Biome 1.4 — Persistent Memory Arrives

Your agent now remembers context across sessions — no more repeating yourself. Before 1.4, every session with Biome started cold. The agent had no idea that you prefer bullet-pointed summaries, that your Linear workspace is called "Seed", or that you never want calendar invites sent before 9 am. You had to re-teach it each time. That changes today.

Selective recall, not total recall

We deliberately did not build a system that stores everything. A memory layer that remembers every message becomes noise. Instead, Biome tags facts worth keeping — preferences, recurring tasks, relationships between contacts, project names — and discards conversational filler automatically.

The result is a memory store that stays small and accurate, rather than growing into an unmanageable log you'd need to prune yourself.

Memory decay

Facts have a half-life. A preference from eight months ago that you've never reinforced fades and eventually drops. This keeps the memory layer accurate as your habits change, without you having to manually prune it.

Think of it less like a database and more like the way a good colleague internalises your working style over time — picking up the consistent signals, letting the one-off requests fade.

User-controlled forgetting

Open Settings → Memory at any time to inspect exactly what Biome knows, edit individual facts, or wipe the entire store. Your agent's memory is your data. Full stop.

We built the inspection view before we built the memory layer itself. If you can't see what the agent knows, you can't trust it — and trust is the whole product.

What's included in 1.4

Persistent memory is live in 1.4 for all plans. Pro users get cross-device sync so memory follows you between machines — your agent knows your preferences whether you're on your MacBook at home or your Mac mini at the office.
