Devin vs notes.asm

Two fact sheets from our own research, side by side — pricing, platforms, API access and status re-checked by us rather than quoted from the vendors.

The short answer

Free plan: Both — Devin has a free plan, notes.asm is free to use
Public API: Both have one
Higher Trust score: Devin — 84 vs 57 for notes.asm
Best fit: Devin: Engineering teams delegating well-specified tickets such as migrations, test coverage and dependency upgrades · notes.asm: Engineering teams wanting to offload well-scoped tickets to an autonomous agent overnight
Platforms: Devin: Web, macOS, Slack app · notes.asm: Web

What our research says

Devin

Devin is the agent to hand a whole ticket to and walk away from, and the $20 Pro tier makes that affordable to try for the first time. The quota is the catch: a long autonomous session can exhaust a plan quickly, and once it does you are paying API rates, so it suits teams that batch well-scoped tasks rather than developers who want a tireless pair programmer in the loop.

Pros

End-to-end autonomy: plans, codes, tests and opens the pull request from its own cloud machine
Fans one large task out across parallel agents and manages them itself
Native Slack, Linear, Jira and GitHub integration plus Desktop and CLI clients
Entry price dropped to $20 a month, far below the original enterprise-only positioning

Cons

Quotas are described only qualitatively ('light', 'generous'), so cost per task is hard to predict
Overage is billed at API pricing, which is where a runaway agent session gets expensive
Team tier adds a flat $80 a month on top of $40 per full user
Pages are heavily client-rendered; the terms live on cognition.com, not devin.ai

notes.asm

notes.asm goes further than a code-completion assistant: it takes a ticket, ships a PR, and has a second agent QA that PR in a real browser before a human looks at it. Being free during alpha makes it worth trying, but alpha also means the reliability and pricing that will apply later aren't settled yet.

Pros

A second agent QAs each PR against a real preview deploy with screenshots and video
Per-workspace memory means later jobs skip re-discovering login flows and conventions
Understands ticket dependencies and waits rather than creating merge conflicts

Cons

Alpha-stage product, pricing and long-term reliability aren't established yet
Site blocked direct automated access during this research, so some detail relies on indexed content rather than a direct read

Which one fits

Choose Devin if you need

Engineering teams delegating well-specified tickets such as migrations, test coverage and dependency upgrades
Organisations that want agents assigned from Slack, Linear or Jira and reviewed as pull requests
Large codebases where a task can be fanned out across parallel cloud agents

Choose notes.asm if you need

Engineering teams wanting to offload well-scoped tickets to an autonomous agent overnight
Teams already using Claude via MCP who want a coding agent wired in directly
Projects where PR review time is a bottleneck and automated QA screenshots would help
