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.

Configuration

RightNow Agent resolves its user home from a non-empty RIGHTNOW_HOME, then GROK_HOME for older setups, then ~/.rightnow. The repository launchers export both names and use config/rightnow.toml as the shipped template.

Synchronization rules

The template requires [rightnow].config_version = 6.

A missing user config is copied from the template.
A config without config_version is treated as version 0 and upgraded. A non-integer or negative version is rejected.
An older valid config is backed up, keeps owner values and unknown keys, receives missing template keys, and advances to version 6.
A version equal to 6 with missing required keys is reported and left untouched.
A version newer than 6 is reported and left untouched.
The active file is re-read before replacement. A concurrent change aborts the upgrade and leaves the backup available.

text

rightnow-pager config sync --config <path> --template <path>

This sync command is dispatched before the TUI-owned parser, so it may not appear in ordinary help output. Without a launcher, a legacy ~/.grok home is used only when it contains config.toml and ~/.rightnow does not exist.

Shipped values

Key	Shipped value
config_version	6
warm_daemon	true
warm_daemon_persistent	false
one_call_transactions	true
preload_named_files	true
workspace_map	true
act_first	false
retry_recoverable_tool_failures	true
bounded_prompt_slimming	true
dynamic_tools	true
context_packing	not set, parser default false
eager_tools	true
turn_model_call_limit	24
turn_time_budget_secs	600
turn_repeated_failure_limit	3
turn_spend_limit_microcents	5000000
web_fetch	true
web_search_engine	duckduckgo
disallowed_tools	image and video generation tools

When the turn-limit keys are omitted, parser fallbacks are 12 model calls, 30 seconds, and 2 repeated failures. An omitted or zero spend limit disables the spend cap. Boolean [rightnow] extension fields default to false unless the shipped template enables them.

Features and identity

toml

[features]
remote_fetch = false
telemetry = false
turn_summary = false

[agent]
system_prompt_label = "RightNow"

remote_fetch = false disables optional remote model-catalog fetching. It does not disable the model API, web tools, MCP servers, hooks, or custom providers.

telemetry = false disables the configured outbound telemetry path. It does not remove the local ~/.rightnow/logs/unified.jsonl diagnostic log. Neither launcher passes a system prompt override, and --rules appends text inside <human_rules>.

Launcher environment

Both launchers honor an existing GROK_HOME. If absent, they use the user's .rightnow directory.
They set GROK_WEB_FETCH=1 and RIGHTNOW_WEB_SEARCH_ENGINE=duckduckgo only when the caller has not set them.
They append the image and video tools to --disallowed-tools unless the caller already supplied that argument.

Removed local-runtime keys

The parser tolerates these keys as unknown fields and warns about them. They have no current runtime effect. Back up the config and remove them rather than treating the warnings as an active compatibility mode.
