An AI agent priced per conversation is built for a back-and-forth: qualify, answer, handle the objection, book the call. If that is your sales motion, a conversation meter is the right unit and this post will not talk you out of it.
It is the other case that needs writing down — the business whose funnel begins and ends under a Reel.
What their plans cover
Read from their pricing page on 24 September 2026: Starter at $39 a month for 400 conversations with Instagram and website; Growth at $89 a month for 1,600 conversations across all channels including WhatsApp; Pro at $279 a month for 6,000 conversations; Enterprise on request; and Indian pricing shown from ₹7,999 a month. They define a conversation as all messages exchanged between the agent and one customer within a day. The company is TailorTalk Private Limited, Bangalore, and the page carries a Meta Partner badge.
A conversation-day is a sensible unit for an agent. It does not punish a customer for asking three follow-up questions, which a per-message meter would.
When it is the wrong unit for you
Count last month honestly.
If two hundred people commented "link" and twelve had a real conversation, then on a conversation meter you are buying capacity for two hundred and twelve interactions, of which two hundred were a single templated sentence.
What an Instagram-only stack actually needs
- Comment to DM, on the official API. The whole funnel starts with a public comment and a private reply, inside Meta's windows — 7 days for a comment, 24 hours for a DM.
- Templates that cost nothing. The repeated question is the majority of the volume and should be free at any scale.
- A real answer for the unpredictable comment. Somebody's skin type, their city, the pack they already bought. This is where a model earns its keep and nowhere else.
- A record of refusals. Windows close, duplicates arrive, humans take over mid-thread. A named reason is the difference between operating and hoping.
- Rupee billing with a GST invoice. A dollar subscription costs the forex markup and gives your accountant nothing to claim.
Where we fit
PostEngage does Instagram comments and DMs and nothing else. No WhatsApp, no website widget, no Messenger, no booking flows, no canvas. If a real part of your revenue arrives through any of those, TailorTalk covers ground we do not and the comparison ends there.
Templated replies are free and unlimited. One credit is spent when the model writes a new reply, drafted against a voice profile built from replies you actually wrote; when it is unsure, your template goes out instead. The free tier is 100 credits with no card and packs start at ₹499.
An agent is priced to hold a conversation. Most Instagram comments do not want a conversation. They want an answer and a link.
The ten checks, briefly
Before any reply leaves, ten run in order: kill switch, connection, takeover, window, dedupe, cooldown, quiet hours, rate budget, credits, content safety. The first failure stops the send and writes down why. Takeover is the one small teams notice first — the moment a human replies by hand, automation stands down on that thread rather than talking over them.
What the setup looks like on a narrow tool
Five screens, and the first live reply usually happens inside fifteen minutes. Connect Instagram with three permissions, where Meta runs the login so no password reaches us. Write the trigger: a post or your next post, then the words people actually type, with a negative keyword to hold the reply back. Write the two replies, the public one that keeps the post moving and the private one that carries the link. Test on yourself, which runs the whole pipeline and the same ten checks and spends no credits. Then press Go live and read Activity the next morning.
There is nothing else to learn, which is the honest upside of buying a smaller product than an agent platform.
A fortnight of evidence beats a feature table
Checklist
If the second number is large and rising, an agent is the correct purchase and a reply tool will feel thin. If the first number is nearly all of it, start on a free tier, load your four commonest answers as templates, and see what is genuinely left over for a model to do.
The sourced head-to-head is on our TailorTalk comparison, the rupee arithmetic against dollar-billed tools is in the cheapest way to automate Instagram DMs in India, and what every tool here is bounded by is in is Instagram DM automation safe.
