Our verdict on WithMemory

WithMemory is a hosted memory API and JavaScript SDK for AI agents that need to carry durable facts across sessions, models and restarts. It suits solo developers and small teams seeking a straightforward way to store and retrieve agent context. Namespaces can separate memories by user, project, research area or agent, while ranked semantic recall returns prompt-ready context. Agents can write known facts directly or send free-form text for LLM-based extraction.

The three monthly plans scale by memory and API-call allowance. Free provides 1,000 memories and 10,000 API calls, with the default extraction prompt and community support. Basic costs $9 per month for 10,000 memories and 100,000 API calls; it also uses the default prompt and includes email support. Pro costs $29 per month for 100,000 memories and 1,000,000 API calls, adds a custom extraction prompt, and includes email support with a 48-hour response. Pro also adds isolated containers and scoped credentials. These tiers make the product accessible for evaluation and offer a clear capacity path, though the listed plan features center on quotas, extraction and access controls.

Its feature set covers both durable storage and a separate unauthenticated cache with a 24-hour lifetime, plus methods to list, retrieve and delete memories. The API is cloud-hosted; the JavaScript SDK is distributed through npm, and agents that can make HTTP requests are supported. That keeps the integration model focused rather than offering a range of SDK languages or deployment choices. The main caveat is service maturity: the terms describe WithMemory as alpha and best-effort without a formal SLA. Teams comfortable with that posture may find it a practical fit for hosted agent recall; teams requiring a formal reliability commitment or self-hosting should look elsewhere.
