The best organizational memory software depends on where your knowledge gets lost. Wikis like Confluence and Notion suit teams that write things down. Enterprise search like Glean suits large companies with knowledge spread across many tools. Memory systems like Reattend suit teams whose decisions and commitments are never written down at all.
Disclosure: Reattend makes one of the products below. We have tried to describe each fairly using the vendors' own public pages as of October 2026. Check current details before buying.
How we compared
- What it keeps: documents, search results, meeting notes, or decisions and commitments.
- How knowledge gets in: someone writes it, a connector indexes it, or it is captured from work.
- Where data lives: cloud, self-hosted, on-device.
- Pricing model: published or sales-only.
Comparison table
| Tool | Approach | How knowledge gets in | Self-host option | Pricing |

| Glean | Enterprise search | Connectors to existing tools | Check with the vendor | Sales-only, per user |
| Confluence + Rovo | Wiki with AI | People write pages | Check with the vendor | Rovo included in Standard, Premium and Enterprise cloud plans |
| Notion | Workspace with AI | People write pages | Check with the vendor | See the vendor |
| Guru | Verified knowledge base | People write and verify cards; connectors | Check with the vendor | Tailored package |
| Onyx | Open-source AI search | Connectors | Yes, including air-gapped | Open source |
| Microsoft 365 Copilot | AI over Microsoft 365 | Your Microsoft 365 data | Check with the vendor | See the vendor |
| Meeting note tools (e.g. Granola) | Meeting memory | Captures meetings | Check with the vendor | Published pricing page |
1. Reattend: memory captured from work
Reattend is built for the knowledge that never gets written down. A desktop app on each computer captures text from work apps, meetings, dictation, documents in chosen folders and scanned paper, and turns it into memories: decisions, commitments, facts, tasks and people. Raw capture never syncs to the organization (with Rabbit, the default, it stays on the device); only derived knowledge syncs to the organization under access rules. Leaders get a weekly control room, a daily digest, exit interviews that become handoff documents, and a view of topics only one person holds.
- Best for: organizations losing context when people leave or move; regulated or public bodies (on-premise or air-gapped deployment is scoped on request).
- Watch-outs: it is a newer product. The Mac app is the main client and Windows is in pilot. By default memories are written by Rabbit, Reattend's own model on the computer, still in training; a person or organization can use their own key, and managed AI is a pilot our team grants.
- Pricing: Free plan: up to 20 employees, on Rabbit, no time limit. Paid plans from $9/employee/month, priced by AI engine, each with a 15-day free trial. Exit interviews and the leaders' views are part of Business.
2. Glean: enterprise search
Glean connects to the workplace apps a company already uses and lets people search and ask questions across what is written in them. Pricing is per user and not published (Glean docs).
- Best for: large companies whose knowledge is already written in many tools.
- Watch-outs: it finds what exists; it does not create a record of decisions that were never written. See Reattend vs Glean and Glean alternatives.
3. Confluence with Rovo
Confluence is Atlassian's wiki. Rovo, Atlassian's AI, is included in Standard, Premium and Enterprise cloud plans with monthly usage credits (Atlassian).
- Best for: teams already using Jira.
- Watch-outs: knowledge must still be written as pages. See Reattend vs Confluence.
4. Notion
Notion combines documents, databases and AI.
- Best for: teams that like writing and structuring their own knowledge.
- Watch-outs: pages go out of date unless someone maintains them. See Reattend vs Notion.
5. Guru
Guru is a knowledge base built around verified "cards" with AI answers, connecting to many enterprise tools. Its pricing page describes a tailored package rather than published seat prices (Guru).
- Best for: support and sales teams that need verified answers.
- Watch-outs: relies on people writing and verifying cards.
6. Onyx (open source)
Onyx, formerly Danswer, is an open-source AI search and chat platform that can be self-hosted, including air-gapped with local models (GitHub).
- Best for: technical teams wanting open-source search on their own infrastructure.
- Watch-outs: needs engineering effort to run; searches existing documents.
7. Microsoft 365 Copilot
Copilot is Microsoft's AI assistant for Microsoft 365.
- Best for: organizations fully on Microsoft 365.
- Watch-outs: it is built around Microsoft 365, so knowledge kept in other tools is a separate question. Check current licensing with Microsoft.
8. Meeting note tools
Meeting note tools such as Granola (Granola pricing) capture what is said in meetings.
- Best for: teams whose key decisions happen in meetings.
- Watch-outs: decisions made outside meetings are not captured.
How to choose
| If your problem is… | Start with |
|---|---|
| Knowledge is written but hard to find | Enterprise search (Glean, Onyx, Rovo) |
| People do not write things down | A memory system (Reattend) |
| Decisions happen mostly in meetings | Meeting notes tool |
| You need verified answers for customer teams | Guru or a wiki |
| You cannot use the public cloud | Onyx, or Reattend on-premise (scoped on request) |
| You are losing knowledge when people leave | A tool with exit and handover workflows (Reattend), plus a knowledge transfer plan |

Frequently asked questions
What is organizational memory software?
Software that helps an organization keep and recall what it knows: decisions, reasons, commitments, processes and context. It ranges from wikis where people write knowledge down to tools that capture it from everyday work.
What is the best organizational memory software?
It depends on how your knowledge is created. If people already write good documents, a wiki with AI search may be enough. If knowledge is spread across many tools, enterprise search helps. If the problem is that decisions are never written down, you need a tool that captures them as work happens.
Is enterprise search the same as organizational memory?
No. Enterprise search finds what already exists in your tools. Organizational memory also covers what was never written down: decisions made in calls, commitments in conversations, and the reasons behind them.
