RightNow AI is a YC-backed GPU research lab and software company. Its flagship product is RightNow Agent, the fastest coding agent harness in the world. It also builds the RightNow editor and Forge.

What is RightNow Agent?

RightNow Agent is the fastest coding agent harness in the world, a Rust terminal CLI built for one thing: speed. On the measured Windows path, a warm daemon opens a session in 105 to 115 ms.

Which NVIDIA GPUs does the RightNow editor support?

The RightNow editor supports all NVIDIA GPUs with CUDA Toolkit 11.0-12.5, including GeForce RTX 40/30/20 series, GTX 16/10 series, Quadro RTX, Tesla, A100, and H100.

How much does RightNow AI cost?

RightNow AI is free to use with unlimited profiling and benchmarking. RightNow Pro costs $20 per month and adds GPU emulator access (50+ GPUs), multi-GPU comparison, and 1,000 AI credits per month.

What CUDA development workflow does the RightNow editor support?

The RightNow editor supports CUDA development workflows that combine editing, profiling, emulation, remote GPU execution, and benchmarked performance analysis.

Can I use the RightNow editor on macOS?

Yes, the RightNow editor is available on macOS (Apple Silicon and Intel). Mac users can use remote GPUs for free or our built-in GPU emulator for CUDA profiling.

Headless Mode

RightNow Agent runs one prompt without the interactive UI when you pass -p, --single, or --print. It executes approved local tools, writes the result to standard output, and exits.

One-shot usage

powershell

$env:RIGHTNOW_API_KEY = "<your key>"
.\rightnow.ps1 -p "Review this workspace for broken imports"
.\rightnow.ps1 --print "Summarize the API" --cwd C:\work\project
.\rightnow.ps1 -m runinfra -p "Explain the failing test"

The same flags can be passed to rightnow-pager.exe. The shipped configuration uses RunInfra as the default provider.

Core options

Option	What it does
-p, --single, --print <PROMPT>	Send one prompt, print the result, and exit.
--cwd <PATH>	Use PATH as the working directory.
-m, --model <MODEL>	Select a configured model entry.
--output-format <FORMAT>	Choose plain, json, streaming-json, or streaming-messages-json.
--json-schema <SCHEMA>	Constrain the model to a JSON Schema and imply JSON output.
--always-approve	Approve offered tool permissions automatically.
--yolo	Alias for --always-approve.
--dangerously-skip-permissions	Alias for --always-approve.

Output formats

Format	Use
plain	Human-readable final text. This is the default.
json	One final JSON object with response, session, stop, and available usage fields.
streaming-json	Newline-delimited RightNow events for text, tools, usage, plans, completion, and errors.
streaming-messages-json	Newline-delimited Messages API style frames, ending with a result record.

powershell

.\rightnow.ps1 -p "List the changed modules" --output-format json
.\rightnow.ps1 -p "Return the package name" --json-schema '{"type":"object","properties":{"package":{"type":"string"}},"required":["package"]}'

Permission warning

Always-approve is not a sandbox

--always-approve, --yolo, and --dangerously-skip-permissions all auto-approve offered tool executions. Use them only in a trusted workspace and host environment. Deny rules, hooks, and administrator locks still take precedence.

Headless mode cannot open an approval prompt. If a tool still requires a human decision, the request fails closed with exit code 20.

Exit codes

Code	Meaning
0	Completed successfully. For action requests, at least one executable tool call completed.
20	Refused, cancelled, or blocked by permission policy.
21	No actionable tool call completed, or a human answer was required.
22	A tool failed, stayed incomplete, or the turn limit stopped verification.
23	The model backend or ACP connection was unavailable before completion.
1	Startup, configuration, authentication, output, or another unclassified failure.

Script against evidence

Treat the process exit code and structured terminal output as the automation result. For action prompts, JSON and streaming terminal records expose observed effects. The local unified JSONL log under ~/.rightnow/logs/unified.jsonl is the diagnostic record when a run needs investigation. Do not treat a confident sentence from the model as proof that local work completed.
