Knowledge Checker is a proactive agent in Superhuman Go that works quietly in the background as you write. It detects factual claims and assertions in your text, then surfaces supporting evidence, enrichment, or possible contradictions from your connected knowledge sources—all without asking you to stop writing or switch tabs.
Instead of finishing a draft and then hunting through docs, Slack, or your drive to confirm a number, Knowledge Checker brings the right information to you at the moment you make the claim. A subtle underline signals that evidence is available. One click shows you what it found and where it came from. Another click inserts it into your text.
Note: The Knowledge Checker agent is a beta feature currently available within Superhuman Pro, Business, and Enterprise plans.
Why use it?
Every claim you write has a hidden research loop behind it—stop, tab-switch, search, scroll, find the figure, switch back, resume. It costs minutes each time, and often the thread of your thought is lost. Worse, some gaps you never see at all: the case study that would have strengthened your point, or the outdated figure that slips through unnoticed.
Knowledge Checker closes that loop before it opens. It helps you:
- Catch inaccuracies and outdated information before a document leaves your hands.
- Strengthen vague claims with internal figures, case studies, and benchmarks you may not have known existed.
- Stay in flow by surfacing evidence inline instead of forcing a search.
- Send with confidence, knowing every suggestion shows exactly where it came from.
Connectors
Knowledge Checker currently can draw on the following connected sources:
- Superhuman Docs
- Microsoft Office Suite
- Google Suite
- Slack
- Atlassian Jira & Confluence
Knowledge Checker only references the sources you connect, and every inline suggestion shows exactly which source it came from.
Getting started
Install the agent. Open the agent store in Superhuman Go and install Knowledge Checker.
Connect your data sources. Go to the Agent settings page and configure the knowledge sources you want Knowledge Checker to use. Any connectors you’ve already set up in Go settings are used automatically—no need to reconnect them.
- Start writing. Knowledge Checker begins monitoring your writing and surfacing signals as you go.
How to use Knowledge Checker
Proactive underlines
As you write, Knowledge Checker recognizes the claims behind your words and adds a subtle underline wherever supporting evidence is available.
- Click the underline to see the evidence, where it came from, and why it’s relevant.
- Accept it in one click to insert the source or figure directly into your text, without leaving the document.
Go chat
For a deeper look, open the Go side panel to chat with Knowledge Checker. You can ask follow-up questions about a detected claim or explore your connected sources further.
What Knowledge Checker can do
- Proactive claim understanding: Recognizes the assertion behind your words, so what surfaces is relevant to what you actually meant.
- Data enrichment: Surfaces internal figures, case studies, and benchmarks that could strengthen a claim, even ones you didn’t know existed.
- Contradiction detection: Flags when a figure or assertion conflicts with your connected sources, before it leaves your draft.
- Source transparency: Every suggestion shows exactly where the evidence came from.
- Source management: Add or remove connected knowledge sources at any time from the Agent settings page.
Privacy and control
Knowledge Checker only uses the sources you choose to connect, and it always shows the origin of any evidence it surfaces. You manage which sources are connected from the Agent settings page, so you stay in control of what the agent can reference.
