Real AI agent use cases, with sources and setup prompts

Read long AI chats sideways so each answer is its own page

Sidelong lays a chat out sideways: each question and answer is a page, older pages collapse into colored strips, and color encodes topic so follow-ups share a thread color. It runs on the Claude Code CLI you are already logged into, with topic embeddings from a local Ollama model.

Set it up

  1. Gather your sources

    Collect the papers, notes, links or files you want to work from in one place.

  2. Load them into the tool

    Open Claude Code, Ollama and add your sources. Keep the original files so you can check claims later.

  3. Ask focused questions

    Ask for summaries, comparisons or connections with citations to the source passages.

  4. Verify and save

    Spot check claims against the sources, then save the output as notes you can reuse.

Copy the full setup prompt

Paste into your agent and it will walk you through the setup, asking before anything that sends, posts or spends.

Please:
1. Ask me 3 short questions about my situation (accounts I have, budget, what I want the output to look like).
2. Propose a step-by-step plan using these tools or cheaper alternatives, with the time and cost of each step. Use official pricing pages; say "check pricing" if unsure.
3. Then do the setup with me one step at a time, waiting for my OK before anything that sends messages, posts publicly, spends money or deletes data.
4. Finish with a checklist to run it again next time.
