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.

Subagents and Background Tasks

RightNow Agent can delegate independent work to child sessions and keep long-running commands active without blocking the conversation. Each subagent has its own context and reports a result to its parent.

Delegate with the task tool

The task tool starts a child session with a focused prompt, a short description, and an agent type. A task can block until the child finishes or run in the background and return an ID for later inspection.

Agent type	Use
general-purpose	Full-capability work that may read, edit, and execute under its permissions.
explore	Read-only investigation, search, and shell inspection.
plan	Codebase exploration followed by a structured implementation plan, without file edits.

Depth limit

Only the top-level session can create subagents. A child cannot create another child, so the maximum nesting depth is one.

Tasks and todos

Shortcut	Pane	Contents
Ctrl+G	Tasks	Subagents, background commands, monitors, loops, statuses, elapsed time, and task IDs.
Ctrl+T	Todos	The current task's separate todo list.

Background commands

A command launched through run_terminal_command with background: true returns a task ID immediately. Press Ctrl+B to move an already-running foreground command into the background.

Tool	Purpose
get_command_or_subagent_output	Read current output and status, optionally waiting up to a timeout.
wait_commands_or_subagents	Wait for any or all of up to 20 task IDs.
kill_command_or_subagent	Stop a command or subagent, or report that it already exited.

Monitor and scheduled loops

Real-time events with monitor

The monitor tool runs a long-lived script and turns each new stdout or stderr line into a conversation notification. Filter noisy streams and use line-buffered pipes so events arrive promptly. A persistent monitor runs for the lifetime of the session until it is killed.

Periodic checks with /loop

text

/loop 5m Check whether the test suite passes
/loop 2h Summarize new commits

Intervals use seconds, minutes, hours, or days. The minimum is 60 seconds. A loop fires immediately, creates a new turn on each interval, expires after 7 days, and is managed through the scheduler tools.

Personas

A persona is a behavioral layer for a subagent. It can shape tone, output format, task focus, model, reasoning effort, isolation, and declared input or output contracts without replacing the underlying agent type.

Open /personas to manage personas, or /config-agents to open the full Agents and Personas modal. Project personas live under .rightnow/personas/*.toml; user personas live under ~/.rightnow/personas/*.toml.
