Symbiotic Ai
An open-source, model-agnostic context system that keeps your AI agent's memory in four Markdown files you own.
If a chat forgetting your project for the fourth time sent you looking, the two-minute demo is the cheapest way to test whether persistent context actually helps you — it sends your messages to their API, so don't type anything private. The 4-file split holds up in practice: SOUL and USER rarely change while NOW churns, and plain Markdown means you can diff, commit and carry it to another model. Compare it to Mem0 or Letta and you're choosing hand-maintained text over automatic memory. Worth it only if you'll actually edit NOW.md.

Skip Symbiotic AI if you want memory that updates itself with no manual editing, or need a dashboard and shared team workspaces rather than Markdown files you maintain by hand.
You maintain NOW.md yourself — nothing outside the demo rewrites it, so the real cost is the minutes you spend curating context each session.
The system itself is free and open source, so the real cost sits in the model subscription you already pay for. That makes it cheaper than a managed memory layer like Mem0 or Letta, which charge for a hosted memory tier. It fits individual developers and power users running one or two models; teams wanting a managed, shared memory service should look at the hosted options instead.

About Symbiotic Ai
Symbiotic AI is an open-source framework that takes an AI agent's context out of a vendor's memory layer and puts it in four plain Markdown files in a folder you control. SOUL.md holds the agent's personality and stance, USER.md captures your psychology, patterns and goals in your own words, AGENTS.md carries rules, protocols and anti-patterns. Those three stay stable, so the agent's character survives between sessions. NOW.md is the volatile one — live tasks, current state and a running memory log rewritten as work moves. Your agent reads all four at the start of every session. Setup splits by platform: on Claude Code or opencode a single curl script installs the full 4-file system with bundled skills and commands; everywhere else there's no install at all — you paste prewritten instruction blocks into ChatGPT custom instructions, a Claude Project, or a Gemini Gem, with a dedicated guide for each. A discovery generator walks you through 8 scenarios and outputs all four files personalised to how you think and work, generated locally and downloaded to your device. A live demo runs about two minutes: pick an archetype, chat, and export a workspace with your own Today and Commitments files. The public repo (lout33/symbiotic-ai) shows 738+ stars and 77+ forks, with long-form essays published alongside the code. Set against managed memory layers like Mem0 or Letta, the trade is explicit: you give up automatic, self-updating memory and get ownership, editability and portability in return.
Behind the Verdict
The design decision that matters here is the split between stable and volatile context. SOUL.md and USER.md rarely change — they hold personality, stance, and your own description of how you work. AGENTS.md holds the rules, protocols and anti-patterns the agent should follow. NOW.md is rewritten as work moves, holding live tasks and a memory log. Because those four are separate files, your agent's personality doesn't degrade as tasks churn, which is the failure mode you hit when everything lives in one chat history. The second decision is that it's all plain Markdown in version control. You can read it in any editor, diff a change to how your agent behaves, revert it, fork it, and carry it to a different model. That's the actual product: portability. The comparison the vendor invites against managed memory layers like Mem0 or Letta is fair — you're trading automatic, self-updating memory for ownership and editability. If you won't curate the files, you get less than the managed layers give you. Onboarding is deliberately uneven. On Claude Code or opencode, one curl script installs the full 4-file system with bundled skills and commands. On ChatGPT, Claude web and Gemini there's nothing to install: you paste instruction blocks, with separate guides for ChatGPT custom instructions, Claude Project Knowledge (SOUL.md and USER.md as files) and Gemini Gems. Two honest caveats. The Discovery profile generator runs locally and downloads to your device, but the live workspace demo sends messages to their API to respond — it isn't fully local. And there's no dedicated app UI; the files themselves are the interface, so you need to be comfortable maintaining Markdown by hand. The public material documents the setup guides, the demo and the repo, and doesn't cover sync, security or team collaboration, so don't assume them.

Real-world workflow fit
Concrete scenarios for the personas Symbiotic Ai actually fits — and what changes day-one when you adopt it.
You run the curl install script, then answer the 8-scenario discovery generator to produce SOUL, USER, AGENTS and NOW local to your machine.
Outcome: Your agent reads all four files at the start of each session, so personality and rules persist while you rewrite NOW.md as tasks move.
You paste the About Me block into custom instructions and the agent instructions into the response field — or into a Gemini Gem — without installing anything.
Outcome: A new chat already knows your psychology and how you want to be challenged, in about two minutes of pasting.
You export the four Markdown files and commit them to Git, then point a different model at the same folder.
Outcome: The agent's character survives the switch, and every change to its behavior is diffable and revertible.
Use Cases
- Set up a persistent assistant that remembers your goals and personality across sessions via SOUL.md and USER.md.
- Keep long-running projects on track by updating NOW.md with live tasks and logging progress each session.
- Carry your context files to a different model without losing your agent's personality or rules.
- Export your full context as Markdown to share, back up, or hand-edit in any text editor.
- Generate a personalised 4-file profile in about five minutes instead of writing instructions from scratch.
- Install the system on Claude Code or opencode in roughly a minute via the curl script.
- Run the two-minute live demo to see whether persistent context fits how you work.
- Version your agent's identity in Git so behaviour changes are diffable and revertible.
Limitations
- Symbiotic AI is a four-file Markdown context system, not an AI model, so getting started means either running the curl install script on Claude Code or opencode, or pasting instructions into ChatGPT, Claude web or Gemini.
- You maintain the files — nothing outside the demo writes NOW.md for you — so it rewards people who will actually curate context and punishes those who won't.
- Discovery profiles generate locally and download to your device, but the live workspace demo sends messages to the vendor's API to generate responses.
- There is no dedicated app UI.
- The public material documents setup guides, the demo and the open-source repo, but not security, sync or team collaboration capabilities.

Where the pricing makes sense
The company stage and team size where Symbiotic Ai's pricing actually pencils out — and where peers do it cheaper.
The system itself is free and open source, so the real cost sits in the model subscription you already pay for. That makes it cheaper than a managed memory layer like Mem0 or Letta, which charge for a hosted memory tier. It fits individual developers and power users running one or two models; teams wanting a managed, shared memory service should look at the hosted options instead.
Setup time & first value
How long it actually takes to get something useful out of Symbiotic Ai — broken out by persona, not the marketing-page minute.
Claude Code / opencode: about 1 minute via the curl script. ChatGPT: about 2 minutes of pasting into custom instructions. Claude web: about 3 minutes to create a Project and add SOUL.md and USER.md as Project Knowledge. Gemini: about 2 minutes to build a Gem. The discovery generator takes roughly 5 minutes if you want personalised files first.
Switching to or from Symbiotic Ai
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From a single long ChatGPT conversation: export the relevant context and split it into SOUL, USER, AGENTS and NOW by hand.
- →From Claude Projects free-form instructions: replace the blob with SOUL.md and USER.md as Project Knowledge plus pasted agent instructions.
- →From Mem0 or Letta: copy your stored profile and rules out into the four Markdown files, accepting manual updates going forward.
