Smart pacing & rate limits

How smart pacing works

ThreadPilot watches every reply you generate and applies three layers of throttling: a daily cap, an hourly grace window and a per-author limit. Together these keep your replying rhythm well inside the range a human poster would sit in, even on your most active days.

Limits are evaluated in real time. If a generation would push you past a threshold, the extension surfaces a soft warning instead of blocking you outright — you stay in control while staying safe.

The three pacing rules

• Daily cap — a rolling 24-hour ceiling on how many replies you can send through ThreadPilot. Free plan: 10/day. Pro: unlimited, but still soft-paced.
• Hourly grace — replies are spaced so you never burst more than a handful in a single 60-minute window. Spikes are the #1 signal X uses to flag automated activity.
• Per-author throttle — at most 3 replies per day to the same X account, so your engagement never looks like targeted spam.

Manual insert is required

No reply is ever posted automatically. ThreadPilot only fills the X reply box; you always click Reply yourself. That single human click is the most important safety layer — it means every post is genuinely yours.

When you hit a limit

If you reach the daily cap, the extension shows a friendly notice with the time your next slot opens. The hourly window resets gradually rather than all at once, so you can keep replying naturally as the hour rolls forward.

Why pacing matters

X aggressively detects automation patterns: high reply velocity, repeated targeting of the same account, and identical-looking text are the three biggest red flags. Smart pacing addresses all three — velocity through caps, targeting through the per-author rule, and similarity through ThreadPilot’s tone variation.
