1. Document Extraction & Spreadsheets: Siftspindle
Turn PDFs, Invoices, and Photos into Excel & JSON
While general chatbots can answer questions about text, extracting structured, multi-column financial tables and invoices into clean Excel spreadsheets (.xlsx) usually requires expensive enterprise software. Siftspindle bridges this gap for free.
Every account receives 10 free extractions per month. You upload an invoice, receipt, or tabular PDF (up to 25 MB), specify the exact columns or fields you need, and receive validated JSON or downloadable Excel spreadsheets in seconds.
Unlike legacy OCR engines, Siftspindle reads borderless tables, hand-tilted smartphone photos, and multi-page ledgers with high accuracy. All uploaded documents are automatically purged after approximately 24 hours, guaranteeing zero AI model training on your private files.
Key Advantage
10 free extractions every calendar month with zero credit card required, instant Excel export, and automatic 24-hour document purge.
2. Conversational AI & Writing: Claude & ChatGPT
Nuanced Reasoning, Artifacts, and General Inquiries
For long-form writing, document analysis, and coding, Anthropic’s Claude (claude.ai) offers the highest quality free conversational tier. Its interactive Artifacts panel lets you view, test, and render HTML websites, SVG diagrams, and code snippets side by side with your chat.
For broad web research, spreadsheet data analysis, and custom GPTs, OpenAI’s ChatGPT (chatgpt.com) free tier remains a versatile Swiss army knife with built-in internet browsing.
3. Research & Grounded Fact-Checking: Perplexity & NotebookLM
