What The Diff
What is What The Diff?
What The Diff plugs into GitHub or GitLab and reads your pull request diffs to write descriptions, send stakeholder-friendly summaries, and suggest inline code refactors. You connect your account, and the assistant drafts PR comments from the actual code changes so reviewers spend less time decoding what changed.
Most AI code tools focus on writing new code inside your editor. What The Diff sits on the review workflow instead, turning diffs into plain-language updates for non-technical teammates, weekly progress reports, and public changelogs with a JSON feed. Reviewers can also comment with /wtd on specific lines to get one-click refactor suggestions rather than back-and-forth comment threads.
It fits engineering teams that want faster reviews without losing visibility for product managers or founders who do not read diffs daily. The pricing page says average pull requests use about 2,300 tokens, and the free tier covers roughly 10 PRs per month with unlimited repositories.
Tabnine
What is Tabnine?
Tabnine is a code assistant that runs inside your IDE with inline completions, multi-line function suggestions, and chat grounded in your repository context. It connects to GitHub, GitLab, Bitbucket, or Perforce so suggestions reflect your architecture instead of generic public code patterns. Teams can deploy it as SaaS, in a VPC, on-premises, or fully air-gapped with zero code retention policies.
Most coding copilots optimize for speed on public repos, while Tabnine sells enterprise control: centralized governance, provenance tracking, SSO, and model choice across OpenAI, Anthropic, Google, Meta, and Mistral endpoints. The Agentic Platform adds CLI agents, MCP tool access, and the Enterprise Context Engine for Jira and Confluence-aware workflows. Tricentis acquired Tabnine in 2025, positioning it inside broader quality-engineering stacks.
Engineering teams in regulated industries use Tabnine when privacy and audit trails matter as much as autocomplete speed. Code Assistant costs $39 per user per month on annual billing, and the Agentic Platform with context engine and CLI agents costs $59 per user per month.
