Hydrate vs Hindsight (Vectorize)
personal memoryMECHANICALLY THE CLOSEST competitor: auto-recall injects as additionalContext pre-prompt (= Hydrate read path), auto-retain after each session, + shared team memory via bankId. But Codex-scoped, hosted cloud, not cross-vendor-live or canon-with-attribution.
Hindsight is, mechanically, the closest tool to Hydrate we have found: it injects recalled memory as additionalContext before the prompt and auto-retains after each session, Hydrate's exact read/write shape, and it has a shared team mode. The difference is narrow and specific, and worth stating precisely: Hydrate is cross-vendor live (a Claude-written fact reaches a Codex agent in the same sequence), its canon propagates with attribution over a git remote you control rather than a shared cloud bank, and it is local-first and offline-capable. "Automatic injection" alone no longer separates the two, those three lines do.
What Hindsight (Vectorize) is
| Stack / runtime | Hook-based memory layer (recall + retain hooks); Hindsight Cloud or self-managed server |
| Licence | Commercial (Vectorize) |
| Storage | Memory banks (server-side on Hindsight Cloud) |
| Hooks | Auto-recall (before every prompt) + auto-retain (after every session) |
| Injection | Auto-recall injects as additionalContext before the model (invisible in terminal) |
| Scope | Codex-first (also OpenCode); project-scoped banks |
| Maturity | Commercial; Vectorize |
| Price | Hindsight Cloud (tiers — verify) |
| Version referenced | 2026 |

Where Hindsight (Vectorize) leads
- Codex-native auto-recall/auto-retain with the exact additionalContext pre-prompt pattern
- Zero-local-daemon team mode (Hindsight Cloud shared bank, follows you across machines)
- Project-scoped banks prevent cross-repo leakage
Where Hydrate leads
- Cross-vendor LIVE (Claude-written fact -> Codex agent same sequence); Hindsight is Codex-centric
- Canon propagation with ATTRIBUTION over a git remote you control (vs shared bankId pool on cloud)
- Local-first single binary, offline-capable (vs hosted cloud bank)
- Orchestration + three-layer bootstrap
Verification notes
CLOSEST competitor on mechanism (pre-prompt injection + auto-capture + team mode). Resolves name question: Hindsight = Vectorize. Differentiation is NARROW and specific: cross-vendor-live + canon-with-attribution + local-first. Marketing must draw exactly these lines.
