# Hindsight

5 Hacker News commenters recommended Hindsight and 2 criticized it, November 2025 to November 2026. It was recommended in 4 of 13 months.

**Verdict:** People recommend Hindsight as a memory layer for AI agents that can cut token use over time and replace hand-kept memory files. The caveat is that stored memories were sometimes ignored by agents after a while.

## Why people recommend it

- Lowers token usage over time (1 comments): "if you do similar stuff often your token usage will drop after awhile of using a memory subsystem like hindsight or honcho" ([source](https://news.ycombinator.com/item?id=48081531))
- Promising for building agents (1 comments): "it looks very promising in terms of capabilities to address many of my own issues with building out agents" ([source](https://news.ycombinator.com/item?id=46289903))
- Helps front-load early context (1 comments): "should def help with that early front loading of context" ([source](https://news.ycombinator.com/item?id=48936915))
- Replaces MEMORY.md file (1 comments): "I'm also using Hindsight instead of the MEMORY.md" ([source](https://news.ycombinator.com/item?id=48892434))

## What people warn about

- Stored memories get ignored later (1 comments): "were simply ignored by agents after a while" ([source](https://news.ycombinator.com/item?id=49951745))
