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.

Interactive TUI

RightNow Agent opens its interactive terminal UI when you launch it without a headless prompt or subcommand. Model inference goes to your configured OpenAI-compatible provider, while approved tools run on your machine.

Launch on Windows

Set RIGHTNOW_API_KEY, then run the PowerShell launcher. It starts rightnow-pager.exe and reads ~/.rightnow/config.toml.

powershell

$env:RIGHTNOW_API_KEY = "<your key>"
.\rightnow.ps1

Running the binary without -p, --prompt-json, --prompt-file, or a subcommand opens the TUI. Windows is the measured product path; macOS and Linux support is not verified for this release.

Composer and context

Write a prompt

Type a request in the composer and press Enter. The scrollback streams responses, tool calls, command output, and file edits. Press Tab to move between the composer and scrollback.

text

Explain the authentication flow and identify its tests.

Attach files with @

Typing @ opens a fuzzy file picker. It respects .gitignore and hides dotfiles by default. Add a line range for precise context, or use @! to include hidden files.

text

@src/main.rs
@src/main.rs:10-50
@src/
@!.env

Run a command yourself

Type ! on an empty composer to enter shell mode. The command output is added to the scrollback, where RightNow can use it as context.

Commands and render modes

Press Ctrl+P or ? to open the searchable command palette. It contains actions, slash commands, keyboard shortcuts, and available skills. Typing / in the composer opens the slash-command menu directly.

Mode	How to enter	Behavior
Fullscreen	`/fullscreen` or `--fullscreen`	Standard full-screen TUI with the dashboard, theme picker, timeline, and scrollback search.
Minimal	`/minimal` or `--minimal`	Experimental scrollback-native mode using the terminal palette. It exposes minimal-only actions such as `/expand`.

A slash-command switch reopens the same conversation in the other mode for the current session. Set the default screen mode in /settings or under [ui] in the config file.

Prompt queue and steering

You can keep typing while a turn runs. With the default queue behavior, pressing Enter adds the message for the next turn. Press Enter again on an empty composer to send the first queued item now. Open the queue pane with Ctrl+;, with Ctrl+' available as a Windows alternative.

If [ui].follow_up_behavior is set to steer, queued text is injected at the next safe model or tool boundary. The send-now chord cancels the foreground turn and starts your message next. Outside VS Code-family terminals, Ctrl+I is the stable Windows alternative when Ctrl+Enter is not delivered correctly; VS Code-family terminals use Ctrl+L.

Blocking cards

Questions, permission requests, and the cancel-turn panel temporarily own the keyboard. Tab and Shift+Tab move through the current card, while Enter confirms the focused choice.

Card	Escape behavior
Question	Clears a selection first, then parks focus in scrollback. Press Tab to return.
Permission	Parks focus in scrollback without approving or denying the request.
Cancel turn	Chooses keep running and closes the panel.

Themes

rightnow-night is the shipped default. In fullscreen mode, use /theme or its /t alias to preview and select the other bundled themes. Minimal mode ignores theme settings and uses the terminal's own palette.

Local execution

Provider inference is remote, but file, shell, search, and editing tools execute locally under the active permission policy.
