Any sandbox, one filesystem.
A persistent filesystem shared across sandboxes, sessions, and handoffs — so work survives when an agent stops and the next one picks up where it left off. FUSE-mount it locally, semantic-grep it with vector and BM25 in parallel, and grant secrets per agent from a built-in vault.
One filesystem every sandbox can see.
Files written from one sandbox are instantly visible to the next — across sessions and
across handoffs. Copy files in with drive9 fs cp, or FUSE-mount a path with
drive9 mount and work on it like a local folder. The state outlives any
single agent run.
# one filesystem, shared across every sandbox $ drive9 create ✓ drive ready · :/ is shared # write a file from anywhere $ drive9 fs cp ./report.md :/notes/ ✓ report.md → :/notes/report.md # mount it locally over FUSE $ drive9 mount :/data ~/data ✓ :/data mounted at ~/data
Search by meaning. Grant secrets per agent.
drive9 fs grep runs vector and BM25 search in parallel, so a query like
"pricing strategy" finds the right lines whether or not they use those words. And the
built-in vault hands each agent only the secrets it needs — drive9 vault grant
--agent alice aws scopes a credential to one agent. Secrets are graduating into
their own product — see vault9.
# semantic grep — vector + BM25, in parallel $ drive9 fs grep "pricing strategy" / :/notes/pricing.md:12 :/notes/q3-plan.md:4 # secrets vault — grant per agent $ drive9 vault grant --agent alice aws ✓ aws scoped to agent alice
Write once. Read anywhere. Search by meaning.
drive9 is the shared memory of files that agents pass between each other.
One drive, every sandbox
Create a drive and it's reachable from any sandbox or session. Files written by one agent are there for the next — no copying state between runs.
Local over FUSE
Mount any path with drive9 mount and it behaves like a local folder — edit, diff, and tail files with the tools you already use.
Grep by meaning
Semantic grep runs vector and BM25 together, so agents retrieve the right context fast — and the vault keeps each agent's secrets scoped to just that agent.
The filesystem under your agent stack.
Pair drive9 with compute, data, memory, and observability — one agent-native stack.
Give your agents one filesystem.
drive9 is live. Use-first, claim-later — no signup to start. Install the CLI or point your agent at the sys9 skill.
