Syllabi – Open-source agentic AI with tools, RAG, and multi-channel deploy

https://www.syllabi-ai.com/
89•achushankar•3mo ago

Comments

achushankar•3mo ago
Hi HN! I built Syllabi – an open-source platform for creating agentic AI systems that integrate tools, use knowledge bases, and deploy across channels.

The Problem: I kept needing AI that could both answer questions from company knowledge AND take actions (send Slack messages, trigger workflows, call APIs). Existing solutions either don't support agentic tool use well, lock you into their cloud, or require weeks to build from scratch.

What Syllabi Does (Three Pillars):

1. INTEGRATE ANY TOOLS • Call webhooks & custom APIs • Send Slack messages, emails, calendar events • Trigger workflows in external services • Connect YOUR custom tools via API/webhooks • AI intelligently decides WHEN and HOW to use each tool (that's the agentic part)

2. KNOWLEDGE BASE (RAG) • Transform docs, videos, websites into knowledge base • PDFs, Google Drive, Notion, Confluence • Advanced RAG with source citations • Click citations to see exact passages highlighted in original documents • Multi-format processing with smart chunking

3. DEPLOY ANYWHERE • Embed widget on any website • Slack & Discord bots • Microsoft Teams (coming soon) • Standalone web app • REST API for custom integrations • One agent, multiple channels

Key Technical Features: - MIT licensed, self-hosted, privacy-first - Modern AI models (latest GPT-4, GPT-4o, o1 series) - More providers coming (Anthropic, local models) - Agentic tool selection with function calling - Channel-agnostic core with adapter pattern - Async job queue for document processing - Plugin system for custom skills

Tech Stack: Next.js (frontend), Python FastAPI (backend), PostgreSQL, Supabase, OpenAI API

Use Cases: • AI course assistant that answers questions AND books office hours • Support bot trained on docs that can create tickets in Linear/Jira • Team knowledge base in Slack that triggers workflows • API docs helper that generates AND runs code examples

Architecture Highlights: - Modular design with clean separation of concerns - Row-level security for multi-tenancy - Docker deployment for easy self-hosting - Comprehensive API for custom integrations

I started building this 6 months ago because every project seemed to need the same thing: an AI that could access knowledge AND take actions, without vendor lock-in or per-message pricing.

Website: https://www.syllabi-ai.com/ GitHub: https://github.com/Achu-shankar/Syllabi Docs: https://www.syllabi-ai.com/docs

Would love feedback from the HN community – especially on: - Agentic AI architecture approaches - Tool use and function calling strategies - Multi-channel deployment patterns - Self-hosting and security best practices

Happy to answer questions about the tech stack, RAG implementation, agentic tool selection, or anything else!

diffeomorphism•3mo ago
The post title should probably start with "Show HN:".

What kind of security guarantees do you have?

It seems to meet that your "problem" usually is unanswered on purpose:

https://simonwillison.net/2025/Jun/16/the-lethal-trifecta/

This has access to sensitive knowledge, tool use and exfiltration. So, the tech seems nice, but I doubt I could ever get permission to deploy this.

achushankar•3mo ago
Excellent point about the security concerns. You're right that the combination of: - Sensitive knowledge access - Tool use/actions - Potential exfiltration

Is a serious concern, especially in enterprise environments.

Currently, this has: - Row-level security in Supabase - API key auth - Rate limiting

But it does NOT have: - Comprehensive audit logging - Fine-grained permission controls - Tool execution sandboxing - Data loss prevention

You're right that this shouldn't be deployed in production with sensitive data without significant security hardening. I should have been clearer about that.

Thanks for the link to Simon's article - very relevant. This is more suited for learning/experimentation than production use with sensitive data right now.

If anyone wants to work on security features, I'd be happy to collaborate on that!

achushankar•3mo ago
Quick disclaimer: Some features shown on the landing page are still in active development or testing. I wanted to get this in front of the community early to get feedback on direction before polishing everything.

Specifically: - Multi-channel deployment (Slack/Discord) is working but needs more testing - Some integrations (Teams, advanced webhooks) are in progress - Documentation is being expanded

The core functionality (RAG knowledge base, tool use, web deployment, self-hosting) is solid and ready to use.

Would rather launch early and iterate with community feedback than wait for "perfect"! Happy to be transparent about what's ready and what's coming.

grammarxcore•3mo ago
Your README links docs that don’t exist.
vytautask•3mo ago
Congrats! However, it does not look ready to be used. For one, I am missing docker-compose which would spin both frontend and backend with all dependencies. Documentation does not state that but in backend docker-compose file I see a dependency on Redis. Things like that makes it hard for me to try this out (also, not supporting local models - but this might be coming in the future, as you've stated)...
matteomrj•3mo ago
Can I ask if your concern is about the Redis dependency or about the fact that it is not stated in the docs?
achushankar•3mo ago
100% valid criticism. You're right - the setup experience is rough: - Missing unified docker-compose for frontend + backend - Redis dependency not documented - No local model support yet

I was focused on features and neglected the developer experience. That's a big miss.

I'm starting a new job tomorrow and won't have bandwidth to fix these immediately, but I'd love help from the community if anyone wants to contribute: - Unified docker-compose setup - Better documentation - Local model support (Ollama/llama.cpp)

All PRs welcome! Thanks for trying it out despite the rough edges.

nodomain•3mo ago
What is your monetization model, e.g. why should I trust this project to still exist in 6 months?

When will you support AWS Bedrock?

behnamoh•3mo ago
Almost all AI projects start free/open-source to build goodwill and then enshittification happens and they add a "pricing" on the landing page...
brazukadev•3mo ago
It's the modern YC/HN process. There is such a long time I don't see anything interesting here tho
kissgyorgy•3mo ago
It's MIT licensed, can be easily picked up by someone else.
achushankar•3mo ago
Fair question. Honest answer:

Monetization: None planned. This is MIT licensed and I'm starting a new job tomorrow, so I won't have time to develop it commercially.

Why trust it exists in 6 months? You probably shouldn't rely on me maintaining it actively. That's why it's MIT licensed - anyone can fork and maintain it.

AWS Bedrock: Not currently supported. Would love a PR if someone wants to add it!

I'm sharing this more as "here's what I built while learning, maybe it helps someone" rather than "here's a product I'm committed to maintaining."

kissgyorgy•3mo ago
I was excited because it looks really good. I looked into the backend code and it's vibe coded with Claude. All the terrible exception handling patterns, all the useless comments and psychopancy is left there. I can't trust this codebase. :(
achushankar•3mo ago
You're absolutely right and I appreciate the honest feedback.

Yes, a lot of this was AI-assisted coding (Claude/Cursor), and I didn't clean up all the patterns. The exception handling is inconsistent, there are useless comments, and the code quality varies.

I'm the first to admit the codebase needs a lot of work. I was learning and experimenting, and it shows.

If you (or anyone) wants to improve it, I'd welcome PRs! The architecture/approach might be useful even if the implementation is rough.

Thanks for looking at the code and giving honest feedback - this is exactly the kind of thing I needed to hear.

CuriouslyC•3mo ago
Here's the deal with releasing early: You release something simple, something with just the core features, in order to validate (sadly most of that validation will be that your marketing sucks but c'est la vie).

If you already have a "large" product that's just very unfinished, that's not a MVP, you're asking people to be alpha testers. You either need to get it into a better state and make sure the docs and onboarding are exemplary, or break the product out into parts and ship them separately.

cyanydeez•3mo ago
What if you just vibe coded it to the limits of your competency and have no hope of making it beyond MVP
achushankar•3mo ago
You're absolutely right. In hindsight, I should have either: 1. Shipped something much simpler first (just RAG + one integration) 2. Polished this to a better state before sharing

I got excited about the architecture and kept adding features. Classic scope creep. The feedback about breaking it into parts is really valuable - that would have been a smarter approach.

Starting a new job tomorrow, so I can't polish it further right now. But if anyone wants to fork it or collaborate on making it more production-ready, I'd be happy to help review PRs when I can.

Thanks for the honest feedback - exactly what I needed to hear.

achushankar•3mo ago
Hi everyone, thank you for all the feedback! I want to be completely transparent about what Syllabi is and isn't.

HONEST CONTEXT:

This started as a personal learning project 6 months ago. I kept adding features as I learned, and it grew into something I thought might be useful to others. It's far from polished or complete.

I'm the first to admit: • The codebase has issues (yes, lots of AI-assisted code that needs cleanup) • Documentation is incomplete (some links are broken, sorry!) • Security features aren't fully implemented yet • Docker setup needs work (missing unified docker-compose) • Many features are still in testing/progress

I'm starting a new job tomorrow and won't have time to actively develop this for the foreseeable future. Rather than let it sit on my laptop, I wanted to share it with the community in case: 1. Others find it useful as-is for learning/experimentation 2. People want to collaborate and improve it 3. The architecture/approach helps someone building something similar

This is NOT a product I'm trying to sell or a startup. It's MIT licensed specifically so anyone can fork it, improve it, or learn from it.

LOOKING FOR COLLABORATORS:

If anyone wants to actively work on this project, I'd love that! The codebase needs: - Security hardening - Better documentation - Cleaner exception handling - Unified docker-compose setup - Local model support (Ollama/llama.cpp) - Better testing

I'm happy to answer questions about the architecture and will try to review PRs when I can, but I can't commit to active development right now.

Thanks for the honest feedback - it's exactly what I needed to hear. If this helps even one person learn something or sparks ideas for better implementations, that's a win.
