An AI That Actually Knows What You've Saved
Not another generic chatbot guessing at the internet. SnapStash AI indexes everything in your stash with retrieval-augmented generation, groups related items into collections, and answers your questions with cited sources from your own captures.
What Makes an AI a Second Brain Instead of a Stranger
A generic large language model is a stranger with confident opinions. It has not read your meeting notes, your highlighted PDFs, or that competitor screenshot from last Tuesday. Ask it about your own knowledge and it will either decline or invent. Neither is what a second brain should do.
SnapStash AI is built on retrieval-augmented generation. Every screenshot, link, and PDF you save is parsed, embedded, and indexed into a private File Search store alongside the OCR text and summary. When you ask a question, the system retrieves the most semantically relevant items from your stash first, then asks the language model to answer using only that retrieved context — with citations back to the original items.
Collections take this further by letting you scope the AI's memory. A collection is a project-aware grouping — your dissertation lit review, a single client engagement, a course's semester. Ask a question inside a collection and the retrieval is bounded to that body of work. The AI stops mixing your week-old marketing screenshots into a question about ancient philosophy.
Summaries, tags, and connections fall out of the same pipeline. Every saved item ships with a one- to two-sentence summary and inferred tags as soon as analysis finishes. Over time the AI surfaces connections — two screenshots about the same topic saved months apart, a paper that contradicts an earlier one, a recurring pattern across competitor captures. That is the second brain emerging from data, not configuration.
RAG
every chat answer grounded in retrieved sources, not free recall

“We explore retrieval-augmented generation — RAG — models which combine pre-trained parametric and non-parametric memory for language generation. RAG models generate more specific, diverse and factual language than parametric-only baselines.”

How AI That Remembers Works
Index on Save
Each new item is OCR'd, summarized, tagged, embedded, and uploaded to a per-user File Search store. Nothing happens at query time except retrieval — the heavy work runs once, at save.
Retrieve the Right Context
Your question is matched against the embedded stash. The top-ranked items become the working context — optionally filtered by collection, tag, or date — before the language model sees a single token of the answer.
Answer With Cited Sources
The AI replies grounded in the retrieved items, with inline citations linking back to the original screenshots, links, or PDFs. Verify, drill down, or follow up — the source trail is always one tap away.
Where AI That Remembers Earns Its Keep
Researchers Chatting With Their Lit Review
Ask 'what does this collection say about replication failures in fMRI studies?' and get an answer drawn from your own saved papers — with citations back to the exact screenshots you highlighted.
Learn moreMarketers Asking the Competitive Set Directly
Drop competitor screenshots into a collection across the quarter, then ask 'how has Linear changed their pricing copy?' The AI compares what you've captured over time and points back to the dates.

Ask the AI to generate practice questions from the screenshots in your course collection. Because retrieval is the source, every answer is checkable against your actual lectures and readings.

ChatGPT answers from its training data and whatever you paste into the prompt. SnapStash AI retrieves from a private, per-user index of your own captures first, then asks the model to answer using only that retrieved context — with citation links back to the exact items. The difference is whether the AI's memory is yours or a stranger's.
RAG dramatically reduces hallucination by grounding answers in retrieved sources rather than the model's free-form recall, but no system eliminates it entirely. Every SnapStash answer comes with citations to the underlying items so verification is one tap away. When retrieval returns nothing relevant, the AI says so instead of inventing.
AI search returns ranked items — a list of the screenshots, links, or PDFs most relevant to a query. AI chat returns a synthesized answer — a paragraph or comparison drawn from those items, with citations back to them. Search is for 'show me'; chat is for 'tell me'.
