Your AI works at a small focus window
Everything it's thinking about — your messages, its replies, files it opened — has to fit on one window. The window has a fixed size.
Most AI tools erase old context to make room. LCM-X keeps every moment in a permanent, searchable memory — so agents and robots can recall the exact detail again.
Help me plan a week in Japan in April — Tokyo, then Kyoto.
Drafted 7 days: 3 in Tokyo, 4 in Kyoto, with the bullet train between.
Keep the whole trip under $3,000, flights included.
Rebalanced: mid-range hotels, one splurge dinner — total $2,840.

Everything it's thinking about — your messages, its replies, files it opened — has to fit on one window. The window has a fixed size.
Long chats, big files and research sessions pile up fast. Something has to be cleared off before work can continue.
The old pages get squeezed into a short summary and erased. Whatever the note missed — a number, a name, an instruction — is gone for good.

Each page goes into memory as it arrives. The window stays small; the originals stay safe.
What you just said is always kept in full, right in front of the AI. Only older pages are ever tidied away.
When the window gets full, LCM-X writes a summary note for the window and preserves the original pages in memory. Nothing is erased.
Every note points back to the exact pages it summarises, so the AI can always look it up and read the original. The cycle repeats quietly, keeping the window clear.
Several notes become one folder summary, like chapters in a book. Hours or days of work stay findable in seconds.
Minutes ago gets full notes, hours ago gets a chapter summary, days ago gets the headline — always with the original a step away. Small window, nothing lost.

Before pulling anything out, the AI can peek at what's inside a memory — without cluttering the window.
It searches every page and every note at once, and understands word forms — 'kayaking' finds 'kayaks'.
A small assistant opens the right memories and reads the originals, so the main window stays clear.
The AI answers with the precise detail from hours ago — quoted from the original, not guessed from a summary.
questions answered right about a long conversation, vs Hermes' built-in memory
facts from the middle of long documents now kept in summaries
search accuracy, up from 84.7% — 'kayaking' now finds 'kayaks'
messages ever thrown away. Everything stays searchable.
Every conversation, every file it read, all searchable by meaning or exact words.
Not a fuzzy recap — the original sentence, number or instruction, quoted back.
Nothing is deleted to make room. Long projects stay whole, for days or weeks.
LCM-X is a free, open-source add-on for the Hermes AI agent.
