Maximem
Maximem builds a memory and context layer for AI. Synap gives the agents you build persistent, scoped recall across sessions and frameworks; Vity carries your own context between ChatGPT, Claude, Gemini and Perplexity through a Chrome extension.
What is Maximem?
Maximem is an AI memory and context-management company founded in 2025, headquartered in San Francisco with engineering in Bangalore. It ships two distinct products built on the same idea: an agent is only as useful as what it remembers.
Maximem Synap is the context-management stack for the AI agents development teams build. A conversation turn does not simply land in a database. It is ingested, its meaning is extracted into structure rather than raw text — facts, preferences, episodes, emotions and temporal events — and written asynchronously across a vector store, a graph and a file store, so that writing never blocks the agent. Retrieval then queries all three at once, and the narrowest applicable scope wins. Around that pipeline sit three named mechanisms: MACA generates a memory architecture per agent from a use-case description; validated compaction returns a score and a preserved-facts count instead of a blind summary; and IACS isolates memory automatically along a User, Customer and Client chain, so one tenant's context never surfaces in another's session.
The published numbers are 92% on LongMemEval, 93.2% on LoCoMo and 15 ms P50 retrieval latency, measured on an evaluation harness the company open-sourced so the figures can be re-run. Synap ships 22 native framework integrations — LangChain, LangGraph, LlamaIndex, OpenAI Agents, CrewAI, AutoGen, Claude Agent SDK, Vercel AI SDK, LiveKit Agents and Pipecat among them — plus REST and WebSocket APIs, webhooks, custom memory schemas and A2A protocol support. It is model-agnostic, and BYOK arrives at the Pro tier.
Maximem Vity is the consumer half: an encrypted personal vault, reached through a Chrome extension, that carries one memory between ChatGPT, Claude, Gemini and Perplexity instead of making you restate yourself in each one.
Deployment runs from a managed cloud on AWS and GCP, with all customer data stored in the United States, through self-hosted, to a fully air-gapped configuration with no outbound internet access. Enterprise plans add VPC, SSO and SAML, configurable RBAC and custom SLAs.
What it does
- Give an AI agent memory that survives sessions, channels and months
- Resolve entities automatically, so that Sarah, Sarah Chen and SC become one person
- Isolate memory across user, customer and organisation scopes
- Compact context and measure what the compaction actually preserved
- Pre-fetch relevant context before the agent asks for it, at 15 ms P50
- Plug memory into 22 agent frameworks without rewriting the agent
- Carry one personal memory between ChatGPT, Claude, Gemini and Perplexity
When to use Maximem / When not to
A quick filter to help you decide if Maximem is the right fit.
When to use Maximem
- Engineering teams building AI agents that lose the thread between sessions
- Multi-tenant SaaS products that must isolate memory per user, per customer and per organisation
- Builders of voice and real-time agents working under a tight latency budget
- Security-conscious buyers who need a DPA and a self-hosted or air-gapped deployment
- Heavy users of several consumer AI tools who retype the same context in each one
When not to use Maximem
- Organisations whose procurement requires SOC 2, ISO 27001 or HIPAA certification today
- Customers bound to data residency outside the United States on the managed cloud
- Teams shopping for a plain vector database rather than a managed memory layer
- Non-technical buyers expecting to use Synap without writing any code
- People who want Vity outside Chrome, or on an iOS or Android app
How to use Maximem
A typical end-to-end flow, from setup to results.
- Create an account on synap.maximem.ai and generate an API key
- Try the behaviour in the public Playground first, before writing any code
- Install the SDK, @maximem/synap for JavaScript or its Python equivalent
- Instantiate the client with your key, then call memories.create to store a memory
- Call memories.search with a user ID and a query to recall the relevant context
- If you use a framework, follow its dedicated docs page and let Synap replace the native memory component
- Scope memory by user, customer and client so that tenants stay isolated
- Migrate memories from another provider using the Migrate section of the documentation
- For Vity, install the Chrome extension and complete the guided four-step setup
- Manage the personal vault from the Vity dashboard at app.maximem.ai
Pros & Cons
Pros
- Benchmark numbers come with an open-source evaluation harness, so they can be re-run instead of taken on trust
- Every plan gets every capability: tiers differ only on volume and service level
- The security page is unusually detailed and free of overselling, covering data flow, encryption, retention, deletion and isolation
- A DPA is available to every customer on request, with no plan requirement and nothing to negotiate
- The subprocessor list is published by name, with each provider's role and privacy policy linked
- No training on customer data, including at the external model providers, which work under zero-data-retention agreements
- A real free tier with no credit card, plus self-hosted and air-gapped options that remove third parties entirely
Cons
- No formal certification: neither SOC 2, ISO 27001 nor HIPAA, and the vendor itself points buyers who need them today to a competitor
- Managed-cloud data sits in the United States only; other regions are announced as in development, so there is no European residency yet
- A very young company, founded in 2025, whose first web capture dates from September 2025
- No complete postal address, no contact page and no legal notice; the legal name appears only in the homepage structured data
- The pricing FAQ contradicts the pricing table, promising a 14-day trial on a Growth plan that does not exist
- The 19 USD entry price is a launch offer against a 49 USD list price, and credit-metered consumption makes the monthly bill hard to forecast
- Vity is Chrome-only with no mobile app, and historical activity logs cannot be deleted by the user
Pricing & Plans
A permanent free tier is available. The Maximem Synap Trial plan grants 5,000 credits per month at no cost and requires no credit card, and Maximem Vity offers a free plan with limited credits. The lowest paid entry point published on the pricing page is the Synap Starter plan at 19.00 USD per month, presented as a launch offer against a 49.00 USD list price. The terms of service additionally price Vity Pro at 10.00 USD per month and Vity Super at 30.00 USD per month. Annual billing is advertised at 17% below monthly billing.

Data, GDPR & hosting
A consolidated view of how Maximem handles your data.
GDPR overview
Maximem never claims GDPR compliance in so many words, and neither an Article 27 representative nor a DPO is named anywhere on the site. What it does offer is concrete. A Data Processing Agreement is available to every customer on request at support@maximem.ai, with no plan requirement and nothing to negotiate. That agreement names Maximem as processor and the customer as controller, and covers subprocessor obligations, confidentiality and security duties, prompt breach notification, support for end users' access and deletion requests, deletion or return of data when the contract ends, and the standard international transfer clauses where they apply. A named subprocessor list is published. No formal certification is held: the company says it is still working towards them. Note also that historical activity logs cannot be deleted by users.
Who owns the data?
Under the Vity terms, you own your content — your prompts, memories and generated outputs — while Maximem owns the platform itself: the software, the brand and the underlying technology. Feedback and suggestions you send are the exception, and the company may reuse them freely. For Synap, the Data Processing Agreement makes the split explicit: the customer remains the controller and Maximem acts only as processor, handling data on documented instructions and never for its own purposes. The vendor states that no one on its team reads customer content, and that on a self-hosted deployment it holds no copy at all.
Reuse rights
You keep your prompts, memories and outputs, and nothing in the terms requires permission to reuse your own content: the dashboard lets you update, export or permanently delete it whenever you want. What you may not do is resell, clone or scrape the platform, or use it to build a competing service — the licence granted is personal and limited. Maximem states that it never reads customer content, never sells it and never uses it to train AI models, and that the external model providers it calls operate under zero-data-retention agreements which forbid training on your content as well. Feedback and suggestions are the one input the company reserves the right to reuse without asking.
Data retention & training
Hosting summary
Synap's managed cloud runs on Amazon Web Services and Google Cloud Platform, and all customer data is stored in the United States. Both providers are bound by contract as subprocessors, with no rights to the data beyond operating the infrastructure Maximem rents. Additional regions are described as in active development for customers with residency requirements, but none is available today. Customers who cannot place data with a third-party cloud can run Synap self-hosted inside their own environment, including a fully air-gapped configuration with no outbound internet access, in which case no subprocessor sees the data at all. Everything is encrypted in transit and at rest: TLS 1.2 or higher from the application, encrypted service-to-service traffic with mutual TLS on streaming and high-throughput paths, and encryption on disk for databases, search indexes, object storage and backups. API keys are kept only as a one-way hash and cannot be read back. Tenant isolation is enforced by the platform from the authenticated request, not by application code.
Things to keep in mind
Risks and trade-offs to weigh before adopting Maximem.
- Handing a persistent memory layer your users' conversations concentrates sensitive data in one place, and the blast radius of any breach grows with it
- The vendor holds no formal certification, so its security claims rest on its own description rather than on an external audit
- Managed-cloud data is stored in the United States, which may put European personal data outside the residency your own obligations assume
- Historical activity logs cannot be deleted by the user, so an expectation of deleting everything will not be fully met
- An agent that remembers can also remember something wrong, and a stale or mistaken fact propagates into every later answer
- Delegating context to a memory layer makes it easy to stop checking what the agent believes it knows about a customer
- Credit-metered pricing plus overage charges means cost scales with usage in ways that are hard to feel until the invoice arrives
Setup & Integrations
Technical difficulty
Two very different answers. Synap is a developer product: you create an account, take an API key and install the Python or JavaScript SDK, and a handful of lines is enough to store and recall a memory. A public Playground lets you try it before integrating, and each of the twenty-two frameworks has its own documentation page. Self-hosted or air-gapped deployment is markedly heavier and is scoped with the vendor. Vity needs no technical skill at all: install the Chrome extension and follow a guided four-step setup.

Frequently asked questions
What does Maximem actually do?
Is there a free plan, and what does the first paid tier cost?
Which agent frameworks and models does Synap work with?
Is my data used to train AI models?
Where is the data hosted, and can I get EU residency?
How long is data kept, and can I have it deleted?
Is Maximem SOC 2 or ISO 27001 certified?
Is there a mobile app, and what about the Chrome extension?
Should you pick Maximem?
Maximem is a technically serious piece of infrastructure. The performance claims come with an open-source evaluation harness, the twenty-two framework integrations are each documented, and the security page is one of the most candid you will read: it says where data lives, who touches it, how long it stays and what a full deletion actually erases, without dressing any of it up. Giving every plan every capability is an unusual choice, and it makes the entry tier genuinely usable rather than a teaser.
The counterweight is maturity. This is a company founded in 2025 with no formal certification — it says so itself, and even sends buyers who need SOC 2 or HIPAA today to a competitor. Managed-cloud data sits in the United States, so European residency is not an option yet. There is no complete postal address, no contact page and no legal notice; the legal name surfaces only in the homepage structured data.
Pricing deserves a second look before you commit. The 19 USD entry price is a launch offer against 49 USD, consumption is metered in credits whose cost per operation varies, and the pricing FAQ still advertises a fourteen-day trial on a plan that does not appear in the table. None of that is disqualifying, but it is worth pricing out at your real volume.
For a team that needs agent memory now and can live with a young vendor, the free tier and the public Playground make the evaluation cheap. For a regulated buyer, the sensible move is to wait for the certifications.
