Keep the quote with its source
Evidence Board collects exact passages across your documents, with topics and notes. Verify each clip against the local source and share a focused Markdown evidence sheet.
• Open a document → Clip evidence. Enter an exact passage of at least three characters and choose its occurrence.
• Save a topic and note with the clip. Open Evidence Board from the library to find and review clips.
• Open a clip to verify its quote and source hash, edit notes, or share the visible board.
Exact case-sensitive matching shows up to 32 occurrences. A source hash identifies the local text version; it is not proof of authorship or truth. Up to 256 clips and 1 MiB are retained. Unavailable or changed sources are reported.
Marginalias is a private reading companion for your own documents. Import text-based PDFs, plain text, or Markdown notes, then use on-device intelligence to summarize, ask questions, and pull out useful structure without sending your content to a developer server.
Build a local library of documents, open the source text whenever you need it, and keep AI output close to the material it came from. Marginalias is designed for focused review, research, note cleanup, study, and document triage.
Features:
- Import text-based PDFs, plain text, and Markdown
- Keep a searchable local document library
- Generate concise document summaries
- Ask questions grounded in document excerpts
- Inspect exact evidence excerpts, character ranges, and PDF pages behind generated claims
- See the retrieved context used for each answer
- Extract key points, action items, outlines, and glossary terms
- Copy and share generated output
- Use light, dark, or system appearance
- Review a bundled sample document before importing your own files
Privacy:
Marginalias does not require an account, does not include analytics or advertising SDKs, and does not collect your documents or AI output. Documents and generated output stay on your device.
Device note:
AI features use Apple on-device intelligence. If Apple Intelligence is unavailable or not enabled, importing and reading documents still work and the app explains the requirement.
