AI Infrastructure Tools

The truth is, we’re juggling more apps than ever. From important links in slack to comments in notion to emails in Gmail, information is scattered across multiple places. This leads to time wasted on searching rather than doing. With Cortex, your agents can now search links, documents, and scattered information across all your apps workplace knowledge.

What to Consider

Cortex is best known as a memory layer for AI agents—helping teams persist, retrieve, and reuse knowledge so assistants stay context-aware over time. The alternatives landscape branches into a few distinct camps: tools like Super package knowledge reuse into team-facing workflows (department agents, RFPs, digests), while xdge AI (Ayraa) leans into enterprise search plus meeting capture and proactive insights. Klu emphasizes fast, encrypted cross-app “internal Google” search and chat, DeltaMemory goes deeper on structured long-term agent memory with extraction/knowledge-graph and “forgetting,” and Pieces for Developers focuses on local-first, on-device memory and snippet/context recall tailored to engineers.

In evaluating options, we weighed how well each product fits the intended user (agent builders vs business teams vs developers), the depth and breadth of integrations, and whether the experience is embedded in day-to-day workflows or centered on a search portal. We also considered security/privacy posture (including local-first approaches), reliability signals from reviews, and practical scalability factors like setup complexity and ongoing maintenance overhead.

Super leans into operational knowledge workflows rather than acting primarily as a behind-the-scenes memory layer for agents like Cortex. It’s especially compelling when the goal is to eliminate repetitive internal questions and turn existing docs into dependable answers for teams that field the same requests every week.

A key differentiator is how Super packages knowledge reuse into specific, high-value motions: RFP and bulk questionnaire support, onboarding help, and structured “ask once, reuse forever” flows. Instead of building an agent framework from scratch, teams can spin up specialized agents by department (Sales, HR, Compliance, Product) so each function gets answers in its own language.

Super also emphasizes in-the-flow usage, making it easier to pull quotes, past decisions, and relevant context while working—less tab-switching, more getting to an answer. The result is a more turnkey experience for business teams that want measurable workflow acceleration, not just better retrieval primitives.

For teams evaluating Cortex specifically, Super is a strong alternative when success is defined by speed-to-output on common business processes, like responding to security questionnaires or keeping internal enablement current with lightweight automation.

Best for

Best for SMB and mid-market teams that want department-specific assistants for onboarding, enablement, and RFP workflows.

Standout features

✓Department-specific agents
✓RFP and bulk questionnaire workflows
✓Weekly digests and reporting automation
✓In-the-flow knowledge retrieval

xdge AI

AI agents for your busy work

Ayraa is built for teams that want search plus proactive insight surfacing, not just a memory substrate for agent builders like Cortex. It aims to reduce the time spent hunting for context by pairing fast enterprise search with an “insights” layer that brings the right information forward.

Where Cortex is often evaluated on how well it helps agents remember and retrieve, Ayraa stands out when meetings and ongoing workstreams are central to knowledge capture. Its Smart Meeting Assistant and Automated Insights make it a better fit for organizations that live in calls and need outcomes, summaries, and follow-ups to be as searchable as documents.

Ayraa also differentiates through curated knowledge and advanced query capabilities, which can help teams ask more nuanced questions than basic keyword lookups. Personalized recommendations further shift the experience from reactive retrieval to guided discovery, useful for roles like marketing, social, and cross-functional operators who need context quickly.

If the priority is a broader work assistant that blends meeting intelligence with enterprise search and recommendations, Ayraa is often the more direct match than a pure agent-memory approach.

Best for

Ideal for knowledge workers who want enterprise search combined with meeting capture and proactive insights.

Standout features

✓Smart Meeting Assistant
✓Automated Insights and recommendations
✓Lightning-fast enterprise search
✓Advanced query capabilities

Klu

Internal search engine powered by AI.

Klu feels like an internal Google for teams, with a strong emphasis on speed, simplicity, and privacy-forward search across the apps work actually happens in. Compared with Cortex’s agent-memory framing, Klu is the better alternative when the primary job is helping people instantly find the right artifact across tools and then chat with it.

Its core strength is cross-app coverage: content scattered across Slack, Drive, Notion, Trello, and more becomes queryable through a single interface. The conversational layer makes it practical to ask direct, day-to-day questions and get concise answers without manually opening and skimming multiple sources.

Klu also stands out for UX polish and responsiveness, which matters when adoption depends on being faster than current habits. The product’s privacy and encryption stance is a deciding factor for teams that treat secure handling of work docs as table stakes.

Trade-offs versus Cortex tend to center on depth of agent-building capabilities versus end-user search experience. If the goal is widespread employee adoption of fast, encrypted, cross-app retrieval, Klu is a strong fit.

Best for

Best for teams that need fast, encrypted cross-app search with a chat interface.

Standout features

✓Cross-app search hub
✓Chat with your work data
✓Encryption and privacy by default
✓Fast, polished user experience

DeltaMemory

Fastest cognitive memory for AI Agents

Learn more →

DeltaMemory takes a more structured approach to long-term agent memory than many retrieval-first systems, positioning itself as a dedicated memory engine rather than workplace search. For teams using Cortex as an agent memory layer, DeltaMemory becomes compelling when “remembering” needs to look more like durable facts and relationships, not just similar chunks.

Its design focuses on fact extraction and a knowledge graph, which can help agents maintain consistent understanding over time and reduce drift across long-running conversations. The notion of “biological forgetting” adds a lever for keeping memory relevant, preventing old or low-signal details from crowding out what matters.

Integration is framed around a small set of core actions—ingest, recall, reflect—making it easier to reason about memory flows inside agent architectures. That can be attractive to platform teams who want clear primitives they can standardize across multiple agents and products.

If the main requirement is a purpose-built memory backbone with structure, reflection, and lifecycle controls, DeltaMemory is a credible alternative to Cortex’s broader memory-layer positioning.

Best for

Best for AI platform teams building agents that need structured, durable long-term memory.

Standout features

✓Fact extraction into structured memory
✓Knowledge graph-based recall
✓Forgetting and memory lifecycle controls
✓Ingest, recall, reflect primitives

Pieces for Developers

On-device AI development assistant for your entire workflow

4.7 · 35 reviews

Pieces for Developers is optimized for engineers who want long-term recall without sending sensitive context to a cloud service. While Cortex targets agent memory broadly, Pieces is a stronger alternative when the requirement is local-first, on-device memory for coding workflows and everyday developer context.

It excels at capturing and resurfacing snippets, solutions, and working context across tools, so developers stop re-discovering fixes buried in old repos, chats, or notes. Time-based recall also makes it useful for picking up where work left off, turning recent activity into searchable, assistive context.

Pieces differentiates through deep presence inside developer surfaces like VS Code, browsers, and knowledge tools such as Obsidian, reducing context switching. It’s less about building custom agent pipelines and more about giving individual developers and teams a “context powerhouse” that improves reuse and continuity.

If choosing between Cortex and a developer-first memory tool, Pieces is the better fit when privacy, offline capability, and code-centric recall matter as much as the model output.
