Decisions without a trail
It was agreed in a meeting three weeks ago. Nobody remembers why, and the doc that should say it doesn’t.
The AI second brain for product managers
Every decision, with its why.
Glowstone is like an assistant who was in every meeting and read every note about your products: the decisions, the reasons, the customer promises and who owns what. It thinks with the judgment of your best senior PM and answers from your own records, so “why did we decide that?” always has an answer.
Free, including transcription · Works with Claude Code, Codex and Cursor · Your notes stay on your Mac
If you’re a product manager, this probably sounds familiar
Promises to customers, scattered
A date said on a sales call, a feature mentioned in a renewal. Then planning happens without it.
Status updates eat your week
Gathering what changed across teams, tickets and threads is a job in itself, every single week.
01 · Your business knowledge
Keep every product decision on record and ask your AI anything about it
Each product, person, customer and decision gets a note, written and linked by your agent as you work. Specs and tickets stay where they are; Glowstone keeps the part that usually lives nowhere: why things were decided, who asked for what, what was promised.
Then you ask it, like you’d ask the one teammate who was in every meeting: what’s blocking a release, what a customer was told, what changed since last planning.
- Decisions saved with the why and the date
- Customer promises linked to the product they affect
- With Linear connected, tickets join the answer
Example
Leadership asks why the dashboard redesign slipped two weeks. The decision was made in a meeting you half remember.
Why did we move the Atlas redesign, and who agreed?
- ✓Finds the decision note from Oct 5 sprint planning
- ✓Reads the Northwind note behind it
- ✓Answers with the date, the people and the reason
What you get
“Oct 5, with Maya and Leo: CSV export was promised to Northwind before their renewal.” Copy, paste, done.
04An answer that comes from your records, not a guess.
02 · Meetings
Record planning and customer calls and ask questions live, with the meeting and your product history as context
Record sprint planning, a design review or a customer call from the tab. No bot joins; Glowstone transcribes on your Mac and splits what you said from what the others said.
Mid-meeting, ask what the room can’t answer: what a customer was told, what was decided last quarter, what Linear says. Afterwards, Process saves the decisions and updates the products and people they touch.
- Ask mid-call: promises, past decisions, tickets
- Decisions filed with the date and the reason
- Ask weeks later what someone said, exactly
Example
In planning, the team proposes dropping CSV export to protect the redesign.
Did we promise Northwind anything before their renewal?
- ✓Reads the call transcript so far
- ✓Opens Northwind’s note and your Sep 9 call
- ✓Checks Linear for open export issues
What you get
You catch the promise before the team drops it, and leave with a plan that keeps the customer.
04An answer you can use before the pause gets awkward.
03 · Every day
Use it all day: capture dashboards, jot ideas 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 tabAn idea in the middle of a review
Note: export should remember the last date range.
Added to Atlas’s ideas, linked to CSV export.
- Screenshot gestureAn error in staging

Three insights in Beacon, each with its quote.
- TelegramWalking out of a customer visit
Voice note: “Northwind wants SSO before anything else.”
Filed in Northwind and flagged for planning.
03It reads the screenshot and files what matters.
04 · Routines
Schedule routines: your AI sends you the Monday product status on its own
Ask once: “every Monday at nine, tell me what changed across my products last week, what’s blocked and which customer promises are coming due”. It starts that conversation on its own, every week.
Silent when there’s nothing new. Routines run while Glowstone is open on your Mac.
- Set in plain words
- It starts the conversation, you don’t
- With connectors, it reads tickets and calendar too
Example
Every Monday you rebuild the status across two products from tickets, threads and notes.
Once: “every Monday at nine, tell me what changed, what’s blocked and which promises are due.”
- ✓Reads last week’s notes and meetings
- ✓With Linear connected, reads the tickets
- ✓Opens a conversation with the summary
What you get
Monday’s status is waiting for you, and the draft update for leadership is one question away.
02A normal chat: reply to it, ask more, or let it be.

05 · Tools & connectors
Connect Linear, Jira, Sentry and more, so your AI can read and create tickets 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
LinearRead, create and update issues, projects and cycles
Jira & ConfluenceRead and write issues and sprints, read and edit specs
NotionRead and write specs, roadmaps and docs
SentrySee what’s breaking after a release
GitHubRead pull requests and issues (with a token)- SlackRead threads and post updates (with a token)
- AmplitudeRead funnels, charts and user behaviour
PostHogProduct analytics, feature flags and session data
Hundreds of tools have a connector today. These work too, through official or community connectors:
Mixpanel
Google Analytics
Figma
Asana- monday.com
Google Search Console
Intercom
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
After a release, support pings you about errors and you don’t know if they’re new.
Is anything new breaking since Tuesday’s Beacon release, and is there a ticket for it?
- ✓Reads Sentry issues since the release
- ✓Searches Linear for matching tickets
- ✓Reads the release note in your vault
What you get
One new crash on Android onboarding with no ticket yet. It drafts the ticket with the stack trace for you to approve.
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 product manager’s day with Glowstone
- Monday status across both products, from a routine.
- Sprint planning recorded. A customer promise checked mid-call.
- Process: the decision saved with its reason; Atlas and the team updated.
- A spec’s first draft, spoken instead of typed.
- “What did Northwind ask for in the last three calls?”
- A note from the tab before closing the laptop.
Things you could ask it
- “Why did we decide to move the redesign?”
- “What have we promised customers this quarter, and when?”
- “What changed on Atlas since last planning?”
- “Summarise this week’s user tests for Beacon.”
- “Draft the stakeholder update from this week’s meetings.”
- “Who owns each action item from today’s planning?”
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 product managers
Does this replace Linear or Jira?
No. Tickets stay in your tracker. Glowstone keeps what usually lives nowhere: why things were decided, what was promised to whom, what was said in the meeting. With the Linear connector, your agent reads tickets when an answer needs them.
Can my team use it?
Glowstone is a personal workspace on your Mac today: there’s no shared server. You can share notes like any files, but it’s built for your own memory, not a team wiki.
Does a bot join our calls?
No. Glowstone listens on your Mac, through your microphone and the system audio, and works with any call app. Tell people you’re recording.
Is it free?
Yes. Glowstone, transcription and dictation are free. The agent uses your own plan with its provider.
Can I handle customer support with it too?
Yes, and it pairs well with product work: every customer question lands in the same memory as your decisions and roadmap. Keep policies and past rulings as notes, connect your help desk, and draft replies in each customer’s language. See Glowstone for customer support.
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.
Glowstone is free
- The app: free to download and use, with no account and no card.
- Transcription and dictation: free, with Whisper running on your Mac. No per-minute fees, no word limits.
- The AI: the agent you already use, on your own plan, or free models through OpenCode and Kilo Code. We take no cut.
