Launch week: every idea card is free.Get Pro

SaaS ideas, mined from what people actually complain about.

Every idea comes from real Reddit posts, was researched against today's competitors, and survived an independent skeptic before it made the list.

Stale RAG Knowledge Retrieval

AI and RAG systems struggle to retrieve accurate, current, and relationship-aware knowledge because documents are scattered, versioned inconsistently, and go stale without maintenance.

In their words

someone could make a fortune if they invented a program that deletes repeat emails in doc review so that we don’t have to review the same thread 27 different times

r/Lawyertalk on Reddit

I need provenance: which passage is the first occurrence vs which is a later description of it.

r/ObsidianMD on Reddit

Only drawback is the generation which is llm based itself for the documents part which has a cost and bias factor attached to it.

r/developersIndia on Reddit

What I need is an unattended verification step in a pipeline running over thousands of articles.

r/Anthropic on Reddit

users just mash the search bar with 1 or 2 vague words, forcing the serverless functions to do massive fuzzy lookups

r/nextjs on Reddit

most people just search one or two words. so feels like helping ppl know what to search for is the actual thing that’s needed

r/javascript on Reddit

In real technical environments, the answer to a single question is scattered across multiple formats.

r/Rag on Reddit

I regularly work on corpuses in the hundreds of billions of documents. There is no plausible future where a context window holds an large org's entire corpus.

r/Rag on Reddit

How are you checking that trace clusters reflect real intent instead of surface wording and who owns the taxonomy once it starts changing?

r/customerexperience on Reddit

llm-wiki must have a git mechanism to roll back safely, which is missing from the day-0 design

r/LocalLLaMA on Reddit

one retrieval strategy for every use case was the wrong call early on and cost real rework to unwind

r/mlops on Reddit

I really need it to get deep into detail on what goes on each slide, and to do that, it needs to analyze content from multiple lengthy documents at once.

r/microsoft_365_copilot on Reddit

I think I'd rather, perhaps naively, whitelist wikipedia, reddit, arxiv, some news sources, etc than include everything. Is there nothing out there that does this?

Hacker News

This got expensive fast, so I'm wondering what your approach is to keep costs down across what I imagine is a lot of volume

RAG and AI knowledge teams

Where they talk

  • r/Rag
  • r/LLMDevs
  • r/AI_Agents
  • r/LocalLLaMA
  • r/LangChain
  • r/ClaudeAI
  • r/ClaudeCode
  • r/ContextEngineering

Tools they use today

  • Claude
  • Neo4j
  • pgvector
  • RRF
  • Claude Code
  • SQLite
  • ChatGPT
  • Obsidian

Why those fall short

  • top-5 similar chunks may not retrieve the full chain
  • feeds repeat same kind of content; no tool does the whole thing
  • no incremental indexing; unchanged files are re-embedded every run
  • fuzzy lookups return whole catalog; dedicated search engines shift cost
  • Swapping backends doesn't fix vague user inputs; users still get unfiltered results
