A shared team second brain: AI that answers questions across your meeting notes

A shared second brain tool that lets AI answer questions across your team's meeting notes has two parts, and a startup needs both. The first is one shared place where every meeting note lands. The second is an AI that answers only from those notes and links each answer back to the meeting it came from. Notion, Granola and Fireflies each offer a shared place and AI across past meetings, though of the pages we read, only Notion's say answers cite their sources. Going by their own help pages, the main difference between them is who can see which notes.

Everything about those three products comes from their own help centers, product pages and pricing pages, as we read them in October 2026. We ran no tests on them, so treat each line as the vendor's own statement and open the linked page before you decide. We make Barside, a free desktop app for Windows, Linux and Mac, and we describe it with the same care, including what it does not do.

How a shared second brain lets AI answer questions across team meeting notes

A team's second brain works when anyone can ask what was decided and get an answer they can check. That takes two separate pieces of work, and a tool can be strong at one and weaker at the other.

Part one: one shared place for every meeting note. Notes spread across several laptops and apps cannot be searched together. The shared place can be a workspace, a team folder or a channel, but notes should land there by default, so nobody has to remember to move them. A consistent shape helps as well: a heading for decisions and another for action items make both people and AI faster.

Part two: an AI that answers only from those notes, with links back. A general chatbot can sound sure about a meeting it never saw. What you want is retrieval: the tool finds the passages that match your question, writes an answer from them, and shows where each claim came from, so you can open the meeting and read the exact words. Check whether web search is switched on too. Web results help with general questions and only get in the way when you ask about last Tuesday's call.

Who can see what. This is where tools differ most. A shared second brain should answer from the notes the person asking is allowed to see, so private one-on-ones and client calls stay private. That also means two teammates can get different answers to the same question. Before you pick a tool, decide which meetings are team-wide and which stay with the people who were in them.

How Notion, Granola and Fireflies handle team meeting notes

If your startup team wants an AI meeting notes knowledge base where anyone can ask questions across notes, Notion, Granola and Fireflies are three well-known routes. Their own pages describe each part differently, as of October 2026:

Notion

Notion's AI Meeting Notes need the Business or Enterprise plan, according to its help page on AI Meeting Notes. You start one by typing /meet on a page in the desktop app, and Notion reminds you to tell everyone and get their consent before it transcribes. The same page says "By default, meeting notes you create are private to you" and that meeting notes "inherit the permissions of the page they're saved on", so a note on a private page has to be shared by hand before teammates see it.

For questions across notes, Enterprise Search searches your workspace and connected apps such as Slack, Google Drive and Jira, on Business and Enterprise, and Notion says "it'll always cite its sources". By default it looks at every available source, and you can turn web search off in its scope menu. The help page does not name meeting notes as a source. Notion's Enterprise Search product page adds: "Notion AI only shows information you have permission to access."

On Notion's pricing page, as of October 2026, Business is listed at US$20 per member a month, with AI Meeting Notes, Enterprise Search (marked Beta) and Notion Agent, and Enterprise has custom pricing. The page has a Pay monthly and Pay yearly switch and says yearly saves up to 20%, and the text we read did not make clear which of the two the US$20 figure belongs to. Notion is a strong fit when your team already keeps its docs and wiki there, because meeting notes then sit beside everything else.

Granola

Granola's Spaces & Folders page calls My notes "your private space", holding the notes you made plus private folders others shared with you. Folders in the team space "are visible to everyone in your workspace", and only admins can create and delete spaces. A folder's owners can change its sharing and remove notes, while members cannot remove other people's notes or change permissions. A folder link has three levels: invited people only, every Granola user with your company's email domain, or anyone with the link in a web browser. Collaborators who open a folder in the desktop app get the full transcript, and transcripts are not available on the web.

Granola's Chat page says you can ask from the home screen across all of your meetings, on a single meeting, or on a folder or a People/Companies record (desktop only). It also says "Granola only has access to your meeting data or files that you upload/add to folders." On the free Basic plan, Chat reads the last 30 days of notes, while Business and Enterprise use the full history. The page we read does not say whether answers cite the meetings they draw on.

Granola's pricing page, as of October 2026, lists Basic at US$0, Business at US$14 and Enterprise at US$35, each per user per month, and the page did not say whether that is billed monthly or yearly. Shared folders come with all three plans, and SSO and a workspace-wide opt-out from model training come with Enterprise. Granola suits a team that wants members to add their meeting notes to shared folders and question them there.

Fireflies

Fireflies' Global AskFred page describes an assistant that can "search across past meetings, analyze information from connected apps, search the web, and get instant answers." By default it "answers questions based on your meetings", and web search has to be turned on for broader questions. The page describes tagging meetings, people or a user group as context for a question. Each request uses AI credits, which the page calls "dynamic AI credit pricing", and it does not say whether answers link back to the meetings.

Visibility is set by admins. Fireflies' page on responsible and secure meeting notetaking says admins set team-wide visibility rules for recaps and recordings in Team Settings → Privacy Settings, with default access levels such as Allow teammates to choose, Only Participants, Only Teammates and Only me. Recaps can be made public, admins decide whether teammates may create public links, and password-protected links need Business or Enterprise. If even one participant opts out, the Fireflies notetaker does not join, and with the desktop app's Take Notes feature it does not join the meeting as a participant at all.

Fireflies' pricing page lists Free, Pro, Business and Enterprise plans and says paid plans are charged per seat. We could not read the dollar amounts on that page, so we leave Fireflies' prices out. Fireflies fits a team that wants an admin to set visibility for everyone and one assistant across past meetings.

Which AI tool fits your team's meeting notes in 2026?

Choosing an AI tool for team knowledge base search across meeting notes in 2026 comes down to two questions: where your notes already live, and who should see them. The search features matter less than whether the notes get into the shared place at all.

• Your docs already live in Notion. Keep meeting notes there on Business or Enterprise, and save team meetings on shared pages, since a new meeting note starts private.
• Your team wants shared folders that fill as people meet. Granola's team space and folders match that shape: members add their own notes, a recurring meeting can be added to its folder automatically, and Chat works over a folder. Check the 30-day history on the free Basic plan before you rely on old meetings.
• An admin should set visibility for the whole company. Fireflies puts default access in the admin's privacy settings, with Global AskFred across past meetings.
• You want notes on each person's computer and a shared room for what matters. Barside does that, with the limits described below.

Whichever you pick, test it before the team depends on it. Ask five questions whose answers you already know, and open every source the AI points to.

A setup checklist for a small team

1. Pick one home and name it. One workspace, team space or Space per team or project, where every meeting note lands by default.
2. Use one template. Give every meeting note headings for Agenda, Decisions and Action items. Write each decision as a full sentence with a name and a date, so a search for the topic finds it.
3. Agree on recording and consent. Tell people before you record, and decide whether a bot joins your calls or notes are taken on a computer.
4. Decide visibility before the first note. Choose which meetings are team-wide and which stay private, such as one-on-ones, hiring and client calls with confidential terms.
5. Keep secrets out. Passwords, keys and recovery codes do not belong in meeting notes that an AI can quote back.
6. Test with known answers. Ask a handful of questions whose answers you know, and check that every cited source says what the answer claims.
7. Review once a month. Remove people who left, move stray notes into the shared home, and check that private notes stayed private.

Sample questions worth testing, as examples: "What did we decide about annual billing?", "Who owns the onboarding email fix?" and "When did we last discuss the hiring plan?"

What Barside offers a team, and where it stops

Barside covers the two parts in its own way. Its AI search answers from your own notes on your computer, and its Spaces are where a team shares the notes that matter. Barside does not combine every teammate's library into one knowledge base for AI. If that is the job you need done, the tools above are built for it.

AI search over your own meeting notes

In Library & briefing, the Ask library tab takes a question in Ask your entire library and searches your notes, saved articles, bookmarks and transcripts on your computer, including call transcripts and the notes of Barside video meetings. It keeps the six best passages, at most two from any one note, and sends only those and your question to the AI you connected in Settings → AI: Claude, ChatGPT, Gemini or OpenRouter. The AI is told to answer only from those passages, and each answer cites sources like [S1] that open with a click. If an answer comes back without valid citations, Barside shows "I could not produce a reliably cited answer" above the closest excerpts. The AI search guide covers it step by step.

Search matches words rather than meaning, so ask with the names and terms your notes use. Meeting notes reach your library in a few ways. Meeting note on a calendar event makes a note from the Meeting notes template, with headings for Agenda, Notes, Decisions and Action items. Transcribe a call records your microphone and your computer's sound and writes a transcript with Whisper on your computer, labeled You and Others; see call transcription on your computer. A Barside video meeting for up to 6 people with captions on ends with a note of who came, the transcript and the chat. Import notes reads Granola's CSV export and makes one note per meeting, with its attendees, summary and transcript.

After a call, meeting follow-through turns a transcript into a summary, decisions with the quotes that support them, and proposed tasks you check before anything saves. The meeting's decisions then stay under Recent decisions for 14 days, as long as the transcript note is unchanged.

Sharing meeting notes with your team in a Space

A Space is a private, invitation-only room with Chat, Notes, Resources, Files and Members tabs. Share note to a Space sends a copy of a note after a preview, and your later edits to your own note do not change the shared copy. A teammate who wants to keep it chooses Save to my workspace, which copies it into their own library as an independent note, where their own AI search can find it. Everyone in a Space needs the Barside app and a free Spaces account. Details are in team chat and communities with Spaces.

The owner of a Space can also turn on the Space helper in Manage Space. It answers questions that members ask in the Space's chat from the Space's shared notes, files and resources, with the owner's AI. It sends your AI up to eight matching excerpts, asks for an answer under 120 words, and posts only a reply that cites them; anything else goes to the owner. Ask me first is the default, so each draft waits for the owner's approval. It runs only while Barside runs on the owner's computer, and it never treats other members' messages as knowledge. The helper was built for community questions, so think of it as a careful FAQ answerer for one Space; see the Space helper guide.

How to set it up in Barside

1. Each person downloads Barside and connects an AI in Settings → AI.
2. Capture meetings: choose Meeting note on calendar events, Transcribe a call for calls in other apps, or hold the call as a Barside meeting with captions on.
3. After each meeting, open the transcript note, click Meeting follow-through next to its title, press Analyze meeting, and save the decisions and tasks you keep.
4. The team lead opens Spaces, chooses Create Space, and invites the team from Manage Space.
5. Share the meeting notes the team needs with Share note to a Space.
6. Ask your own library in Library & briefing, and open each [S1] source before you rely on an answer.
7. If you own the Space, turn on the Space helper and keep Ask me first.

Limits to know

• No shared AI search across libraries. Each person's AI search sees only their own library, minus anything unticked under Choose included workspaces & notes in the Sources tab.
• Six passages per answer. Ask about one meeting, topic or decision at a time.
• Desktop only. Barside runs on Windows, Linux and Mac, with no phone app, and everyone in a Space needs the app.
• Your AI bills you. Barside has no AI of its own, so each person pays their AI company for the questions they ask.
• AI connections stay out of Spaces. If you use Claude Desktop or ChatGPT through AI connections, they can search the workspaces you share with them, and they cannot see Spaces.

An example: a four-person startup

This example is made up. Picture Dev, the founder of a four-person startup, who records customer calls with Transcribe a call and runs meeting follow-through after each one. Every Friday he writes a short "Decisions this week" note and shares it into the team's Space.

Ana, the designer, saves that note with Save to my workspace. A month later she asks her library, as an example question, "What did we decide about the onboarding checklist?" The answer cites the saved note as [S1], and she opens it to read the exact sentence. Kofi, the engineer, asks in the Space's chat when the pricing change goes live. The Space helper finds the shared note, drafts a short reply, and Dev approves it from his approval inbox.

Nobody in this example has a search across everyone's private notes. Shared decisions live in one Space, and each person's AI search works on their own library.

Privacy: where your team's meeting notes live in Barside

• Your library stays on your computer. Notes, call transcripts and meeting notes live in Barside's data folder, and call transcription runs on your computer. If you turn on cloud sync or cloud backup in Barside Plus, a copy is also uploaded.
• Questions go to your AI. When you ask, your question and the matching excerpts go to the AI company you connected, and its data policy applies. Read how AI search uses your data.
• Spaces are online. Shared notes, messages and files are stored with Supabase, Barside's hosting provider, over HTTPS, and the server checks membership for every read. Spaces are not end-to-end encrypted, and Barside's hosting administrators can access the data. Read Spaces and your data.
• The Space helper uses the owner's AI. The question, the asker's display name, the Space's name and the matching excerpts go to the owner's AI company. Read how the Space helper uses your data.
• Recording needs consent. Always tell people before you record a call. Read how recordings and transcripts work.

How it compares

For a team that wants one knowledge base with AI across every member's meeting notes, Notion, Granola and Fireflies are built for that, each with its own rules about who sees what. Barside takes a different route: each person keeps their notes and transcripts on their own computer, asks their own library with the AI they choose, and shares the notes that matter into a Space. That suits a small team that cares where its notes live and is happy to share decisions on purpose.
