A new two-tier memory system in Archon
Working memory decays. Knowledge memory persists. Here’s why we built two.
Two-tier memory · shipped May 14, 2026
Most AI chatbots have one memory bucket. Everything you say gets dumped in, the model rummages around when relevant, and over time the signal drowns in the noise. The output becomes generic. The advice gets vague.
Today we’re shipping a two-tier memory system in Archon: working memory that decays after 7 days, and knowledge memory that persists indefinitely. The split is the entire point.
The forgetting is deliberate. If Archon remembered every passing comment, the advice would drift to generic over time.
Why two tiers
When you chat with Archon about “the launch on Thursday” or “that signup from yesterday,” those facts matter for this week — and then they don’t. They’re context, not knowledge. Working memory holds them, decays them in 7 days, and stays out of long-term advice.
But when you tell Archon something like “LinkedIn converts at $99 without negotiation, the $39 tier is dead,” that’s a structural fact about your business. It should inform every plan from now on. It belongs in knowledge memory — permanent, surfaced when relevant, weighted heavily.
How items get promoted
Two paths. Explicit: you type “remember this” and Archon promotes the item. Auto: a small classifier (Claude Haiku) reads each turn and flags structural facts — pricing decisions, channel insights, customer patterns — for promotion. You see what got remembered and can revoke anything in one click.
What you’ll feel as a user
In the short term: cleaner conversations — Archon doesn’t bring up irrelevant context from last week. In the long term: better advice that compounds. The longer you use Archon, the more it knows about your business specifically, and the less it sounds like a generic tool.
The full memory inspector is in the dashboard under Settings → Memory. You can see every knowledge entry, when it was added, and revoke any of them.
Try Archon.
$1.30 / day. 3-day free trial, no card. The memory system is on by default.
