Split without losing the thread.
Local-firstTurn long text, code, Markdown, config files, and supported ZIPs into clean, copy-ready parts, especially useful for AI chats. Keep the full context. Send it in sequence.
Runs entirely on your device. Nothing is uploaded. No internet required. Operates under an air-gapped, zero-telemetry architecture.Paragraph-, line-, and character-aware splitting keeps content intact. ZIP, PDF, and DOCX files are read locally.

Free text splitter for AI chats
Split long text, Markdown, code, developer configuration files, SVG, web manifests, and supported ZIP archives into smaller parts that are easier to paste into AI chats. File processing stays in your browser.
How to split code for AI
- Paste text or choose a supported text, code, developer file, SVG, or ZIP.
- Choose equal parts or a maximum character size.
- Copy each generated part into your AI chat in sequence.
Frequently asked questions
Why split text or files instead of uploading them directly to an AI chat?
Directly uploading large files often triggers context truncation, hidden document indexing limits, or high token overhead. Splitting large codebases, PDFs, and prompts into structured, sequential blocks helps LLMs retain precise reasoning across the entire context window without amnesia.
Is my proprietary code or confidential document secure with Splitter?
Yes. Splitter operates under a local-first, zero-telemetry architecture. All decompression, parsing, and text segmentation run entirely inside your browser's local sandbox and Web Workers. No file data, text snippets, or analytical payloads ever touch a server.
Are files uploaded?
No. Selected files are read and processed in the browser. There is no file-upload backend in Splitter.
Which developer files are supported?
Splitter supports many programming, markup, configuration, infrastructure, documentation, SVG, and manifest formats, plus common extensionless developer files such as Dockerfile and Makefile.
Why not spreadsheet, image, and video files?
Those formats need additional parsing or OCR capabilities. They are intentionally excluded so the tool stays lightweight, local, and focused on text, code, PDF, and DOCX.
