Best Alternatives to Grammarly & Scalebrowser (12)
+
Consolidating Premium and Business into Grammarly Pro ($12/member/month annual) gives individuals and small teams access to style guides, analytics, and plagiarism/AI detection in one plan.

Limitations
–Month-to-month billing on Grammarly Pro is steep at $30/member/month compared to the $12/member/month annual commitment ($144 billed upfront).
–Core writing intelligence and style rules remain primarily optimized for English dialects (US, UK, Canadian, Australian, Indian) rather than native multilingual grammar checking.
–Aggressive inline underlines and pop-up agent cards can feel visually intrusive in dense technical documents or code-heavy web editors unless muted per domain.
Scalebrowser
Give every AI agent its own isolated browser with a persistent identity
Persistent profile identity
Each profile is generated from a seed so its identity, cookies and logins persist across restarts, and sites see the same returning visitor rather than a new device.
Isolated browser profiles
One browser per profile means separate logins, cookies and devices that share nothing, making multi-account automation safe to run in parallel.
Built-in sign-in and 2FA handling
Agents get through username and password forms, email confirmation codes, TOTP and SMS two-factor codes, passkeys and permission prompts without stalling.
Human-like input and captchas
Press-and-hold, image grid, slider and rotation captchas are solved through human-like input rather than third-party solving keys.
Strengths & Pros
+Strong focus on persistent, isolated identities so agents stay logged in across runs
+Broad integration surface covering MCP, Python/Node SDKs, REST and direct CDP
+Built-in handling of logins, email codes, TOTP, SMS, passkeys and captchas
+Token-efficient page reading that only reports what changed between steps
+
Detailed run trails with screenshots make debugging agent runs easier
Limitations
–Requires installing a desktop app and running it on your own machine, so it is not a purely cloud-hosted service
–Free tier excludes schedules, webhooks, sync and phone approvals
–Paid tiers meter concurrent browsers, machines and profile counts, which can raise costs for large fleets
–Advanced anti-detection features may raise compliance responsibility with target platforms
