Search that feels like memory

Skillsync searches your coding agents’ session history before each prompt. No index, no embeddings, no setup

The midwit meme. Both ends of the bell curve say: look at session history. The middle cries over embeddings, a vector DB, RAG, a knowledge graph, fact extraction, memory decay, temporal reasoning, continual learning and dreaming.

Fast. Serverless. Complete.Choose any three

every session, searched on every promptnothing saved ahead of time, nothing to set up

A prompt is checked against every past session; two of them match and come back as a recollection.

    it decides

    Skillsync checks whether your past work matters here. If it doesn’t, it stays out of the way.

    it reads everything

    Every session in the folder, or all of them when it needs to, read for what you did, decided and found.

    your agent remembers

    A short recollection, with sources, arrives with your prompt. Your agent builds on it instead of starting over.

    ⏺ From 2 past sessions

search from anywhere

press ⌥⇧Space over any app,
every session is right there

Search drops out of the notch over whatever you’re doing. Open a session, continue it in its agent, or copy just the part you need.

continue in any agent

Resume a session right where it stopped, or carry it into the coding agent of your choice. The whole conversation comes along.

private by default

Sessions are read and indexed on your Mac and never uploaded unless you share one. Smart search runs with zero data retention.

ask in plain words

Search covers prompts, replies, reasoning, commands and file paths as you type. Press ⏎ and smart search answers with the sessions cited.

every skill, one place

See the skills each of your agents has, switch them on or off per agent, and find the sessions that used them.

workspaces

your best work, sharedsearch your team’s sessions like your own

Make a workspace for your team. Share a session with a link or by name, keep skills in one place, and type @ to search everything your team has shared. Your own sessions stay private until you share them.

private until you share

Everything starts in Private, on your Mac. Pick which sessions and skills your team gets to see.

share a session

Send anyone a link, or share with a teammate by username or email. They read it as the whole conversation.

one skill library

Share the skills that work with the workspace, tagged the way your team sorts them, in every agent.

Then run skl init. On a remote server, sign in with skl login --device.
