The Terminology Evolution
From Chatbot to Copilot to Agent
| Era | Peak Term | Defining Characteristic | Coverage Peak | |—--|———--|————————|—————| | 2016-2022 | Chatbot | Conversational interface | 2023Q1 (154) | | 2021-2024 | Copilot | Human-AI collaboration | 2024Q1 (55) | | 2024-2025 | Agent | Autonomous action | 2025Q4 (62+) |
Each term represents a different mental model of AI's role:
- Chatbot: AI responds to queries
- Copilot: AI assists with tasks
- Agent: AI executes tasks autonomously
| Feature | Term | 2022 | 2024 | 2025 | 2022→2025 |
|---|---|---|---|---|---|
| agent | Agent/Agentic | 1 | 87 | 209 | +20,800% |
| chatbot | Chatbot | 18 | 95 | 110 | +511% |
| copilot | Copilot | 7 | 45 | 69 | +886% |
| autonomous | Autonomous | 39 | 52 | 57 | +46% |
"Agent" went from 1 mention in 2022 to 209 in 2025. The growth rate—20,800%—dwarfs every other autonomy term.

The Seminal Moments
First Mover: The Curiosity Agent (2018)
The earliest meaningful "agent" mention in the dataset:
”"New research from OpenAI shows how an AI agent with a sense of curiosity outperformed its predecessors playing the classic 1984 Atari game Montezuma's Revenge" — The Verge, 2018-11-04
Seven years before the boom. The concept existed in research; it hadn't reached product.
The Chatbot Era Peak (2023Q1)
ChatGPT's launch triggered a chatbot coverage explosion:
”"Microsoft releases an updated Bing app on iOS and Android in preview, adds chatbot functionality" — Windows Central, 2023-02-22, Position #3, 27 related
”"Microsoft says it is looking at limiting Bing chatbot conversations" — New York Times, 2023-02-17, Position #6, 22 related
”"Google's Bard announcement tweet had a GIF showing the AI chatbot making a factual error" — Reuters, 2023-02-08, Position #3, 21 related
The "chatbot" frame dominated because the product was conversational. You typed, it responded.
The Copilot Wave (2023-2024)
Microsoft's branding shaped the next frame:
”"Microsoft plans to bring OpenAI's GPT-4 to Excel, PowerPoint, Outlook, and Word" — Bloomberg, 2023-03-16, Position #14, 18 related
”"Microsoft unveils a Copilot keyboard key, shipping in new PCs" — 2024-01-04, Position #27, 55 related
"Copilot" positioned AI as assistant—you're still driving, AI is helping. This was a stepping stone to autonomy.
The Agent Crossover (Q4 2024)
The quarter where "agent" decisively overtook "chatbot":
”"Microsoft unveils 10 new AI agents for its enterprise-focused Dynamics 365 apps covering sales, finance, and more, ahead of Salesforce's Agentforce availability" — GeekWire, 2024-10-21
”"Sources: OpenAI plans to launch a new AI agent codenamed Operator, which can use a computer to take actions on a person's behalf" — Bloomberg, 2024-11-14
The Shift in Headlines:
| Pre-Crossover (2023) | Post-Crossover (2024-2025) | |———————|—————————| | "chatbot functionality" | "AI agents for enterprise" | | "limiting chatbot conversations" | "agentic AI capabilities" | | "chatbot making a factual error" | "agent codenamed Operator" |
The frame shifted from interface (chatbot) to actor (agent).
The Agent Era Arrives (2025)
”"Google unveils Deep Research, an AI tool to let its Gemini chatbot scour the web and write a detailed report" — The Verge, 2024-12-11
”"OpenAI partners with DoorDash, eBay, Instacart, Priceline, StubHub, Uber, and other companies to ensure that Operator respects their terms of service" — TechCrunch, 2025-01-24
”"ServiceNow says it plans to acquire agentic AI company Moveworks for $2.85B, its largest-ever acquisition" — Reuters, 2025-03-11
"Agent" now leads Techmeme. The thesis is the default.

What Changed
The Capability Threshold
Agents require capabilities chatbots don't:
- Tool use: Calling APIs, executing code
- Planning: Multi-step reasoning
- Memory: Context across sessions
- Autonomy: Acting without human-in-the-loop
These capabilities crossed from "research demo" to "production ready" in 2024. The language followed the capability.
See agent memory architecture for the technical patterns.
The Enterprise Pull
Enterprises don't buy chatbots. They buy automation.
The coverage shift correlates with enterprise AI adoption rising from 29% (2023) to 43% (2025). Enterprise buyers want agents that do work, not chatbots that discuss work.
The Language Signal: When enterprises started buying, the product descriptions changed. "Chatbot" signals consumer toy. "Agent" signals enterprise tool.
The Investment Signal
VC language mirrors coverage:
”"Simular building AI agents for Mac and Windows raised $21.5M" — 2025-12-07
”"Chinese humanoid robot startup Galbot raised over $300M at a $3B valuation" — 2025-12-25
You don't raise at $3B for a "chatbot." You raise at $3B for an "agent" that can do physical work.

The Implications
1. The Frame Is Now Correct
The agent thesis argued that agentic AI—software capable of perception, reasoning, action, and learning—is distinct from generative AI. The coverage data confirms the market has adopted this frame.
If you're still pitching "chatbots," you're a cycle behind.
2. The Crossover Was Sudden
The shift from chatbot to agent wasn't gradual. It was a phase transition:
- 2023Q4: Chatbots still dominated
- 2024Q4: Agents crossed over
- 2025Q4: Agents dominant
The Speed of Frame Shifts: Industry language can flip in 2-3 quarters. The "chatbot" frame lasted ~7 quarters after ChatGPT. The "agent" frame is now the default.
3. The Next Frame Is Coming
Coverage patterns suggest what comes next. We're seeing early mentions of:
- "Swarms" — Multi-agent coordination
- "Operators" — Agents with computer use capability
- "Digital workers" — Full task replacement
The agent frame will be superseded, probably within 24 months. Track the language to track the capability frontier.

The Arc of Autonomy
| Phase | Years | Dominant Term | Mental Model | |——-|——-|—————|————--| | Interface | 2016-2022 | Chatbot | AI responds to queries | | Assistance | 2022-2024 | Copilot | AI helps with tasks | | Autonomy | 2024-2026 | Agent | AI executes tasks | | Coordination | 2026+ | Swarm/Workforce | AI teams execute workflows |
Each phase expands the scope of what AI does:
- Answer questions
- Help with tasks
- Complete tasks
- Coordinate complex work
The state of agents tracks where we are in this arc.

The workforce is evolving—literally. AI agents are no longer experimental tools but genetically optimized systems driving 50%+ of enterprise operations autonomously.
Agent Memory: From Stateless to Stateful AI
LLMs are stateless by design. Agents require state. The memory architectures—context management, vector stores, knowledge graphs—that transform amnesiacs into collaborators.
