Atlaso: Does One Memory Layer Fix Every AI Tool in 2026?
Atlaso is a cross-tool AI memory layer from Atlaso Labs that installs into Claude Code, Cursor, Codex, Claude Desktop, OpenCode and Antigravity via a single shell command, capturing decisions after each turn and injecting the top five relevant memories before the next one. Its published four-judge study on LongMemEval-S (n=500, shared Qwen 3.5-9B reader) shows Atlaso beating mem0 by 9.8 to 14.8 percentage points, and also documents an 11.5-point loss to mem0 on the adversarial LoCoMo subset plus a failure to reproduce mem0's headline 93.4 percent figure. The shipped product lags the research: supersede logic is not triggered automatically, injected memories are invisible from the terminal, and there is no team memory or self-hosting. Free covers one device and one tool; Pro is 10 dollars a month and Build is 25.
