## Taglines

- two agents. one works. **one doubts**
- your agent doesn't know it's **wrong**
- doubt as a **service**
- never fly **solo**
- ask nina how she works. she'll **tell you**
- you can't watch them all. **nina can**

## Why Nina

Single agents fly solo. There is no one watching. No one to raise an **** **eyebrow** when things go sideways.

The doubt-agent operates **outside** the context window, the only **unbiased** place.

The doubt-agent helps the main-agent **succeed**, restarting it if it gets stuck, guiding it if it gets lost, and calling it out when it makes **bad choices** .

You could build your own orchestration, wire up agents, manage contexts, manage state, handle signals, tune interventions, maintain it all as prompts evolve, and refine it over time in production.

Or you could download Nina and get back to work.

## Documentation

### Who is Nina?

Nina is a steerable LLM agent that self-supervises:
- The main-agent does the work.
- The doubt-agent steers the main-agent.
- The stop-agent restarts the doubt-agent.

codex working with opus supervising: `nina run -m codex -d opus`

gpt5 working unsupervised: `nina run -m gpt5`

### What can Nina do?

Nina has three modes of operation:

Ask a question: `echo "mass of the sun?" | nina ask -m gpt5`

Edit files: `echo "add error handling" | nina arch -m opus src/*.py`

Work unsupervised: `nina run -m codex`

Work self-supervised: `nina run -m codex -d glm`

### Why should I use this?

You shouldn't.

You should fork one of the many sub-500 LOC agent implementations on GitHub and build something bespoke. This will always fit better, and is very fun.

Nina has no secrets. She will happily explain how she works and what her prompts are. The self-supervision system manifests naturally, and you would likely discover it on your own.

The primary problem self-supervision solves is that due to their RL training, LLMs are biased toward their own work in a given context window. They are too close to it. All you have to do is step outside of that context window and the bias is gone. You see this when you stop a session, start it again, and ask the LLM to review its past work.

The main-agent has the largest system prompt and most tools, it does the work.

The doubt-agent has a smaller system prompt and fewer tools. It monitors, provides feedback, restarts the main-agent as needed, and intervenes if anything bad is happening.

The stop-agent is not even an agent. It's a single API request that triggers when the doubt-agent exits, to determine if the doubt-agent should be restarted.

Self-supervision is the buddy system. Life is better with a friend. The life of an agent is no different. Three seems to be the magic number. Large, medium, small.

If, for whatever reason, you don't have time to craft a bespoke agent, and then more time to refine it in production, you should use Nina.

### Can I use Nina on my phone?

Yes. `nina ops` launches a web ui.

Generate a key with `nina auth ops-genkey`.

Then use WireGuard, Tailscale, or similar to access `https://0.0.0.0:7444` on your computer.

### What is self-supervision?

With self-supervision Nina is able to:
- Stay on task.
- Recover from mistakes.
- Work through unlimited context windows.

If you want to work interactively with Nina, leave her unsupersived.

If you want Nina to work autonomously, let her self-supervise.

### Can I supervise Nina?

You can supervise Nina with or without self-supervision.

All session information is stored in: `.runs/`

`ctrl-c` while Nina is running will interrupt her and return to a prompt.

`ctrl-c` at a prompt will exit the session.

You can steer Nina without interrupting her by writing to: `SUGGEST.md`

You can prompt Nina non-interactively by writing to `TASK.md` and sending:
- `SIGHUP` to interrupt and continue context.
- `SIGUSR1` to interrupt and reset context.

Nina's pid is written in: `.runs/pid`

When Nina is self-supervising, you can monitor and steer the doubt-agent as well. It is another Nina instance operating out of a tempdir written in: `.runs/doubt_agent`

Tail the doubt-agent's log with: `tail -f $(cat .runs/doubt_agent | head -n1)/.runs/log`

### What models are supported?

Nina can use any combination of these models:
- opus
- sonnet
- gemini
- gpt5
- gpt5-flex
- codex
- glm
- minimax

### What is the state model?

Nina uses files to track state:

`NINA.md`: project notes (durable)
`PRD.md`: project specification (durable)

`TODO.md`: work status, discoveries, decisions (ephemeral)
`TASK.md`: prompt read on startup or on signal (ephemeral)
`SUGGEST.md`: steer Nina while she's running (ephemeral)

`.runs/`: contains session artifacts (ephemeral):
- `.runs/log` - terminal output
- `.runs/prompts` - user and self-supervised prompts
- `.runs/tools/` - tool call history
- `.runs/message/` - raw API messages
- `.runs/pid` - Nina's process ID
- `.runs/doubt` - doubt injection audit trail
- `.runs/doubt_agent` - doubt-agent tempdir (when self-supervising)

### What is the privacy model?

Nina runs entirely on your machine:
- API calls go directly from your machine to the providers you choose.
- Your prompts, code, and responses never pass through Ninagent servers.

Individual Plan binaries do not communicate with Ninagent servers after download.

All other plans exchange a license identifier for a signed timestamp once weekly.

### What is the licensing model?

Individual:
- Perpetual license per binary downloaded while subscribed.
- Binaries work forever, even after subscription ends.
- No license validation after download.

Business:
- Subscription site license for teams.
- Requires periodic license validation.

Enterprise:
- Subscription site license with SaaS use rights.
- Requires periodic license validation.

### Will pricing increase?

For Individual plans, your subscription price is locked in from your first month and stays the same as long as you maintain a continuous monthly subscription.

Business and Enterprise plan prices may change with reasonable notice and regard to custom contracts.

### What are the system requirements?

Linux, macOS, or WSL.

### Does Nina support MCP?

No. Use a CLI instead.

If you need a specific MCP server, Nina can help you wrap it in a CLI.

### How do I configure syntax highlighting?

Set color scheme via env var: `NINA_SYNTAX=dracula`

Default: `monokai`

Disable highlighting: `NO_COLOR=1`

Dark themes: `monokai`, `dracula`, `doom-one`, `fruity`, `nord`, `solarized-dark`, `vim`

Light themes: `github`, `solarized-light`, `xcode`, `vs`, `autumn`, `friendly`

More themes: `github.com/alecthomas/chroma`

### How do I get help?

Email [hi@ninagent.com](mailto:hi@ninagent.com) or ask Nina in [Discord](https://better.game/discord) where she is busy building a [better game](https://better.game).

5.1 License. Subject to your compliance with these Terms and payment of applicable fees
(after any free trial period), we grant you a limited, non-exclusive, non-transferable,
non-sublicensable license to install and use the Software for your internal personal or
business purposes. All licenses granted under these Terms are non-transferable and
non-sublicensable.

5.2 Individual Plan - Perpetual License. If you purchase an Individual Plan:
(a) You receive a perpetual, non-transferable license to any Software binaries you download
while maintaining a valid paid subscription.
(b) "Perpetual" means you may continue using those specific downloaded binaries indefinitely,
even after your subscription ends, subject to continued compliance with these Terms.
(c) Updates and new versions released after your subscription ends are not included; you must
maintain an active subscription to download new binaries.
(d) Individual Plan binaries do not require license validation and do not communicate with
Ninagent servers after download.

5.3 Business and Enterprise Plans - Subscription License. If you purchase a Business or
Enterprise Plan:
(a) You receive a temporary, non-transferable license to the Software (binary and/or source
code, depending on your plan) that is valid only while you maintain a valid paid subscription.

(b) A single seat may install and use the Software on multiple devices that are owned or
controlled by that seat, provided the seat is the primary user.

5.5 No implied rights. All rights not expressly granted are reserved.

6. RESTRICTIONS

6.1 You may not (except to the extent prohibited by applicable law):
(a) copy, modify, adapt, translate, or create derivative works of the Software (except as
expressly permitted for source-code access plans);
(b) reverse engineer, decompile, disassemble, or otherwise attempt to derive the source code
of the Software;
(c) rent, lease, lend, resell, sublicense, distribute, or otherwise make the Software
available to third parties on a service bureau, timesharing, managed services, or software
as a service (SaaS) basis, or offer the Software to external customers, unless expressly
permitted by a custom enterprise license;
(d) bypass, disable, tamper with, or circumvent license enforcement, access controls,
or security mechanisms (including the Validation Service);
(e) remove or alter proprietary notices;

features. You are responsible for maintaining backups and version control appropriate to your
workflow.

7.2 Support. Unless you purchase a support plan or we agree otherwise in writing, support
is provided "as available" and not guaranteed.

8. LICENSE VALIDATION AND OFFLINE USE

8.1 Validation requirement. License validation applies to free trial users and Business and
Enterprise Plans. By default, the Software attempts validation approximately once every
seven (7) days. Individual Plan binaries do not perform validation and do not communicate
with Ninagent servers after download.

8.2 Data sent for validation. When validating, the Software may send:
- a license identifier (not the full License Key),
- timestamp,
- IP address (from which the request originates),
- Software version and OS/platform,
- and other minimal request metadata necessary to operate the Validation Service.

8.3 Grace period. For plans that validate, the Software caches successful validations locally.
Validation must succeed at least once every fourteen (14) days. If validation cannot be completed within fourteen (14)
days of the last successful validation (due to network issues, service unavailability, or other
reasons), the Software may reduce functionality or stop working until validation succeeds.

8.4 No guarantee of uninterrupted validation. We do not guarantee uninterrupted availability
of the Validation Service for plans that require it. If we permanently discontinue the
Validation Service, we will release a version of the Software that does not require validation,
or provide equivalent relief.

9. LOCAL CHANGES AND COMMANDS - IMPORTANT SAFETY WARNING

9.1 Autonomous command execution. Ninagent is a command-line coding agent that operates
autonomously. It executes shell commands, runs arbitrary code, installs dependencies,
creates/modifies/deletes files, modifies system configuration, accesses networks, and
performs any other operation that can be performed via shell commands - ALL WITHOUT HUMAN
REVIEW OR APPROVAL BY DEFAULT.

9.2 Potential for catastrophic damage. The Software can execute ANY command, including but
not limited to destructive commands such as "rm -rf /", commands that modify or destroy
data, commands that affect network configuration, commands that expose sensitive information,
and commands that could render systems inoperable. While the Software and underlying AI models
are designed with safety in mind, NO GUARANTEE OF SAFE BEHAVIOR IS PROVIDED OR IMPLIED.

9.3 Operator responsibility for sandboxing. It is YOUR sole responsibility to decide whether
to run the Software in a sandboxed environment (container, virtual machine, restricted user
account, network isolation, etc.) or unrestricted. We STRONGLY RECOMMEND running the Software
in an isolated environment where damage is contained and recoverable.

9.4 Backups required. You MUST maintain comprehensive backups before using the Software.
The Software may modify or delete any files accessible to it as part of normal operation.

9.5 Full assumption of risk. BY USING THE SOFTWARE, YOU ACKNOWLEDGE THAT YOU UNDERSTAND
THESE RISKS AND YOU ASSUME FULL RESPONSIBILITY AND LIABILITY FOR ANY AND ALL CONSEQUENCES
OF USING THE SOFTWARE, INCLUDING BUT NOT LIMITED TO DATA LOSS, SYSTEM DAMAGE, SECURITY
BREACHES, NETWORK DISRUPTION, FINANCIAL LOSS, AND ANY OTHER DIRECT OR INDIRECT DAMAGES.
Ninagent and its operators bear no responsibility for damage caused by the Software.

(a) evaluating the security and trustworthiness of any third-party integrations;
(b) complying with the terms and licenses of third-party integrations;
(c) any consequences of using third-party integrations with the Software.

10.3 No warranty for integrations. We provide no warranty or support for third-party
integrations and are not liable for any issues arising from their use.

11. THIRD-PARTY AI PROVIDERS

11.1 Your relationship with Third-Party AI Providers. Your use of Third-Party AI Providers is
governed solely by your agreements with those providers. You are responsible for:
(a) obtaining and maintaining valid API keys/accounts with Third-Party AI Providers;
(b) paying all fees charged by Third-Party AI Providers, including usage-based API charges;
(c) complying with their terms, usage policies, and applicable laws;
(d) ensuring you have rights to submit any prompts/content to them; and
(e) any cloud, compute, network, or other third-party service costs incurred through your use of the Software or Third-Party AI Providers.

11.2 We do not receive your keys, prompts, or responses. We do not collect, store, or process
your Third-Party AI Provider API keys, your prompts, or model responses through our servers.
(If you voluntarily send logs or examples to support, that information will be handled under the
Privacy Policy.)

11.3 No responsibility for Third-Party AI Providers. We are not responsible for Third-Party AI
Providers or any third-party services, including their availability, outputs, policies, or data
practices.

trial. The free trial allows you to evaluate the Software before purchasing. You must stop using
the Software after the trial ends unless you purchase a subscription.

15.2 Trial extensions. If you experience technical issues during your free trial that prevent
proper evaluation, contact support. We may extend your trial period at our discretion.

15.3 Fees. After the free trial, continued use requires a paid subscription. Prices and plan
terms are presented at the time you purchase. Merchant of record: https://polar.sh.

15.4 Auto-renewal. Subscriptions automatically renew until you cancel. You authorize us (and
our payment processor) to charge your payment method on a recurring basis until you cancel.

15.5 Cancellation. You may cancel future renewals through your account/billing portal or by
contacting support. Cancellation stops future charges but does not provide a refund for the
current billing period.

15.6 No refunds. Because we offer a free trial period that allows you to fully evaluate the
Software before purchasing, all payments are non-refundable except where required by applicable
law. If you have concerns about the Software, please use the free trial to evaluate it before
purchasing.

15.7 Taxes. Fees are exclusive of taxes unless stated otherwise. You are responsible for
applicable taxes.

15.8 Discontinuation. If we discontinue the paid Services, we will provide reasonable notice.
For Business/Enterprise subscribers with prepaid unused subscription time, we will provide an

arising out of or relating to these Terms, the Software, or Services will be resolved by binding,

in-person hearing is required, it will occur in a location determined under AAA rules, taking into
account your residence and ability to travel.

free trials and Business and Enterprise plans.
- Individual Plan binaries do not communicate with Ninagent servers after download.

(b) Support communications:
- If you email us or contact support, we will collect the information you provide in the message

IMPORTANT: If you paste logs, configuration, prompts, or code into a support ticket/email, we
will receive that information because you provided it to us.

For free trials and Business and Enterprise plans, when the Software validates your license
(approximately every 7 days), our servers may receive:
- License identifier (not the full License Key)

- IP address
- Software version and OS/platform
- Standard server log metadata (e.g., request headers, response codes) used for reliability and security

We do NOT collect device fingerprints, hardware identifiers, or usage telemetry beyond license validation.
Individual Plan binaries do not validate and do not communicate with Ninagent servers after download.
