ManyChat vs Planoly: Which Should You Use for Instagram Comment-to-DM?

Pick ManyChat if you need more than Instagram: WhatsApp, TikTok, SMS or email, AI replies, or big branching flows. Pick Planoly Automations if you already plan and auto-post your Instagram content in Planoly and want the comment-to-DM attached to the post while you schedule it.

That is the short answer. The longer one depends on how you sell, how big your audience is, and how much you want to manage. You have probably seen the "comment GUIDE and I'll send it to you" posts and thought, "I should be doing that." Then you priced it out and got confused. This guide compares the two side by side, using only what each company publishes about itself, so you can decide in one read.

‍

What Does Each Tool Actually Do?

ManyChat is a dedicated chat automation platform. It works across Instagram, Messenger, TikTok, Telegram, WhatsApp, SMS and email, according to its pricing page. You build flows that respond to comments, DMs and other triggers, and its Pro plan adds AI automation. It describes itself as an official Meta Business Partner. It is a full messaging tool that does Instagram very well.

Planoly Automations lives inside the Planoly planner. Per the Automations help article, it sends a DM to anyone whose comment, story reply or DM to your Instagram account matches your keywords, and it can leave a public reply under the comment. You can set it up right in the post builder while you schedule a post, or from the Automations page. It is Instagram only, uses Meta's official Instagram API, is included in every paid plan, and the post has to publish through Planoly with Auto-post.

Why it matters: These tools start from different places. ManyChat starts from the conversation. Planoly starts from the post. Which starting point matches your day is most of the decision.

How We're Comparing Them

We looked at five things a business owner or social media manager actually weighs:

1. Channels covered. Where can the automation reply?

2. Triggers. What makes it fire: comments, story replies, DMs?

3. What the DM can contain. Links, files, media, buttons.

4. Pricing model. Flat plan, or billed by the people you reach?

5. Workflow fit. Does it sit where you already work?

How Is Each One Priced?

Pricing is the question people ask most in Reddit threads about comment-to-DM tools, and it is worth getting right before you commit. The two tools use different models.

ManyChat bills by monthly Active Contacts, the number of people who interact with your automations in a billing month. Its published plans:

• Free: 25 Active Contacts, up to 4 active automations and 2 channels.

• Essential: $17/month billed monthly, or $14/month billed annually, with 250 Active Contacts and up to 2 channels (ManyChat Essential).

• Pro: $39/month billed monthly, or $29/month billed annually, with 2,500 Active Contacts, up to 3 channels including WhatsApp, SMS and email, plus AI automation (ManyChat Pro).

• Business and Advanced: $69/month and $139/month billed annually, with 7,500 and 25,000 Active Contacts.

• Overage: $0.10 per extra contact on Essential, $0.05 on Pro and $0.025 on Business (monthly billing). One person counts once per billing month, and you can set an overage threshold so the bill can't run past a limit you choose.

Planoly's pricing page lists "Automate Instagram DMs" on all three paid plans: Starter at $14/month, Growth at $24 and Pro at $47 when billed annually ($16, $28 and $55 billed monthly), with a 14-day free trial for new subscribers. Those plans also include the planner, calendar and scheduling, so you are not paying for automations alone. Automations are included in every paid Planoly plan, and Planoly's pricing lists no per-contact or per-DM charges. Annual billing saves up to 15%.

Why it matters: A contact-based bill scales with the people you actually talk to, which suits a steady audience, and ManyChat's overage threshold lets you cap it. A flat plan is easier to predict when one post takes off. Know which model fits you before your best post goes viral.

‍

What Are the Limits?

Every tool works inside Instagram's rules. Meta's Private Replies documentation allows one private reply per comment, sent within 7 days, with follow-ups only after the person responds. That is why both tools use a first message with a button.

Planoly's own limits, from its help article:

• Up to 10 keywords per automation, matched without case and anywhere in the comment, so "link" also answers "LINK" and "link please."

• An opening message of up to 640 characters with one button (label up to 20 characters). When someone taps it, the rest of the messages send.

• Up to 10 messages per automation, and up to 5 photos, videos and PDFs across them.

• One reply per post per person, even if they comment three times.

• DM automations are created on the Automations page only, and need at least one keyword.

• Instagram only, with the post published through Auto-post.

ManyChat's limits are mostly set by plan: Active Contacts, number of channels, and which features (like AI) are included.

‍

Where Each Tool Wins

Pick ManyChat if:

• You sell on WhatsApp, TikTok, SMS or email as well as Instagram.

• You want AI-written replies or long, branching flows with lots of conditions.

• Your audience is small and steady enough that the free or Essential contact limits cover you.

• Messaging is a core part of your business and deserves its own dedicated tool.

Pick Planoly Automations if:

• You already plan and auto-post Instagram in Planoly and want one less tool to log into.

• You like setting up the DM at the same moment you write the caption that asks for the comment.

• Your automations are mostly "comment a word, get a link, guide or freebie," with media, a PDF or a card.

• You want story replies and keyword DMs handled from the same place.

Why it works: The caption and the automation are one idea. When you write "comment GUIDE" and build the DM that delivers the guide in the same screen, there is no gap where the keyword in your caption and the keyword in your automation drift apart.

‍

Which Should You Pick?

Use this as your decision rule:

1. Pick ManyChat if Instagram is one of several messaging channels, or you want AI and complex flows.

2. Pick Planoly if Instagram is your main channel and you already schedule there.

3. Consider both if you run a big multi-channel funnel in ManyChat but want Planoly for planning. Just note that Instagram lets only one app send DMs in each conversation, so decide which tool owns your Instagram DMs. Planoly's help article explains how to set this under Instagram Conversation Routing.

Frequently Asked Questions

Is Planoly a ManyChat alternative?

For Instagram comment-to-DM, story replies and keyword DMs, yes. For WhatsApp, TikTok, SMS, email or AI replies, no. Planoly Automations is Instagram only.

Is ManyChat worth it?

It can be, especially if you message people on several channels. Check how many Active Contacts you expect each month, because that drives the price.

Can I use ManyChat and Planoly at the same time?

Instagram lets one app send DMs in each conversation. If another app holds a conversation, Planoly's DMs in it fail. Choose a default app under Instagram Conversation Routing on the linked Facebook Page.

Do I need a paid Planoly plan for Automations?

Yes. Automations come with a paid plan, and the post must publish through Planoly with Auto-post.

‍

TL;DR

• ManyChat: multi-channel, AI and complex flows, billed by Active Contacts.

• Planoly Automations: Instagram only, built into the post you are scheduling, included on paid plans from $14/month billed annually.

• Pick the one that matches where you already work.
