Noise piles up
Tool output, file dumps and retries crowd the context window. The parts that matter get buried.
Context engineering for AI agents
Say more with
fewer tokens.
Long AI sessions fill up with noise. Pithly remembers what matters across sessions and gives your model only the context it needs. Sharper answers, a smaller bill.
The problem
Long chats get expensive
and forgetful.
Decisions get lost
What you agreed an hour ago, or yesterday, falls out of the window. The agent asks again or guesses.
You pay for every re-read
Each turn sends the whole history again. Bigger context means a bigger bill, not a better answer.
How it works
Remember. Recall. Fit.
-
Remember
After each turn, Pithly keeps the facts, decisions and code references worth keeping, in a memory that belongs to your project.
-
Recall
When you ask something, it searches that memory by meaning and by exact names, including function and file names, then picks the few notes that answer it.
-
Fit
Your model gets a short, focused brief instead of the whole history. Less to read, less to pay for, less to get wrong.
Products
One memory. Two ways in.
For developers
Pithly for Claude Code
A plug-in that works quietly inside Claude Code. Every session starts with the right context from earlier work, so long coding tasks stay on track.
- Memory per project
- Finds code by name, not just by meaning
- Uses your own model key
For builders · preview
Pithly API
Give your own agents and AI apps long-term memory. Separate, walled memory for every app and every user.
- Clients for LangGraph, LangChain, CrewAI and Google ADK
- Walled memory per app and per user
- Simple HTTP API
Principles
Built on three rules.
Accuracy first
We never cut a token that changes the answer. Savings come second to getting it right.
Your data, walled
Memory is kept apart per project, per app and per user. Nothing is shared between them.
Measured, not guessed
Every change is tested on real long-session benchmarks before it ships.
Early access
Free during the beta.
Pithly is in private beta with a small group of developers. Tell us what you build and we'll get you in.
