CogniMemo vs Rivault: Features, Pricing & Which Is Better (2026)
A side-by-side comparison of CogniMemo and Rivault — features, pricing, and ideal use cases — to help you decide which AI tool fits your workflow.
CogniMemo
CogniMemo
Persistent, context-aware memory layer that connects data and apps to AI for smarter, human-like reasoning.
Key features
- Persistent Memory Storage: Stores structured and unstructured information across sessions so agents and applications retain long-term context and user history.
- Context-Aware Retrieval: Returns relevant memories based on contextual signals to inform model outputs and reduce irrelevant or repetitive responses.
- Connectors & Integrations: Ingests data from external sources (apps, docs, databases, APIs) via connectors or ingestion pipelines to centralize knowledge for recall.
- APIs and SDKs: Provides programmatic interfaces for reading, writing, querying, and managing memories so developers can integrate persistence into agents and apps quickly.
- Linking & Metadata Management: Organizes memories with links, tags, and metadata to enable semantic search and relationship-aware recall across related items.
- Privacy & Access Controls: Configurable retention, sharing, and access settings to help teams control where memories are stored and who can access sensitive context.
- Web application for saving and organizing information (login at app.cognimemo.com)
- Agent memory primitives (repository tagline: "Memory for AI Agents in 6 lines of code")
- Repository contains Docker Compose configuration for containerized deployment
- Python project structure (pyproject.toml, poetry.lock) indicating a Python backend
- Database migration tooling present (alembic.ini) suggesting persistent storage with migrations
- Environment configuration (.env.template) and entrypoint scripts for deployment
- Support for notebooks, tools, and logs in the repo structure (indicative of developer tooling / examples)
Best for
- Personal Assistant Memory: Enable virtual assistants to remember preferences, past interactions, and contextual details to provide personalized follow-ups and recommendations.
- Agent-Oriented Workflows: Give multi-step AI agents persistent state so they can recall prior tasks, variables, and outcomes across sessions for continuous task completion.
- Customer Support: Maintain long-term customer histories and conversation threads so support agents and bots can resolve issues faster without repeated questions.
- Knowledge Management: Centralize company documents, notes, and insights into a searchable memory to surface relevant information during research and decision-making.
- Developer Prototyping: Rapidly add persistent memory to prototypes and applications via SDKs and APIs to test memory-driven features and agent behaviors.
- Research & R&D Context: Preserve experimental context, configurations, and observations so models and teams can reason over historical research data and iterations.
- Personal or team knowledge base and note-taking with AI-assisted organization
- Providing persistent memory storage for AI agents (agent state, conversation memory, embeddings store)
- Self-hosted deployment for privacy-sensitive memory storage using Docker and Python
- Developer integration and experimentation with agent memory primitives and tooling
Rivault
Rivault
A zero-knowledge vault that lets AI agents request sensitive data on demand, unlocked by Face ID or passkey and redacted after each task.
Key features
- Zero-knowledge Vault: Sensitive data is encrypted client-side so Rivault never has access to the underlying values by default.
- Per-request Auth: Every agent access triggers a fresh authorization request that you approve with Face ID or a passkey.
- Deterministic Redaction: Data is scoped to a single task and redacted from the agent's context after completion.
- Agent-agnostic Integration: Works with chat-based AI agents and Computer Use Agents that automate browser or desktop flows.
- Ownership of PII: Store SSN, payment info, phone numbers, and emails once and reuse without leaving copies in session logs or memory.
- Biometric Unlock: Face ID or passkey approval keeps the human in the loop for every sensitive field release.
Best for
- Agent-driven Bookings: Approve passport and card details on-demand when an agent books flights or hotels.
- Automated Form Fill: Let CUAs complete government or insurance forms without leaving PII in browser logs.
- Customer Support Delegation: Grant scoped access to account numbers when an agent handles a service call for you.
- Recurring Task Automation: Reuse stored credentials across many agent workflows without pasting them each time.
- Enterprise Agent Deployments: Add a consent + audit layer for teams deploying agents that touch sensitive employee or customer data.
