Read full description

BibKit is a focused, modern citation manager designed for iPad. FREE PLAN Use every citation tool with a library of up to 10 references. No subscription is required to try BibKit. A BibKit Yearly subscription unlocks an unlimited library across iPad and Mac. IMPORT REFERENCES Import PDF and BibTeX files directly from the Files app. BibKit extracts available citation information and lets you review the result before adding it to your library. LOOK UP PAPERS Add a reference by entering any of the following: β€’ A DOI, such as 10.1016/j.mechmat.2019.103215 β€’ An arXiv identifier, such as 2503.12692v1 β€’ An arXiv abstract or PDF URL β€’ A HAL identifier, such as hal-01234567 β€’ A HAL URL, such as https://hal.science/hal-01234567 β€’ A ScienceDirect article URL containing a recognizable article identifier For publisher pages other than supported ScienceDirect links, enter the publication's DOI instead. When an arXiv preprint has a published version, BibKit can present both records so you can choose the version that belongs in your library. REVIEW AND EDIT Inspect extracted metadata before saving. Edit titles, authors, publication years, journals, volume and issue information, page ranges, publishers, DOI values, arXiv identifiers, URLs, and citation keys. ORGANIZE YOUR LIBRARY Search your references, mark favorites, apply labels, detect duplicates, retain source information, and undo accidental deletions. FORMAT AND EXPORT Generate consistent citation keys, normalize BibTeX formatting, abbreviate journal names, format author initials, and export selected references or your complete library. CREATE FORMATTED REFERENCES Copy references in APA, MLA, or Chicago style when you need a formatted citation instead of BibTeX. BUILT FOR IPAD BibKit provides a native split-view interface designed for reviewing and managing citations on a larger screen. On supported devices, Apple's on-device language model can assist with extracting citation metadata from PDFs. SUBSCRIPTION INFORMATION BibKit Yearly removes the 10-reference library limit on both iPad and Mac. The subscription costs US$2.99 per year in the United States. Prices may vary by country or region, and the applicable localized price is displayed before purchase. An introductory one-month free trial may be available to eligible new subscribers. Payment is charged to your Apple Account upon confirmation of purchase. The subscription renews automatically unless canceled at least 24 hours before the end of the current subscription period. You can manage or cancel your subscription in your App Store account settings. Existing references remain accessible if the subscription ends.

About

Promptron

Features
Read full description

Promptron is an on-device prompt workspace for turning rough intent into a structured request aligned to the Claude or Codex/ChatGPT product surface you choose. It combines bundled capability guidance, local organization, and reviewable evaluation signals. It does not promise objectively β€œbetter” prompts or guarantee AI output. WRITE FOR THE TARGET YOU CHOOSE β€’ Choose a Claude or Codex/ChatGPT target independently from the provider that writes the prompt. β€’ Use bundled, target-specific capability guidance. β€’ Review structured sections, compatibility checks, and transparent static or model-assisted evaluation signals. BRING YOUR OWN KEY β€’ Add an Anthropic or OpenAI API key in Settings. β€’ Requests go directly from your device to the matching provider. Promptron has no model-request proxy. β€’ If both providers are configured, an allowed fallback provider can still prepare the selected target prompt without changing its target guidance. β€’ Provider usage is billed separately under your Anthropic or OpenAI account. PRIVATE BY DESIGN β€’ Projects, conversations, generated prompts, scores, and local profiles stay on your device. β€’ Provider keys are stored separately in Keychain. β€’ Promptron contains no advertising, Promptron analytics, or cross-app tracking. β€’ Before a provider first receives content for the current local profile, Promptron explains what may be sent and asks for permission. Anthropic and OpenAI permissions are separate and revocable. WORK YOUR WAY β€’ Organize conversations in an on-device workspace. β€’ Add selected files, images, or web references when relevant. β€’ Use on-device dictation where the language and device support it. β€’ Copy results. Pro adds additional prompt forms, full bundled retrieval, multi-project organization, live evaluation, and HTML export. PROMPTRON PRO Promptron Pro Monthly is a one-month, auto-renewable subscription that unlocks app features. It does not include Anthropic or OpenAI usage. The localized price is shown before purchase. Payment is charged to your Apple Account at confirmation. The subscription renews automatically unless canceled at least 24 hours before the end of the current period. Manage or cancel through your Apple Account. Restore Purchases is available in the Pro screen. AI output and evaluation signals may be inaccurate and are not professional advice. Verify results before relying on them.
