AI Long Context Splitter for fast browser-based work
Split long transcripts, notes, research excerpts, logs, and chat history into AI-ready packets with per-packet instructions and a final synthesis prompt.
中文：把长转写、笔记、研究摘录、日志和聊天记录拆成带每包说明的 AI 资料包，并生成最终综合 prompt。
Example: Paste long material before sending it to ChatGPT, Claude, Gemini, or Codex, then copy numbered packets and a final synthesis instruction.
Where this tool fits in real work
Use cases
- Paste long meeting transcripts, research notes, logs, requirements, or chat history before sending them to an AI assistant.
- Choose a goal and token budget, then create numbered packets with rules that prevent premature global conclusions.
- Copy the final synthesis prompt after all packets have been processed.
Review notes
- Token counts are planning estimates, not model-exact tokenizer output.
- Packet boundaries help preserve source context, but the AI can still miss details. Keep important source material accessible.
- Use smaller packets when you need line-by-line evidence, citations, or careful review.

Use a stricter workflow
If the context includes production secrets, customer records, private research material, or executable scripts, redact first and use a stricter human review workflow.

AI Long Context Splitter questions
Is the token count exact?
No. It is a practical browser estimate for planning chunk size.
Does my long text upload anywhere?
No. Splitting and prompt generation run locally.
Is this tool free?
Yes. The current Toolkits tools are free to use and do not require an account. If advertising is added later, it should be clearly labeled and kept away from primary tool controls.
