Give your agents a bigger effective memory
Context Controller manages your agents' context windows automatically — compacting what's stale, protecting what matters, and recalling what was evicted. Run 10× longer sessions without hitting the wall.

The context window is the new RAM
Agents fail when they run out of memory mid-task. Truncating from the front destroys reasoning. Summarizing everything destroys detail. Context Controller does neither — it manages memory like an OS.
Smart compaction
Tool outputs, logs, and transcripts are summarized in place with provenance links — you keep the facts, lose the bytes. Typical sessions reclaim 40–70% of used tokens.
Priority-based eviction
Tag messages pinned, high, normal, or low. When pressure rises, the lowest-value content goes first — oldest first — and your system prompt and user intent are never touched.
Semantic recall
Evicted content isn't gone. It's embedded, indexed, and retrievable — the agent can pull back exactly what it needs, when it needs it, for a fraction of the token cost.
Multi-agent shared context
Swarm and pipeline agents share a managed context pool with per-agent views, so handoffs carry state without duplicating the whole window.
Observability
Every compaction, eviction, and recall is logged with before/after token counts. Know exactly where your context budget goes — per session, per agent, per policy.
Drop-in integration
A thin proxy in front of any model API, or an SDK for Python and JS. Keep your prompts, your tools, your stack — add one line and get managed memory.
Three steps to unlimited-feeling memory
Connect
Point your agent at the Context Controller proxy or wrap your client with the SDK. No prompt changes required.
Configure policy
Pick a compaction strategy, set priority tiers, and define what must never be evicted. Sensible defaults ship out of the box.
Run forever
Sessions compact themselves as they grow. Watch token usage, replays, and recalls in the dashboard.

Illustrative quotes from our design partners — real customer stories are on the way.
"Our support agent used to die at message ~40. With Context Controller it runs full 8-hour shifts. Compaction paid for itself in the first week."
Illustrative — Eng lead, customer-support automation
"Priority eviction is the feature I didn't know I needed. The agent keeps the user's goal pinned and throws away the noise. Reasoning quality went up, costs went down."
Illustrative — Founder, dev-tools startup
"Semantic recall is wild — our research agent pulls back a PDF it 'forgot' three hours ago and cites the page. It feels like the agent actually remembers."
