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.

Private Document AI Search

Users struggle to search, query, and automate work across large private document sets without leaking data or losing context.

In their words

I'm losing hours on something that's supposed to be saving me time.

r/microsoft_365_copilot on Reddit

Worked fine up to 10 docs in data room after which it started making up stuff and apologizing after.

r/private_equity on Reddit

Knowledge is scattered across teams and years

r/CopilotPro on Reddit

I'd like to be able to do basic email summaries daily, scan all emails in a month and generate reports based on keywords etc.

r/LocalLLM on Reddit

We’re spending too much time trying to locate historical documents that we actually need (like board minutes, resolutions, contracts, etc.)

r/nonprofit on Reddit

instead of an assistant that can help me manage years of google docs file clutter, I have "great" ai assistant that can tell me how to drag and drop files on my own

r/GeminiAI on Reddit

It's at the point where it's interfering in our ability to help researchers.

r/Genealogy on Reddit

When I send the PDF to Gemini and ask him what is on page 250 for example, it has no clue.

r/GeminiAI on Reddit

So now I have to read through this document to create a coherent strategy to present to clients.

r/BetterOffline on Reddit

LLMs are fantastic at pulling info out of datasheets / TRMs / errata... I still always manually check everything it produces

r/embedded on Reddit

users just can't find it, search is bad and we don't have any kind of AI assistant on the docs

r/SaaS on Reddit

Finding and summarizing years of historical ppts, word documents with copilot is a godsend

r/biotech on Reddit

multi-hundred page "User Guide" documents that are an absolute chore to read through for anything actually useful to the scenario-of-the-moment

Hacker News

agents quietly acting on stale or misranked sources and nobody noticing until it bites. Pairing each paper with the code that implements it... is the clever bit.

Product Hunt

knowledge workers and teams

Where they talk

  • r/Rag
  • r/LocalLLM
  • r/microsoft_365_copilot
  • r/ClaudeAI
  • r/AI_Agents
  • r/GeminiAI
  • r/ChatGPT
  • r/Paperlessngx

Tools they use today

  • Claude
  • Copilot
  • SharePoint
  • Gemini
  • Qwen
  • Notion
  • Claude Cowork
  • Google Drive

Why those fall short

  • AI is confidently wrong about records, arrangement and citations
  • AI output is illogical, generic and unread by the boss
  • Gemini has no clue what is on page 250; GPT also could not read it
  • internal chatbot can't read markdown; DMS search is awful; only SharePoint/OneDrive connected
  • Mixes up register addresses, pulls info from wrong document revision, hallucinates
