Quickstart

1 · Sign in with X and add GitHub if useful

• X publishing: Sign in with X: one consent covers reading, publishing and your private bookmarks, so there is no second authorization step. PostMine detects X Premium for the 25,000-character limit and publishes only after your explicit action or schedule.
• GitHub material: GitHub is optional. Install the GitHub App, then choose the repository PostMine may use to derive grounded product Facts. Raw private code is not stored.

2 · Create in Main Chat

Attach a reviewed Post, a Find opportunity, or a Fact, then ask Main Chat for the result you need. Keep refining the conversation until the result is ready.

• A reviewed Post can supply its topic, central conflict and delivery, but never the author's biography. PostMine, product Facts, a pitch or a call to action appear only when you ask for them. Factual claims stay grounded in current Facts, verified own X posts and product details you state in the conversation. Your explicit request for language, tone, format, length or product content takes priority over defaults.
• When you explicitly request factual personal context and it is missing, Main Chat asks one clarification question as an ordinary chat message. Your answer can become a Fact for the next turn.
• Contextual suggestion chips send ordinary chat instructions immediately. If a required connection is unavailable, the chip becomes an honest connection action instead of pretending the command ran.
• Pasted text remains editable conversation content, and attached long X Posts use their full source text.
• AI credits are what Main Chat spends on drafts, edits and replies. A Find search does not spend AI credits; Find is limited by its own search cadence.
• X is the only connected publishing platform. Keep a result as a Draft or choose Publish after review; a schedule also requires your explicit setup.

3 · Tone of voice

Main Chat uses the writing voice from your X identity when it is ready. While voice preparation is pending or has failed, you can retry. If material is insufficient, rework from another angle.

Your current request for language, tone, format, length or product content takes priority over the detected voice and other defaults.

Limits cheat-sheet

• X: 280 characters, or 25,000 with Premium; URLs count as 23 characters
• Threads: 500 characters in the pre-filled composer you publish from yourself
• Tone of voice: prepared from your X identity; retry if preparation fails, or rework from another angle when material is insufficient

X publishing limits and frequency

PostMine has no daily publishing cap of its own. It respects X's official API limits and reports a failed target without changing a target that already succeeded.

• Nothing publishes without your explicit Post now action or a schedule.
• PostMine never automates direct messages, comments, follows or engagement.

Account safety

• Nothing publishes without your explicit Post now action or a schedule.
• No direct-message, comment, follow or engagement automation.
• Connected publishing uses X's official API, never browser automation.
• Threads results open a pre-filled composer in your own Threads session.
• Scheduled X posts fire with a small random offset, up to 2 minutes, so they do not look machine-fired.

Plans and billing

Free and Pro each include one active project. Free includes 200 AI credits once. Free includes one initial Find clients search; Pro can refresh Find clients every 24 hours after use. Unlimited bookmark and inspiration refreshes are included on both plans. A short cooldown prevents repeated requests. X availability and rate limits still apply. Pro costs $29 per month. AI credits: 3,000 per subscription month. Drafts, regenerations and AI edits use the same balance. Manual edits and publishing do not use credits, and publishing works even at a zero balance. Find clients remains available.

• Pay yearly and save 20%: $278 upfront, an effective $23/mo.
• A card is required when you upgrade to Pro. Cancel in one click anytime in Billing.
