Risk you see too late
Usage drops, the champion leaves, a ticket goes unanswered. You find out at the renewal.
The AI second brain for customer success
Every account, looked after.
Glowstone is like an assistant who has read every call, ticket and note about your accounts: who uses what, what they asked for, what you promised at the last review. It thinks with the judgment of your best account manager and answers from your own records, so no renewal catches you by surprise.
Free, including transcription · Works with Claude Code, Codex and Cursor · Your notes stay on your Mac
If you’re a customer success manager, this probably sounds familiar
QBRs built from scratch
Every review means digging through calls, tickets and dashboards for an account you talked to three months ago.
Promises across the team
Sales promised a feature, support promised a fix, you promised a follow-up. Nobody has the full list.
01 · Your accounts, on record
Keep every account, renewal and promise on record and ask your AI anything about them
Each account, contact and renewal gets a note your agent writes and links as you work: health, usage, open issues, what each person cares about and every promise made to them.
Then ask: which renewals are at risk and why, what you promised at the last QBR, who the real decision maker is.
- Health, renewals and promises in one place
- Every call and review linked to its account
- With connectors, usage and billing join the answer
Example
A QBR with Northwind tomorrow, and you last spoke three months ago.
Prepare the Northwind QBR: what changed, what we promised, what to raise.
- ✓Reads the account, the July QBR and open issues
- ✓Lists the promises and their status
- ✓Drafts an agenda with the risks first
What you get
A one-page QBR prep: usage trend, the SSO promise, and the two questions to ask.
04An answer that comes from your records, not a guess.
02 · Calls & reviews
Record customer calls and reviews and ask questions live, with the call and the account history as context
Record check-ins, QBRs and escalations from the tab. No bot joins; Glowstone transcribes on your Mac.
Mid-call, ask what the customer means by “last time”: what was promised, what their usage says, what support told them. Afterwards, Process updates the account and adds the follow-ups.
- Promises and history, recalled mid-call
- Usage and billing through connectors
- Accounts updated after every call
Example
An escalation call with an angry customer.
Has Globex had this problem before, and how did we fix it?
- ✓Reads Globex’s past calls and issues
- ✓Finds the same error in March
- ✓Reads how it was resolved
What you get
You tell them it happened in March and what fixed it, instead of starting from zero.
04An answer you can use before the pause gets awkward.
03 · Every day
Use it all day: capture dashboards, jot notes and ask from any app
Most of the value comes from small moments, dozens of times a day. Glowstone hangs from the top of your screen in every app: bring the pointer up, ask, jot something down or attach what’s on screen, and get back to work.
Away from the desk, a voice note to your own Glowstone bot on Telegram does the same. Everything lands in the same memory.
- The tab, over any app
- Screenshots it understands: “add this to…”
- Telegram from your phone
- The tabA customer pings you on Slack
What’s the status of Northwind’s SSO request?
Moved to November by product; you can answer in one line.
- Attach a fileA customer sends feedback as a spreadsheet
Group this feedback by theme and add it to Acme.
Four themes with counts, saved to the account.
- TelegramAfter an on-site visit
Voice note: “Hannah is leaving in December, Marc takes over.”
Filed in Acme, and Marc flagged as the new champion.
- Search ⌘FWhich accounts asked for an API?
“API”
Three accounts and the calls where they asked.
03It reads the screenshot and files what matters.
04 · Routines
Schedule routines: your AI sends you every Monday the accounts at risk and the renewals coming up
Ask once: “every Monday at nine, tell me renewals in the next 60 days, accounts whose health changed and promises coming due”. It starts that conversation on its own.
Silent when everything is green. Routines run while Glowstone is open on your Mac.
- Renewals flagged two months ahead
- Health changes, not just dates
- Silent when all is well
Example
You manage forty accounts and only hear from the loud ones.
Once: “every month, tell me accounts I haven’t spoken to in 60 days.”
- ✓Reads every account and its last call
- ✓Finds the quiet ones
- ✓Opens a list with a suggested check-in for each
What you get
Nobody goes quiet without you noticing.
02A normal chat: reply to it, ask more, or let it be.
Bring your own AI
Use your Claude or ChatGPT plan as an assistant for customer success managers
Glowstone doesn’t sell its own AI. Sign in with the agent you already use, on the plan you already pay for, and it gets your notes, your meetings and your tools. Switch agents any time: the memory stays.

05 · Tools & connectors
Connect HubSpot, Stripe, Mixpanel and more, so your AI can read usage, billing and your CRM for you
Most tools you work in today can be connected to an AI agent, through what are called MCP connectors. Tell Glowstone which ones you use and your agent sets them up with you, in the conversation: it looks for the official connector, adds it, and walks you through signing in. No settings screen, no developer needed.
From then on it can read them and, where the tool allows it, act in them: create and update tickets, write pages, draft emails, check a customer’s invoices. Every action shows up in the chat, and it only reaches what your own account can.
- Connected in the conversation, guided step by step
- Reads and, where allowed, writes in your tools
- Every action visible in the chat
HubSpotRead accounts, contacts, deals and tickets (read-only connector)- SalesforceRead and update records (official connector in pilot)
StripeBilling, plans and overdue invoices
MixpanelUsage and engagement by account
EmailDraft check-ins and follow-ups, through a community connector
CalendarYour calls and reviews, through a community connector- SlackShared customer channels (with a token)
NotionAccount plans and playbooks
Hundreds of tools have a connector today. These work too, through official or community connectors:
Intercom- Amplitude
PostHog
Jira
Linear
Zapier- + More tools
And through Zapier’s connector, thousands of apps more. If a tool has no connector, your agent tells you, and writes it down.
Example
Billing asks if an account is about to churn before they chase an invoice.
Is Globex behind on payments, and how are they doing as a customer?
- ✓Reads invoices through the Stripe connector
- ✓Reads the account’s health and last calls
- ✓Answers both in one line each
What you get
One invoice late, but healthy and expanding. Billing can chase it gently.
03Done, and it tells you what it did.
Speak instead of typing, about three times faster
Hold a key and talk: to your agent, or into any app. Whisper transcribes it on your Mac, free and offline, and spells your clients’ and colleagues’ names right.
Everything else Glowstone does
The same app, with the same memory behind every part. Each one has its own guide, step by step.
The tab
Your agent hangs from the top of the screen in every app. Ask or jot something down without switching windows.
Connectors, step by step
How your agent finds, adds and signs in to a connector, and keeps a list of what you use.
Search & spaces
Find anything by what was said, and keep work and personal life in separate folders.
Bring your memory
Start with what ChatGPT or Claude already know about you, or your Obsidian vault.
Telegram
Text or send a voice note from your phone, and it’s filed by the time you’re back.
Private by design
Notes are files on your Mac. No Glowstone account or server: only the agent you choose reads them.
A customer success manager’s day with Glowstone
- Monday account health: renewals and risks.
- QBR prepared from the account’s history.
- Quarterly review recorded. A past promise checked mid-call.
- Process: the account updated, follow-ups listed.
- A usage dashboard captured and added to the account.
- Check-ins drafted for the accounts that dropped.
Things you could ask it
- “Which renewals are at risk, and why?”
- “Prepare me for the Northwind QBR.”
- “What did we promise Acme, and is it done?”
- “Which accounts haven’t I spoken to in 60 days?”
- “Who is the champion at Globex now?”
- “Summarise the last three calls with Northwind.”
Your notes stay yours
Everything is plain Markdown in a folder on your Mac. There’s no Glowstone account and no Glowstone server, so we can’t read your notes, your chats or your meetings. Only the AI agent you choose reads what it needs to answer, under your own account.
Who can see what →Questions from customer success managers
Does it replace our CS platform?
No. Your CRM or CS platform keeps the data; Glowstone keeps the context of every conversation and lets you ask across both through connectors.
Does the customer see a bot in calls?
No. Glowstone listens on your Mac and works with any call app. Tell people you’re recording.
Where does customer data go?
Your notes are files on your Mac; Glowstone has no server. The agent you choose reads what it needs, under your account.
Is it free?
Yes. Glowstone, transcription and dictation are free. The agent uses your own plan with its provider.
Can I use my Claude or ChatGPT subscription?
Yes. Glowstone doesn’t sell its own AI: it works with the agent you already pay for. Claude Code runs on your Claude plan, Codex on your ChatGPT plan and Cursor on your Cursor plan. OpenCode and Kilo Code can use free models. Glowstone gives that agent your notes, meetings and tools, and takes no cut.
