## Heptabase

Heptabase is designed for people who want to understand material rather than merely collect it. At its core is a whiteboard where you break any source into cards — by hand or with AI — and then read deeper by following each citation back to its origin. Supported sources include PDFs, web pages, YouTube videos, podcasts, Readwise and Zotero, so research from different places lands in a single visual space. Nested databases, tags and properties then give that material a structure you can reshape as your understanding changes.

AI features are framed as learning aids rather than answer machines. An AI Tutor turns a goal into a personalised course, and AI assist helps process readings and organise cards on the board. For those who already work inside other AI tools, Heptabase exposes your knowledge base through Claude Code, ChatGPT, Codex and Grok Bot, plus a plugin, MCP server and CLI, so notes can be queried from the assistant you already use.

The practical basics are covered too: a block editor with daily journals, bi-directional links and web clipper; PDF highlight and annotation; offline access; mobile apps; and real-time collaboration for co-annotating boards. Heptabase offers a 7-day trial across mobile and desktop and positions itself as a long-term knowledge home rather than a quick note dump.

**Pricing & Plans:** Heptabase offers a 7-day free trial, with paid subscription plans published on its pricing page covering individual use. Refer to the pricing page itself for current figures.

- **Whiteboards for breaking down sources:** Split PDFs, web pages, YouTube videos, podcasts and Readwise or Zotero items into cards and read deeper through every citation.
- **AI Tutor and AI-assisted reading:** Turn any goal into a personalised course and process readings with AI help before arranging ideas on the board.
- **Nested databases, tags and properties:** Give your knowledge a structure that can be reworked as you learn, using nested tags and properties rather than flat folders.
- **Works with the AI tools you already use:** Query your knowledge base from Claude Code, ChatGPT, Codex or Grok Bot through the plugin, MCP server and CLI.
- **PDF annotation, offline access and collaboration:** Highlight and annotate PDFs, work offline, sync in real time and co-annotate boards with other people on desktop and mobile.

**Strengths:** Whiteboard-plus-database model suits understanding, not just storage; Ingests PDFs, web pages, YouTube, podcasts, Readwise and Zotero; Integrates with Claude Code, ChatGPT, Codex and Grok through plugin, MCP and CLI; Offline access, mobile apps and real-time collaboration included

**Limitations:** Whiteboard metaphor takes time to learn if you are used to linear note apps; Only a 7-day trial before committing to a paid plan; Heavy canvases can become unwieldy without disciplined card naming

## Ideaflow

Ideaflow is a deliberately stripped-down notebook. Instead of folders, databases and formatting toolbars, it gives you an almost instant writing surface where you type a thought and move on. Everything you capture lands in a single, chronological, searchable stack, so there is no filing decision to make in the moment and no place for an idea to get lost.

The product's angle is speed and recall rather than heavy structuring. Notes sync across the web app and mobile browsers so an idea captured on a phone is waiting on the desktop, and search is designed to surface a half-remembered fragment rather than requiring you to recall exact wording or location. Ideaflow also exposes a connector that lets Claude and ChatGPT read from your notebook, so the notes you accumulate can become context for AI-assisted thinking.

Ideaflow is aimed at people who generate more ideas than they can organize — founders, writers, researchers and product people who want a frictionless inbox for thinking. It is available on Chrome and Safari on both desktop and iOS, with a free tier to start and paid plans for heavier use.

**Pricing & Plans:** Ideaflow offers a free tier to get started, with paid subscription plans for additional capacity and features. Check the official site for current pricing.

- **Instant capture:** A minimalist writing surface that opens and records a thought with almost no friction, so ideas are saved before they slip away.
- **Searchable note stack:** Every note flows into one chronological, searchable stack, removing folders and filing decisions while keeping everything findable.
- **Cross-device sync:** Notes captured in the Chrome or Safari web app and on iOS are synced, so the same stack is available wherever you write.
- **Claude and ChatGPT connector:** A connector lets supported AI assistants read from your notebook, turning accumulated notes into usable context for AI conversations.
- **AI-assisted recall:** Search is tuned for recovering loosely remembered fragments rather than requiring exact keywords or a remembered location.

**Strengths:** Extremely low-friction capture with no folder or tag decisions up front; Notes accumulate in one chronological, easily searchable stack; Connector lets Claude and ChatGPT draw on your own notebook; Works in Chrome and Safari on both desktop and iOS

**Limitations:** Minimal structure is a poor fit if you rely on hierarchical folders or databases; Collaboration and team workflows are not a focus; Some advanced capability sits behind paid plans
