Persistent memory

for AI agents.

One endpoint. Every project, every device, every session.
Your agent forgets everything between sessions. Inertia fixes that.

~/.claude.json

{
  "mcpServers": {
    "inertia": {
      "type": "http",
      "url": "https://inertia.tools/mcp/YOUR_TOKEN"
    }
  }
}

That's it. Your agent remembers now.

What your agent can do

inertia_remember

Store decisions, patterns, preferences, mistakes — anything worth keeping. Auto-tagged by context.

inertia_recall

Semantic search across everything. The right memory surfaces before your agent responds.

inertia_update

Patch memories in place. Fix what's outdated without losing the original timestamp or sequence.

inertia_forget

Delete anything. Your data, your control. No retention after deletion.

preference "This project uses tabs, not spaces"

hard-won "The deploy script breaks if NODE_ENV isn't set"

style "User prefers concise responses"

mistake "We tried approach X and it failed because Y"

decision "The auth system was refactored in PR #47"

No tiers. No games. No "contact sales."
I charge $2 because that's all it costs.

Your memories are yours. Encrypted at rest, scoped by your account.

We can't read them. We don't train on them. We don't sell them.

Export or delete everything anytime. No retention after deletion.

Auth via GitHub OAuth. No passwords to manage.
