Eraser review

Eraser is an AI-powered diagramming and system-mapping tool for technical teams. It can turn text prompts, code, and uploaded files into diagrams, then let teams edit the results on a visual canvas or refine them through AI chat. The product also includes AI documents and interactive maps, where users can drill from system-level views into services, containers, and components.

For teams maintaining architecture maps, Eraser supports syncing from code, cloud accounts, and internal catalogs. Shared templates, styles, and rules are intended to keep diagrams consistent across a team. Its agent toolkit can create, search, update, and export diagrams through Claude, Cursor, or ChatGPT. The homepage identifies that toolkit—not Eraser’s core product—as open source.

The pricing page lists a free plan, Business, Business Plus, and custom-priced Enterprise. The main pricing question for a switch is not just the per-seat rate: AI credits, data-source limits, and the Business Plus seat minimum can affect the real cost.

Eraser’s appeal is that it combines diagram generation with editing and maintenance, rather than treating a generated diagram as a finished artifact. Teams can start from prompts, code, or files, then revise the result on the canvas or in AI chat. That gives technical users several ways to get from published material to a diagram without requiring every first draft to be drawn by hand.

The system-map features are a useful fit for teams that need to move between high-level architecture and lower-level components. Eraser supports views across systems, services, containers, and components, and the product says maps can sync from code, cloud accounts, and internal catalogs. Shared templates and style rules also give teams a way to standardize diagrams instead of relying on each contributor’s preferences.

The agent toolkit adds another route into the work: according to the product description, Claude, Cursor, or ChatGPT can create, search, update, and export diagrams through it. On Business, the pricing page lists unlimited files, unlimited version history, and 100 AI credits per month. That is a more practical starting point for a small team than the Free plan’s three files and three AI credits.

The free plan is limited: the pricing page lists three files, three AI credits, and seven-day version history. Business raises the ceiling to 100 AI credits per month, but AI use is still capped. Business Plus lists 250 monthly credits; only Enterprise lists unlimited AI credits. Monthly API calls on paid plans are usage-based, and the published pricing does not state their rates.

Seat costs need a close look. Business is $60 per member per month, or $45 per member per month billed annually. Business Plus is $42 per member per month billed annually, but requires at least 10 seats; no monthly Business Plus price is listed. Paid plans charge for each member, while guests are free. That makes Business Plus a poor fit for a small group that wants its higher limits without buying extra seats.

There are also data and model caps below Enterprise. Business includes one Git repo and one data source, with models up to 1,000 rows; Business Plus lists three of each and models up to 5,000 rows. Enterprise pricing is not published, though the plan lists custom hosting, SCIM provisioning, and SIEM logging. We’d check those limits and the seat minimum before switching.

Eraser has a free plan, but its limits are tight: 3 files, 3 AI credits and 7-day version history. Guests are unlimited and free. Business costs $60 per member/month monthly, or $45 per member/month billed annually. It includes 100 AI credits a month, unlimited files and version history, one Git repo and one data source, and models up to 1,000 rows.

Business Plus is $42 per member/month billed annually, with no monthly price listed. It includes 250 AI credits, three Git repos and data sources, models up to 5,000 rows, and SAML SSO. The catch: it requires at least 10 seats, so the annualized minimum is $420 a month. That’s a higher commitment than Business for a small team, even though its per-seat annual price is lower. Enterprise pricing is not published. Paid plans charge per member, while guests are free; API calls are usage-based on paid plans. Check your expected seat count, AI use and API usage before comparing the headline prices.

Eraser can build diagrams from prompts, code and uploaded files, and its maps can sync with code, cloud accounts and internal catalogs. That may help teams creating new system maps, but the published materials do not publish a migration process, import compatibility list or details about exporting existing files. The agent toolkit can export diagrams through Claude, Cursor or ChatGPT; export formats and what is included are not specified here.

Before switching, check whether your current diagrams and linked data can move cleanly, and whether you need shared templates, source syncing or AI credits. Those needs can also affect the bill: Business is charged per member, and Business Plus has a 10-seat minimum. The published published material contains no Reddit reports, so we can’t substantiate a claim about why users leave. Price exposure, seat minimums and undocumented migration details are practical issues to investigate—not reported reasons for leaving.
