NOT REALLY
why this verdict
Keep paying — Anthropic has not replaced it
Anthropic's version overlaps, but does not finish the notes & knowledge job, so this one still earns its $12/mo.
- A named launch, not a vibe named, unlinked
- Visual sensemaking over documents is a different job from summarising them. Anthropic, June 25, 2024 — no announcement link recorded yet.
- How much of the job it covers not the job editorial call
- Parts of it. The job still needs the tool to get finished.
- Is there a free way to do it? yes
- 1 of 2 listed replacements have a usable free tier: Obsidian Canvas.
- What the call is worth $144/yr
- $12/mo at the entry paid tier — $144 a year per seat.

The backstory
Heptabase puts notes, PDFs and highlights on an infinite whiteboard so you can see how ideas connect. Models summarise documents; they do not build the researcher's mental map. Its users adopted AI as a reading aid and kept the canvas.
