ReachleeInstagram AI auto reply tools
that stay inside Meta's rules
Seven ways to auto reply to Instagram DMs with AI, from Meta's free instant reply to full knowledge-grounded agents. What each free tier really sends, what AI costs once you pay, and which one to pick. Reachlee includes AI at $14/mo (₹799 in India).
Short answer
The best Instagram AI auto reply tools in 2026 are Reachlee for knowledge-grounded replies at a flat $14/mo (₹799 in India), AutoDM if you want to try AI DMs free before paying, and Manychat if you already build multi-channel flows. Meta's own instant reply is free but sends one fixed greeting, not an answer. No compliant tool offers unlimited free AI, because every reply costs the vendor model time.
Free tiers compared: what you actually get for $0
| Tool | Free plan | AI on the free plan? | What free actually sends | Paid AI starts at |
|---|---|---|---|---|
| Reachlee | Yes: 1 account, 1,000 DMs/mo, 10 leads | No. AI starts on Growth | Your keyword automations, comment-to-DM, story replies, no branding | Growth $14/mo (₹799 India), 1,000 AI credits |
| AutoDM | Yes | About 10 AI replies/mo | AI DMs answered from your posts, until the allowance runs out | Pro $13/mo |
| Meta Business Suite instant reply | Free, built in | No. One fixed message | The same generic greeting to every new conversation | No paid tier; it never answers questions |
| ReplyRush | Yes: 1,500 DMs/mo, branded, 30-day data | Keyword-based; generative AI not documented publicly | Keyword and comment-to-DM replies with ReplyRush branding | Lite $10/mo (keyword automation, not AI) |
| Manychat | Yes: roughly 25 active contacts | No. AI is in Pro | Keyword flows for a handful of contacts | Pro from $39/mo for 2,500 contacts |
| Inrō | Yes: 100 active contacts | Partly; verify which AI features the free tier includes | Intent-detected DM replies for a small contact list | From €12.99/mo, scales with contacts |
| Chatfuel | No. 7-day trial | Trial only | Nothing after day seven | Fuely AI tiers from roughly $14.99–$49/mo |
Every figure as of September 2026; verify on each vendor's pricing page before deciding. Free tiers change more often than paid ones.
Review the seven, one honest verdict each
What the AI answers, where it gets its knowledge, and what the free tier is really for.
1. Reachlee — knowledge-grounded AI at a flat $14
Reachlee's Free plan has no AI, and we would rather say that plainly than hide a ten-reply allowance behind a banner. Free covers keyword automations, comment-to-DM, and story replies for one account, 1,000 DMs a month, without branding. AI Replies and AI Comments switch on with Growth at $14/mo (₹799 in India): 1,000 AI credits, one credit per reply actually sent, nothing charged for skips or failed sends. The AI answers only from knowledge you add, scanned website links, pasted text, or an opt-in interview, never from your private conversations. It never invents a price or a link, sends links only from the allowed list, skips greetings and friend chat, and replies in the sender's language. Every reply lands in an Activity feed with the message it answered. Pick it when Instagram is your channel and you want AI that behaves like a careful employee. Skip it if you need WhatsApp.
2. AutoDM — the free AI you can actually test
AutoDM includes its AI DM on every plan, with a small free allowance of about 10 AI replies a month (as of September 2026, some pages say up to 25) and Pro at $13/mo. Your posts and pasted text become the AI's knowledge. Pick it when you want to see AI DMs work on your own account before spending anything. The limitation is that captions rarely contain prices and policies, so answers can be thin exactly where buyers need precision, and the free allowance disappears in a day on an active account.
3. Manychat — AI inside a flow builder
Manychat's AI used to be a $29/mo add-on; its 2026 pricing folds AI into a Pro plan that starts at $39/mo for 2,500 contacts (as of September 2026, verify on manychat.com). The free plan covers roughly 25 active contacts and no AI. Pick it when you run Instagram, Messenger, and WhatsApp from one builder and want the AI as a step inside flows. The trade-off is a contact-metered bill and a flow-first setup: the AI is a node you place, not a switch you flip.
4. Inrō — intent detection with a real free tier
Inrō is AI-first from €12.99/mo, with a free plan covering 100 active contacts (as of September 2026). Its intent detection is among the best in the creator segment. Pick it when your contact list is small and you want conversational replies with EU billing. Model your bill at three times your current audience, because active-contact pricing rises with a good month.
5. Chatfuel — Fuely AI for stores, no free plan
Chatfuel sells its AI as Fuely on paid tiers that third-party write-ups place between roughly $14.99 and $49/mo depending on channel and contact allowance, behind a 7-day trial with no permanent free plan (as of September 2026, verify on chatfuel.com). Its strength is commerce: Shopify data and WhatsApp alongside Instagram. Pick it when a store's WhatsApp support is the real job. For an Instagram-only creator, you pay for machinery you will not use.
6. ReplyRush — a generous free tier, but not AI
ReplyRush's free plan sends 1,500 DMs a month with branding and 30-day data retention, one of the most generous free allowances in the category (as of September 2026). It earns a place here because searches for free auto reply land on it, but its replies are keyword-triggered fixed messages; generative AI replies are not documented publicly. Pick it for free comment-to-DM at low volume. Do not pick it expecting the tool to answer open questions.
7. Meta Business Suite instant reply — free, and not an answer
Meta's built-in instant reply costs nothing and takes two minutes to set up in Business Suite. It sends one generic message to every new conversation: 'Thanks for reaching out, we reply within a day.' That is useful for setting expectations and useless for answering 'how much?'. Turn it on regardless; then decide which tool above handles the actual questions.
Choose an AI auto reply tool in four checks
Check what the free tier really sends
A free plan that sends one greeting, or ten AI replies, is a demo. Decide whether you are testing the product or running your inbox on it. Reachlee Free runs keyword automations at real volume; its AI is paid because every reply costs model time.
Check where the AI gets its knowledge
Tools that answer from your website and a pasted FAQ are accurate. Tools that improvise from captions or have no knowledge step will guess. Ask what happens when the AI does not know: Reachlee stays silent or says the creator will follow up.
Check the guardrails
No invented prices, no links outside an allowed list, honest when asked if it is automated, and a human takeover rule. Reachlee stays out of a thread for 48 hours after you reply yourself, and you can mute any thread or pause everything.
Model the bill at your busiest month
Contact-metered plans grow with your audience. Credit plans charge per reply. Reachlee's 1,000 credits are 1,000 real answers, because skipped and failed messages are never billed.
Turn on Meta's free instant reply today; it sets expectations and costs nothing. If you want to see AI DMs on your own account for free, AutoDM's small allowance is the only honest way to do it. If you already live in Manychat's flow builder, its Pro plan now includes AI. For a creator or small business that wants AI answering real questions from real knowledge, with receipts and a bill that does not grow with the audience, Reachlee Growth at $14/mo (₹799 in India) is the strongest option here. Its trade-off is stated up front: Free and Pro have no AI, and it is Instagram only.
Start free, add AI when you need it
Reachlee Free covers keyword automations for one account. Growth is $14/mo (₹799 in India) with AI Replies, AI Comments, AI Goals, 1,000 AI credits, and 3 Instagram accounts. Business is $29/mo (₹1,499 in India) with 2,500 credits, 10 accounts, and 5 team seats. One credit per AI reply sent; skips and failures are free.
Start freeInstagram AI auto reply tools — FAQ
Is there a free Instagram AI auto reply tool?
Partly. Meta's Business Suite instant reply is free but sends one fixed greeting. AutoDM gives about 10 free AI replies a month (as of September 2026). Reachlee's Free plan has no AI; AI Replies start on Growth at $14/mo (₹799 in India). No compliant tool offers unlimited free AI, because each reply costs the vendor model time.
Are AI auto replies allowed on Instagram?
Yes, when they run on the official Instagram API and follow Meta's messaging rules: reply only to people who messaged you, inside the 24-hour window, never as first contact. Every tool on this page connects through Instagram's own login. Anything that asks for your Instagram password is a browser bot and risks your account.
Will the AI make things up about my business?
It depends on the tool's knowledge model. Reachlee's AI answers only from knowledge you add, scanned website links, pasted text, or an interview you opt into. It never invents prices or links, sends links only from the allowed list, and says the creator will get back to you when unsure. Every reply is logged in the Activity feed.
Can an AI auto reply tool message people who never DMed me?
No. Instagram's API only lets a business reply to someone who messaged or commented first, within 24 hours. Reachlee's AI is inbound-only by design and never first-contacts anyone. A tool that promises cold outreach is using unofficial access.
How much does Instagram AI auto reply cost?
As of September 2026: AutoDM Pro $13/mo, Reachlee Growth $14/mo (₹799 in India) with 1,000 AI credits, Inrō from €12.99/mo scaling with contacts, Chatfuel's Fuely tiers from roughly $14.99–$49/mo, and Manychat Pro with AI from $39/mo for 2,500 contacts. Verify on each vendor's page; free tiers and bundles change often.
Does Reachlee Free include AI?
No. Free and Pro cover keyword automations, comment-to-DM, story replies, and lead capture without AI. AI Replies, AI Comments, and AI Goals are on Growth ($14/mo, ₹799 in India) and Business ($29/mo, ₹1,499 in India). We say this plainly because a ten-reply free AI allowance is a demo, not a plan.
What happens when I reply to a DM myself?
In Reachlee, a manual reply keeps the AI out of that thread for 48 hours. You can also mute any thread from the Inbox or the Activity feed, or pause the AI globally. Check the takeover rules on any tool you consider; some keep answering over you.
