Instagram Comment Agent
Show up in the conversations your buyers are already having on Instagram — like posts, leave AI-drafted replies, discovered by hashtag or URL, paced safely.
Key takeaways
- Two targeting modes: hashtag search using your configured tag list, or a direct post/reel URL.
- Likes each match and drafts an AI reply aligned to your brand voice, product context, and Instagram-specific guidance.
- Editable daily ranges — 8–14 comments and 16–28 likes by default, with a wider like-to-comment gap than LinkedIn.
- Runs completely independently from the LinkedIn agents: own Chrome profile, own daily limits, own counters.
- Same human pacing engine: 12–25 min gaps at the safest setting, 5–18 min steady, or clustered bursts.
- Single-run mode lets you post a comment you typed yourself before handing tone over to the AI.
Instagram is where a lot of B2C, creator, and community conversations actually happen — and the principle from LinkedIn carries over: consistent, relevant engagement beats sporadic bursts. The Instagram Comment Agent brings the same AI-assisted, human-paced workflow to Instagram as a fully separate agent with its own limits and its own browser profile.
Hashtags do the discovery, which changes the game a little compared with LinkedIn keyword search: you're looking at whoever posted under a tag recently, so tag choice is the single biggest lever on quality.
How it works
- 1
Choose Once or All day
Once performs a single like + comment and stops. All day keeps engaging with randomized spacing until it reaches the daily target rolled from your configured ranges.
- 2
Point it at posts
By hashtag pulls a recent post from your tag list in Setup (one per line, with or without the #). Specific URL takes any instagram.com/p/… link. All-day mode works from your hashtags.
- 3
Like, then draft the reply
The agent likes the post first, then the AI writes a comment using your product details, shared writing style, and Instagram-only guidance. On a single run you can turn AI off and post an exact comment you typed.
- 4
Space it out like a person
Gaps between actions are randomized per action, with forced longer breaks layered on top. Expect several minutes between each like and comment — the run log shows the wait timers.
- 5
Track it
The friendly log narrates each step, session counters show comments and likes for the current run, and the History tab keeps a record across restarts.
Choosing hashtags that actually work
Mega-tags are a trap. A tag with millions of posts gives you a firehose of unrelated content, and the posts you land on will have hundreds of comments where yours is invisible. Narrower, niche tags put you in front of fewer people who are far more likely to care.
- Start with 5–10 specific tags that describe your niche the way your audience describes it, not the way a marketer would.
- Mix a couple of broader tags in for volume, but keep the core of the list narrow.
- Enter one per line — the # is optional, so both #saas and saas work.
- Revisit the list after a week. Whatever produced real replies stays; the rest gets cut.
How the AI writes Instagram comments
Instagram tone is different from LinkedIn tone, so the agent keeps a separate guidance field for it while still inheriting your shared writing style. That means one voice across your accounts, tuned per platform — emoji usage, length, how casual to go, what to avoid.
Your product details from Settings feed every reply, so the comment can reference what you're building where it fits naturally. AI replies run on the monthly AI credits included in your plan — no separate API key to configure.
Daily limits, tuned for Instagram
Same range-based system as LinkedIn — a random target is drawn inside each range every day — but with a wider like-to-comment gap, because Instagram engagement skews far more toward likes in normal use.
| Setting | Default range | What it does |
|---|---|---|
| Comments per day | 8–14 | AI comments posted before the agent stops for the day |
| Likes per day | 16–28 | Deliberately higher than comments — the low-risk signal |
| Likes over comments gap | 8–12 | Minimum extra likes above the comment count, randomized daily |
Your plan sets the ceiling those ranges live under: 15 Instagram comments and 30 likes a day on Starter, 30 and 60 on Pro, 60 and 120 on Agency — counted separately from your LinkedIn allowance.
Pacing
| Speed | Gap between actions |
|---|---|
| Recommended (natural pace) | Varies per action — mostly steady, with occasional very-slow and bursty stretches |
| Slowest — safest | 12–25 minutes |
| Steady — even spacing | 5–18 minutes |
| Fastest — bursts | 2–5 minutes, then 15–25 minutes |
Expect a full All-day run to take most of the day. That's the point — an account that fires fourteen comments in twenty minutes looks like exactly what it is.
Why it runs separately from LinkedIn
Each platform has its own detection patterns and its own audience behaviour, so SocialKaptan keeps LinkedIn and Instagram as fully independent agents: separate Chrome profiles, separate daily limits, separate counters and history. You can run both channels in parallel, or focus on one, without either affecting the other's pacing or caps.
The Instagram Comment Agent does share its Instagram session with Instagram Campaigns, since both act as the same account — one warms the public feed, the other works an imported contact list. Only one of the two runs at a time.
Setup checklist
- 1Connect Instagram once in the desktop app — you log in yourself and the session stays in a local Chrome profile.
- 2Fill in product name, tagline, and description in Settings, and set your shared writing style.
- 3Add 5–10 hashtags in Setup → Targeting, one per line.
- 4Add Instagram-specific guidance in Setup → Style — especially emoji and length preferences.
- 5Run once with AI on and read the comment before it posts anywhere sensitive; adjust guidance as needed.
- 6Check Setup → Limits, then start All day.
Frequently asked questions
Two ways: hashtag search using the tag list in Setup → Targeting (one per line, # optional), or a direct instagram.com/p/… URL you paste on a single run. All-day mode works from your hashtags.
No. Instagram and LinkedIn are fully independent agents with separate Chrome profiles, separate daily comment and like ranges, and separate plan caps — 15 comments + 30 likes per platform on Starter, 30 + 60 on Pro, 60 + 120 on Agency.
It draws a random target inside the ranges you configure — 8–14 comments and 16–28 likes by default — so the count varies day to day rather than hitting the same number every time.
Likes are cheap and low-risk; comments are the expensive action. The agent enforces a randomized gap of 8–12 extra likes above its comment count, which is closer to how a real Instagram account behaves.
On a single run you can turn AI off and post an exact comment you typed yourself, which is the cleanest way to verify targeting and pacing separately from tone. To review AI output, run once and read what it posted in the log before starting All-day mode. (The dedicated type-but-don't-submit preview option lives on the LinkedIn Comment Agent.)
Yes. Each has its own agent and browser profile with separate limits, so you can grow on both in parallel. Run All starts every connected agent's daily mode together in one click.
This agent is for public visibility — it likes and comments on hashtag posts so people discover you. Campaigns run a per-person sequence over a contact list you import: like, comment, wait, DM, and hand off to a book-meeting agent. They use the same Instagram session, so only one runs at a time.
It can, and usually should. Your shared writing style applies everywhere, but Setup → Style holds Instagram-only guidance for tone, length, and emoji use, so you're not posting LinkedIn-flavoured comments under a hashtag.
It uses the same local-execution model as the LinkedIn agents: your own Chrome profile and login on your own machine, randomized pacing with forced breaks, and daily caps well under aggressive volume. No tool can promise zero risk, and Instagram is stricter about new accounts, so start with the default limits.
Yes — "Run without showing the browser" moves Chrome off-screen rather than using a detectable headless mode. Leave it visible while you're setting things up, since it makes problems much easier to spot.
