Built for phpBB admins and volunteer moderators who keep a community alive in their spare time, not around the clock
Answers Pulled Straight From Your Threads
Most questions on a forum have already been answered somewhere in the archive — buried three pages deep in a thread from 2019. A member asks "how do I change my avatar?" or "which board do I post my build log in?" and the assistant replies using the discussions, FAQ, and rules already on your board, instead of sending them off to search engines or leaving them waiting for a reply that may never come.
Knows Your Whole Board
Point Asyntai at your forum and it reads your public sections — the FAQ, the rules and announcements, the stickies, and years of accumulated threads. Add a community handbook or a how-to PDF and it learns that too. The result is an assistant that knows your community the way a long-time member does, not a generic bot that only knows what phpBB does in general.
See What Your Members Keep Asking
Read the chat logs and you will see the same gaps surface again and again. Maybe newcomers can never find where to introduce themselves, or half the board is confused about a rule that is buried in a wall of text. That is a free to-do list: pin a clearer post, rewrite a confusing FAQ entry, or split an overgrown board. Your community gets easier to run because you finally know what trips people up.
Lighten the Load on Volunteer Moderators
Your mod team does this for love, not a paycheck, and they cannot all be online at 2am when a new member is stuck on the activation email or cannot work out how to post images. The assistant takes the first pass at these recurring sign-up and how-to questions so your volunteers spend their limited time on the things only a human can do — settling disputes, shaping the culture, and keeping the conversation good.
Fits Your Forum's Look
Set the widget colors to match prosilver or whatever custom style your community runs, choose where it sits, and write a greeting that sounds like your board rather than a corporate help desk. Give it a tone — friendly and informal for a hobby community, more measured for a support forum — and test it before it goes live so it feels like one of your own.

Made for phpBB Communities
Self-hosted, open-source, and run on a shoestring. One footer edit and the assistant is live on every board.
One Footer Edit and Done
Paste a single snippet into your style's overall_footer.html, purge the cache, and the assistant is on every page of your board. No PHP, no database migration, no extension to maintain if you would rather not use one.
Free Plan for Hobby Boards
phpBB costs nothing and so does getting started here. The Free plan gives you 100 messages a month that reset automatically, which is plenty for a small community to try the assistant without ever reaching for a card.
Easy on Cheap Hosting
The AI runs entirely on Asyntai's servers, not yours. That keeps the load off the budget shared host or small VPS that many phpBB boards live on — your forum just loads a lightweight widget and nothing more.
Speaks Your Members' Languages
International community? The assistant detects each member's language and replies in it automatically, so a question asked in German gets a German answer drawn from the same board content.
Follows Your Board's Rules
Give it instructions like "always link to the posting rules for new members" or "tell people to open a thread in Support rather than messaging staff." It applies them consistently in every conversation, so it reinforces how your community actually works.
Sticks to Your Content
It answers only from your threads and uploaded documents. It will not invent board features, speak for your moderators, or wander off-topic. When the archive does not have the answer, it says so and points the member to the right place to ask.
How to Install on phpBB
phpBB has no script box in the admin panel, so you add the assistant by editing your style's footer template — the same place you would add any board-wide script. It takes one paste and a cache purge.
-
1
Sign up and copy your snippet
Create your free Asyntai account, add your board URL so it can learn your content, and copy your snippet from the dashboard.
-
2
Open your style's footer template
Using FTP or your host's file manager, open overall_footer.html in your active style — for the default theme that is styles/prosilver/template/overall_footer.html.
-
3
Paste before the closing body tag
Add the snippet just before the {$SCRIPTS} placeholder near the bottom, which sits right before the closing </body> tag, and save the file.
-
4
Purge the cache
In the Administration Control Panel, run Purge the cache so phpBB picks up the change. The assistant is now live on every board page. (Prefer not to edit templates? Load it as a board-wide extension instead.)

Why phpBB Communities Choose Asyntai
Start free with 100 messages, upgrade only if your community outgrows it
Give Volunteers Their Time Back
The basic sign-up and how-to questions get handled for you, so the people who run your board for free can spend their hours on real moderation and conversation instead of repeating the same first-day instructions to every new arrival.
Help Newcomers Stick Around
A lot of would-be members give up at the door — confused about activation, unsure where to post, scared off by a wall of rules. An assistant that greets them and answers that first nervous question turns more lurkers into registered, posting members.
Fits a Zero-Budget Community
Many phpBB boards run on donations or the admin's own pocket. The Free plan stays free, the AI runs off-site so it does not strain your hosting, and you only ever pay if your community grows big enough to need more.

How an AI Assistant Helps phpBB Communities
The Quiet Strength of a phpBB Board
phpBB has outlasted nearly every shiny platform that promised to replace the humble forum. It is free, open-source, self-hosted, and you own every byte of it — no monthly SaaS bill, no vendor that can pull the rug, no algorithm deciding who sees what. Communities built on it tend to be labors of love: a niche hobby, a regional interest group, a long-running support board kept going by a handful of people who care. That independence is the whole point, and an AI assistant should respect it rather than drag you back toward the walled gardens you deliberately left behind.
The trade-off for that independence is that everything lands on a small, unpaid team. There is no support department, no shift rota, no budget for staff. When a member gets stuck at midnight, the answer waits until an admin happens to log in. Asyntai slots into that gap without changing the nature of your board — it lives in your footer template, learns from your own threads, and answers in your own voice while your people sleep.
Your Archive Is Already an Encyclopedia
A forum that has been running for a few years is sitting on an enormous, hard-won body of knowledge. Every fix, every recommendation, every long debate about the best way to do something is in there. The problem is that it is scattered across thousands of posts, and the board's own search can be unforgiving — a newcomer rarely knows the right jargon to find what they need. So the same question gets asked for the hundredth time, and a regular sighs and links the old thread yet again.
Asyntai reads that archive and turns it into something a member can simply ask. Instead of guessing keywords, they type their question in plain language and get an answer assembled from the very discussions your community already had, ideally with a pointer back to the original thread. The decades of accumulated wisdom on your board stops being buried and starts being usable, which is exactly what a knowledge community is supposed to be.
Protecting Your Volunteers From Burnout
Moderator burnout is the quiet killer of forums. People sign up to nurture a community they love and slowly find themselves drowning in the same dozen routine questions, day after day, with no pay and little thanks. When a key volunteer finally walks away, the board often goes with them. Keeping that small team motivated is arguably the single most important thing an admin can do.
Handing the repetitive groundwork to an assistant changes the math. The "how do I reset my password" and "where do I post this" messages get fielded automatically, leaving your moderators free for the work that genuinely needs a person — defusing a heated thread, welcoming a promising new voice, steering the direction of the community. Their time is spent on the parts of the job that are rewarding, which is how you keep good volunteers for the long haul.
Winning Over the Nervous Newcomer
The hardest moment in a forum's life is the first five minutes of a new member's. Registration emails land in spam, the rules read like a legal document, and it is never obvious which of forty boards a question belongs in. Plenty of people who would have become valued regulars give up right there and never post at all. An old, established community can feel intimidating from the outside even when it is warm on the inside.
A friendly assistant on every page softens that first encounter. It can walk someone through activation, explain the posting rules in a sentence, and point them to the right board for their introduction — patiently, at any hour, without the fear of looking foolish in front of the whole community. Lowering the barrier at the door means more of your visitors actually register, post, and stick around, which is the lifeblood every forum depends on.
Easy to Add, Easy to Own
Because phpBB is self-hosted, you add the assistant the way you would add any board-wide script: by editing your style's overall_footer.html and dropping the snippet in before the closing body tag, then purging the cache so the change takes. If you would rather not touch template files at all, you can load it through a board-wide extension instead. Either way it is a one-time job, and nothing about your existing setup, database, or hosting needs to change.
From then on you shape the assistant entirely from the Asyntai dashboard — uploading a community handbook, adjusting its tone, adding rules about what it should and should not say. It costs nothing to start, the AI runs on Asyntai's infrastructure rather than your modest hosting, and you remain fully in control of your board, exactly as you were before. For a community that chose phpBB precisely to stay independent, that combination is the point.
