Claude review

Claude is a general AI assistant, but its document handling is what puts it first here. Anthropic's help center says chat uploads accept PDFs up to 1,000 pages and 500MB per file, with up to 20 files in one chat. On PDFs of 100 pages or fewer, Claude reads charts, images and graphics as well as the text, which matters for annual reports, research papers and slide decks where the numbers sit in figures. Files added to a Project stay available across conversations, so a team can keep a contract set or a course reader in one place. Pro costs $17 a month billed annually or $20 monthly, and the free plan also takes uploads. The limits are worth knowing: PDFs longer than 100 pages are read as text only, project files are capped at 30MB each, and free usage resets every 5 hours with a weekly cap. We compared documented features and published prices.
