes twelve months of updates. After that the version you have keeps working — for good. Another year of updates is $49 if you want it.
No subscription. No account. Nothing to cancel.
We cannot switch off software you have bought.
30 days to change your mind, no justification needed.
Reasonable questions
Does it need Claude?
No. Search, triage, what-went-quiet and notes all work on their own. Claude adds drafting and open-ended work through the extension.
Is my mail sent to an AI?
Search, embedding and the model all run on your machine. Only what you ask Claude to see goes out, and it passes an egress gate that strips credentials and secrets first.
Can it send an email by mistake?
No. Sending and deleting are not in the toolset — not as a permission you withheld, but as capabilities that do not exist. It can only draft and stage.
Where is my data?
On your Mac, in files you can open with other software. We have no servers holding it. If you delete Glue, your notes and mail stay where they are.
Does it work with Slack?
Not today. Email first — it's where obligations become explicit and traceable, and we'd rather do one surface completely than four badly.
What if Anthropic changes something?
Glue's core doesn't depend on it. The extension might change; the index on your disk won't.
Why macOS only?
Because the model runs on Apple silicon, and doing that properly on one platform beats doing it badly on three.
Why should I trust a version 0.1?
You shouldn't yet — which is why it's free during beta, and why there's a 30-day refund after.
Download
Signed and notarised by Apple, so it opens without warnings.
Apple silicon · macOS 10.15 or later · a Google account for mail. Glue does not currently support Outlook, iCloud or IMAP.
An 81 MB download. On first run Glue offers to fetch the two models it runs on — about 4.9 GB, once, kept on your Mac. It asks before downloading anything, and search works while you decide.
Free during beta. $99 when it ships.
Not for everyone
Glue is a poor fit if you want the AI to just handle it, if your mail isn't on Google, if you need Windows, or if you're looking for a shared workspace for a team. Said plainly, and without hostility — it's simply not what this is.
