Plans
Parametric Memory offers four paid tiers. Every customer gets their own isolated substrate on real infrastructure — Professional and Team run on a dedicated droplet, while Starter and Solo run as isolated tenants on a shared host. There is no unpaid access level.
The tiers
| Starter | Solo | Professional | Team | |
|---|---|---|---|---|
| Price (USD) | $5 / month | $9 / month | $29 / month | $79 / month |
| Atoms | 1,000 | 10,000 | 100,000 | 500,000 |
| Bootstraps / month | 200 (~6/day) | 1,000 (~33/day) | 10,000 (~333/day) | 20,000 (~667/day) |
| Storage | 100 MB | 500 MB | 2 GB | 10 GB |
| Substrates | 1 | 2 | 3 | 5 |
| Hosting | Shared host | Shared host | Dedicated droplet | Dedicated droplet |
All prices are in US dollars (USD).
What "bootstraps" means
A bootstrap is one call to memory_session_bootstrap — the call your AI makes at the start of each session to load relevant context. Each session typically uses one bootstrap. 200/month covers roughly 6 Claude sessions per day; 1,000/month covers roughly 33.
What "atoms" means
An atom is one named piece of memory — one key/value pair. 1,000 atoms covers approximately 2 months of daily use. 10,000 atoms covers approximately 18 months of daily professional use for a solo developer. You can check your current usage on the Dashboard at any time.
Overage pricing
If you write above your atom limit via the API, those atoms are charged at $0.01 per atom above your tier limit — the MCP tools enforce the limit by default. Overages are reported to Stripe via metered billing and appear on your next invoice. You can set a spend cap to prevent unexpected overage charges.
Starter vs Solo — which should I choose?
- Starter if you are trying Parametric Memory for the first time, or use Claude occasionally
- Solo if you use Claude for personal projects, solo development, or moderate daily AI use
Solo vs Professional — which should I choose?
- Solo if you have a single main project and moderate daily AI use
- Professional if you run multiple agents, have intensive daily use, or frequently hit the bootstrap limit on Solo
When to choose Team
Professional and Team both run on a dedicated DigitalOcean droplet rather than a shared container. Choose Team (over Professional) when:
- You need guaranteed compute isolation from other customers — your instance runs on its own server with no shared resources
- You want 500,000+ atoms for large-scale institutional memory
- Multiple people on your team will share the same memory instance
- You need multiple memory substrates for different projects or teams (multi-substrate is rolling out to Team customers — contact us)
- You want the best possible response times for bootstraps and large batch operations
What "dedicated" means in practice: On shared tiers (Starter and Solo), your container runs alongside other customers on the same server. Resources are allocated per container, but you share the underlying host. On Professional and Team, you get an entire server to yourself — provisioned from a pre-built image for faster startup, running in your chosen region, with full CPU and memory exclusively for your workloads.
Money-back guarantee
All paid plans include a 7-day money-back guarantee. If Parametric Memory does not work for your use case, contact support within 7 days of your first payment for a full refund.
Changing plans
You can upgrade at any time from the Dashboard (upgrades apply immediately). Plans are upgrade-only — downgrades are not supported. See Upgrade Plan and Downgrade Plan (why downgrades aren't supported, and what to do instead).
