Episodic memory · for Claude Code

Your AI forgets.
Hydrate remembers.

Claude Code starts each session with a blank mind. Hydrate captures what was built, decided, and named - then quietly injects it into the next session. No prompt engineering. No screenshots of previous chats. Just context that works. 

curl -fsSL gethydrate.dev/install | sh

Apple Silicon and Intel both supported - the installer picks the right binary.

Tokenmaxxing isn't productivity - it's expensive churn. Hydrate measures cost per shipped session, not tokens spent. Read the receipts →

What kind of developer are you?

Hydrate's pitch lands differently depending on how you ship. Pick the audience that fits and we'll skip the parts that don't apply.

Solo developer

Buy back the days Claude forgot.

You ship alone. Half your week is re-explaining the architecture to a forgetful model. Hydrate buys those days back. Free for up to 2 active projects, forever.

Free tier. No credit card. Go →
Team lead

Juniors ship at senior quality.

Pin the architecture once on Opus. hydrate sync propagates it to every teammate's CLAUDE.md. Juniors on Haiku inherit Opus-tier discipline at ~10% of the cost.

Engineering manager

Stop paying for tokens. Start paying for shipped work.

The Hybrid cell ships 7-of-7 at $0.20 per shipped session - 12% of raw-Opus cost. Self-host, SSO, SOC 2, air-gap if you need it. The empirical answer to tokenmaxxing.

What changes

The difference is execution, not intelligence.

Models don't get smarter with Hydrate. They get context. That's usually enough.

without Hydrate 
$ claude "add a dark mode toggle"

Haiku: What should the default
 colour scheme be?
Haiku: What do you mean by
 "toggle" - a button? switch?
Haiku: Which pages should be
 affected?

with Hydrate

Haiku: edits src/styles/globals.css
Haiku: edits src/components/Nav.tsx
Haiku: Done. Toggle wired to

One intervention · four outcomes

Reliability is the unlock. Cost savings follow.

Hydrate isn't a uniform speed-up. Each model has a different failure mode without context - refusal, drift, re-exploration, ceiling-hitting - and Hydrate removes all four. Cost reduction is the measurable consequence; reliability is the primary change.

Haiku 4.5 reliability unlock
before
2/7 sessions ship. Asks clarifying questions instead of building.
with Hydrate
7/7 sessions ship. Every prompt executed. Cost per shipped session: $0.15 vs $0.30.
Sonnet 4.6 neutral stabiliser
before
Builds cleanly, 7/7 sessions. The polish ceiling.
with Hydrate
Builds cleanly with modest efficiency gain. −14% cost, zero regression.
Opus 4.7 (simple) cost reducer
before
Re-explores workspace every session.
with Hydrate
Skips re-exploration, produces same output. 57% less cost for identical work.
Opus 4.7 (complex) capability unlock
before
3/7 sessions refuse with "need clarification". One $3.88 ack.
with Hydrate
6/7 sessions build, converting refusals into full features. The $3.88 ack becomes a complete docs site.
Hybrid - Sonnet s1 → Haiku s2+ architecture propagation
before
n/a - this is a workflow, not a model.
with Hydrate
Sonnet-tier design propagates to Haiku via memory. $1.41 total, $0.20 per shipped session (45% of pure Sonnet).

How it works

Three quiet pieces.

01

Hooks

Hydrate installs two Claude Code hooks - UserPromptSubmit and Stop. They're invisible to you. They capture each session's prompt, decisions, and output.

02

Facts

Between sessions, an extractor pulls concrete facts - "pricing tiers are Free/Pro/Team", "accent colour is #89b4fa" - and stores them scoped to your project.

03

Dashboard

A local dashboard at localhost:8089/dashboard shows your spend, cache ratio, and facts per project. Nothing ever leaves your machine - Free, Pro, or Team.

Built with Claude Code

This site is its own first data point.

Hydrate reads Claude Code's local transcripts and adds them up. These are the real numbers for the work that produced gethydrate.dev - no rounding, no cherry-picking.
