structured project memory

Resume any project
in minutes, not hours.

Come back after days or weeks away and instantly know what you were doing, why you made each decision, and what to do next — instead of re-reading old code for 30 minutes.

Your code survives. Your thinking doesn't. ContextOS keeps the thinking too.

Ship v9: dual regime detection (short + long windows) with expectancy-based position sizing.

Decision Log✓ decision made

Dropped DexScreener from entry logic — quality score, buy/sell ratio, and regime filter alone gave a cleaner signal.

✦ AI Briefing✓ last session

Best session so far: 66.7% win rate, +0.1403 SOL. Partial take-profits and the don't-chase filter are both paying off. Next: design the dual-regime window split.

⚡ Next Action✓ next step

Design dual regime architecture (short + long windows) before writing any code.

v8 live at ~/project/momentumsniper. Last: 66.7% WR, +0.1403 SOL. v9 plan: dual regime, expectancy sizing.

Code lives in GitHub.

Todos live in GitHub Issues.

Context lives in ContextOS.

A forgotten project,
instantly understandable.

Built because I kept wasting 20–30 minutes every time I returned to an old project.

Without ContextOS

30 minutes re-reading old code, scrolling chat history, and trying to remember why you made that decision.

With ContextOS

Open the project, read one AI briefing, and start working. Where you left off, why, and what's next — in 30 seconds.

why not just use what I already have

Notion, GitHub, and ChatGPT
already do part of this.

Git remembers your code. ChatGPT remembers conversations. Notion remembers notes.
ContextOS remembers your project.

How ContextOS Works

1

Start a project

Give it a mission and a goal — the one thing this project is trying to do.

2

Work, then log it

After each session, note what happened in seconds. Not a journal entry.

3

Leave for two weeks

Life happens. Client work, another project, a break. The memory doesn't fade.

4

Come back to a briefing

ContextOS reads everything you logged — plus your GitHub repo if connected — and writes where things stand.

5

Resume in 30 seconds

Read the briefing, see your next action, start working. No archaeology.

why this exists

I run five projects at once — a trading bot, a Telegram bot, a SaaS, client work, and this.

No notes app fixed the switching cost, because notes depend on me remembering to write them. ContextOS is the fix I built for myself. Every screenshot on this page is my real workload, not demo data.

Monday

Deep in the trading bot — regime detection, position sizing, the whole mental model loaded.

Tuesday

Client work pulls you away. Different codebase, different logic, different everything.

Three weeks later

Open the trading bot again. “Which version was live? Why did I drop that library?”

ContextOS

Read one briefing. Know exactly what happened, why, and what's next. Start working.

faq

Common questions.

ContextOS is where a project's memory lives — sessions, decisions, resources, ideas, and an AI-written briefing for every project you run. Open one and know exactly where you left off, without re-reading old code or chat history.

Notion and Obsidian are blank pages — you build the structure yourself and have to remember to keep it updated. ContextOS is a fixed structure built specifically for resuming projects: sessions, decisions, ideas, and next actions are already the right shape, and the AI briefing writes itself from what you've logged.

GitHub tells you what changed in the repository. ContextOS tells you what changed in your project — and what to do next. Code and commits live in GitHub; the reasoning behind decisions, the idea you never wrote down, and your next action live here. You can also connect a repo, and your AI briefings will include commits, merged PRs, and open issues since your last session.

No, and yes. Logging sessions, decisions, ideas, and resources works fully without AI. The AI briefing is an optional layer on top — it reads what you've already stored and summarizes it. It never replaces the underlying record, so nothing is lost if you skip it.

Developers, founders, and researchers who run more than one project and lose time re-orienting every time they switch. If you've ever opened an old project and thought "wait, where was I?" — this is built for that exact moment.

Today, ContextOS is built around one owner per project logging its memory — it's not yet a shared multiplayer workspace. Teams get the most value when one person (a lead or founder) keeps the project memory that the rest of the team gets briefed from.

Free includes 5 projects, unlimited sessions, decisions, ideas, and resources, plus 5 AI resume briefings per month.

ContextOS Pro is billed in crypto — USDT on the network of your choice (Solana, BSC, Tron, and more). No credit card required.

You can export everything — sessions, decisions, ideas, resources — to Markdown at any time. Your project memory was never meant to be locked in.

Not yet — it's on the roadmap. Today, ContextOS works through the web app and optional GitHub integration.
