Rook Signal is a focused tool for sustaining a LinkedIn presence without performing for it. You pick up to twenty target accounts per workspace, write a persona from three short samples, and clear a pre drafted morning queue. Every reply is written in your voice. Every archive is yours to export. ### Rook Intelligence Rook Intelligence is the writing layer inside Rook Signal. It runs on the model provider you choose. Rook Intelligence is the persona, rule, and prompt layer that sits above your selected model. It is tuned for short form reply, not long essays. Drafts land between fifteen and sixty words. It reads the post first, your tone second, your rules third. ### Rook Persona Rook Persona is a small library of your voice stored per workspace, built from samples, a tone, and rules. Rook Persona learns your cadence from three to ten short samples. It takes one of five tones. It respects a rule set that lists words you never use, closings you always want, and length preferences. The persona is private to the workspace. ### Workspace A workspace is a sealed environment with its own persona, target list, queue, history, and provider key. Rook Signal workspaces come in two flavors. Creator holds a single personal voice. Business supports multi seat collaboration with a shared brand persona. Switching between workspaces takes one click and nothing leaks across. ### Creator workspace A Creator workspace is the Rook Signal flavor for a single personal voice. A Creator workspace is designed for one writer. It holds one persona, one target list of up to twenty accounts, one queue, one history, and one provider key. It is the fastest way to start. ### Business workspace A Business workspace is the Rook Signal flavor for teams sharing a brand voice. A Business workspace supports multiple collaborators. The persona is shared. The archive is shared. Role based access controls who can edit targets and who can post. Rook ID handles authentication across seats. ### Target account A target account is a LinkedIn profile Rook Signal watches for new posts. Up to twenty per workspace. You add a target account by pasting its LinkedIn profile URL, adding a human label, and choosing a category. The tracker reads the profile once a night at 8 PM IST and drafts a reply for each new post. ### Tracker The tracker is the daily sweep that reads every target and drafts a reply for each new post. The tracker runs once a day at 8 PM IST. It reads each target account for new posts, pre generates a draft per post using your persona, and records a run log. A live countdown in the dashboard shows the time of the next run. ### Comment queue The comment queue is the morning column of pre drafted replies ready for your review. Each card in the queue shows the original post, a draft in your voice, and three actions. You post, edit, or skip. Filter chips split the queue into Ready, Pending, and Generating. Cleaning the queue typically takes under ten minutes. ### Comment history Comment history is the searchable archive of every comment you have posted through Rook Signal. History is per workspace. Search by account or keyword. Export the full archive as a CSV that opens in any reporting tool. The archive is yours and is never shared between workspaces. ### Tone A tone is one of five registers inside Rook Persona. Your voice stays, the register changes. The five tones are Professional, Friendly, Direct, Thought Leader, and Conversational. Tone is a dial, not a disguise. You can change it at any time and the persona keeps your voice. ### Sample A sample is a short piece of your writing pasted into Rook Persona so it learns your cadence. Three samples are enough to start. You can paste up to ten. Short is fine. Rook Persona studies rhythm, phrasing, and favorite words, not volume. ### Rule A rule is a persona constraint that Rook Intelligence respects on every draft. Rules list words you never use, openings you never want, closings you always include, and length preferences. They apply to every draft forever, until you change them. ### Ready badge The Ready badge is the green pill on a queue card. It means the draft was pre generated overnight. When the tracker runs at 8 PM IST, it pre generates a draft for each new post. Those cards open the morning queue with a green Ready badge. You are not waiting for a model, you are waiting for your judgment. ### Pre generated Pre generated means the draft was written overnight during the tracker run, not just now. Rook Signal pre generates drafts so the queue is full when you open it. Regenerating a pre generated draft produces a fresh take using the same persona and rules. ### BYOK BYOK means bring your own key. You plug a provider key into your workspace and Rook Signal uses it. Rook Signal is BYOK by default. You bring a key from Anthropic, OpenAI, Google, xAI, or Groq. Rook Signal never resells tokens. Billing stays between you and the lab. ### Provider A provider is a lab whose model runs Rook Intelligence. Five are supported. The five supported providers are Anthropic, OpenAI, Google, xAI, and Groq. Each workspace stores one provider key. Swap providers whenever you want. Your persona is portable across models. ### Anthropic Anthropic is the Rook Signal default provider. Models include Claude Opus, Sonnet, and Haiku. Anthropic keys start with sk ant. Claude tends to match your cadence better than most and reads the full post, not just the first line. Opus is for depth, Sonnet for the daily queue, Haiku for volume. ### OpenAI OpenAI is a provider inside Rook Signal. Models include GPT 4.1 and GPT 4o. OpenAI keys start with sk proj. Rook Signal adapts the prompt shape to whichever model you pick. Any OpenAI compatible endpoint works, including self hosted clusters. ### Google Google is a provider inside Rook Signal. Models include Gemini 2.5 Pro and Flash. Google keys start with AIza. Gemini brings the largest context window of any supported provider, useful when the accounts you follow write long essays inside LinkedIn. ### xAI xAI is a provider inside Rook Signal. The model is Grok 4. xAI keys start with xai. Grok pairs naturally with the Thought Leader tone because it opens on the angle rather than the compliment. ### Groq Groq is a provider inside Rook Signal serving Llama and Mixtral at LPU speed. Groq keys start with gsk. Regeneration is often sub second. It is the best fit when trackers run across many accounts and you want drafts to land before you open your phone. ### AES 256 GCM AES 256 GCM is the authenticated encryption standard Rook Signal uses to store every API key at rest. Keys are encrypted before they touch the database and masked in the UI. The full value is never returned to the browser. Removing a key revokes Rook Signal access immediately. ### Mismatch detection Mismatch detection warns you when a stored key prefix does not match the selected provider. Rook Signal inspects the prefix of the stored key. sk ant belongs to Anthropic, sk proj to OpenAI, AIza to Google, xai to xAI, and gsk to Groq. A mismatch triggers a visible warning before the next draft. ### Account health Account health is the per target status reported by the last tracker run. The four states are Active, No recent posts, Blocked, and Pending. Each appears on the tracker page for every target. Blocked accounts are surfaced openly so there are no silent failures. ### Run log The run log is the seven day history of tracker runs. It records duration, posts found, comments generated, and errors. The run log lives on the tracker page. It is the source of truth for what happened across the last week. It is useful for spotting long runs and flagged accounts. ### Regenerate Regenerate asks Rook Intelligence for a fresh draft using the same persona and rules. Regenerate is one button on a queue card. It returns a new take on the same post. Groq keys produce sub second regenerations. Anthropic and Google keys usually land within a few seconds. ### Skip Skip is the third verb on a queue card. Not every post deserves a reply. Skip removes a card from the queue without posting anything. Skipping is a feature, not a gap. It keeps your voice selective and your archive honest. ### CSV export CSV export downloads your complete comment history as a spreadsheet. Columns include account, post snippet, your comment, link, and date. Every reporting tool opens the file. The archive is yours whenever you want it, with no lock in. ### Category A category is a tag on a target account. Rook Signal ships with more than two hundred options. Categories help you remember why a target matters. Founder, investor, designer, marketer, filmmaker, and so on. The category travels with the archive and supports later reporting. ## Full FAQ ### What is Rook Signal? Rook Signal is a quiet LinkedIn presence workspace.

Time: 4 weeks. Goal: Be familiar in the feeds of target investors weeks before the pitch. Founders who run this play open the round warm. Target investors see them under three to five thoughtful comments before any pitch email lands. 1. Pick twenty investors. Drop the LinkedIn URLs of the investors you plan to pitch into a Creator workspace. 2. Set a Thought Leader tone. Your replies carry a view, not a compliment. Investors read replies before profiles. 3. Clear the queue every morning. Ten minutes before your first call. Post, edit, or skip each card. 4. Open the round warm. After four weeks, send the first email. The name is already familiar. ### Launch week reply campaign Audience: Marketing teams. Time: 1 week. Goal: Every press and partner post during launch week gets a thoughtful brand reply. Launch day goes viral in the feed, but the real reach sits under the posts that reference it. This play turns Rook Signal into a launch week reply channel. 1. Open a Business workspace. Invite your brand lead, two writers, and the founder. 2. Drop twenty accounts. Press, investors, shortlisted partners, and four creators. 3. Use the brand persona. Three brand samples, a Friendly tone, and a shared set of rules. 4. Clear the queue twice a day for seven days. Morning and early afternoon. Export the CSV at the end of the week. ### Three ABM touches before the first DM Audience: Sales. Time: 3 weeks. Goal: Raise DM response rates by building familiarity under your buyer posts. Buyers do not reply to cold DMs. Buyers reply to the rep whose name has appeared under the last three thoughtful comments. 1. Align Rook Signal with your ABM list. Paste the top twenty buyers into a Creator workspace. 2. Pick the Direct tone. Short, blunt, opinion first. Respect your buyer’s time. 3. Three comments rule. Never DM until Rook Signal has logged three posted comments on that account. 4. DM the same week. Reference the specific post in your message. Continue the conversation. ### Three touches before the InMail Audience: Recruiters. Time: 2 to 3 weeks. Goal: Warm candidates so InMails feel like a continuation, not a cold open. Engineers and designers read comments under their posts. Three thoughtful replies from a recruiter move the candidate from stranger to familiar. 1. One workspace per role. Drop twenty candidate profiles for the role into a workspace. 2. Use Conversational or Friendly. Human, warm, never salesy. 3. Post three comments per candidate. Over two to three weeks. Rook Signal handles the drafting. 4. Then InMail. Reference the posts. Invite to a quick call. ### Awards season reply plan Audience: Marketing teams. Time: 3 to 4 weeks. Goal: Be present in the jurors, shortlisted peers, and reporter feeds during the judging window. Awards decisions get made in rooms, but reputation gets made under posts. This play turns Rook Signal into a focused awards season reply plan. 1. Target the jury and shortlist. Drop the jury, your shortlisted peers, and covering reporters into a Business workspace. 2. Tone Professional. No celebration. No throat clearing. A calm, informed voice. 3. Clear the queue daily through judging. Three to four weeks. No gaps. 4. Export the archive. After awards close, export the CSV for your year end review. ### Personal thought leadership sprint Audience: Creators and operators. Time: 90 days. Goal: Grow a reputation for a specific opinion by replying under the fifty creators who own that conversation. Most growth on LinkedIn comes from consistent replies, not viral posts. This play sets a 90 day sprint on a single idea. 1. Pick your angle. One opinion. Write it as a one line thesis in your workspace rules. 2. Thought Leader tone. Your drafts open on the angle, not the compliment. 3. Swap accounts every two weeks. Watch which creators are closest to your angle this fortnight. 4. Review the archive monthly. Export the CSV. Read yourself back. Tighten your rules. ### Employee advocacy without forced posts Audience: Marketing teams. Time: Quarterly. Goal: Get a team visibly present under industry posts without forcing anyone to publish. Forced employee advocacy backfires. A reply plan is softer, more useful, and more durable. 1. Open a Business workspace. Invite six to ten contributors across teams. 2. Shared persona. One brand persona. Every contributor writes through it. 3. Twenty industry accounts. Thought leaders, customers, partners. 4. Weekly review ritual. Twenty minutes each Friday. Scan the archive. Share highlights. ### Post funding visibility window Audience: Founders and marketing teams. Time: 30 days. Goal: Use the two weeks of attention after an announcement to build lasting presence. Announcement day is loud. Presence is quiet. The founders who turn an announcement into relationships do it in the thirty days after. 1. Drop investors, press, partners. All on day zero. Twenty names. 2. Tone Friendly. Warm, open, curious. No celebration in every reply. 3. Twenty days of daily queue reviews. Morning only. Ten minutes. 4. Export and share internally. The CSV is a record of post announcement presence. ### Community building under fifty creators Audience: Creators. Time: Ongoing. Goal: Build genuine relationships with peers by showing up under their posts for a full year. Community is a one on one practice done at scale. Rook Signal keeps the one on one honest and the scale sustainable. 1. Pick twenty peers in the first workspace. Rotate in ten more every quarter for a second workspace. 2. Conversational tone. Reads like coffee, not copy. 3. Comment daily, never skip. If a peer posts three times a week, you show up three times a week. 4. Review quarterly. Your archive tells you who your community actually is. ### Warm job search campaign Audience: Senior operators. Time: 3 weeks. Goal: Make the hiring manager feel they already know you before the application. A warm applicant is a different applicant. Show up under target hiring managers for three weeks before you apply. 1. Twenty hiring managers and senior ICs. At the companies you would like to join. 2. Direct tone. Short, honest, useful. 3. Three weeks of daily comments. Ten minutes a morning. 4. Apply with a reference to your replies. A short, confident cover message lands differently. ### Partnership outreach sequence Audience: Business development. Time: 4 weeks. Goal: Open a partnership conversation from familiarity rather than a cold ask. BD emails sent cold are the hardest. BD emails sent to someone who has seen your brand under their last four posts are easy. 1. Pick twenty target partners. Founders, heads of partnerships, integration leads. 2. Professional tone. Calm, informed, business ready. 3. Four comment rule. Never email until Rook Signal logs four posted comments. 4. Short, specific email. Reference the most recent post. Keep it under a hundred words. ### Investor update reply loop Audience: Founders. Time: Monthly. Goal: Turn your investor update posts into a public dialogue with peers and operators. If you publish a public update, the replies you leave under peers the same day compound your update’s reach. 1. Publish your update. Keep it tight and honest. 2. Open Rook Signal the same morning. Clear the queue. Leave one strong reply under each of the five most relevant peers. 3. Skip the weak ones. Not every post deserves a reply. Skipping keeps your voice sharp. 4. Log in the archive. The CSV is the record of your presence that month. ## Quotable stats - Targets per workspace: 20. The deliberate cap. Twenty keeps your presence focused. - Daily tracker time: 8 PM IST.
