AskYourPDF

Productivity

AskYourPDF provides a chat interface for asking questions about uploaded documents. It is useful for navigating a report, locating relevant information and understanding dense sections without reading everything in order. Its free plan publishes concrete daily limits and identifies its included model, which makes the allowance relatively easy to compare.

ChatPDF

Productivity

ChatPDF lets you upload a PDF and ask questions about its contents in a conversational interface. It is useful for finding a passage, understanding a document or getting an initial summary. The free service can be started without an account, while registering adds conveniences such as saved history and multi-document conversations.

Fireflies.ai

Productivity

Fireflies records and transcribes meetings and makes the resulting conversations searchable. Its free plan includes real-time notes, limited AI summaries and access to the AskFred assistant. It is useful for building a small searchable meeting record, although storage and AI credit limits matter even when transcription is advertised as unlimited.

Gamma

Productivity

Gamma creates presentations, documents and simple web pages from instructions or source material. It helps turn an outline into a visual first draft that you can edit and export. Its free AI allowance is a starting credit grant, so it is best treated as limited experimentation rather than recurring free generation.
